Yann Collet c7cd7dc04b better MT fluidity 
--patch-from no longer blocked on first job dictionary loading
 2025-02-05 18:42:00 -08:00
Yann Collet f11bd19c7f ensure cdict is properly reset to NULL 2025-02-05 18:42:00 -08:00
Yann Collet 7406d2b6eb skips the need to create a temporary cdict for --patch-from 
thus saving a bit of memory and a little bit of cpu time
 2025-02-05 18:42:00 -08:00
Yann Collet 220abe6da8 reduced memory usage 
by avoiding to duplicate in memory
a dictionary that was passed by reference.

Yann Collet e117d79e22 fix minor alignment warning 2025-02-05 16:13:58 -08:00
Yann Collet c39424ea87 fix minor alignment warning 
this is a prototype definition error:
`_mm_storeu_si128()` should accept a `void*` pointer,
since it explicitly states that it accepts unaligned addresses
yet requiring a `__m128i*` tells otherwise, and requires the compiler the enforce this alignment.
 2025-02-05 16:11:54 -08:00
Yann Collet 32dff04d32 fix one minor alignment warning 
seems like a prototype interface error:
input parameter should have been `const void*`,
since the documentation is explicit that input doesn't have to be aligned,
but `const __m256i*` makes the compiler enforce it.
 2025-02-05 15:46:44 -08:00
Yann Collet 54e9d46db4 added __clang__ to compiler-specific alignment attribute 
when clang is used within msvc, `__GNUC__` isn't defined,
so testing `__clang__` explicitly is required.
 2025-02-05 13:48:24 -08:00
Yann Collet bcf404c0ab changed C11 keyword to _Alignas 
so that it doesn't depend on #include

Yann ColletandGitHub 48b186f76b Merge pull request #4253 from facebook/BitContainerType 
minor: use BitContainerType when appropriate
 2025-01-19 18:35:36 -08:00
Yann Collet 82346b92bb minor: generalize BitContainerType 
technically equivalent to `size_t`,
but it's the proper type for underlying register representation.

This makes it possible to control register type, and therefore size, independently from `size_t`,
which can be useful on systems where `size_t` is 32-bit, while the architecture supports 64-bit registers.
 2025-01-19 18:05:57 -08:00
Yann Collet 4bbf4a285d enable DYNAMIC_BMI2 by default on x86 (32-bit mode) 
so far was only enabled for x64 (64-bit mode)
 2025-01-19 08:11:59 -08:00
Yann Collet a556559841 no longer limit automated BMI2 detection to x64 
this was previously no triggered in x86 32-bit mode,
due to a limitation in `bitstream.h`, that was fixed in #4248.

Now, `bmi2` will be automatically detected and triggered
at compilation time, if the corresponding instruction set is enabled,
even in 32-bit mode.

Also: updated library documentation, to feature STATIC_BMI2 build variable

Yann Collet f0b5f65bca fixed minor static function declaration issue 
in AVX2 mode only
 2025-01-18 22:49:16 -08:00
Yann Collet 9efb09749b added a CI test for x86 32-bit + avx2 combination 
which is expected to be quite rare, but nonetheless possible.

This test is initially expected to fail, before integration of #4248 fix

Pavel P ee17f4c6d2 Use _bzhi_u32 for 32-bit builds when building with STATIC_BMI2 
`_bzhi_u64` is available only for 64-bit builds, while `BIT_getLowerBits` expects `nbBits` to be less than `BIT_MASK_SIZE` (`BIT_MASK_SIZE` is 32)
