Yes, zero-extend is clear in document. The question is XED ignores the register ordinal besides the size. nasm input ``` VEXTRACTPS r8, xmm1, 2 VEXTRACTPS rax, xmm1, 2 ``` nasm...

Sorry for my fast test. IMO the result of General-B8 is more consistent and better than semantically equivalence.

Thanks. I did a tool based NASM database. I found it is convenient if we treat mask or mask|z as a prefix. Because {k1} {k1}{z} only applied to the first...

Yes. We can take it as a prefix as well, just like MASK. So it is designed for extended usage. And the low needle of the imm byte maybe has...

Another one: The 2 decorations SAESTR and ROUNDC strictly correspond to SAE() and AVX512_ROUND() in FIX_ROUND_LEN128/512 situations. Just remove them from operands, let pattern take care. And since it's just...

太多小对象了,考虑使用BufferedObject技巧,创建大缓冲区,将对象直接转换为字面值方式.这个与C中内存管理相似,此时对象使用int表示,所有操作在环境中执行,这个int可以解释为对象,此方式对于GC相当友好.可以找一下github上的项目HugeXXX

or use the option -XX:-UseGCOverheadLimit
