tests/lint: make 'expect+-' comments stricter Previously, the expectations from these comments were already satisfied if the expectation occurred somewhere in the actual message from lint. This meant that the prefix 'error:' or 'warning:' could be omitted from the 'expect' comment. These omissions were hard to see in a manual review. Now any omissions must be visually marked with '...'. The test msg_342 now reports its messages properly as being in the file msg_342.c, rather than msg_341.c. This had been a copy-and-paste mistake.

tests/lint: fix tests on platforms other than x86_64 In msg_259_ilp32.c 1.6 from 2022-04-15, I removed the option -S from the test in order to keep the message 259, but I forgot to fix the C99-style comment as well. In platform_int.c, the default lint option -S no longer generated warning 259, so remove that option.

lint: in C99 mode, do not warn about non-prototype conversions Message 259 is "argument #%d is converted from '%s' to '%s' due to prototype", and it is intended to warn about compatibility between traditional C where functions had no prototypes and standard C where functions have prototypes. Running lint in C99 mode is further away from traditional C than running lint in C90 mode, so that warning doesn't make sense for C99. There are still some inconsistencies in the 5 language version modes that lint offers: -t for traditional C (no option) for migrating traditional C to C90 -s for C90 code -S for C99 code -Ac11 for C11 code By disabling warning 259 in C99 mode, a typical NetBSD build produces 14.500 fewer warnings than before, of about 100.000 total. Message 259 overlaps with message 298 "conversion from '%s' to '%s' may lose accuracy, arg #%d", and in some cases of potentially lossy conversions, lint now produces none of these messages. In some other cases, these warnings were reported redundantly. The cases where message 298 makes sense will be added back later, as needed.

tests/lint: add cross-references to message 297 The check for lossy integer conversions is already implemented, it's just not activated in the default NetBSD build.

tests/lint: guard against typos in test environment configuration Some tests had "lint1-only-if" without a trailing colon, others included the trailing colon. The tests that included the trailing colon were run even though they were supposed to be skipped, and they failed, as could be expected. To prevent further typos, always require the trailing colon, just as in "lint1-flags" and fail fast on unknown "lint1" comments.

tests/lint: add test that only runs where char == unsigned char There a 4 regular NetBSD builds where lint is activated. All these builds run on platforms where char == signed char. The official test runs from https://releng.netbsd.org/test-results.html mostly have char == signed char as well. However, lint behaves differently on platforms with char == unsigned char. On these platforms, a simple "char ch = '\xff'" leads to the bogus warning that "conversion of 'int' to 'char' is out of range".

tests/lint: add tests for ILP32 platforms Previously, all tests for lint had to produce the exact same output, no matter which platform they ran on. This differs from practical needs since lint is intended to produce different results depending on whether the platform is ILP32 or LP64. Examples for these are type conversions and the widths of the integer types during lexical analysis.
