I don't think it's that simple. "who owns the code" is not always clear.
There's often a question of who that is. That's why if somebody HAS

Hello,
The current set of plug-in events does not appear to include extension
points at the parser level.
I think it may be useful to allow plug-ins to process, e.g., #pragmas.
That would allow directives à la OpenMP to be added/extended, which is
an increasingly popular way to augment C and othe

I suppose it could, but it isn't. Instead of asking the backend for

According to the internal manual, insn length attribute can be used to
to calculate the length of emitted code chunks when verifying branch
distances.
Can it be used in code size optimization?
I may change TARGET_RTX_COSTS in my gcc port and return costs
regarding the ins lengths. I can see code s
GCC just literally emits the string in your asm expression together with other
assembly code generated by compiler. Only in next step assembler is invoked by
GCC driver.
Typically, hard register number is not used so that GCC can do register
allocation
for inline assembly.
