Bug ID: 122956
Summary: [GCC16 regression] ICE caused by r16-4000 when
building LLVM14 with -Ofast -flto=auto
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: ipa
Assignee: unassigned at gcc dot gnu.org
Reporter: liuhongt at gcc dot gnu.org
Target Milestone: ---
When building a private llvm based on LLVM14, GCC16 issued an ICE as below,
it's difficult to exract a testcase, I've bisected it r16-4000, @honza any
ideas based on backtrace?
the option I use is -Ofast -flto=auto
