7# Invoke it as "bash compare-all-tests target1 target2 ... targetN".
8# Assumptions are:
9#
10# 1) that the base and patched compilers reside respectively in
11# base-$target-build and $target-build, where $target is the commandline
12# argument to compare-all-tests, and should match the variables in the
13# script itself so that the correct set of options is tested.  Both
14# compilers should be fully built (including target libraries).
15# 
16# 2) that the testsuite has been run on the base compiler (since it's
17# just compilation testing, using RUNTESTFLAGS=--target_board=basic-sim
18# usually suffices).
19# 
20# Tests that fail to compile on the base compiler are not compared.
