DIEs are created from MDNode, which are already uniqued. And DwarfDebug already uses ValueMaps to find and use existing DIE for a given MDNode.

Use ValueMap, instead of std::map.

"Attach debug info with llvm instructions" mode was enabled a month ago. Now make it permanent and remove old way of inserting intrinsics to encode debug info for line number and scopes.

While calculating original type size for a derived type, handle type variants encoded as DIDerivedType appropriately.
This improves bitfield support.

llvm-svn: 86073

Fix DW_AT_data_member_location for bit-fields. It points to the location of annonymous field that covers respective field.

warning from gcc by removing VISIBILITY_HIDDEN attributes.

Do not held on to DenseMap slot accross map insertion. The insertion may cause the map to grow rending the slot invalid.
Use this opportunity to use ValueMap instead of DenseMap.

If there is not any llvm instruction associated with each lexical scope encoded in debug info then create such scope on demand for variable info.

Extract scope information from the variable itself, instead of relying on alloca or llvm.dbg.declare location.

While recording beginning of a function, use scope info from the first location entry instead of just relying on first location entry itself.

Check invalid debug info for enums. This may happen when underlyng enum is optimized away. Eventually DwarfChecker will clean this up during llvm verification stage.

Do not record line number to implicitly mark start of function if function has arguments. Extra line number entries trip gdb in some cases.

Existence of a compile unit for input source file is a good indicator to check debug info's presence in a module.

llvm-svn: 83348

This can happen if debug info is processed lazily.

void foo() { static int bar = 42; }
Here, foo's DIE is parent of bar's DIE.
