New Revision: 329613
URL: http://llvm.org/viewvc/llvm-project?rev=329613&view=rev
Log:
[Debuginfo][COFF] Minimal serialization support for precompiled types records
This change adds support for the LF_PRECOMP and LF_ENDPRECOMP records required
to read/write Microsoft precompiled types .objs.
See https://en.wikipedia.org/wiki/Precompiled_header#Microsoft_Visual_C_and_C++
This also adds handling for the .debug$P section, which is actually a .debug$T
section in disguise, found only in precompiled .objs.
