From 4969cfc6477c56afb2d4f2f6c1733c3120690b6d Mon Sep 17 00:00:00 2001 From: "jimblandy@gmail.com" Date: Tue, 15 Dec 2009 17:06:21 +0000 Subject: Issue 39002: Breakpad DWARF parser: Move DWARF parser to platform-independent directory. Move the DWARF parser, and the functioninfo.cc DWARF consumer, from src/common/mac/dwarf to src/commmon/dwarf, so that it can be shared between the Mac and Linux dumpers. Fix up #include directives, multiple inclusion protection macros, and Xcode build files. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@446 4c0a9323-5329-0410-9bdc-e9ce6186880e --- src/common/mac/dwarf/bytereader.h | 132 -------------------------------------- 1 file changed, 132 deletions(-) delete mode 100644 src/common/mac/dwarf/bytereader.h (limited to 'src/common/mac/dwarf/bytereader.h') diff --git a/src/common/mac/dwarf/bytereader.h b/src/common/mac/dwarf/bytereader.h deleted file mode 100644 index 299dd9ac..00000000 --- a/src/common/mac/dwarf/bytereader.h +++ /dev/null @@ -1,132 +0,0 @@ -// Copyright 2006 Google Inc.
