Bug ID: 116273
Summary: [14/15 regression] RISC-V: gcc.dg/long_branch.c flakey
timeout
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: ewlu at rivosinc dot com
Target Milestone: ---
Our postcommit ci has been seeing the long_branch.c testcase flakily fail since
r14-7128-g1a51886a79c.
https://github.com/patrick-rivos/gcc-postcommit-ci/issues?page=2&q=long_branch.c
It appears to mostly affect rv32 linux/newlib targets. I'm not sure if it is
due to contention during heavy workloads.
