| | | | | | | | | | | | | change, now you need a TargetOptions object to create a TargetMachine. Clang patch to follow. One small functionality change in PTX. PTX had commented out the machine verifier parts in their copy of printAndVerify. That now calls the version in LLVMTargetMachine. Users of PTX who need verification disabled should rely on not passing the command-line flag to enable it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145714 91177308-0d34-0410-b5e6-96231b3b80d8
* The dwarf standard says that the only differences between a out-of-lineRafael Espindola2011-11-121-0/+7
| | | | | | | | | | | | | | instance and a concrete inlined instance are the use of DW_TAG_subprogram instead of DW_TAG_inlined_subroutine and the who owns the tree. We were also omitting DW_AT_inline from the abstract roots. To fix this, make sure we mark abstract instance roots with DW_AT_inline even when we have only out-of-line instances referring to them with DW_AT_abstract_origin. FileCheck is not a very good tool for tests like this, maybe we should add a -verify mode to llvm-dwarfdump. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144441 91177308-0d34-0410-b5e6-96231b3b80d8

* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138145 91177308-0d34-0410-b5e6-96231b3b80d8

* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137778 91177308-0d34-0410-b5e6-96231b3b80d8
