Z. Liu cd8ca9d92e lib/zstd.h: move pragma before static 
otherwise will cause dev-python/zstandard build failed when compiling with
clang as reported at https://bugs.gentoo.org/950259

the root cause is pycparser, which is unfixed since reported 2.5 years
ago, :(

Yann Collet a9b8fef2e8 add support for C11 Annex K qsort_s() 
standard defined re-entrant variant of qsort().
Unfortunately, Annex K is optional.

Yann Collet dcf675886b re-design qsort() selection in cover

Nick TerrellandNick Terrell 68dfd14a8c [linux] Opt out of row based match finder for the kernel 
The row based match finder is slower without SIMD. We used to detect the
presence of SIMD to set the lower bound to 17, but that breaks
determinism. Instead, specifically opt into it for the kernel, because
it is one of the rare cases that doesn't have SIMD support.

Nick TerrellandNick Terrell 190a620974 [zstd] Remove global variables in dictBuilder 
D50949782 fixed a race condition updating `g_displayLevel` by disabling display.
Instead of disabling display, delete the global variable and always "capture" a local `displayLevel` variable.
This also fixes `DISPLAYUPDATE()` by requiring the user to pass in the last update time as the first parameter.

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

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
