tests/lint: remove .exp files, as they have become redundant Now that each lint1 test lists all generated diagnostics as 'expect' comments, the information from the .exp files is no longer needed. The only information that gets lost is the order of the diagnostics, which is mostly relevant for paired messages like 'inconsistent definition' + 'previous definition was here'.

lint: concatenate string literals from left to right Previously, the string literals "1" "2" "3" "4" were concatenated in the order "23", "234", "1234". This influenced the location of the diagnostics for traditional C (which doesn't know concatenation at all) and for mixing regular strings and wide strings. Now the diagnostics occur exactly where they are expected. The first string literal defines whether the whole string is regular or wide, and any further string literals must match it. In traditional C mode, there are more diagnostics than before, but that doesn't hurt since they are still correct and nobody uses lint in traditional C mode anyway.

tests/lint: test where exactly lint complains about concatenation This only applies to traditional C and ensures that the behavior is preserved when rearranging the C parser to evaluate string concatenation from left to right.

lint: only define GCC builtins if -g is given This removes 7 wrong warnings when running lint in -t mode. Surprisingly, this added a warning that had not been there before in msg_189.c. This is because check_variable_usage skips the checks when an error occurred before. All diagnostics that happened were warnings, but the -w option treats them as errors, see vwarning.

lint: demonstrate that -t mode is practically unusable Since main1.c from 2014-04-18, running lint in -t mode produces strange warnings in lines 1 to 3 of no file at all. This is caused by the builtins that are parsed in main(). These builtins are incompatible with traditional mode because they use long double, which had not been known at that time.
Revision 1.1 / (download) - annotate - [select for diffs], Sat Jan 2 10:22:44 2021 UTC (2 years, 1 month ago) by rillig
lint: add a test for each message produced by lint1 Having a test for each message ensures that upcoming refactorings don't break the basic functionality. Adding the tests will also discover previously unknown bugs in lint. The tests ensure that every lint message can actually be triggered, and they demonstrate how to do so. Having a separate file for each test leaves enough space for documenting historical anecdotes, rationale or edge cases, keeping them away from the source code. The interesting details of this commit are in Makefile and t_integration.sh. All other files are just auto-generated. When running the tests as part of ATF, they are packed together as a single test case. Conceptually, it would have been better to have each test as a separate test case, but ATF quickly becomes very slow as soon as a test program defines too many test cases, and 50 is already too many. The time complexity is O(n^2), not O(n) as one would expect. It's the same problem as in tests/usr.bin/make, which has over 300 test cases as well.
