[Tinycc-devel] arm-asm: Test script

[Danny Milosavljevic]

Updated test script for all of this (should I also commit this?  Where?):

#!/bin/sh

set -e
cd ~/src/tinycc-upstream/tinycc

cat arm-tok.h |grep DEF_ASM_CONDED |grep -v '#define' |grep -v '/[*]' |sed -e 
's;DEF_ASM_CONDED.\(.*\).$;\1;'| grep -v 'not useful' >L
total_count=0

# Note: "{r3}" is definitely different--but would complicate the assembler.

for s in $(cat L)
do
