* libm/math/e_sqrt.c (__ieee754_sqrt): Don't truncate constant to
"int".

* or1k/impure.c: Fix initialization of impure ptr

- With the gzll kernel we have two different loading options:
- If the image is loaded to the global memory, the bootstrapping
loads the kernel to local memory. Applications are loaded on
demand. The heap then starts right after bss.
- If the image is pre-loaded to the local memory it includes the
application binaries right after bss. The heap then starts after
the application objects.
- We can check if this is a gzll kernel as it has the string "gzll" at
0x2000. At 0x200c we then find the end of the application objects in
the image. If there is no global memory we set _or1k_heap_start to
this value.
* or1k/boards/optimsoc.S: Heap for gzll kernel
|
|
- Previously the heap started right after the bss section. This can now
be configured by changing the _or1k_heap_start symbol that defaults to
the old value (&end). In board_init_early, we can now set this to
another value.
* or1k/sbrk.c: Allow for different heap start
|
|
- The UART interrupt only handled receiver FIFO full interrupts, but we
also want to handle timeout interrupts.
* or1k/or1k_uart.c: Fix interrupts
|
|
- Properly set the interrupt pending flag in the timer mode register.
* or1k/timer.c: Properly set interrupt flags
|
|
- Store the exception program counter (from EPCR) and exception status
register (from ESR) also during the exception. A runtime system may
replace them thereby to implement a thread switch.
* or1k/exception-asm.S: Store missing state
|
|
- We do not need a red zone here, as we do not operate on the current
stack, but always use the clear exception stack. Also reserve two
extra words for the context to store EPCR and ESR.
* or1k/crt0.S: Fix exception stack frame
* or1k/exception-asm.S: ditto
|
|
- During interrupt handling the PICSR, table pointers and current
interrupt line have been saved in incorrect registers and/or stored on
the stack.
- Save the pointer in r16/r18, PICSR in r20 and the current interrupt
line in r22. Those are callee-saved registers, so that the register
values will be preserved.
* or1k/interruts-asm.S: Change registers to callee-saved.

* fhandler.h (class fhandler_base): Add virtual function
get_io_handle_cyg() to get handle from which OPOST-processed output is
read on PTY master.
(class fhandler_pty_slave): Add variable output_handle_cyg to store a
handle to which OPOST-processed output is written. Add two functions,
i.e., set_output_handle_cyg() and get_output_handle_cyg(), regarding
variable output_handle_cyg. Now, output_handle is used only by native
windows program. The data before OPOST-processing is written to
output_handle and OPOST-processing is applied in the master-side. For a
cygwin process, OPOST-processing is applied in the slave-side, and the
data after OPOST-processing is written to output_handle_cyg.
(class fhandler_pty_master): Add two variables, i.e., io_handle_cyg and
to_master_cyg, to store handles of a pipe through which OPOST-processed
output passes. Add pty_master_fwd_thread and function
pty_master_fwd_thread() for a thread which applies OPOST-processing
and forwards data from io_handle to to_master_cyg. Add function
get_io_handle_cyg() regarding variable io_handle_cyg. Now, the pipe
between io_handle and to_master are used only by native windows program
for applying OPOST-processing in the master-side. For a cygwin process,
the pipe between io_handle_cyg and to_master_cyg is used for passing
through the data which is applied OPOST-processing in the slave-side.
* fhandler_tty.cc (struct pipe_reply): Add member to_master_cyg.
(fhandler_pty_master::process_slave_output): Read slave output from
io_handle_cyg rather than io_handle.
(fhandler_pty_slave::fhandler_pty_salve): Initialize output_handle_cyg.
(fhandler_pty_slave::open): Set output_handle_cyg by duplicating handle
to_master_cyg on PTY master.
(fhandler_pty_slave::close): Close handle output_handle_cyg.
(fhandler_pty_slave::write): Write data to output_handle_cyg rather
than output_handle.
(fhandler_pty_slave::fch_close_handles): Close handle output_handle_cyg.
(fhandler_pty_master::fhandler_pty_master): Initialize io_handle_cyg,
to_master_cyg and master_fwd_thread.
(fhandler_pty_master::cleanup): Clean up to_master_cyg as well.
(fhandler_pty_master::close): Print to_master_cyg as well in debug
message. Terminate master forwarding thread. Close handles
to_master_cyg and io_handle_cyg.
(fhandler_pty_master::ioctl): Use io_handle_cyg rather than to_master.
(fhandler_pty_master::pty_master_thread): Add code for duplicating
handle to_master_cyg.
(fhandler_pty_master::pty_master_fwd_thread): New function for a thread
to forward OPOST-processed data from io_handle to to_master_cyg. This
thread applies OPOST-processing to the output of native windows program.
(::pty_master_fwd_thread): Ditto.
(fhandler_pty_master::setup): Create a new pipe to pass thruegh OPOST-
processed output. Create new thread to forward data from io_handle to
to_master_cyg. Set handle to_master_cyg to tty. Print io_handle_cyg as
well in debug message. Close handles io_handle_cyg and to_master_cyg in
case of error.
(fhandler_pty_master::fixup_after_fork): Set handle to_master_cyg to
tty. Copy handle to_master_cyg from arch->to_master_cyg.
(fhandler_pty_master::fixup_after_exec): Clean up to_master_cyg.
* select.cc: Check handle returned by get_io_handle_cyg() rather than
get_handle().
* tty.h (class tty): Add variable _to_master_cyg to store a handle to
which OPOST-processed data is written. Add two functions,
to_master_cyg() and set_to_master_cyg(), regarding _to_master_cyg.

Selectively using -fomit-frame-pointer when -O is used doesn't make sense
anymore, apparently since gcc 4.6, -O implies -fomit-frame-pointer.
exceptions.cc must be compiled with -fno-omit-frame-pointer on x86, as it uses
RtlCaptureContext, which requires a frame pointer.

On x86_64, RtlCaptureContext() uses fxsave to save FPU/MMX/SSE state.
fxsave requires that the destination address is 16-byte aligned, or it will
fault.
CONTEXT is already annotated __attribute__ ((aligned (16))), do the same with
struct _mcontext.
Rearrange ucontext_t so that it's struct _mcontext element is also correctly
aligned.
* include/cygwin/signal.h (struct __mcontext): 16-byte align.
* include/sys/ucontext.h (ucontext_t): Ditto.
