Sylvain,
Is this on a branch in your github repository
https://github.com/kalray/gcc
somewhere ?
That would make it easier to test it for me (and probably others).
See for instance my mail here (d.d. Thu Oct 5 14:45:05 GMT 2023):

Hi!
Sorry for the late reply; I'm still working through email accumulated
during (mostly offline) vacations after the GNU Tools Cauldron... ;-)

Hi Richard
I get it, thank you again.
And I got another problem, so I'd like ask it by the way. Can the left
shift of the induction variable in a loop be optimized as a constant?
Like the code below:
int ans = 0;
int width = rand() % 16;
for (int j = 0; j < width; j++)
ans += 1 << (j + width)
Hi Richard Biener,
Just have a try for the suggestion, remove the size check of vectorizable_call
is able to generate the .LRINT standard name
from SF to DI, with below sample code. I will run a x86 bootstrap and
regression test for this change.

test_lrintf (long *out, float *in, unsigned

Hi, I'm trying to write a pass to erase some useless functions or to
put it another way, detect whether a function is pure or not. (Of
course I know some passes can do the clean after inline)
Here is the problem I got, If a function satisfy the following points,
can it be considered safe to delete
Thanks Richard Biener, will have a try and keep you posted.
