[Bug inline-asm/30527] Use of input/output operands in __asm__ templates not fully documented
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=30527 David changed: What|Removed |Added CC||gccbugzilla@limegreensocks. ||com --- Comment #5 from David --- These modifiers are intended primarily for use by Machine Descriptions. As a result, some of them aren't going to be meaningful/usable by inline asm code. And it makes sense to leave open the option to change their meaning should future MD work require it, something that documenting them all would prevent. On the other hand, some of these values are indeed quite useful for inline asm. The compromise, as evidenced by 6.43.2.7 (added in v5.x), is to document certain commonly needed/used modifiers (such as the %k0 referenced above). If there is some additional modifier that you need, I'd recommend opening a new bug and making an explicit case for it. In the meantime, I recommend closing this bug (as fixed).

--- Comment #2 from pinskia at gcc dot gnu dot org 2007-01-21 16:37 --- Every target have slightly different operand modifiers. They are usually "documented" in config/*/*.md or config/*/*.c, but I think it is incorrect to documented them for real because people will then abuse them. -- pinskia at gcc dot gnu dot org changed: What|Removed |Added Component|c |inline-asm Keywords||documentation http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30527

--- Comment #3 from davmac at davmac dot org 2007-01-22 04:17 --- You've got to be kidding - these things are genuinely useful. What sort of abuse are you worried about? In any case, I'd like to know if that is the general consensus among maintainers. I'm not going to write documentation and submit a patch if it's not going to be accepted. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30527

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=30527 --- Comment #4 from Davin McCall --- I recently stumbled across section 6.43.2.7 of the manual, which does in fact document the operand modifiers for (and only for) x86. Modifiers for other architectures are not documented.
