[PATCH 0/7] Fixes to some gcc 4.5.1 bugs

[PATCH 0/7] Fixes to some gcc 4.5.1 bugs

[Ilya Yanok]

Hi everybody,

It seems like everybody are using GCC 4.6 already but as support for
GCC 4.5.1 is still here I'd like to publish the changes we've done to
GCC 4.5.1 recipe some time ago.

We've incorporated the patches for some know GCC 4.5.1 problems:
 PR44392: Already fixed by arm_bswapsi2 patch but the patch differs
slightly from the one in the gcc tree.
 PR43810: linking with optspace on PowerPC results in undefined
references to _savegpr_* _restgpr_*_x. Added the patch from bugzilla
but the issue is still here.
 PR44290: __naked attribute is broken on ARM.
 PR44606: Wrong SPE floating point during computation (PowerPC).
 PR45094: [arm] wrong instructions for dword move in some cases.
 PR45052: volatile ignored
 PR45886: [ARM] support for __ARM_PCS_VFP predefined symbol

Hope this will be useful for someone.

Regards, Ilya.
 

[PATCH 1/7] gcc_4.5.1: fix arm_bswapsi2.patch

[Ilya Yanok]

Acoording to http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44392
correct fix should be
TARGET_EITHER && (arm_arch6 || !optimize_size)
not
TARGET_EITHER && (arm_arch6 && !optimize_size)

[PATCH 2/7] gcc_4.5.1: add pr43810.patch

[Ilya Yanok]

Add fix for PR43810 as proposed in
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43810

Building on powerpc-eabi* with --enable-target-optspace
still fails for me though.
