The asserts in JITThunks::JITThunks complain about the wrong offset values.
Created attachment 64191 [details] Fix the JITStackFrame in Thumb2 JIT with JSValue32_64 A 64 bits wide data is aligned to 8 bytes on ARM by default, but the ..._OFFSET macros in JITStubs.cpp are calculated as the args member is started from the fourth byte. So, the macros are updated and the type of reserved member is replaced with JITStubArg, in order not to make any mistake about the offsets.
Hey Gabor, looks good but I'd like to test this patch doesn't break anything on darwin. I'll test tomorrow morning & land assuming all is good.
