Introduce llvm-install-name-tool

2019-11-20T07:42:37+00:00

This diff adds a new "driver" for llvm-objcopy which is supposed to emulate the behavior of install-name-tool. This is a recommit of b5913e6 with ubsan, test dependencies issues fixed. Differential revision: https://reviews.llvm.org/D69146 Test plan: make check-all

[llvm-objcopy] Add support for shell wildcards

2019-10-17T20:51:00+00:00

Summary: GNU objcopy accepts the --wildcard flag to allow wildcard matching on symbol-related flags. (Note: it's implicitly true for section flags). The basic syntax is to allow *, ?, \, and [] which work similarly to how they work in a shell. Additionally, starting a wildcard with ! causes that wildcard to prevent it from matching a flag. Use an updated GlobPattern in libSupport to handle these patterns. It does not fully match the `fnmatch` used by GNU objcopy since named character classes (e.g. `[[:digit:]]`) are not supported, but this should support most existing use cases (mostly just `*` is what's used anyway).

Unify the two CRC implementations

2019-10-09T09:06:30+00:00

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 argument, and CRC-32 took a StringRef. This patch changes it to ArrayRef which I think is the best choice, and simplifies a few of the callers nicely.

[llvm-objcopy] Add --set-section-alignment

2019-10-02T12:41:25+00:00

Fixes PR43181. This option was recently added to GNU objcopy (binutils PR24942). `llvm-objcopy -I binary -O elf64-x86-64 --set-section-alignment .data=8` can set the alignment of .data.
