*-check.h under gcc.target/i386 follows the style of main() + the ISA runtime
guard,.i.e
Int
Main (void)
{
#ifdef CHECK_CPU_SUPPORTS
If (CHECK_CPU_SUPPORTS)
#endif
do_test ();
return 0;
}
Could you follow the original conversion? Move main from those .c files into
the check.h and define those .c as options + #define + include?
And should we fflsuh(stdout) before abort () or use fprintf instead printf
since the buffer in printf may be throw way when aborted.
