- The build macro `ZSTD_NO_INTRINSICS` can be defined to disable all explicit intrinsics.
Compiler builtins are still used.
- The build macro `ZSTD_DECODER_INTERNAL_BUFFER` can be set to control
the amount of extra memory used during decompression to store literals.
This defaults to 64kB. Reducing this value reduces the memory footprint of
`ZSTD_DCtx` decompression contexts,
but might also result in a small decompression speed cost.
- The C compiler macros `ZSTDLIB_VISIBLE`, `ZSTDERRORLIB_VISIBLE` and `ZDICTLIB_VISIBLE`
can be overridden to control the visibility of zstd's API. Additionally,
`ZSTDLIB_STATIC_API` and `ZDICTLIB_STATIC_API` can be overridden to control the visibility
of zstd's static API. Specifically, it can be set to `ZSTDLIB_HIDDEN` to hide the symbols
from the shared library. These macros default to `ZSTDLIB_VISIBILITY`,
`ZSTDERRORLIB_VSIBILITY`, and `ZDICTLIB_VISIBILITY` if unset, for backwards compatibility
with the old macro names.
