In g_typeadjust, before we apply the integral promotions, we check if both types are unsigned char. If so, we promote to unsigned int, rather than int, which would be chosen by the standard rules. This is only a performance optimization and does not affect correctness, as the flags returned by g_typeadjust are only used for code generation, and not to determine types of other expressions containing this one. All unsigned char bit-patterns are valid as both int and unsigned int and represent the same value, so either signed or unsigned int operations can be used. This special case part is not duplicated by ArithmeticConvert. Partial fix for #1308. |

This directory contains test code for automatic regression testing of the CC65
compiler.
/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.
/ref - These tests produce output that must be compared with reference output.
/err - contains tests that MUST NOT compile
/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!
/asm - contains the assembler regression tests
/dasm - contains the disassembler regression tests
/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
