Bold just got faster!

Compared to v0.1.0, we notice a 1.19x speed-up when linking Zig stage3 compiler:

Benchmark 1: ./bold.sh
  Time (mean ± σ):     968.2 ms ±   4.5 ms    [User: 3015.3 ms, System: 959.4 ms]
  Range (min … max):   960.0 ms … 972.8 ms    10 runs

Benchmark 2: ./bold-0.1.0.sh
  Time (mean ± σ):      1.148 s ±  0.016 s    [User: 4.639 s, System: 0.903 s]
  Range (...

zld is now bold

I have renamed zld and then emerald to bold and made it a Mach-O only linker. I needed to face the harsh reality that I will not be able to develop and maintain multiple drivers at the same time and so I've decided to focus on Mach-O only. If anyone is interested in carrying on the work with the other drivers however, the source code is archived and available in [ku...

Implement -r mode for the Mach-O linker.

A complete MachO driver rewrite + ELF x86_64 support

• MachO driver has been fully redesigned mainly so that we can easily plug it in into Zig much like we did with the ELF driver.
• This is the first tagged release of the ELF x86_64 driver.
• Thanks to @Luukdegram we also get some Wasm linker support 🎉

Better MachO link times (on Apple Silicon)

Seems we have regressed in link tim...

The major achievement of this release is in rewriting of the majority of the MachO linker in the spirit of data-oriented design which led to

• significantly reduced link times to the point where, dare I say, we start to become competitive with lld and ld64 - you can find some numbers below, and
• reduced memory usage by avoiding unnecessary allocs, and instead re-parsing data when actually n...
