Different enum value of HostAccessINTEL

[ShengYang1]

I'm new to spirv, and I'm just curious why there are different values for HostAccessINTEL, like 6147 in SPIRV-LLVM-Translator, 6188 in SPIRV-Headers, 6168 in SPIR-V specs

Hi, the original preview specification had HostAccessINTEL be 6147, see intel/llvm#5701 . And like this it was implemented and adopted across the software stack. Then the spec has changed and was upstreamed to SPIR-V Registry and Headers (it was split into 2 extensions with different capabilities). Don't be mistaken - new versions is better then the old one, but unfortunately such change is not backward compatible, so we could not reuse old Op code there and had to change it. Note, that currently the translator is aware of both 6147 and 6148 Op Codes that stand for different versions of HostAccessINTEL, hope that answers your question.
