From 37a9c3a53e3705c5120506e457455642702845e6 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Tue, 5 Jan 2021 01:26:21 -0500 Subject: [PATCH] sim: testsuite: allow tests to declare expected exit status Some tests want to verify they can control the exit status, and allowing any non-zero value would allow tests to silently fail: if it crashed & exited 1, or forced all non-zero to 1, then we wouldn't be able to differentiate with a test exiting with a status like 47. Extend the test harness to allow tests to declare their expected exit status that would be defined as a "pass". This requires a small tweak to the sim_run API to return the status directly, but that shouldn't be a big deal as it's only used by sim code. --- sim/testsuite/ChangeLog | 6 ++++++ sim/testsuite/lib/sim-defs.exp | 23 +++++++++++---------- sim/testsuite/sim/cris/ChangeLog | 7 +++++++ sim/testsuite/sim/cris/c/c.exp | 7 ++++++- sim/testsuite/sim/cris/hw/rv-n-cris/rvc.exp | 2 +- 5 files changed, 32 insertions(+), 13 deletions(-) diff --git a/sim/testsuite/ChangeLog b/sim/testsuite/ChangeLog index a32672a46be..1245ab46086 100644 --- a/sim/testsuite/ChangeLog +++ b/sim/testsuite/ChangeLog @@ -1,3 +1,9 @@ +2021-01-15 Mike Frysinger + + * lib/sim-defs.exp (sim_run): Delete status and return return_code. + (run_sim_test): Define status option.
