Re: RFA: Do not use cmpstrnsi to implement builtin memcmp

Hi Jeff, The point of the patch is that the cmpstrnsi machine pattern should not be used to implement the memcmp builtin function. This is because a string comparison will terminate if two zero bytes are read whereas a memory comparison should continue. OK. Kindof surprised this wasn't deal

Commit: RX: Add support for conditional register moves

Hi Guys, I am applying the patch below on behalf of Renesas. It adds support to the RX backend for conditional register moves. Tested without any regressions on an rx-elf toolchain. Cheers Nick gcc/ChangeLog 2011-08-11 Kazuhiro Inaoka * config/rx/rx.md (movsicc): Allow reg

Re: Commit: RX: Disable extender peepholes at -O3

Hi Paul, It disables the peephole optimizations in the rx.md file that combine a load followed by a zero- or sign- extend operation. The disabling only happens at -O3 (or higher) as although the peepholes reduce the number of instructions they can introduce pipeline stalls that actual

Ping: Re: [backport] arm,rx: don't ICE on naked functions with local vars

Hi Richard, DJ is on vacation at the moment, but he asked me to ping you about backporting this patch: http://gcc.gnu.org/ml/gcc-patches/2011-07/msg02321.html to the 4.5 and 4.6 branches: http://gcc.gnu.org/ml/gcc-patches/2011-07/msg02683.html May I apply the patch there please ? Che

Re: [build] Move unwinder to toplevel libgcc (v2)

Hi Rainer, How should we proceed with this patch, especially given the quite moderate comments from most affected target maintainers? I have no objections to the patch from an ARM or FRV point of view. Cheers Nick
