Hi Nico, Thanks for your information, it indeed works! But it seems that the @if and @ifnot annotations can't handle two conditions at once like `@if(V8_TARGET_ARCH_LOONG64 || V8_TARGET_ARCH_MIPS64)`, and I didn't find something like `@elif`. I thinks MIPS64 is likely need this change too, but add @if(MIPS64) and @ifnot(MIPS64) in @ifnot(LOONG64) seems ugly. Do you have any suggestions? Thank you very much!
