* [DWARF] NFC: DWARFDataExtractor combines relocs with DataExtractor.Paul Robinson2017-06-291-6/+5
| | | | | | | | | | | Requires callers to directly associate relocations with a DataExtractor used to read data from a DWARF section, which helps a callee not make assumptions about which section it is reading. This is the next step in reducing DWARFFormValue's dependence on DWARFUnit. Differential Revision: https://reviews.llvm.org/D34704 llvm-svn: 306699
* Sort the remaining #include lines in include/... and lib/....Chandler Carruth2017-06-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | I did this a long time ago with a janky python script, but now clang-format has built-in support for this. I fed clang-format every line with a #include and let it re-sort things according to the precise LLVM rules for include ordering baked into clang-format these days. I've reverted a number of files where the results of sorting includes isn't healthy. Either places where we have legacy code relying on particular include ordering (where possible, I'll fix these separately) or where we have particular formatting around #include lines that I didn't want to disturb in this patch. This patch is *entirely* mechanical. If you get merge conflicts or anything, just ignore the changes in this patch and run clang-format over your #include lines in the files. Sorry for any noise here, but it is important to keep these things stable. I was seeing an increasing number of patches with irrelevant re-ordering of #include lines because clang-format was used. This patch at least isolates that churn, makes it easy to skip when resolving conflicts, and gets us to a clean baseline (again). llvm-svn: 304787

| | | | | | | | | | | | | | | | | | | | | | addition to Low/High PC" With fix of uninitialized variable. Original commit message: This change is intended to use for LLD in D33183. Problem we have in LLD when building .gdb_index is that we need to know section which address range belongs to. Previously it was solved on LLD side by providing fake section addresses with use of llvm::LoadedObjectInfo interface. We assigned file offsets as addressed. Then after obtaining ranges lists, for each range we had to find section ID's. That not only was slow, but also complicated implementation and was the reason of incorrect behavior when sections share the same offsets, like D33176 shows. This patch makes DWARF parsers to return section index as well. That solves problem mentioned above. Differential revision: https://reviews.llvm.org/D33184 llvm-svn: 304078

* [DWARF] - Take relocations in account when extracting ranges from .debug_rangesGeorge Rimar2017-04-241-3/+8
| | | | | | | | | | | | | | | I found this when investigated "Bug 32319 - .gdb_index is broken/incomplete" for LLD. When we have object file with .debug_ranges section it may be filled with zeroes. Relocations are exist in file to relocate this zeroes into real values later, but until that a pair of zeroes is treated as terminator. And DWARF parser thinks there is no ranges at all when I am trying to collect address ranges for building .gdb_index. Solution implemented in this patch is to take relocations in account when parsing ranges. Differential revision: https://reviews.llvm.org/D32228 llvm-svn: 301170

* Move DebugInfo to DebugInfo/DWARF.Zachary Turner2015-01-301-0/+69
In preparation for adding PDB support to LLVM, this moves the DWARF parsing code to its own subdirectory under DebugInfo, and renames LLVMDebugInfo to LLVMDebugInfoDWARF. This is purely a mechanical / build system change. Differential Revision: http://reviews.llvm.org/D7269 Reviewed by: Eric Christopher llvm-svn: 227586
