| | | | | | | | new method `uncompressed_update` allows to insert blocks without compression into the lz4 stream. The usage is documented in the frameCompress example Signed-off-by: Alexander Mohr <alexander.m.mohr@mercedes-benz.com>

| * | | meson: simplify version lookup and avoid deprecation warningsEli Schwartz2021-12-141-7/+2
| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | run_command() in development versions of meson will warn when the `check: ` kwarg is not specified. At the same time, lz4 has some gnarly code to manually check the return code and raise an error if it failed. Kill two birds with one stone, by making run_command inherently raise a fatal error when erroring out, then proceeding in the knowledge that it must have succeeded.

| * | Disable _tzcnt_u64 for ARM64ECBen Niu2022-01-271-1/+1
|/ / | | | | The ARM64EC is a new Microsoft-designed ARM64 ABI that is compatible with AMD64 code. However, not all AMD64 intrinsic functions are supported. For, intrinsics that are lowered to AVX, AVX2 and AVX512 instructions are not supported, including the _tzcnt_u64. To make sure this file compiles for ARM64EC, the use of _tzcnt_u64 should be neutered.
