[llvm-commits] [PATCH 0/5] ELF object support

[Matt Fleming]

This series contains the patches that have been sitting in my github
tree that me and Roman Divacky have been working on for a while now. It
isn't a complete implementation but is enough to get a semi-complete
relocatable ELF file emitted.

This is version 2 of the series. I've reworked some of the code based on
comments and feedback from the llvm-commits list and Eli Friedman. The
ELF object writer code is now endian safe, many magic numbers have been
replaced with symbols and MCELFStreamer now inherits from
MCObjectStreamer instead of MCStreamer.

Again, all comments welcome.

Matt Fleming (5):
  ELF entry size support.
  Record a symbol's size which is needed for ELF symbol tables.
  Layout helper function.
  Add ELF ObjectWriter and Streamer support.
  Hookup ELF support for X86.
