I didn’t mean to suggest changing any of that, x87 is part of the 32-bit x86 ABI, and we can't change that. What I meant is making long double a 64-bit built-in C type, i.e. sizeof(long double) == 8. The compiler could generate the same code for long double as it currently does for double (aside from differences in built-in function names).
After a little discussion with Martin on IRC, we agree that this series of patches are acceptable.The ARM64EC thunks will be responsible for conversion between x87 and ARM64 `long double`. It will be another topic.
