gcc/musl: rework SSP-support
|
||||
|
||||
Make musl provide libssp_nonshared.a and make GCC link it unconditionally
|
||||
if musl is used. This should be a no-op if SSP is disabled and seems to be
|
||||
the only reliable way of dealing with SSP over all packages due to the mess
|
||||
that is linkerflags handling in packages.

gcc: prevent the use of LDRD/STRD on ARMv5TE
|
||||
|
||||
These instructions are for 64-bit load/store. On ARMv5TE, the CPU
|
||||
requires addresses to be aligned to 64-bit. When misaligned, behavior is
|
||||
undefined (effectively either loads the same word twice on LDRD, or
|
||||
corrupts surrounding memory on STRD).
|
||||
|
||||
On ARMv6 and newer, unaligned access is safe.
|
||||
|
||||
Removing these instructions for ARMv5TE is necessary, because GCC
|
||||
ignores alignment information in pointers and does unsafe optimizations
|
||||
that have shown up as bugs in various places.

toolchain/gcc: .init and .fini need to pick one ISA
|
||||
|
||||
The .init and .fini sections are built by concatenating code
|
||||
fragments. Putting mips16 code in the middle of a mips32 code block
|
||||
doesn't work. Make gcc built the magic crt stuff in no-mips16 mode.
|
||||
|
||||
This is specific to 4.6-linaro but is probably portable to other gcc
|
||||
flavors. Adding this to the t-libgcc-mips16 makefile fragment is a
|
||||
hack not suitable for pushing upstream, but there is no mips/t-linux
|
||||
or mips/t-uclibc and I am not going to touch gcc/configure for two
|
||||
lines.

Port the mbsd_multi patch from freewrt, which adds -fhonour-copts. This will emit warnings in packages that don't use our target cflags properly
|
||||
|
||||
SVN-Revision: 8256
|
||||
|
||||
This patch brings over a feature from MirBSD:
|
||||
* -fhonour-copts
|
||||
If this option is not given, it's warned (depending
|
||||
on environment variables). This is to catch errors
|
||||
of misbuilt packages which override CFLAGS themselves.
|
||||
|
||||
This patch was authored by Thorsten Glaser <tg at mirbsd.de>
|
||||
with copyright assignment to the FSF in effect.

I talked to Andrew about what files he changed in GCC and created and
|
||||
tested this new patch. Andrew also mentioned changing some assembly
|
||||
files in glibc but I don't see any use of '.section .note.GNU-stack' in
|
||||
any assembly files in glibc (for any platform) so I wasn't planning on
|
||||
creating a glibc to add them to mips glibc assembly language files.
|
||||
|
||||
OK to check in this patch?

gcc: don't clobber stamp-bits with a symlink to itself
|
||||
|
||||
Several versions of gcc have an issue in libstdc++v3 where the build may
|
||||
clobber stamp-bits with a link to itself. This doesn't manifest itself
|
||||
on all systems. On several Ubuntu systems, this doesn't appear to be a
|
||||
problem, but it is an issue on Fedora 16 systems.
|
||||
|
||||
To fix the issue, we'll simply filter out stamp-bits from the symlinks
|
||||
to be generated.
|
||||
|
||||
Note: gcc 4.4.7 is unaffected by this issue, so no fix is necessary
|
||||
there.
