| # 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. |
