Summary: Solaris i386 - some GCC tests fails with: internal
compiler error: Illegal Instruction
Product: gcc
Version: 11.5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: sumbera at volny dot cz
Target Milestone: ---
While updating from GCC 11.4 to 11.5 I see quite a few internal compiler
errors.
I see this just on i386 (SPARC is fine):
Example from x86_64-pc-solaris2.11/libgomp/testsuite/libgomp.log:
