This directory contains test code for automatic regression testing of the CC65
|
|
compiler and tools.
|
|
|
|
/asm - contains the assembler regression tests
|
|
|
|
/dasm - contains the disassembler regression tests
|
|
|
|
|
|
/val, /ref and /err generally contain the tests that are used to verify that the
|
|
compiler is working as expected (when the tests behave as described):
|
|
|
|
/val - The bulk of tests are contained here, individual tests should exit with
|
|
an exit code of EXIT_SUCCESS when they pass, or EXIT_FAILURE on error.
|
|
|
|
/standard - like the tests in /val, the tests must exit with EXIT_SUCCESS on
|
|
success. Unlike the tests in /val these are not compiled for every
|
|
combination of optimizer options, but instead always with -Osir and then
|
|
for each supported C-standard (C89, C99, CC65). The goal is to use these
|
|
to check for regressions in standard conformance of the compiler and the
|
|
library.
|
|
|
|
/ref - These tests produce output that must be compared with reference output.
|
|
|
|
/err - contains tests that MUST NOT compile
|
|
|
|
|
|
/todo and /misc generally contain the tests that fail because of known bugs:
|
|
|
|
/todo - These tests fail due to open compiler issues.
|
|
|
|
The makefile in this directory _expects_ the tests to fail, because of
|
|
that when an issue was fixed it will break the CI. The test should get
|
|
moved to /val in the PR fixing the issue, which will make CI pass again.
|
|
No changes to makefiles are required!
|
|
|
|
|
|
/misc - a few tests that need special care of some sort
|
|
|
|
Tests that (incorrectly) fail to compile and other tests that fail and
|
|
do NOT return an exit code are collected here. The makefile _expects_
|
|
those tests to fail, so when an issue is fixed it will break the CI.
|
|
When this happens, the PR fixing the issue should also "invert" the
|
|
failing condition in the makefile by adding a $(NOT) before the
|
|
offending line (or removing it when it is already there), which will
|
|
make the CI pass again. The test should then be moved elsewhere later,
|
|
which will require additional changes to the makefile(s).
|
|
|
|
|
|
To run the tests use "make" in this (top) directory, the makefile should exit
|
|
with no error.
|
|
|
|
When a test failed you can use "make continue" to run further tests.

TODO:
|
|
|
|
- reduce usage of "common.h" to a minimum
|
|
- convert more tests from using reference output to returning an exit code
