https://gcc.gnu.org/bugzilla/show_bug.cgi?id=113089
Bug ID: 113089
Summary: [14 Regression][aarch64] ICE in
process_uses_of_deleted_def, at rtl-ssa/changes.cc:252
since r14-6605-gc0911c6b357ba9
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: hliu at amperecomputing dot com
Target Milestone: ---
SPEC2017 525.x264 build failure. Options are: -O3 -mcpu=neoverse-n1
-funroll-loops -flto=32 --param early-inlining-insns=96 --param
max-inline-insns-auto=64 --param inline-unit-growth=96
The failure happens while doing LTO optimization:
gcc -std=c99 ... -o ldecod_r
during RTL pass: ldp_fusion
ldecod_src/intra_chroma_pred.c: In function 'intrapred_chroma':
ldecod_src/intra_chroma_pred.c:420:1: internal compiler error: in
