Curiously this tests runs with `-O2 -mavx -mfpmath=sse` for me locally which passes but I can reproduce it using the reported flags. > Any news of anything faster would be appreciated. You don't have to rebuild the whole thing at every step just the C compiler since this is a C test. So once you build it once you can go into the build dir (since you're doing a non-bootstrap build) and do `make cc1 -C gcc -j <num>` . Which should take just seconds. If you're doing a bootstrapped build you should just build the last stage. You can then run the testcase using the `xgcc` command you see in the log (you don't need the install). ^ permalink raw reply [flat|nested] 13+ messages in thread
