Here we give the list of the main changes introduced in Simdlib for ViSP
- 2023.09.12 (see PR #1230)
- Fix compatibility with Debian GNU/Hurd defining PATH_MAX macro
- 2022.10.19: (see PR #1108)
- Update Simd lib using https://github.com/ermig1979/Simd
revision b39197e00a902cbbc5ad397de92f086be994549b
- 2022.01.18: (see PR #990)
- Fix memory leak in BgraToRGBa conversion
Modified files:
3rdparty/simdlib/Simd/SimdAvx2BgraToBgr.cpp (search "Modif FS Fix memleak")
3rdparty/simdlib/Simd/SimdSse41BgraToBgr.cpp (search "Modif FS Fix memleak")
- Introduce avx2 support in SimdBgraToBgr()
Modified files:
3rdparty/simdlib/Simd/SimdLib.cpp
- Remove CpuSocketNumber() and CpuCoreNumber() that are using lscpu that doesn't exist on macOS
When examples are run on macOS they produce extra printings like:
```
$ ./tutorial-ibvs-4pts-plotter
sh: lscpu: command not found
sh: lscpu: command not found
sh: lscpu: command not found
sh: lscpu: command not found
```
One solution is to modify `CpuCoreNumber()` to detect macOS and run
`sysctl -a | grep machdep.cpu.thread_count | grep -o -E '[0-9]+'`
instead of
`lscpu -b -p=Core | grep -v '^#' | sort -u | wc -l"`.
But then how to modify `CpuSocketNumber()`?
Theses functions could be removed since they also introduce a non significant time when
launching a binary.
Modified files:
3rdparty/simdlib/Simd/SimdBaseCpu.cpp
3rdparty/simdlib/Simd/SimdCpu.h
to remove all reference to
CpuSocketNumber()
CpuCoreNumber(
AlgCacheL2()
AlgCacheL3()
SOCKET_NUMBER
CORE_NUMBER
L2_CACHE_SIZE
L3_CACHE_SIZE
- 2022.01.13: Fix compat with iOS (see PR #983)

3rdparty/simdlib/Simd/SimdBaseCpu.cpp
3rdparty/simdlib/Simd/SimdNeonCpu.cpp
...
- 2022.01.12: Update Simd to v4.9.109 (see PR #982)
See PR #982
- 2021.02.16: Fix compat with UWP
Modified files:
3rdparty/simdli/CMakeLists.txt
- 2020.12.07: introduce BgraToRgba conversion optimized for Avx2, Ssse3, Neon (see PR #862)
