Dear arm porters,
I was trying to port bolt-lmm package, which currently builds only on
amd64, i386
and ppc to more archs - particularly arm. I am trying to workaround amd64-specific
SIMD intrinsics with the libsimde-dev (SIMDEverywhere package) - debian
wiki here[1]
I've committed the patch I used here[2]. Along with this, I had
added in "-DSIMDE_ENABLE_OPENMP -fopenmp-simd" to CFLAGS and CXXFLAGS in
the box I built this in.
I am able to get it building on arm64 box, but it does
not seem to run the right way. It seems to trigger the bolt command
again while trying to
make initial guess - don't know why.
I used the same command as used in autopkgtest to test it out. You can
find the sample correct
output for this here[3]
Log pasted at the end of the e-mail. I'd appreciate any help.
