2019-10-18[LLD] [COFF] Try to report source locations for duplicate symbolsMartin Storsjo
This fixes the second part of PR42407. For files with dwarf debug info, it manually loads and iterates .debug_info to find the declared location of variables, to allow reporting them. (This matches the corresponding code in the ELF linker.) For functions, it uses the existing getFileLineDwarf which uses LLVMSymbolizer for translating addresses to file lines. In object files with codeview debug info, only the source location of duplicate functions is printed. (And even there, only for the first input file. The getFileLineCodeView function requires the object file to be fully loaded and initialized to properly resolve source locations, but duplicate symbols are reported at a stage when the second object file isn't fully loaded yet.)

2019-10-17[lld][test] Fix use of escape character in an lld test on WindowsJordan Rupprecht
Summary: Glob support was improved to accept `\` as an escape character in r375051, but reverted as r375052 due to a failure in this test on Windows. The reason this failure seems Windows specific is because the path separator `\` is currently being relied on to be interpreted literally instead of as an escape character. Per documentation on linker input section wildcard patterns, this seems to be a bug in lld accepting `\` as a literal instead of an escape character. For example: ``` SECTIONS{ .foo :{ /path/to/foo.o(.foo) }} # OK: standard UNIX path SECTIONS{ .foo :{ C:/path/to/foo.o(.foo) }} # OK: windows accepts slashes in either direction SECTIONS{ .foo :{ C:\\path\\to\\foo.o(.foo) }} # OK: escape character used to match a literal \ SECTIONS{ .foo :{ C:\path\to\foo.o(.foo) }} # BAD: this actually matches the path C:pathtofoo.o(.foo) ``` This avoids the problem in the test by using `%/T` in place of `%T` to normalize the path separator to `/`, which windows should also accept. This patch just fixes the test, and glob support will be be relanded separately.

2019-10-17[lld][WebAssebmly] Preserve custom import attributes with LTOSam Clegg
Undefined symbols in WebAssembly can come with custom `import-module` and `import-field` attributes. However when reading symbols from bitcode object files during LTO those curtom attributes are not available. Once we compile the LTO object and read in the symbol table from the object file we have access to these custom attributes. In this case, when undefined symbols are added and a symbol already exists in the SymbolTable we can't simple return it, we may need to update the symbol's attributes.

2019-10-10[PDB] Fix bug when using multiple PCH header objects with the same name.Zachary Turner
A common pattern in Windows is to have all your precompiled headers use an object named stdafx.obj. If you've got a project with many different static libs, you might use a separate PCH for each one of these. During the final link step, a file from A might reference the PCH object from A, but it will have the same name (stdafx.obj) as any other PCH from another project. The only difference will be the path. For example, A might be A/stdafx.obj while B is B/stdafx.obj. The existing algorithm checks only the filename that was passed on the command line (or stored in archive), but this is insufficient in the case where relative paths are used, because depending on the command line object file / library order, it might find the wrong PCH object first resulting in a signature mismatch. The fix here is to simply check whether the absolute path of the PCH object (which is stored in the input obj file for the file that references the PCH) *ends with* the full relative path of whatever is specified on the command line (or is in the archive).

2019-10-09Unify the two CRC implementationsHans Wennborg
David added the JamCRC implementation in r246590. More recently, Eugene added a CRC-32 implementation in r357901, which falls back to zlib's crc32 function if present. These checksums are essentially the same, so having multiple implementations seems unnecessary. This replaces the CRC-32 implementation with the simpler one from JamCRC, and implements the JamCRC interface in terms of CRC-32 since this means it can use zlib's implementation when available, saving a few bytes and potentially making it faster. JamCRC took an ArrayRef<char> argument, and CRC-32 took a StringRef. This patch changes it to ArrayRef<uint8_t> which I think is the best choice, and simplifies a few of the callers nicely.

2019-10-08Report error if -export-dynamic is used with -rRui Ueyama
The combination of the two flags doesn't make sense. And other linkers seem to just ignore --export-dynamic if --relocatable is given, but we probably should report it as an error to let users know that is an invalid combination.

2019-10-07[ELF] Wrap things in `namespace lld { namespace elf {`, NFCFangrui Song
This makes it clear `ELF/**/*.cpp` files define things in the `lld::elf` namespace and simplifies `elf::foo` to `foo`.

2019-10-07[ELF][MIPS] Use lld::elf::{read,write}* instead of ↵Fangrui Song
llvm::support::endian::{read,write}* This allows us to delete `using namespace llvm::support::endian` and simplify D68323. This change adds runtime config->endianness check but the overhead should be negligible.

This patch adds /reproduce:<path> option to lld/COFF. This is an lld-specific option, so we can name it freely.
