Devang Patel 2eec32d944 If VariableDIe is not created (may be because global was optimzed away) then do not try to use the variable die.

Devang Patel 2b75ed2c3d Refactor code that finds context for a given die. 
Create global variable DIEs after creating subprogram DIEs. This allows function level static variable's to find their context at the time of DIE creation.

Devang Patel 24c0bb1ca1 Cleanup. 
There is no need to supply ModuleCU to addType() as a parameter.

Dan Gohman 0891d759b5 Don't print a space before the : between the file name and line number. 
And separate the directory and file name with a '/'.

Devang Patel 236526dd18 Emit method definition DIE at module level (even for methods with inlined functino body at soure level) so that the debugger can invoke it. This fixes many test failures in gdb test suite.

Jim Grosbach bf6d35893f Add getFrameIndexReference() to TargetRegisterInfo, which allows targets to 
tell debug info which base register to use to reference a frame index on a
per-index basis. This is useful, for example, in the presence of dynamic
stack realignment when local variables are indexed via the stack pointer and
stack-based arguments via the frame pointer.

 2009-11-21 00:54:03 +00:00
Devang Patel 92e8c655b2 There is no need to use FoldingSet to unique DIEs. 
DIEs are created from MDNode, which are already uniqued. And DwarfDebug already uses ValueMaps to find and use existing DIE for a given MDNode.

 2009-11-21 00:31:03 +00:00
Devang Patel e064ad4741 Do not hold on to a map slot while new entries may be inserted into the map. 
Use ValueMap, instead of std::map.
