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.

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.

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 27d7940631 minor: cosmetic, indentation 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)

Do some include shuffling for `**.h` files within lib, programs, tests, and zlibWrapper.
`lib/legacy` and `lib/deprecated` are untouched.
`#include`s within `extern "C"` blocks in .cpp files are untouched.

todo: shuffling for `xxhash.h`

Adenilson Cavalcanti 6dbd49bcd0 [riscv] Enable support for weak symbols 
Both gcc and clang support weak symbols on RISC-V, therefore
let's enable it.

Adenilson Cavalcanti c3c28c4d5a [zstd][android] Fix build with NDK r27 
The NDK cross compiler declares the target as __linux (which is
not technically incorrect), which triggers the enablement of _GNU_SOURCE
in the newly added code that requires the presence of qsort_r() used
in the COVER dictionary code.

Even though the NDK uses llvm/libc, it doesn't declare qsort_r()
in the stdlib.h header.

The build fix is to only activate the _GNU_SOURCE macro if the OS is
*not* Android, as then we will fallback to the C90 compliant code.

This patch should solve the reported issue number #4103.
