Summary: Random FAIL: gcc.dg/lto/save-temps
c_lto_save-temps_0.o-c_lto_save-temps_0.o link, -O
-flto -save-temps
Product: gcc
Version: 11.0

Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org

Target Milestone: ---
On Linux/x86-64 with 96 cores, I got random:
Executing on host:
/export/gnu/import/git/gcc-test-master-intel64-native/bld/gcc/xgcc
-B/export/gnu/import/git/gcc-test-master-intel64-native/bld/gcc/

/usr/local/bin/ld: i386 architecture of input file
`./gcc-dg-lto-save-temps-01.ltrans0.ltrans.o' is incompatible with i386:x64-32
output
/usr/local/bin/ld: final link failed: file in wrong format
collect2: error: ld returned 1 exit status
compiler exited with status 1
FAIL: gcc.dg/lto/save-temps c_lto_save-temps_0.o-c_lto_save-temps_0.o link, -O
-flto -save-temps
with
$ make -j 56 check RUNTESTFLAGS="--target_board='unix{-m32,-mx32,}'"
The problem is that -m32, -mx32 and -m64 use the same filename,
gcc-dg-lto-save-temps-01.ltrans0.ltrans.o.
