David Blaikie 0d221159a0 Remove the unused 4th operand for DIFile debug info metadata 
llvm-svn: 176983
 2013-03-13 22:05:21 +00:00
David Blaikie 1ca2f36289 Refactor filename/directory in DICompileUnit into a DIFile 
This is the next step towards making the metadata for DIScopes have a common
prefix rather than having to delegate based on their tag type.

David Blaikie a4f770d51c Update debug info test cases with empty SplitDebugFilename field. 
This could be 'null' or the empty string, DIDescriptor::getStringField
coalesces the two cases anyway so it's just a matter of legible/efficient
representation.

The change in behavior of the DICompileUnit::get* functions could be
subsumed by the full verification check - but ideally that should just be an
assertion if we could front-load the actual debug info metadata failure paths.

David Blaikie 33111dfea0 Remove the (apparently) unnecessary debug info metadata indirection. 
The main lists of debug info metadata attached to the compile_unit had an extra
layer of metadata nodes they went through for no apparent reason. This patch
removes that (& still passes just as much of the GDB 7.5 test suite). If anyone
can show evidence as to why these extra metadata nodes are there I'm open to
reverting this patch & documenting why they're there.

Eli Bendersky e6abe83258 Now that llvm-dwarfdump supports flags to specify which DWARF section to dump, 
use them in tests that run llvm-dwarfdump. This is in order to make tests as
specific as possible.

Eric Christopher aec8a82694 Patch to set is_stmt a little better for prologue lines in a function. 
This enables debuggers to see what are interesting lines for a
breakpoint rather than any line that starts a function.

Eric Christopher b81e2b403c Fix thinko check for number of operands to be the one that actually 
might have more than 19 operands. Add a testcase to make sure I
never screw that up again.
