Description
Hi,
I am trying to convert openblas to go with this project.
A simple C code:
// degmm.c
#include <cblas.h>
void degmm()
{
int i=0;
double A[6] = {1.0,2.0,1.0,-3.0,4.0,-1.0};
double B[6] = {1.0,2.0,1.0,-3.0,4.0,-1.0};
double C[9] = {.5,.5,.5,.5,.5,.5,.5,.5,.5};
cblas_dgemm(CblasColMajor, CblasNoTrans, CblasTrans,3,3,2,1,A, 3, B, 3,2,C,3);
}
int main () {
degmm();
}Use the following command:
clang-6.0 -O3 -mavx -mfma -masm=intel -fno-asynchronous-unwind-tables -fno-exceptions -fno-rtti -S degmm.cWill give the following asm code degmm.s:

Then converting to go asm:
c2goasm -a degmm.s Degmm.sReport the following error:
