2014-12-19[DebugInfo] Move all DWARF headers to the public include directory.Frederic Riss1-1/+1
dsymutil needs access to DWARF specific inforamtion, the small DIContext wrapper isn't sufficient. Other DWARF consumers might want to use it too (I'm looking at you lldb). Differential Revision: http://reviews.llvm.org/D6694 llvm-svn: 224594
2014-09-19Turn local DWARFContext helpers getFileNameForUnit() and ↵Frederic Riss1-5/+33
getFileLineInfoForCompileUnit() into full-blowm DWARFDebugLine::LineTable methods. Summary: getFileNameForUnit() is basically a wrapper around LineTable::getFileNameByIndex(). Fold its additional functionality (adding the DWARFUnit compilation dir) into LineTable::getFileNameByIndex(). getFileLineInfoForCompileUnit() is a wrapper around getFileNameForUnit(). As a function to search the line information by address, it seems natural to put it in the LineTable also. Before this commit only the Context with its private helpers could do Linetable lookups. This newly exposed feature will be used by the DIE dumping code to get access to file information referenced in DIE attributes. This commit has already been partly reviewed in D5192 and contained an additional and a bit controversial 'realpath' call that is left out of this patch. We can reinstate that realpath code later if it is desirable. Test Plan: The patch contains no tests as it should be functionally equivalent to the previous code. As requested in the last review, I checked if the relative path handling copied from the Context to LineTable::getFileNameByIndex() was covered, and indeed the symbolizer tests fail if it is removed.

2014-05-15[DWARF parser] Use enums instead of bitfields in DILineInfoSpecifier.Alexey Samsonov1-3/+5
It is more appropriate than the current situation, when one flag (AbsoluteFilePath) is relevant only if another flag is set. This refactoring would also simplify fetching the short function name (stored in DW_AT_name) instead of a linkage name returned currently. No functionality change. llvm-svn: 208921
2014-04-30[DWARF parser] Cleanup code in DWARFDebugLine.Alexey Samsonov1-88/+85
Streamline parsing and dumping line tables: Prefer composition to multiple inheritance in DWARFDebugLine::ParsingState. Get rid of the weird concept of "DumpingState" structure. was: DWARFDebugLine::DumpingState state(OS); DWARFDebugLine::parseStatementTable(..., state); now: DWARFDebugLine::LineTable LineTable; LineTable.parse(...); LineTable.dump(OS); No functionality change. llvm-svn: 207599
2014-04-29[DWARF parser] Cleanup code in DWARFDebugLine.Alexey Samsonov1-65/+100
Move several function definitions into .cpp, unify constructors and clear() methods (fixing a couple of latent bugs from copy-paste), turn static function parsePrologue() into Prologue::parse(). More work needed here to untangle weird multiple inheritance in table parsing and dumping. No functionality change. llvm-svn: 207579

2014-02-14Support DWARF discriminators in object streamer.Diego Novillo1-3/+9
Summary: This adds support for emitting DWARF path discriminator values in the object streamer. It also changes the DWARF dumper to show discriminator values in the line table output.

and, in the case of ELF files, using symbol addresses when available for relocations to the .debug_info section. Also extending the llvm-rtdyld tool to add the ability to dump line number information for testing purposes. llvm-svn: 173517

2012-08-07Fix the representation of debug line table in DebugInfo LLVM library,Alexey Samsonov1-39/+78
and "instruction address -> file/line" lookup. Instead of plain collection of rows, debug line table for compilation unit is now treated as the number of row ranges, describing sequences (series of contiguous machine instructions). The sequences are not always listed in the order of increasing address, so previously used std::lower_bound() sometimes produced wrong results. Now the instruction address lookup consists of two stages: finding the correct sequence, and searching for address in range of rows for this sequence. llvm-svn: 161414
