Thomas: as you were last fiddling with arm, you might want to check
if the test works on it.  The other alloca testcase is #ifdef'ed on

supported on arm, which I can't believe.  If that really is the case
callsave_test() needs to be conditional too.

Some time ago I posted an alloca version for ARM:

Ah, I see.  Well, alloca is highly desirable to have IMHO, so ...

but we don't build a libtcc1 for ARM

... I think we should do so then. As it seems the various arithmetic routines of libtcc1.c aren't needed on arm it would only contain alloca. I'd vote for the assembler implementation (don't know if it would have to differ between the eabi and oldabi variants).
