[llvm-commits] [PATCH] review for MC ELF header e_flags setting

[Carter, Jack]

This is not a rehash of an old patch.

Currently gathering information such as symbol, section and data is done by collecting it in an MCAssembler object. From MCAssembler and MCAsmLayout objects ELFObjectWriter::WriteObject() forms and streams out the ELF object file.

This patch just adds a few members to the MCAssember class to store and access the e_flag settings. It allows for runtime additions to the e_flag by assembler directives. The standalone assembler can get to MCAssembler from getParser().getStreamer().getAssembler().

The downside is that I am putting an ELF specific data member in MCAssembler (right next to an existing MACH specific member). We probably should have an MCELFAssembler object down the road.

I have looked at the ARMELFStreamer files and I do not see how they apply to the e_flag bit field data storage.

Please review and comment.

Regards,

Jack
