* Add support for a new extension to the .file directive:Nick Lewycky2011-10-171-15/+13
| | | | | | | | | | .file filenumber "directory" "filename" This removes one join+split of the directory+filename in MC internals. Because bitcode files have independent fields for directory and filenames in debug info, this patch may change the .o files written by existing .bc files. llvm-svn: 142300
* Add a new wrapper node for a DILexicalBlock that encapsulates it and aEric Christopher2011-10-111-0/+4

This helps with code like in clang's test/CodeGen/debug-info-line.c where we have multiple #line directives within a single lexical block and want to generate only a single block that contains each file change.

* Typo.Eric Christopher2011-10-031-1/+1

* Do not use named md nodes to track variables that are completely optimized. ↵Devang Patel2011-08-191-36/+23
| | | | | | This does not scale while doing LTO with debug info. New approach is to include list of variables in the subprogram info directly. llvm-svn: 138145
* Eliminate unnecessary forwarding function.Devang Patel2011-08-181-16/+3
| | | | llvm-svn: 138006
* Until now all debug info MDNodes referred to a root MDNode, a compile unit. ↵Devang Patel2011-08-161-91/+82
| | | | | | | | This simplified handling of these needs in dwarf writer. However, one side effect of this is that during link time optimization all these MDNodes are _not_ uniqued. In other words there will be N number of MDNodes describing "int", "char" and all other types, which would suddenly grow when each object file starts using libraries like STL. MDNodes graph structure such that compiler unit keeps track of important MDNodes and update dwarf writer to process mdnodes top-down instead of bottom up. llvm-svn: 137778

| | | | | | | | | | | | | | | | | | | inlined variable, based on the discussion in PR10542. This explodes the runtime of several passes down the pipeline due to a large number of "copies" remaining live across a large function. This only shows up with both debug and opt, but when it does it creates a many-minute compile when self-hosting LLVM+Clang. There are several other cases that show these types of regressions. All of this is tracked in PR10542, and progress is being made on fixing the issue. Once its addressed, the re-instated, but until then this restores the performance for self-hosting and other opt+debug builds. Devang, let me know if this causes any trouble, or impedes fixing it in any way, and thanks for working on this! llvm-svn: 136953
