#! /bin/bash

# Compare the assembly language output for all the gcc tests.

#
# Invoke it as "bash compare-all-tests target1 target2 ... targetN".
# Assumptions are:
#
# 1) that the base and patched compilers reside respectively in
# base-$target-build and $target-build, where $target is the commandline
# argument to compare-all-tests, and should match the variables in the
# script itself so that the correct set of options is tested.  Both
# compilers should be fully built (including target libraries).
# 
# 2) that the testsuite has been run on the base compiler (since it's
# just compilation testing, using RUNTESTFLAGS=--target_board=basic-sim
# usually suffices).
# 
# Tests that fail to compile on the base compiler are not compared.
