David Blaikie 2811f8ac28 [DebugInfo] remove more node indirection (this time from the subprogram's variable lists) 
llvm-svn: 174305
 2013-02-04 05:56:36 +00:00
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 bb69a27dbc Use DW_FORM_flag_present to save space in debug information if we're 
not in darwin gdb compat mode.

Fixes rdar://10975088

Eric Christopher acb7115bde Remove the DW_AT_MIPS_linkage name attribute when we don't need it 
output (we're emitting a specification already and the information
isn't changing) and we're not in old gdb compat mode.

Saves 1% on the debug information for a build of llvm.

Eric Christopher b1b9451337 Temporarily revert c23b933d5f8be9b51a1d22e717c0311f65f87dcd. It's causing 
failures in the debug testsuite and possibly PR13486.

Eric Christopher 86ca9f9e11 Add a DW_AT_high_pc for CUs that are a single address range. Update 
all tests accordingly.

Fixes PR13351.

the DECL information.

Eric Christopher 7dd54fb695 Revert the removal of DW_AT_MIPS_linkage_name when we aren't putting 
out the DW_AT_name. Older gdbs unfortunately still use it to
disambiguate member functions in templated classes (gdb.cp/templates.exp).

Eric Christopher 5cd2a9d98e Only add DW_AT_prototyped if we're working with a C-like language. 
Worth another 45k (1%) off of a large C++ testcase.

Rafael Espindola e7cc8bff82 The dwarf standard says that the only differences between a out-of-line 
instance and a concrete inlined instance are the use of DW_TAG_subprogram
instead of DW_TAG_inlined_subroutine and the who owns the tree.

We were also omitting DW_AT_inline from the abstract roots. To fix this,
make sure we mark abstract instance roots with DW_AT_inline even when
we have only out-of-line instances referring to them with DW_AT_abstract_origin.

FileCheck is not a very good tool for tests like this, maybe we should add
a -verify mode to llvm-dwarfdump.
