--- Comment #3 from Dominik Vogt <vogt at linux dot vnet.ibm.com> --- Sorry, the expample with t2() in the code snippet above should have the pragmas in the opposite order: -- snip -- #pragma GCC target ("no-sse") #pragma GCC target ("fpmath=sse") void t2(void) { } -- snip -- The attached files ar all right, though.
