Support for RiscV architecture

[anuphalarnkar]

Hi,

I am working to port Pytorch to RiscV.

Platform details: OS: Ubuntu Image: SiFive HiFive unmatched RiscV64 Booted on Qemu

Application details: Pytorch, Sleef

The build fails with error as shown below.

[ 29%] Building C object sleef/src/libm/CMakeFiles/sleefpurecfma_scalar.dir/sleefsimdsp.c.o In file included from /home/ubuntu/pytorch/third_party/sleef/src/libm/sleefsimdsp.c:358: /home/ubuntu/pytorch/third_party/sleef/src/arch/helperpurec_scalar.h:69:2: error: #error FP_FAST_FMA or FP_FAST_FMAF not defined 69 | #error FP_FAST_FMA or FP_FAST_FMAF not defined | ^~~~~ gmake[2]: [sleef/src/libm/CMakeFiles/sleefpurecfma_scalar.dir/build.make:81: sleef/src/libm/CMakeFiles/sleefpurecfma_scalar.dir/sleefsimdsp.c.o] Error 1 gmake[1]: [CMakeFiles/Makefile2:6565: sleef/src/libm/CMakeFiles/sleefpurecfma_scalar.dir/all] Error 2 gmake[1]: Waiting for unfinished jobs.... gmake: [Makefile:146: all] Error 2

I edited the file "sleef/src/arch/helperpurec_scalar.h" and updated the architecture "__riscv" after which the issue was resolved and build proceeded.

Regards, Anup
