cdab59af76 [NFC] Simplify build by removing inl files. (#139) 2020-10-13 13:05:04 +02:00
9a8f04b24c [NFC] Generate separate tables via macro (#137)
This is a non functional change, it allows:
 - Getting rid of `unix_features_aggregator`
 - Have a single blob describing the features
 - Fix wrong mocking of `hwcaps`

Downside: abuse of macros makes the code slightly magical and harder to understand.
It think it's still an improvement over the current situation as there's less repetition and less chances to get something wrong.

4795373db2 Fix SSE detection on non-AVX CPUs (#135)
Fixes #4. This is based on #115 with a few modifications:
 - Removed use of __builtin_cpu_supports since it relies on cpuid and doesn't improve on the current situation,
 - Added detection for all of sse, sse2, sse3, ssse3, sse4_1 and sse4_2,
 - Added tests for Atom, Nehalem, and P3 processors,

Thx to @gadoofou87 for providing the original PR.
It also removes the need for #92

* Fix SSE detection on non-AVX CPUs

bdb36d9489 Fix a few compile warnings (#84)
Visual C++ reported a number of warnings:

..\src\filesystem.c(27): warning C4996: '_open': This function or variable may be unsafe. Consider using _sopen_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.
..\src\filesystem.c(34): warning C4267: 'function': conversion from 'size_t' to 'unsigned int', possible loss of data

Most of them, with the exception of _open() -> _sopen_s() are about
questionable implicit casts. Fixing the types and adding explicit casts
to explicitly mark the intention (and silence the warnings in the process)
