This fails on i686-linux:
FAIL: gcc.target/i386/attributes-error.c (test for errors, line 12)
FAIL: gcc.target/i386/attributes-error.c (test for excess errors)

Perhaps at least add
/* { dg-options "" } */
to avoid -pedantic, or
/* { dg-options "-msse2" } */
But neither of that helps with the line 12 case,
void foo8(int i, int j) __attribute__((sseregparm, fastcall)); /* { dg-error
"not compatible" } */
That is simply not diagnosed.
