--- Comment #12 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I said that above, -mdejagnu-cpu=power10 isn't passed to the effective target snippet compilation, so it doesn't test whether the test with -mdejagnu-cpu=power10 will be power10, but rather tests whether the compiler is configured to default to -mcpu=power10 or perhaps whether this is --target_board=unix/-mcpu=power10 testing: Executing on host: /usr/src/gcc/objp16/gcc/xgcc -B/usr/src/gcc/objp16/gcc/ -m32 -fdiagnostics-plain-output -mcpu=power10 -c -o power10_ok1793558.o power10_ok1793558.c (timeout = 300) spawn -ignore SIGHUP /usr/src/gcc/objp16/gcc/xgcc -B/usr/src/gcc/objp16/gcc/ -m32 -fdiagnostics-plain-output -mcpu=power10 -c -o power10_ok1793558.o power10_ok1793558.c Executing on host: /usr/src/gcc/objp16/gcc/xgcc -B/usr/src/gcc/objp16/gcc/ /usr/src/gcc/gcc/testsuite/gcc.target/powerpc/bswap-brw.c -m32 -fdiagnostics-plain-output -O2 -mdejagnu -cpu=power10 -ffat-lto-objects -fno-ident -S -o bswap-brw.s (timeout = 300) spawn -ignore SIGHUP /usr/src/gcc/objp16/gcc/xgcc -B/usr/src/gcc/objp16/gcc/ /usr/src/gcc/gcc/testsuite/gcc.target/powerpc/bswap-brw.c -m32 -fdiagnostics-plain-output -O2 -mdejagnu-c pu=power10 -ffat-lto-objects -fno-ident -S -o bswap-brw.s Executing on host: /usr/src/gcc/objp16/gcc/xgcc -B/usr/src/gcc/objp16/gcc/ exceptions_enabled1793558.cc -m32 -fdiagnostics-plain-output -S -o exceptions_enabled1793558.s (time out = 300) spawn -ignore SIGHUP /usr/src/gcc/objp16/gcc/xgcc -B/usr/src/gcc/objp16/gcc/ exceptions_enabled1793558.cc -m32 -fdiagnostics-plain-output -S -o exceptions_enabled1793558.s PASS: gcc.target/powerpc/bswap-brw.c (test for excess errors) PASS: gcc.target/powerpc/bswap-brw.c scan-assembler \\mbrw\\M Executing on host: /usr/src/gcc/objp16/gcc/xgcc -B/usr/src/gcc/objp16/gcc/ arch_pwr101793558.c -m32 -fdiagnostics-plain-output -S -o arch_pwr101793558.s (timeout = 300) spawn -ignore SIGHUP /usr/src/gcc/objp16/gcc/xgcc -B/usr/src/gcc/objp16/gcc/ arch_pwr101793558.c -m32 -fdiagnostics-plain-output -S -o arch_pwr101793558.s arch_pwr101793558.c:3:18: error: #error does not have power10 support. compiler exited with status 1 FAIL: gcc.target/powerpc/bswap-brw.c scan-assembler \\mxxbrw\\M
