            Bug ID: 94118
           Summary: Undocumented inline assembly [target] operand
                    modifiers
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Keywords: documentation
          Severity: normal
          Priority: P3
         Component: web
          Assignee: unassigned at gcc dot gnu.org
          Reporter: frederic.recoules@univ-grenoble-alpes.fr
  Target Milestone: ---

The section 6.47.2.8 x86 Operand Modifiers of
https://gcc.gnu.org/onlinedocs/gcc/Extended-Asm.html is only about x86.

As it was done for Operand Constraints
(https://gcc.gnu.org/onlinedocs/gcc/Machine-Constraints.html#Machine-Constraints)
it would be beneficial to create a separated page.

Moreover, the common constraints 'a' (print address) and 'n' are currently not
documented.
