2011-11-04Emit declarations before definitions if they are available. This causes ↵Rafael Espindola

2011-10-17Add support for a new extension to the .file directive:Nick Lewycky
.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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142300 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-11Add a new wrapper node for a DILexicalBlock that encapsulates it and aEric Christopher
file. Since it should only be used when necessary propagate it through the backend code generation and tweak testcases accordingly. 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.

2011-08-19Do not use named md nodes to track variables that are completely optimized. ↵Devang Patel
This does not scale while doing LTO with debug info. New approach is to include list of variables in the subprogram info directly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138145 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-16Until now all debug info MDNodes referred to a root MDNode, a compile unit. ↵Devang Patel
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137778 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-15This is somewhat déjà-vu, but avoid using getCompileUnit() as much as ↵Devang Patel

2011-08-15There is no need to maintain a set to keep track of variables that use ↵Devang Patel

2011-08-05Temporarily revert r135528 which distinguishes between two copies of oneChandler Carruth
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! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136953 91177308-0d34-0410-b5e6-96231b3b80d8
