            Bug ID: 98209
           Summary: printf failed with O1 or above
           Product: gcc
           Version: 9.3.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jamesgua at ca dot ibm.com
  Target Milestone: ---

Testing file:

#include <stdio.h>

int main(int argc, char** argv) __attribute__ ((__target__ ("no-sse,no-mmx"=
)));=20
int main(int argc, char** argv)
{
        printf("hello!\n");
        return 0;
}=20

cmd to compile: gcc -O3 -c test.c
On Ubuntu 20.04 (gcc version 9.3.0 (Ubuntu 9.3.0-17ubuntu1~20.04)) it failed
with "inlining failed in call to always_inline printf=E2=80=99: target spec=
ific option
mismatch" but it works on Ubuntu 16.04 (gcc version 5.4.0 20160609 (Ubuntu
5.4.0-6ubuntu1~16.04.12))

If not supported pls let me know.=
