a temp label at unknown location. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104740 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-26Identify instructions, that needs a label to mark debug info entity, in ↵Devang Patel
advance. This simplifies beginScope(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104720 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-20Split DbgVariable. Eventually, variable info will be communicated through ↵Devang Patel
frame index, or DBG_VALUE instruction, or collection of DBG_VALUE instructions. Plus each DbgVariable may not need a label. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104233 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-07Disable the new unknown-location code for now. It causes a majorDan Gohman
increase in the debug line info section, and it's causing regressions in a gdb testsuite. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103226 91177308-0d34-0410-b5e6-96231b3b80d8
