I suppose inline ASM should be no problem with the GNU compile
infrastructure. With the typical "embedded" cross compiling, all high
language code is compiled to their ASM dialect and converted to binary
by AS.
Inline ASM just bypasses the high language to ASM step (i.e. replaces it
by a very simple "compiler" that handles labels like "1:" (accesses by a
notation like "1f" or "1b") and some % - notation for accessing registers.
Of course th GNU inline assembler syntax is completely different (and
very versatile and rather hard to understand in detail -> in/out
parameters, "clobbers", memory barriers...) than the ASM inline syntax
used in fpc.
