H. Peter Anvin (Intel) 3d6b642931 sse2avx: add an [SSE2AVX] directive to generate AVX (V-) instructions
It can preferable to generate AVX code over SSE code, since the AVX
code clears the upper part of registers and so on.

Add a [sse2avx on] directive that does this.

This is handled by yet another layer of instruction database
preprocessing, which looking for V... instructions with the same
operand signature as a corresponding SSE instruction.

NASM, the Netwide Assembler

master

Many many developers all over the net respect NASM for what it is: a widespread (thus netwide), portable (thus netwide!), very flexible and mature assembler tool with support for many output formats (thus netwide!!).

Now we have good news for you: NASM is licensed under the "simplified" (2-clause) BSD license. This means its development is open to even wider society of programmers wishing to improve their lovely assembler.

Visit our nasm.us website for more details.

With best regards, the NASM crew.
