The GCC documentation of course.  If all else fails, the GCC source
code.

In your problem 1), e.g., I would strongly suspect you got the "g"
constraint wrong there, but only a look into the GCC docs will tell.

Even it were a limitation, it's not a very important one.  No extended
asm block should ever be large enough to need non-numeric labels and
local references to those.  If it ever gets that large, it definitely
had better be in a separate, assembly-only source file, as a function.
