2012-06-01Switch all register list clients to the new MC*Iterator interface.Jakob Stoklund Olesen
No functional change intended. Sorry for the churn. The iterator classes are supposed to help avoid giant commits like this one in the future. The TableGen-produced register lists are getting quite large, and it may be necessary to change the table representation. This makes it possible to do so without changing all clients (again). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157854 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-05Patch to set is_stmt a little better for prologue lines in a function.Eric Christopher
This enables debuggers to see what are interesting lines for a breakpoint rather than any line that starts a function. rdar://9852092 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154120 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-03Fix thinko check for number of operands to be the one that actuallyEric Christopher
might have more than 19 operands. Add a testcase to make sure I never screw that up again. Part of rdar://11026482 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153961 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-03Add a line number for the scope of the function (starting at the firstEric Christopher
brace) so that we get more accurate line number information about the declaration of a given function and the line where the function first starts. Part of rdar://11026482 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153916 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-02Revert "Reorder the sections being output to reduce the number of assembler"Eric Christopher
The inline table needs to be constructed ahead of time so that it doesn't try to create new strings while we're emitting everything. This reverts commit a8ff9bccb399183cdd5f1c3cec2bda763664b4b0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151864 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-02Move global variables in TargetMachine into new TargetOptions class. As an APINick Lewycky
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
2011-11-12The dwarf standard says that the only differences between a out-of-lineRafael Espindola
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

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
