makefile for minimap2 for IBM P9

[jasmynp]

Is there a way we can compile the minimap2 code on IBM Power9? We are having issues as it is complaining of the emmintrin.h which is intel specifix and so the makeful uses the -msse2 flag which is causing compilation errors.

See the limitation section of README. Minimap2 only works with x86 with SSE or arm with NEON. It doesn't work with the POWER SIMD instruction set.

Ok. Thanks for the info.

Hi,

If we used an emulator like QEMU, do you know why it wouldn't work to emulate x86 on POWER9?
This site suggests this solution:

@wandreopoulos I don't use QEMU. I guess CPU-level emulation will affect performance. Minimap2 needs to be properly ported to POWER to be efficient.

You may try one of the few methods in the following article.

Thanks, @hasindu2008. I will keep this link in mind. The main problem is that I don't have access to POWER.
