Was HLA (High Level Assembly) one of those? I did look into it, but I always
preferred to be explicit about the instructions I used. When I use assembler,
it is because I am targetting an explicit instruction set and want to make the
decisions about which instructions to use myself. The one time I thought a
"generic" solution would be useful is when I want assembler that runs on both
32bit and 64bit Intel natively.
Otherwise, I just use C as my generic assembler, with intrinsics where need be.
