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	e9a7876c2c	[C++20] [Modules] Chose BMI from for module m with the last ... -fmodule-file=<module-name>= option Currently if we have multiple `-fmodule-file=<module-name>=<BMI-path>` flags for the same `<module-name>`, we will pick the BMI-path from the first flag. And this is inconsistent with what users generally expect. e.g, we might expect the latter flags can override the former ones. This patch changes the behavior to match user's expectation.	2023-10-27 16:52:21 +08:00
