[BUG] CMSIS NN libs compilation error: dereferencing type-punned pointer will break strict-aliasing rules #426

Closed fgr1986 closed 3 years ago

fgr1986 commented 6 years ago

Info When compiled with GCC, -O3 flag and -Werror, the following error appears: dereferencing type-punned pointer will break strict-aliasing rules -Werror needs to be removed to successfully compile.

The problem appears to be due to the __SIMD32(pInA) macro typcasting the pointers to __SIMD32_TYPE which on gcc is int32_t. pInA and pInB on the otherhand are q15_t * (int16_t *)

@nemo8 , @fgr1986 Some very late tidying up here..Sorry about that. No active development is done on the legacy API's that you mention. https://github.com/ARM-software/CMSIS_5/tree/develop/CMSIS/NN#legacy-vs-tfl-micro-compliant-apis has info about the different API's that are available. There are no immediate plans to fix these warnings. If you are using it and would like to make a PR to use API's like in https://github.com/ARM-software/CMSIS_5/pull/656/commits/61d15e506c0a681c2352b87979a2e685c1c0f7ab , you are welcome to do so. With that, I am closing this ticket.
