Note:
1. GCC MACOS issue
The GCC 11.2 toolchain for MACOS may get crash while compiling
float operation function, the following link describe the issue
and give analyse at the issue:

it's seem GCC give a wrong instruction at certain machine which
without architecture features

the new toolchain is not available still, so just disable the MACOS
