x86: Pass -mno-80387 to compile pr121208-1(a|b).c
Pass -mno-80387 to compile pr121208-1(a|b).c to silence
.../pr121208-1a.c:11:1: sorry, unimplemented: 80387 instructions aren’t
allowed in a function with the ‘no_caller_saved_registers’ attribute
Partially backport the PR target/121540 fix
9d7f45e9806 x86: Disallow MMX and 80387 in no_caller_saved_registers
function
to also add -mno-sse -mno-mmx.
PR target/121208
* gcc.target/i386/pr121208-1a.c (dg-options): Add
-mno-sse -mno-mmx -mno-80387.
* gcc.target/i386/pr121208-1b.c (dg-options): Likewise.
