Hi.
Opening per suggestion in Bug 23200.
Not entirely sure if this is really a bug,
but it looks like the one.
The following program:
---
static char var;
int main()
{
asm volatile ("" :: "i"(&var));
return 0;
}
---
gives this when compiled with -fpic -m32:
---
asvar1.c: In function 'main':
asvar1.c:4: warning: asm operand 0 probably doesn't match constraints
asvar1.c:4: error: impossible constraint in 'asm'
---
Without -m32 it compiles.
On what targets the relocations are supported?
