Hi all,
I've committed this on Jiongs' behalf as r212927 with some minor ChangeLog
modifications to make it fit into the 80 character column limit:
2014-07-23 Jiong Wang <jiong.w...@arm.com>
* config/arm/arm.c (arm_get_frame_offsets): If both r3 and other
callee-saved registers are available for padding purpose
and r3 is not mandatory, then prefer use those callee-saved
instead of r3.

* gcc.dg/ira-shrinkwrap-prep-1.c (target): Add arm_nothumb.
* gcc.dg/ira-shrinkwrap-prep-2.c (target): Likewise.
* gcc.dg/pr10474.c (target): Likewise.

Since this commit, I've noticed a few regressions:
gcc.target/arm/pr43920-2.c object-size text <= 54
gcc.target/arm/pr45701-1.c scan-assembler push\t{r3
gcc.target/arm/pr45701-1.c scan-assembler-not r8
gcc.target/arm/pr45701-2.c scan-assembler push\t{r3
gcc.target/arm/pr45701-2.c scan-assembler-not r8
(targets arm-none-linux-gnueabi, arm-none-linux-gnueabihf).
Note that these tests still PASS if one forces -marm or -march=arm-v5t
in the multilib flags, or if the compiler is configured
--with-cpu=cortex-a57 --with-arch=armv8.
Hi Christophe,
Indeed. I noticed these regressions also, and just posted a fix, maybe
during you writing this email:)
Thanks.
