Hi,
the attached patch fixes two issues with the TX backend optimization
trying to get rid of FPR save/restore operations in some cases.
The first is that the stack pointer might get clobbered on 64 bit if
the backend was able to get rid of all the FPR saves/restores and
these were the only
Hello,
Some of the things I've done in 4.8 to improve SH T bit handling turned
out to produce wrong code. The attached patch fixes that by introducing
an SH specific RTL pass.
Tested on rev 202876 with
make -k check RUNTESTFLAGS=--target_board=sh-sim
Hi,
this error recovery ICE (a low priority regression) can be easily
avoided by checking the TREE_TYPE of exp too. Tested x86_64-linux.
Thanks,
Paolo.

Hi,
this patch makes -Ofast to also imply -mfpmath=sse. It is important win on
SPECfP (2000 and 2006). Even though for exmaple the following
float a(float b)
{
return b+10;
}
results in somewhat ridiculous
a:
.LFB0:
.cfi_startproc
subl$4, %esp
.cfi_def_cfa_offset
... and this is a more straightforward approach. Also tested x86_64-linux.
Thanks!
Paolo.

My change on the probability of builtin_expect does have an impact on
the partial inline (more outlined functions will get inline back to
the original function).
I think this triggers an existing issue.
Dehao will explain this in his coming email.
