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 1ac79ba1b6 minor: simplify ZSTD_selectSequenceCopier 2024-12-20 10:36:56 -08:00
Yann Collet 894ea31281 codemod: ZSTD_sequenceCopier -> ZSTD_SequenceCopier_f 2024-12-20 10:36:56 -08:00
Yann Collet c97522f7fb codemod: ZSTD_sequenceFormat_e -> ZSTD_SequenceFormat_e 
since it's a type name.

Note: in contrast with previous names, this one is on the Public API side.
So there is a #define, so that existing programs using ZSTD_sequenceFormat_e still work.
 2024-12-20 10:36:56 -08:00

Yann Collet a2245721ca codemod: seqStore_t -> SeqStore_t 
same idea, SeqStore_t is a type name, it should start with a Capital letter.
 2024-12-20 10:36:55 -08:00
Yann Collet 9671813375 codemod: seqDef -> SeqDef 
SeqDef is a type name, so it should start with a Capital letter.
