If linking directly against a DLL without an import library, the DLL export symbols might not contain stdcall decorations. If we have an undefined symbol with decoration, and we happen to have a matching undecorated symbol (which either is lazy and can be loaded, or already defined), then alias it against that instead. This matches what's done in reverse, when we have a def file declaring to export a symbol without decoration, but we only have a defined decorated symbol. In that case we do a fuzzy match (SymbolTable::findMangle). This case is more straightforward; if we have a decorated undefined symbol, just strip the decoration and look for the corresponding undecorated symbol name. Add warnings and options for either silencing the warning or disabling the whole feature, corresponding to how ld.bfd does it. (This feature works for any symbol decoration mismatch, not only when linking against a DLL directly; ld.bfd also tolerates it anywhere, and also fixes up mismatches in the other direction, like SymbolTable::findMangle, for any symbol, not only exports. But in practice, at least for lld, it would primarily end up used for linking against DLLs.) Differential Revision: https://reviews.llvm.org/D104532 |

LLVM Linker (lld)
This directory and its subdirectories contain source code for the LLVM Linker, a modular cross platform linker which is built as part of the LLVM compiler infrastructure project.
lld is open source software. You may freely distribute it under the terms of the license agreement found in LICENSE.txt.
Benchmarking
In order to make sure various developers can evaluate patches over the same tests, we create a collection of self contained programs.
