Chuanqi Xu	da00c60dae	[C++20] [Modules] Introduce reduced BMI (#75894) ... Close https://github.com/llvm/llvm-project/issues/71034 See https://discourse.llvm.org/t/rfc-c-20-modules-introduce-thin-bmi-and-decls-hash/74755 This patch introduces reduced BMI, which doesn't contain the definitions of functions and variables if its definitions won't contribute to the ABI. Testing is a big part of the patch. We want to make sure the reduced BMI contains the same behavior with the existing and relatively stable fatBMI. This is pretty helpful for further reduction. The user interfaces part it left to following patches to ease the reviewing.	2024-03-08 10:12:51 +08:00
Chuanqi Xu	dc4e85bd79	[C++20] [Modules] Remove hardcoded path to imported module in BMIs ... Close https://github.com/llvm/llvm-project/issues/62707 As we discussed before, we'll forbid the use of implicit generated path for C++20 modules. And as I mentioned in https://github.com/llvm/llvm-project/issues/62707, we've emitted a warning for clang17 and we'll make it a hard error in clang18. And the patch addresses the decision.	2024-01-12 13:47:59 +08:00
Chuanqi Xu	6ceb32a66f	[C++20] [Modules] Handle the linkage of defaulted friend function ... definition correctly Close https://github.com/llvm/llvm-project/issues/61067 Previously we will only handle the defaulted member functions as discardable ODR. But we need to handle defaulted friend function in this way too. Otherwise we may run into the problems the above issue report mentions.	2023-03-07 15:34:33 +08:00
