COFF	[LLD] [COFF] Fix handling of comdat .drectve sections (#68116) This can happen when manually emitting strings into .drectve sections with `__attribute__((section(".drectve")))`, which is a way to emulate `#pragma comment(linker, "...")` for mingw compilers, without requiring building with -fms-extensions. Normally, this doesn't generate any comdat, but if compiled with -fsanitize=address, this section does get turned into a comdat section. This fixes #67261. This issue can be seen as a regression; a change in the "lli" tool in 17.x triggers this case, if compiled with ASAN enabled, triggering this unsupported corner case in LLD. With this change, LLD can handle it. (cherry picked from commit 503bc5f66111f7e4fc79972bb9bfec8bb5606bab)	2 年前
ELF	[ELF][AArch64] Relax zero TLSLE add to nop (#204286) Optimize AArch64 local-exec TLS relocation handling by replacing a self-add R_AARCH64_TLSLE_ADD_TPREL_HI12 instruction with nop when the high 12 bits are zero. The optimization is disabled by --no-relax and avoids non-equivalent forms such as non-self-adds and 32-bit destination registers.	21 天前
MachO	[lld-macho] Implement -no_uuid Since UUID generation in lld is fast this is rarely used but it can be helpful to avoid temporary issues like https://github.com/llvm/llvm-project/issues/63961 Differential Revision: https://reviews.llvm.org/D155735	2 年前
MinGW	[LLD][MinGW] Add --error-limit=<N> option This maps to -errorlimit:<N> in the COFF linker and is functionally identical to the same option in the ELF and MachO linker. Reviewed By: mstorsjo Differential Revision: https://reviews.llvm.org/D137489	3 年前
Unit	Re-land [LLD] Allow usage of LLD as a library This reverts commit aa495214b39d475bab24b468de7a7c676ce9e366. As discussed in https://github.com/llvm/llvm-project/issues/53475 this patch allows for using LLD-as-a-lib. It also lets clients link only the drivers that they want (see unit tests). This also adds the unit test infra as in the other LLVM projects. Among the test coverage, I've added the original issue from @krzysz00, see: https://github.com/ROCmSoftwarePlatform/D108850-lld-bug-reproduction Important note: this doesn't allow (yet) linking in parallel. This will come a bit later hopefully, in subsequent patches, for COFF at least. Differential revision: https://reviews.llvm.org/D119049	3 年前
wasm	[WebAssembly] Stabilize custom section order It currently depends on the StringMap iteration order, which is not guaranteed to be deterministic. Use MapVector to stabilize the order.	2 年前
CMakeLists.txt	[LLD] [COFF] Warn about pseudo relocations that are too narrow In 64 bit mode, any references to symbols that might end up autoimported must be made via full 64 bit pointers (usually in .refptr stubs generated by the compiler). If referenced via e.g. a 32 bit rip relative offset, it might work as long as DLLs are loaded close together in the 64 bit address space, but will fail surprisingly later if they happen to be loaded further apart. Any cases of that happening is usually a toolchain error, and the sooner we can warn about it, the easier it is to diagnose. Differential Revision: https://reviews.llvm.org/D154777	2 年前
lit.cfg.py	[lld][ELF] Support LoongArch This adds support for the LoongArch ELF psABI v2.00 [1] relocation model to LLD. The deprecated stack-machine-based psABI v1 relocs are not supported. The code is tested by successfully bootstrapping a Gentoo/LoongArch stage3, complete with common GNU userland tools and both the LLVM and GNU toolchains (GNU toolchain is present only for building glibc, LLVM+Clang+LLD are used for the rest). Large programs like QEMU are tested to work as well.
