Hi! In our distro builds, we test with RUNTESTFLAGS='--target_board=unix\{,-fstack-protector-strong\}' because SSP is something we use widely in the distribution. 4 new strub test FAIL with that option though, as can be seen with a simple make check-gcc check-g++ RUNTESTFLAGS='--target_board=unix\{,-fstack-protector-strong\} dg.exp=strub-O*' - in particular, the expand dump \[(\]call\[^\n\]*strub_leave.*\n\[(\]code_label regexps see code_labels in there introduced for stack protector.
The following patch fixes it by using -fno-stack-protector for these explicitly. Tested on x86_64-linux, ok for trunk? 2023-12-11 Jakub Jelinek <ja...@redhat.com> * c-c++-common/strub-O2fni.c: Add -fno-stack-protector to dg-options. * c-c++-common/strub-O3fni.c: Likewise. * c-c++-common/strub-Os.c: Likewise. * c-c++-common/strub-Og.c: Likewise. --- gcc/testsuite/c-c++-common/strub-O2fni.c.jj 2023-12-08 08:28:23.689170380 +0100 +++ gcc/testsuite/c-c++-common/strub-O2fni.c 2023-12-11 09:25:49.100792709 +0100 @@ -1,5 +1,5 @@ /* { dg-do compile } */ -/* { dg-options "-O2 -fstrub=strict -fdump-rtl-expand -fno-inline" } */ +/* { dg-options "-O2 -fstrub=strict -fdump-rtl-expand -fno-inline -fno-stack-protector" } */ /* { dg-require-effective-target strub } */ /* With -fno-inline, none of the strub builtins are inlined. */ --- gcc/testsuite/c-c++-common/strub-O3fni.c.jj 2023-12-08 08:28:23.707170125 +0100 +++ gcc/testsuite/c-c++-common/strub-O3fni.c 2023-12-11 09:25:56.388695362 +0100 @@ -1,5 +1,5 @@ /* { dg-do compile } */ -/* { dg-options "-O3 -fstrub=strict -fdump-rtl-expand -fno-inline" } */ +/* { dg-options "-O3 -fstrub=strict -fdump-rtl-expand -fno-inline -fno-stack-protector" } */ /* { dg-require-effective-target strub } */ /* With -fno-inline, none of the strub builtins are inlined. */ --- gcc/testsuite/c-c++-common/strub-Os.c.jj 2023-12-08 08:28:23.707170125 +0100 +++ gcc/testsuite/c-c++-common/strub-Os.c 2023-12-11 09:26:24.994313267 +0100 @@ -1,5 +1,5 @@ /* { dg-do compile } */ -/* { dg-options "-Os -fstrub=strict -fdump-rtl-expand" } */ +/* { dg-options "-Os -fstrub=strict -fdump-rtl-expand -fno-stack-protector" } */ /* { dg-require-effective-target strub } */ /* At -Os, without -fno-inline, we fully expand enter, and also update.
