First off, afaict, xc16x support has never been merged into gcc.
Upstream merge isn't strictly required for new ports, but it seems
like people should merge eventually in some shape, and considering
the libgloss port was merged in 2009, ~14 years seems like plenty
of leeway. Which is to say, no one else can seem to build this
which makes updating & testing things very difficult.
Ignoring that, from what I can tell, this port has only ever built
and installed a crt0.o file. It defines libeval.a & libcygmon.a
targets, but nothing depends on them. The SCRIPTS & BSP variables
are always empty. The original port merge define these in the
configure script as substitutes, but never set the vars, so they
were always replaced with nothing.
I actually broke this build 2 years ago when merging the configure
up a level in commit 30f244155b8e82aa948ddcb8f2350654fc1adb92
("libgloss: merge subdirs that have unique makefile_frags up a
level"). I saw that it was exporting a bunch of vars in the
configure script, but never set them, so I incorrectly assumed
they weren't used. Which means the Makefile has been setting them
to invalid values like literal @bsp_list@ and @script_list@.
Considering no one has complained, I have to assume no one cares
about this port, and we can all stop wasting time on it.

Avoid a recursive make to speed things up a bit.
Untested, but follows the same pattern as mn10300, but simpler.

A mn10300-elf build shows installed objects & libs produce same code.

Since $(AS) is the assembler, passing it a list of preprocessor include
flags doesn't make much sense. The files aren't preprocessed which means
`#include` lines aren't respected, and while it would affect `.include`
usage, we never use that, and it's extremely unlikely to change. Plus,
it's extremely unlikely we'd have .s files in common places to include vs
contained entirely within a specific arch dir, and at that point, it can
be included directly (with no flags), or the arch can add the unique set
of include paths that it needs for itself.

This reverts commit 17ac400c11bab30ac2c0bef12cbf7788f0b6f954.
The build failures were due to incorrectly using $(INCLUDES) when
running $(AS). Let's roll this back and drop $(INCLUDES) from the
$(AS) invocations.

- conditionally use -idirafter option for arm
|
|
The libgloss port has been reaching back into newlib internals for a
single header whose contents have been frozen for almost a decade.
To break this backwards libgloss->newlib dependency, move the acle
header to the srcroot include/ so everyone can use the same copy.

The top level dir isn't doing anything interesting, just recursing into
subdirs. So this change isn't terribly exciting. But it sets us up for
doing more fun stuff in follow up commits.
[TODO] Check test targets
|
|
Merge the subdir configure scripts up that only existed to set unique
values for their target/host makefile_frags.
|
|
These subdirs have unique configure scripts to do some compiler tests.
The checks should work for all targets, so hoist them up to the top
libgloss dir. This should allow us to delete these subdir configure
scripts.
It means the top-level gains autoheader support, but that's fine.
It wasn't exporting any defines previously (i.e. -D into CPPFLAGS),
and all of the defines it now exports are only used by code in the
libnosys subdir which was expecting to have a config.h.

The GNU ar has "q" aliased to "r", and we generally want this behavior anyways
(replacing rather than always appending), so change our AR_FLAGS definition.
