Hello all,
Sorry for my last patch that cause some test regressions. I have correct
it, and it has been tested for aarch64-none-elf on the model.
This patch will replace all explicit calls to gen_rtx_PLUS and GEN_INT
with plus_constant.
OK for trunk?
Kind regards,
Renlin Li

Looks ok to me, but I can't approve it. CC'ing the maintainers...

I've committed the patch as r203108.
Renlin, for future reference: Changelog rules expect two spaces between your
name and the email. So I've committed the patch with the Changelog:
2013-10-02 Renlin Li <renlin.li@arm.com>
* config/aarch64/aarch64.c (aarch64_expand_prologue): Use plus_constant.

Marcus, Renlin,
I'm also seeing issues building an AArch64 Linux toolchain with this patch
applied, so I've reverted it for now.

Hi Renlin,
This patch appears to have caused a number of regressions on
an aarch64-none-elf test run.
I see Internal Compiler Errors along these lines:

with plus_constant.
This has been tested for aarch64-none-elf on the model.
