The libtcc1 for ARM on my homepage (which got linked in several older
mails to the list) included an alloca right from the beginning.
But the ARM EABI version needs an alloca that aligns to 8 bytes instead
of 4. Here it is:
alloca:
sub r0,sp,r0
bic r0,r0,#7
mov sp,r0
mov pc,lr
This one is actually 4 bytes shorter than the one on my homepage :-)
