What are the differences between armv8.1m libraries #446
Comments
These map on to different compiler command line-options. I would expect We don't currently build an all in armv8.1m.main_hard_fpdp_nomve armv8.1m.main_hard_fp_nomve armv8.1m.main_hard_nofp_mve armv8.1m.main_soft_nofp_nomve |
Thanks! |
Following up #301 with LLVM-ET-Arm-18.1.3-Linux-x86_64
Using -mcpu=cortex-m85 -mfloat-abi=hard, multilib system picks armv8.1m.main_hard_fpdp_nomve. We are not sure it is the best choice for Cotex-M85 device that has a FPU compliant with the ANSI/IEEE Std 754-2008 scalar half, single, and double-precision floating-point operation, and supports MVE/MVE-F.
Could you help to explain the detailed differences between these libraries?
