Bug ID: 94180
Summary: inconsistent operand constraints: "+X"
Product: gcc
Version: 9.2.0
Status: UNCONFIRMED
Keywords: rejects-valid
Severity: normal
Priority: P3
Component: inline-asm
Assignee: unassigned at gcc dot gnu.org
Reporter: frederic.recoules@univ-grenoble-alpes.fr
Target Milestone: ---
Consider the following code snippet:
int main (int argc, char *argv[])
{
int k = 0;
asm ("" : "+X" (k));
return k;
}
It produces the following error:
<source>: In function 'main':
<source>:17:5: error: inconsistent operand constraints in an 'asm'
17 | asm ("" : "+X" (k));
