2007-05-14Give names to the final result values of the part_set computations. ThisReid Spencer
just aids in readability and debugability of the output. No functional change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37037 91177308-0d34-0410-b5e6-96231b3b80d8
2007-05-13Emit function debug frames in one atom. This will prevent us from generating ↵Anton Korobeynikov
incorrect assembler in case of both debug information & exception information presented. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37019 91177308-0d34-0410-b5e6-96231b3b80d8
2007-05-13Emit multiple common EH frames for multiple (including blank) personalityAnton Korobeynikov
functions. This partly fixes PR1414: now we're restricted only to one personality function per eh frame, not per module. Further work on "multiple personalities" topic needs representative example. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37018 91177308-0d34-0410-b5e6-96231b3b80d8
2007-05-12More DWARF-related things cleanup:Anton Korobeynikov
1. Fix PR1380 2. Apply Duncan's patch from PR1410 3. Insert workaround for "one personality function per module" as noted in PR1414 4. Emit correct debug frames for x86/linux. This partly fixes DebugInfo/2006-11-06-StackTrace.cpp: stack trace is shown correctly, but arguments for function on top of stack are displayed incorrectly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37015 91177308-0d34-0410-b5e6-96231b3b80d8

2007-05-01Under normal circumstances, when a frame pointer is not required, we reserveEvan Cheng
argument space for call sites in the function immediately on entry to the current function. This eliminates the need for add/sub sp brackets around call sites. However, this is not always a good idea. If the "call frame" is large and the target load / store instructions have small immediate field to encode sp offset, this can cause poor codegen. In the worst case, this can make it impossible to scavenge a register if the reserved spill slot is pushed too far apart from sp / fp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@36607 91177308-0d34-0410-b5e6-96231b3b80d8
