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	99daf6b263	[C++20] [Modules] Don't handle no linkage entities when overloading ... The original implementation uses `ND->getFormalLinkage() <= Linkage::InternalLinkage`. It is not right since the spec only says internal linkage and it doesn't mention 'no linkage'. This matters when we consider constructors. According to [class.ctor.general]p1, constructors have no name so constructors have no linkage too.	2022-07-26 21:07:41 +08:00
