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

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

The KILL pseudo-instruction may survive to the asm printer pass, just like the IMPLICIT_DEF. Print the KILL as a comment instead of just leaving a blank line in the output.

With -asm-verbose=0, a blank line is printed, like IMPLICIT?DEF.

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.

VISIBILITY_HIDDEN removal.

Chris claims we should never have visibility_hidden inside any .cpp file but
that's still not true even after this commit.

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.

verbose-asm mode, print comments instead. This eliminates a non-comment
difference between verbose-asm mode and non-verbose-asm mode.

Also, factor out the relevant code out of all the targets and into
target-independent code.

Update processDebugLoc() so that it can be used to process debug info before and after printing an instruction.

This will be used by processDebugLoc().

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

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.

the new predicates I added) instead of going through a context and doing a
pointer comparison.  Besides being cheaper, this allows a smart compiler
to turn the if sequence into a switch.

Add support to extract lexical scope information from DebugLoc attached with an machine instruction.
