Hi all,
I'm using GCC 4.1.2 20070626 on a server with Intel Xeon X5570.
How do I turn on the compiler option for SSE4? I've tried -msse4, -msse4.1 and
-msse4.2, but they all returned the error message cc1: error: unrecognized
command line option -msse4.1 (for whichever option I tried).
Thank

Thanks!
I also find the doc describing the HARD_FRAME_POINTER_REGNUM and

It is really usual way to handle this similar cases.

Is there any obvious reason why this function doesn't enable folding if we're

When optimizing small string copies it's definitely smaller to do this inline

Hi everybody!
I'm working on a pass and I need to handle some pointer expressions.
For example, I have this C-code:
int v[1000];
int *p;
p = v[10];
The problem is that, when I'm trying to parse p = v[10];, I'm not able to
get the array offset (10 in this case).
Namely, for a given
