I've successful compiled jWasm for DOS, version 2.13. It supports now AVX and AVX2 - thank you, Habran for the excellent work.
JWASM.EXE runs in DOS 32bit protected-mode. It requires a 80386 cpu and needs a MS-DOS v5 compatible DOS to run. Long filenames (LFN) are supported. It won't run on 64-bit Windows.
I've tested the EXE under plain DOS and under virtual machines (VMWare and VirtualBox). The EXE is compiled with gcc for DOS, version 4.7.3.
Habran is currently working on a major update, which supports AVX512 etc. He'll need a bit time for that. My contribution was very small. I did only help a bit by the compilation. I'll try next to compile the BSD and Linux version. Probably I can provide a bit Web space for downloading the binaries and sources, but that will take a little while.
Some test reports for version 2.13 would be fine. Have fun.
