Does CONFIG_COMPILER_FLOAT_LIB_FROM_RVFPLIB exist for -s3

Postby srjasz » Thu Jun 27, 2024 4:57 pm

I would like to try CONFIG_COMPILER_FLOAT_LIB_FROM_RVFPLIB but I don't find it in sdkconfig. I found its companion CONFIG_COMPILER_FLOAT_LIB_FROM_GCCLIB.

Thanks

RVfplib is for doing floating points on RISC-V CPUs without an FPU. The ESP32-S3 on the other hand is an Xtensa CPU with an FPU, so no use for RISC-V floating point emulation..
