[Openmcl-devel] x86-32 inline assembly possible?

No, there isn't.

A long time ago (in 68K MCL), there was something called LAP-INLINE.
A short explanation of why it was removed is that using it implicitly
depended on lots of compiler details; when those details changed,
code that used LAP-INLINE broke.

GCC addresses this problem by using a fairly rich interface-definition
language to describe the effects and dependencies of a block of inline
assembler.  (In some GCC versions, that language looks a lot like line
noise ...)  Rather than introduce something similar, we just dropped

Matt's idea (user-definable "virtual instructions" (vinsns)) might
be a way to reintroduce some of this functionality, though there'd
be some issues to resolve there.
