Bump gcc into 14.2 release version. #1531

Bump gcc into 14.2.0 release version, update the allowlist.

TommyMurphyTM1234 · 2024-08-12T15:41:11Z

I guess that this PR renders the following one moot/redundant?

Bump GCC to 14[.1.0] - addresses #1471 #1472

IIRC it's a random fail case?

I will check it again :)

Reproduced the fail case, move it into glibc.rv64.log.

It also appeared in https://github.com/riscv-collab/riscv-gnu-toolchain/actions/runs/10380519463/job/28740484185?pr=1531
Move it into glibc.log .

Ooops, could you point me which commit fix that? so that I could backport that and we will have fix on 14.3...

I think it is https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=b1520d2260c5e0cfcd7a4354fab70f66e2912ff2,
I compared the trunk https://gcc.gnu.org/git/?p=gcc.git&a=search&h=HEAD&st=commit&s=full-vec-move1.c
with the gcc14.2 release tree https://gcc.gnu.org/git/?p=gcc.git&a=search&h=04696df09633baf97cdbbdd6e9929b9d472161d3&st=commit&s=full-vec-move1.c

ack, I am running regression on my machine.

cmuellner

Thanks for working on this!

cmuellner · 2024-08-26T14:22:45Z

I'm running a multilib build locally right now (with this PR on top of the other update PRs for binutils, qemu, glibc, and gdb).
If everything runs fine, I will merge this later today.

It seems because lack of floating point support, this won't generate any FMA after you adding "-march=rv32imac -mabi=ilp32"
