@ -12,6 +12,13 @@ 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
