Ahh, ok. Well, hopefully the code I wrote on the trunk is useful for IRA.

They should be pure though.

Load builtins can't be const since they may return different values on

I am trying to get as close mapping from liveness information ( in

I only define store builtins with def_builtin. The rest will be
defined with def_builtin_const., including load builtins. I want
to make sure that it is OK to do so.
Thanks.

I don't see why they can't be defined as const, the only time I can
think of is when you have -fnon-call-

I've just tested gcc/gfortran with CP2K, which some of you might know from
PR29975 and other messages to the list, and observed some very pleasing
evolution in the runtime of the code. In each case the set of compilation
options is '-O2 -ffast-math -funroll-loops -ftree-vectorize -march=native

GCC is not posting on the mailing list. Please be polite to other

Dear Reader,
A few years ago I had already posted a question about implementing a
metrication tool in GCC, i.e. a tool that can measure several metrics
from the source code. Examples could be, the number of variables,
number of multiplications, number of loops, number of functions, etc.
At that ti

I am trying to look at assembler code, and representing it as C code.
For ia32, x86 platforms,
assembler like the following
ADD eax,ebx;
JO integer_overflow_detected;
How would I represent this in C?

Hi,

Hello,
I am looking at a testsuite failure (wo_prof_global_var.c) in my

during structure optimization. In the code, the structure is split into
two individual fields (D.2240 and D.2242) and they are allocated
separately. But
