Bug ID: 110849
Summary: [14 Regression] XPASS in gcc.dg/unroll-7.c
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: patrick at rivosinc dot com
Target Milestone: ---
New XPASS on trunk:
XPASS: gcc.dg/unroll-7.c scan-rtl-dump-not loop2_unroll "Invalid sum"
Bisected to
https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=a7d4310aed539b04345894ebafb49ca364780653
"Fix profile update after RTL unrolling"
Tested using make-report in https://github.com/riscv-collab/riscv-gnu-toolchain
with tip-of-tree gcc
Confirmed XPASS failure on:
linux rv32gc ilp32d medlow
linux rv64gc lp64d medlow
newlib rv32gc ilp32d medlow
newlib rv64gc lp64d medlow
It doesn't seem like it would be a target-specific issue, but the patch was
regtested on x86 before being committed.

I'm guessing on the component so feel free to update the report if it's not a
tree-optimization issue :)
