Bug ID: 94095
Summary: Modifier 'a' do not work as described
Product: gcc
Version: unknown
Status: UNCONFIRMED
Keywords: documentation
Severity: normal
Priority: P3
Component: inline-asm
Assignee: unassigned at gcc dot gnu.org
Reporter: frederic.recou...@univ-grenoble-alpes.fr
Target Milestone: ---
In https://gcc.gnu.org/onlinedocs/gcc/Extended-Asm.html 6.47.2.8, it is said
that 'a' "Print an absolute memory reference" (aka *%eax for 'att') but
experiments shows that it actually print '(%eax)'.
But yet, what is the intended behavior?
Is it actually valid to use 'a' modifier with 'p' constraint in
void *x = NULL;
__asm__ ("leal %a1, %0" : "=r" (x) : "p" (&x));
?
