Raymond Knopp a7bc282302 First-level of support for new aarch64 machines 
Testing on Neoverse N1 (Ampere 3GHz). Tested only on a subset of phy-simulators.

- Changes:
- use SIMDE consistently
- adaptations of LDPC decoder generator for ARMv8 performance
- SIMDe modifications of Intel CRC to allow for aarch64 build.
  optimizations for 128-bit to improve performance of LDPC encode/decode
  on aarch64 (Neoverse 1)
- added BG2 files for 128-bit ldpc encoder (aarch64)
- testing on Xeon
- testing on x86
- minor changes to build/run on x86
- change in crc.h after returning to aarch64
- removed some warning in ldpc decoder generator for x86_64
- char
- Delete irrelevant constants
- Correctly declare variables
- Define stdbool for all architectures
- Remove definition of _MM_SHUFFLE and use SIMDE_MM_SHUFFLE
- Remove commented code
- Fix CMakeLists.txt
- Include SIMDE avx2 functions in tools_defs.h

Raymond Knopp f6bb869c0b fixed AVX2 issue for cnProc code generator. Some cleanup in formatting and deleting unused files. 2022-06-12 23:23:07 +02:00
Robert Schmidt 169f42a365 Prevent #define name clash 
The files openair1/PHY/CODING/nrLDPC_cnProc.h and
openair1/PHY/CODING/nrLDPC_decoder/nrLDPC_cnProc.h have the same name,
and also the same include guard/define. This commit renames the define
in the latter to prevent this name clash.
