This - is supported by the intuition that most source arrays (even more - true of most big source arrays) will be word aligned to begin with. -*/ - - .globl _strrchr - .globl __strrchr - .leafproc _strrchr, __strrchr - .align 2 -_strrchr: -#ifdef __PIC - lda Lrett-(.+8)(ip),g14 -#else - lda Lrett,g14 -#endif -__strrchr: - - ld (g0),g4 # fetch first word - lda 0xff,g7 # byte extraction mask - and g1,g7,g1 # make char an 8-bit ordinal - shlo 8,g1,g2 # broadcast the char to four bytes - or g1,g2,g2 - shlo 16,g2,g5 - or g2,g5,g3 - mov g14,g13 # preserve return address - addo 4,g0,g2 # post-increment src pointer - mov 1,g0 # prepare to return null pointer - mov g3,g6 # prepare to return null pointer - -Lsearch_for_word_with_char_or_null: - mov g4,g5 # copy word - scanbyte 0,g5 # check for null byte - ld (g2),g4 # fetch next word of src - bo Lword_has_null # branch if null found - scanbyte g3,g5 # check for byte with char - addo 4,g2,g2 # post-increment src pointer - bno Lsearch_for_word_with_char_or_null # branch if no copy of char - mov g5,g6 # save word that has char in it (at least once) - subo 4,g2,g0 # save addr of byte after word with char - b Lsearch_for_word_with_char_or_null - -Lword_has_null: - subo 4,g2,g2 # move src pointer back to word with null -Lfind_null: - addo 1,g2,g2 # advance src pointer to byte after current - and g7,g5,g14 # extract next byte - cmpo g1,g14 # is current byte char? - shro 8,g5,g5 # position next byte for extraction - bne 1f # skip if not char sought after - mov g2,g0 # save addr of byte after char - mov g3,g6 # save word of all char to short circuit search -1: cmpobne 0,g14,Lfind_null # is current byte null? - -Lfind_last_char: - rotate 8,g6,g6 # position next highest byte - and g7,g6,g5 # extract byte - subo 1,g0,g0 # move pointer to that byte (or nullify) - cmpobne g5,g1,Lfind_last_char # branch if not at char - - bx (g13) # g0 = addr of char in src (or null);

However it is among the fastest - while also being among the most space-conserving, portable and tunable. - Consistent balance across these factors results in a good general-purpose - allocator. For a high-level description, see - http://g.oswego.edu/dl/html/malloc.html - -* Synopsis of public routines - - (Much fuller descriptions are contained in the program documentation below.) - - malloc(size_t n); - Return a pointer to a newly allocated chunk of at least n bytes, or null - if no space is available. - free(Void_t* p); - Release the chunk of memory pointed to by p, or no effect if p is null. - realloc(Void_t* p, size_t n); - Return a pointer to a chunk of size n that contains the same data - as does chunk p up to the minimum of (n, p's size) bytes, or null - if no space is available. The returned pointer may or may not be - the same as p. If p is null, equivalent to malloc. Unless the - #define REALLOC_ZERO_BYTES_FREES below is set, realloc with a - size argument of zero (re)allocates a minimum-sized chunk. - memalign(size_t alignment, size_t n); - Return a pointer to a newly allocated chunk of n bytes, aligned - in accord with the alignment argument, which must be a power of - two. - valloc(size_t n); - Equivalent to memalign(pagesize, n), where pagesize is the page - size of the system (or as near to this as can be figured out from - all the includes/defines below.) - pvalloc(size_t n); - Equivalent to valloc(minimum-page-that-holds(n)), that is, - round up n to nearest pagesize. - calloc(size_t unit, size_t quantity); - Returns a pointer to quantity * unit bytes, with all locations - set to zero. - cfree(Void_t* p); - Equivalent to free(p). - malloc_trim(size_t pad); - Release all but pad bytes of freed top-most memory back - to the system. Return 1 if successful, else 0. - malloc_usable_size(Void_t* p); - Report the number usable allocated bytes associated with allocated - chunk p. This may or may not report more bytes than were requested, - due to alignment and minimum size constraints. - malloc_stats(); - Prints brief summary statistics on stderr. - mallinfo() - Returns (by copy) a struct containing various summary statistics. - mallopt(int parameter_number, int parameter_value) - Changes one of the tunable parameters described below. Returns - 1 if successful in changing the parameter, else 0. - -* Vital statistics: - - Alignment: 8-byte - 8 byte alignment is currently hardwired into the design. This - seems to suffice for all current machines and C compilers. - - Assumed pointer representation: 4 or 8 bytes - Code for 8-byte pointers is untested by me but has worked - reliably by Wolfram Gloger, who contributed most of the - changes supporting this. - - Assumed size_t representation: 4 or 8 bytes - Note that size_t is allowed to be 4 bytes even if pointers are 8. - - Minimum overhead per allocated chunk: 4 or 8 bytes - Each malloced chunk has a hidden overhead of 4 bytes holding size - and status information. - - Minimum allocated size: 4-byte ptrs: 16 bytes (including 4 overhead) - 8-byte ptrs: 24/32 bytes (including, 4/8 overhead) - - When a chunk is freed, 12 (for 4byte ptrs) or 20 (for 8 byte - ptrs but 4 byte size) or 24 (for 8/8) additional bytes are - needed; 4 (8) for a trailing size field - and 8 (16) bytes for free list pointers. Thus, the minimum - allocatable size is 16/24/32 bytes. - - Even a request for zero bytes (i.e., malloc(0)) returns a - pointer to something of the minimum allocatable size. - - Maximum allocated size: 4-byte size_t: 2^31 - 8 bytes - 8-byte size_t: 2^63 - 16 bytes - - It is assumed that (possibly signed) size_t bit values suffice to - represent chunk sizes. `Possibly signed' is due to the fact - that `size_t' may be defined on a system as either a signed or - an unsigned type. To be conservative, values that would appear - as negative numbers are avoided. - Requests for sizes with a negative sign bit will return a - minimum-sized chunk. - - Maximum overhead wastage per allocated chunk: normally 15 bytes - - Alignnment demands, plus the minimum allocatable size restriction - make the normal worst-case wastage 15 bytes (i.e., up to 15 - more bytes will be allocated than were requested in malloc), with - two exceptions: - 1. Because requests for zero bytes allocate non-zero space, - the worst case wastage for a request of zero bytes is 24 bytes. - 2. For requests >= mmap_threshold that are serviced via - mmap(), the worst case wastage is 8 bytes plus the remainder - from a system page (the minimal mmap unit); typically 4096 bytes. - -* Limitations - - Here are some features that are NOT currently supported - - * No user-definable hooks for callbacks and the like. - * No automated mechanism for fully checking that all accesses - to malloced memory stay within their bounds. - * No support for compaction. - -* Synopsis of compile-time options: - - People have reported using previous versions of this malloc on all - versions of Unix, sometimes by tweaking some of the defines - below. It has been tested most extensively on Solaris and - Linux. It is also reported to work on WIN32 platforms. - People have also reported adapting this malloc for use in - stand-alone embedded systems. - - The implementation is in straight, hand-tuned ANSI C. Among other - consequences, it uses a lot of macros. Because of this, to be at - all usable, this code should be compiled using an optimizing compiler - (for example gcc -O2) that can simplify expressions and control - paths. - - __STD_C (default: derived from C compiler defines) - Nonzero if using ANSI-standard C compiler, a C++ compiler, or - a C compiler sufficiently close to ANSI to get away with it. - DEBUG (default: NOT defined) - Define to enable debugging. Adds fairly extensive assertion-based - checking to help track down memory errors, but noticeably slows down - execution. - SEPARATE_OBJECTS (default: NOT defined) - Define this to compile into separate .o files. You must then - compile malloc.c several times, defining a DEFINE_* macro each - time. The list of DEFINE_* macros appears below. - MALLOC_LOCK (default: NOT defined) - MALLOC_UNLOCK (default: NOT defined) - Define these to C expressions which are run to lock and unlock - the malloc data structures. Calls may be nested; that is, - MALLOC_LOCK may be called more than once before the corresponding - MALLOC_UNLOCK calls. MALLOC_LOCK must avoid waiting for a lock - that it already holds. - MALLOC_ALIGNMENT (default: NOT defined) - Define this to 16 if you need 16 byte alignment instead of 8 byte alignment - which is the normal default. - SIZE_T_SMALLER_THAN_LONG (default: NOT defined) - Define this when the platform you are compiling has sizeof(long) > sizeof(size_t). - The option causes some extra code to be generated to handle operations - that use size_t operands and have long results. - REALLOC_ZERO_BYTES_FREES (default: NOT defined) - Define this if you think that realloc(p, 0) should be equivalent - to free(p). Otherwise, since malloc returns a unique pointer for - malloc(0), so does realloc(p, 0). - HAVE_MEMCPY (default: defined) - Define if you are not otherwise using ANSI STD C, but still - have memcpy and memset in your C library and want to use them. - Otherwise, simple internal versions are supplied. - USE_MEMCPY (default: 1 if HAVE_MEMCPY is defined, 0 otherwise) - Define as 1 if you want the C library versions of memset and - memcpy called in realloc and calloc (otherwise macro versions are used). - At least on some platforms, the simple macro versions usually - outperform libc versions. - HAVE_MMAP (default: defined as 1) - Define to non-zero to optionally make malloc() use mmap() to - allocate very large blocks. - HAVE_MREMAP (default: defined as 0 unless Linux libc set) - Define to non-zero to optionally make realloc() use mremap() to - reallocate very large blocks. - malloc_getpagesize (default: derived from system #includes) - Either a constant or routine call returning the system page size. - HAVE_USR_INCLUDE_MALLOC_H (default: NOT defined) - Optionally define if you are on a system with a /usr/include/malloc.h - that declares struct mallinfo. It is not at all necessary to - define this even if you do, but will ensure consistency. - INTERNAL_SIZE_T (default: size_t) - Define to a 32-bit type (probably `unsigned int') if you are on a - 64-bit machine, yet do not want or need to allow malloc requests of - greater than 2^31 to be handled. This saves space, especially for - very small chunks. - INTERNAL_LINUX_C_LIB (default: NOT defined) - Defined only when compiled as part of Linux libc. - Also note that there is some odd internal name-mangling via defines - (for example, internally, `malloc' is named `mALLOc') needed - when compiling in this case. These look funny but don't otherwise - affect anything. - INTERNAL_NEWLIB (default: NOT defined) - Defined only when compiled as part of the Cygnus newlib - distribution. - WIN32 (default: undefined) - Define this on MS win (95, nt) platforms to compile in sbrk emulation. - LACKS_UNISTD_H (default: undefined) - Define this if your system does not have a . - MORECORE (default: sbrk) - The name of the routine to call to obtain more memory from the system. - MORECORE_FAILURE (default: -1) - The value returned upon failure of MORECORE. - MORECORE_CLEARS (default 1) - True (1) if the routine mapped to MORECORE zeroes out memory (which - holds for sbrk). - DEFAULT_TRIM_THRESHOLD - DEFAULT_TOP_PAD - DEFAULT_MMAP_THRESHOLD - DEFAULT_MMAP_MAX - Default values of tunable parameters (described in detail below) - controlling interaction with host system routines (sbrk, mmap, etc). - These values may also be changed dynamically via mallopt(). The - preset defaults are those that give best performance for typical - programs/systems. - - -*/ - - - - -/* Preliminaries */ - -#ifndef __STD_C -#ifdef __STDC__ -#define __STD_C 1 -#else -#if __cplusplus -#define __STD_C 1 -#else -#define __STD_C 0 -#endif /*__cplusplus*/ -#endif /*__STDC__*/ -#endif /*__STD_C*/ - -#ifndef Void_t -#if __STD_C -#define Void_t void -#else -#define Void_t char -#endif -#endif /*Void_t*/ - -#if __STD_C -#include /* for size_t */ -#else -#include -#endif - -#ifdef __cplusplus -extern "C" { -#endif - -#include /* needed for malloc_stats */ - - -/* - Compile-time options -*/ - - -/* - - Special defines for Cygnus newlib distribution. - - */ - -#ifdef INTERNAL_NEWLIB - -#include - -/* - In newlib, all the publically visible routines take a reentrancy - pointer.

"Nextchunk" is the beginning of the next contiguous chunk. - - Chunks always begin on even word boundries, so the mem portion - (which is returned to the user) is also on an even word boundary, and - thus double-word aligned. - - Free chunks are stored in circular doubly-linked lists, and look like this: - - chunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ - | Size of previous chunk | - +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ - `head:' | Size of chunk, in bytes |P| - mem-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ - | Forward pointer to next chunk in list | - +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ - | Back pointer to previous chunk in list | - +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ - | Unused space (may be 0 bytes long) . - . . - . | -nextchunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ - `foot:' | Size of chunk, in bytes | - +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ - - The P (PREV_INUSE) bit, stored in the unused low-order bit of the - chunk size (which is always a multiple of two words), is an in-use - bit for the *previous* chunk. If that bit is *clear*, then the - word before the current chunk size contains the previous chunk - size, and can be used to find the front of the previous chunk. - (The very first chunk allocated always has this bit set, - preventing access to non-existent (or non-owned) memory.) - - Note that the `foot' of the current chunk is actually represented - as the prev_size of the NEXT chunk. (This makes it easier to - deal with alignments etc). - - The two exceptions to all this are - - 1. The special chunk `top', which doesn't bother using the - trailing size field since there is no - next contiguous chunk that would have to index off it. (After - initialization, `top' is forced to always exist. If it would - become less than MINSIZE bytes long, it is replenished via - malloc_extend_top.) - - 2. Chunks allocated via mmap, which have the second-lowest-order - bit (IS_MMAPPED) set in their size fields. Because they are - never merged or traversed from any other chunk, they have no - foot size or inuse information. - - Available chunks are kept in any of several places (all declared below): - - * `av': An array of chunks serving as bin headers for consolidated - chunks. Each bin is doubly linked. The bins are approximately - proportionally (log) spaced. There are a lot of these bins - (128). This may look excessive, but works very well in - practice. All procedures maintain the invariant that no - consolidated chunk physically borders another one. Chunks in - bins are kept in size order, with ties going to the - approximately least recently used chunk. - - The chunks in each bin are maintained in decreasing sorted order by - size. This is irrelevant for the small bins, which all contain - the same-sized chunks, but facilitates best-fit allocation for - larger chunks. (These lists are just sequential. Keeping them in - order almost never requires enough traversal to warrant using - fancier ordered data structures.) Chunks of the same size are - linked with the most recently freed at the front, and allocations - are taken from the back. This results in LRU or FIFO allocation - order, which tends to give each chunk an equal opportunity to be - consolidated with adjacent freed chunks, resulting in larger free - chunks and less fragmentation. - - * `top': The top-most available chunk (i.e., the one bordering the - end of available memory) is treated specially. It is never - included in any bin, is used only if no other chunk is - available, and is released back to the system if it is very - large (see M_TRIM_THRESHOLD). - - * `last_remainder': A bin holding only the remainder of the - most recently split (non-top) chunk. This bin is checked - before other non-fitting chunks, so as to provide better - locality for runs of sequentially allocated chunks. - - * Implicitly, through the host system's memory mapping tables. - If supported, requests greater than a threshold are usually - serviced via calls to mmap, and then later released via munmap. - -*/ - - - - - - -/* sizes, alignments */ - -#define SIZE_SZ (sizeof(INTERNAL_SIZE_T)) -#ifndef MALLOC_ALIGNMENT -#define MALLOC_ALIGN 8 -#define MALLOC_ALIGNMENT (SIZE_SZ + SIZE_SZ) -#else -#define MALLOC_ALIGN MALLOC_ALIGNMENT -#endif -#define MALLOC_ALIGN_MASK (MALLOC_ALIGNMENT - 1) -#define MINSIZE (sizeof(struct malloc_chunk)) - -/* conversion from malloc headers to user pointers, and back */ - -#define chunk2mem(p) ((Void_t*)((char*)(p) + 2*SIZE_SZ)) -#define mem2chunk(mem) ((mchunkptr)((char*)(mem) - 2*SIZE_SZ)) - -/* pad request bytes into a usable size */ - -#define request2size(req) \ - (((long)((req) + (SIZE_SZ + MALLOC_ALIGN_MASK)) < \ - (long)(MINSIZE + MALLOC_ALIGN_MASK)) ?

The substring converted is the longest initial - subsequence of <[str]>, beginning with the first - non-whitespace character, that has the format: - .[+|-]<[digits]>[.][<[digits]>][(e|E)[+|-]<[digits]>] - The substring contains no characters if <[str]> is empty, consists - entirely of whitespace, or if the first non-whitespace - character is something other than <<+>>, <<->>, <<.>>, or a - digit. If the substring is empty, no conversion is done, and - the value of <[str]> is stored in <<*<[tail]>>>. Otherwise, - the substring is converted, and a pointer to the final string - (which will contain at least the terminating null character of - <[str]>) is stored in <<*<[tail]>>>. If you want no - assignment to <<*<[tail]>>>, pass a null pointer as <[tail]>. - <> is identical to <> except for its return type. - - This implementation returns the nearest machine number to the - input decimal string. Ties are broken by using the IEEE - round-even rule. - - The alternate function <<_strtod_r>> is a reentrant version. - The extra argument <[reent]> is a pointer to a reentrancy structure. - -RETURNS - <> returns the converted substring value, if any. If - no conversion could be performed, 0 is returned. If the - correct value is out of the range of representable values, - plus or minus <> is returned, and <> is - stored in errno. If the correct value would cause underflow, 0 - is returned and <> is stored in errno. - -Supporting OS subroutines required: <>, <>, <>, -<>, <>, <>, <>. -*/ - -/**************************************************************** - * - * The author of this software is David M.

-; -; NOTE: The 29027 is the floating point coprocessor for the 29000. -; It contains 8 floating point registers FP0 to FP7. Three of -; these, FP0, FP1, and FP2, are currently designated as scratch, -; that is, they will not be preserved across calls. The other -; five contain values that must be saved whenever they are used -; in code, and restored before the exit of the routine. The 29027 -; registers are tagged with a single bit indicating the precision -; of the current value. When numbers are read into the 29027, -; they are always stored in double precision, so that single -; precision values are converted on input. Only the MOVE instruction -; fails to do this automatic widening. If the result from calculations -; in the 29027 ALU (determined by the result precision bit in the -; instruction word) is to be single precision and the result saved in -; an FP reg, the result precision bit from the instruction gets copied -; into the precision bit for the register. If a single precision -; SNaN is saved from the 29027, it will be converted to a double -; precision QNaN. Along the way it will cause an unmasked exception -; when read off the chip and cause changes to the status register. -; So the preservation routine will need to modify the mode register to -; mask off the exceptions, save the state of the status register before -; saving the FP regs, and restore the status and mode registers to their -; original settings when the save is complete. -; -; REFERENCE: The instructions to drive the Am29027 are described in the -; Am29027 manual beginning on page 17.

These macros will be after the entry code for a transcendental -; routine. This entry code will move the original function arguments -; (by value, if the target language is FORTRAN) into the global -; registers t0/t1 and t2/t3 (t0 and t2 for single precision -; routines). -; 2. The sources of all operands will be one register from the -; following list: -; t0 or t2 - the source is one of the original input operands -; rtn0 - the source is rtn0, which should be used as the -; source for all constant values to be sent to the -; AM29027 (when used) -; FP0 - FP7 - the source is one of the fp registers -; 3. The destination of all operations will be a register from the -; following list: -; rtn0 - the destination is the function return value -; FP0 - FP7 - the destination is one of the fp registers -; 4. The additional registers available for temporary use are -; t4, lrp, and slp. -; -; These register definitions are all taken from the file "proregs.a" -; which was supplied by AMD. NOTE that the FP0-FP7 registers, for the -; Am29000 version of the file, overlap with the rtn0-rtn15 registers, so -; that FP0 corresponds to rtn0/rtn1, FP1 to rtn2/rtn3, and so forth. -; - .equ ERROR,0 - .equ NO_ERROR,1 - - .equ DOUBLE_FUNCTION,0 - .equ SINGLE_FUNCTION,1 - - .equ T_OPERATION,0 - .equ Q_OPERATION,1 - - .equ R_SOURCE_29000,0 - .equ R_SOURCE_29027,1 - - .equ S_SOURCE_29000,0 - .equ S_SOURCE_29027,1 - - .equ DESTINATION_29000, 0 - .equ DESTINATION_29027, 1 - -;

For instance, the target board may -have one serial line. - -In this case, the @code{write} system call can be ``hard-wired'' to -always print to the serial device, no matter what the supplied file -handle says. Similarly, the other I/O system calls can be written to -take advantage of a known configuration. - -Note that the library starts up assuming that three files are already -open.

The -@code{crt0} function can take advantage of this and prepare the way -for the libary. - -Another task for @code{crt0} is to call the @code{main} function -provided by the application writer, and also to call @code{exit} if -the main function ever returns. - -@code{exit} tells the operating system that the application has -finished. - - - diff --git a/newlib/libc/sys/sysvnecv70/write.s b/newlib/libc/sys/sysvnecv70/write.s deleted file mode 100644 index 5b4dfb272..000000000 --- a/newlib/libc/sys/sysvnecv70/write.s +++ /dev/null @@ -1,9 +0,0 @@ - - .globl __write - .globl _write -__write: -_write: chlvl #0,#4 - jnl ok - jmp cerror -ok: ret #0 - diff --git a/newlib/libc/sys/tic80/Makefile.am b/newlib/libc/sys/tic80/Makefile.am deleted file mode 100644 index f55a90adb..000000000 --- a/newlib/libc/sys/tic80/Makefile.am +++ /dev/null @@ -1,19 +0,0 @@ -## Process this file with automake to generate Makefile.in - -AUTOMAKE_OPTIONS = cygnus - -INCLUDES = $(NEWLIB_CFLAGS) $(CROSS_CFLAGS) $(TARGET_CFLAGS) - -noinst_LIBRARIES = lib.a - -lib_a_SOURCES = - -# This is a hack to force automake to include a definition for -# COMPILE. -EXTRA_LIBRARIES = libfoo.a -libfoo_a_SOURCES = crt0.c - -all: crt0.o - -ACLOCAL_AMFLAGS = -I ../../.. -CONFIG_STATUS_DEPENDENCIES = $(newlib_basedir)/configure.host diff --git a/newlib/libc/sys/tic80/Makefile.in b/newlib/libc/sys/tic80/Makefile.in deleted file mode 100644 index 21f4afa28..000000000 --- a/newlib/libc/sys/tic80/Makefile.in +++ /dev/null @@ -1,311 +0,0 @@ -# Makefile.in generated automatically by automake 1.3 from Makefile.am - -# Copyright (C) 1994, 1995, 1996, 1997, 1998 Free Software Foundation, Inc. -# This Makefile.in is free software;
