Hi.
My build from last night failed due to a warning/error.

For this sort of calculation, I would guess not. I would imagine that
on most processors the cost of a single vector instruction is

Hello,
As some folks perhaps have noticed, my effort to make gcc use cfglayout
mode between expand and, roughly, sched1, have stagnated a bit. I am
completely stuck on a problem that I basically can't trigger. In other
words, I *know* I should expect problems if I make a certain change, but

Hello all,
I have a question about retargeting the back-end of GCC 4.1.
Our targeted architecture uses four classes of registers: global ($RG),
locals ($RL), dependents ($RD), shareds ($RS). In total 31 hard
registers available for the all previous classes.
The amount of each register is only k
Hello all,
Dorit Nuzman and I have been collaborating on a plan for a cost model
for the vectorizer. Included below is an overview of the design for
the initial implementation. We would welcome any input those of you
on the list might have.
Thanks in advance for your help.

This is a feature of the ARM ABI you are using. All structures are word

Right, this is not the "spirit" of the GCC regression testsuite.
We instead strive to distill reduced testcases from these monsters.
