# 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.
