Bug ID: 102836
Summary: gcc.target/i386/pieces-memset-1.c etc. FAIL
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
CC: hjl.tools at gmail dot com
Target Milestone: ---
Target: i?86-pc-solaris2.11, x86_64-pc-solaris2.11
Some gcc.target/i386/pieces-memset-*.c tests have been FAILing on 32-bit
Solaris/x86
since they were installed:
FAIL: gcc.target/i386/pieces-memset-1.c scan-assembler-not %[re]bp
FAIL: gcc.target/i386/pieces-memset-4.c scan-assembler-not %[re]bp
FAIL: gcc.target/i386/pieces-memset-41.c scan-assembler-not %[re]bp
FAIL: gcc.target/i386/pieces-memset-7.c scan-assembler-not %[re]bp
FAIL: gcc.target/i386/pieces-memset-8.c scan-assembler-not %[re]bp
It turns out that this happens because 32-bit Solaris/x86 only guarantees
4-byte stack alignment following the i386 psABI, so defaults to -mstackrealign.
Adding -mno-stackrealign to one test lets the output match what I get on
Linux/x86. I suspect that's the best option?
