From df98617b23315e427cc4fad8ccfdd50d68bec2f9 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Fri, 2 Jan 2009 07:01:27 +0000 Subject: Reimplement the old and horrible bison parser for .ll files with a nice and clean recursive descent parser. This change has a couple of ramifications: 1. The parser code is about 400 lines shorter (in what we maintain, not including what is autogenerated). 2. The code should be significantly faster than the old code because we don't have to work around bison's poor handling of datatypes with ctors/dtors. This also makes the code much more resistant to memory leaks. 3. We now get caret diagnostics from the .ll parser, woo. 4. The actual diagnostics emited from the parser are completely different so a bunch of testcases had to be updated. 5. I now disallow "%ty = type opaque %ty = type i32". There was no good reason to support this, it was just an accident of the old implementation. I have no reason to think that anyone is actually using this. 6. The syntax for sticking a global variable has changed to make it unambiguous. I don't think anyone is depending on this since only clang supports this and it is not solid yet, so I'm not worried about anything breaking. 7. This gets rid of the last use of bison, and along with it the .cvs files. I'll prune this from the makefiles as a subsequent commit. There are a few minor cleanups that can be done after this commit (suggestions welcome!) but this passes dejagnu testing and is ready for its time in the limelight. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61558 91177308-0d34-0410-b5e6-96231b3b80d8 --- tools/bugpoint/BugDriver.cpp | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'tools/bugpoint/BugDriver.cpp') diff --git a/tools/bugpoint/BugDriver.cpp b/tools/bugpoint/BugDriver.cpp index 19f9685677..d050b59ed7 100644 --- a/tools/bugpoint/BugDriver.cpp +++ b/tools/bugpoint/BugDriver.cpp @@ -23,6 +23,7 @@ #include "llvm/Support/CommandLine.h" #include "llvm/Support/FileUtilities.h" #include "llvm/Support/MemoryBuffer.h" +#include "llvm/Support/raw_ostream.h" #include #include using namespace llvm; @@ -80,8 +81,8 @@ Module *llvm::ParseInputFile(const std::string &Filename) { Result = ParseBitcodeFile(Buffer.get()); ParseError Err; - if (!Result && !(Result = ParseAssemblyFile(Filename, &Err))) { - std::cerr << "bugpoint: " << Err.getMessage() << "\n"; + if (!Result && !(Result = ParseAssemblyFile(Filename, Err))) { + Err.PrintError("bugpoint", errs()); Result = 0; } -- cgit v1.2.3
