And here is the same thing for aarch64. Bootstrapped/regtested on aarch64-linux, ok for trunk? I think it is better not to accept any spaces in there, than accepting it only at the beginning and after , but not e.g. at the end of before , like the trunk currently does, furthermore, e.g. x86 or ppc don't allow spaces there. 2019-04-16 Jakub Jelinek <ja...@redhat.com> PR target/89093 * config/aarch64/aarch64.c (aarch64_process_one_target_attr): Don't skip whitespace at the start of target attribute string. * gcc.target/aarch64/pr89093.c: New test. * gcc.target/aarch64/pr63304_1.c: Remove space from target string. --- gcc/config/aarch64/aarch64.c.jj 2019-04-11 10:26:22.907293129 +0200 +++ gcc/config/aarch64/aarch64.c 2019-04-15 19:59:55.784226278 +0200 @@ -12536,10 +12536,6 @@ aarch64_process_one_target_attr (char *a char *str_to_check = (char *) alloca (len + 1); strcpy (str_to_check, arg_str); - /* Skip leading whitespace. */ - while (*str_to_check == ' ' || *str_to_check == '\t') - str_to_check++; - /* We have something like __attribute__ ((target ("+fp+nosimd"))).
