CMakeLists: match the hardening-check flag detection that passed CI

Restore the implementation from the earlier passing revision: query hardening-check --help with ERROR_QUIET and match the advertised option names including their leading dashes. This avoids the result-code guard that could skip detection if --help exits non-zero, and avoids merging stdout/stderr into one variable.
CMakeLists: reformat hardening-check comment for cmake-format

weaselbot	2d8508b9fd	CMakeLists: use hardening-check --help output regardless of exit code The previous change tried to detect which architecture-specific skip flags the installed hardening-check binary supports by grepping its --help output, but it only used that output when the help command returned exit code 0. Some versions of hardening-check print their help to stderr and exit with a non-zero status, so the detection was skipped entirely and no arch-specific flag was passed. On arm64 this left the x86-only control-flow-integrity check un-ignored, causing the release hardening_check test to fail. Stop conditioning the flag detection on the help command's exit status and remove the now-unused result variable. Also reformat the comment to satisfy cmake-format. Fixes pre-commit and release arm64 CI failures for #51.	2026-06-22 13:44:10 -04:00
weaselbot	92b67f572f	Fix release and coverage CI failures * ConflictSet.cpp: enable the interleaved read/write path whenever musttail is available, falling back to the default calling convention when preserve_none is not supported. This prevents a large block of compiled-but-dead code from being counted in coverage. * CMakeLists.txt: detect which arch-specific hardening-check options the installed hardening-check binary supports, including the newer hyphenated spellings, so the release test no longer fails with an unknown option. * .gitea/workflows/ci.yml: build the coverage job with -DUSE_SIMD_FALLBACK=ON so AVX512-only functions that cannot execute on the CI runners are not counted against line coverage.	2026-06-22 13:44:10 -04:00
weaselbot	7eaac2a184	Make ConflictSet non-copyable in C++98/C++03 `ConflictSet(const ConflictSet&)` and `operator=(const ConflictSet&)` were only deleted for C++11 and later. In C++98/C++03 the compiler implicitly generated public copy operations, so copying a ConflictSet shared the opaque `Impl*` and caused a double-free on destruction. Declare both operations private and leave them undefined when `__cplusplus <= 199711L`, matching the standard pre-C++11 idiom for move-only types. Guard the declarations with `defined(__cplusplus)` so they are not exposed to C90 compilation units. Closes #48	2026-06-22 13:43:04 -04:00
andrew	e9c904a86b	CMakeLists.txt: don't require hardening-check --help to exit 0 hardening-check --help returns exit code 1, so the previous hardening_check_help_result EQUAL 0 guard skipped parsing the help output entirely. As a result, architecture-specific flags such as --nobranchprotection on x86_64 were never added to the test command. Parse the help output regardless of exit code; the option-string regex checks are sufficient.	2026-06-22 13:05:33 -04:00
