Revert "Revert "Remove the darwin gdb option, that version of gdb is now dead and the rest of the compatibility should be done on a dwarf-N level."" This reverts commit r189913. Talked with Eric on IRC. I am going to XFAIL the failing test since it is using what Eric described as "the member hack" which was needed on that old GDB. Sorry for the noise! llvm-svn: 189914

llvm-dwarfdump: Replace -debug-dump=sect option with individual options. As discussed on llvm-dev in http://lists.llvm.org/pipermail/llvm-dev/2017-September/117301.html this changes the command line interface of llvm-dwarfdump to match the one used by the dwarfdump utility shipping on macOS. In addition to being shorter to type this format also has the advantage of allowing more than one section to be specified at the same time. In a nutshell, with this change $ llvm-dwarfdump --debug-dump=info $ llvm-dwarfdump --debug-dump=apple-objc becomes $ dwarfdump --debug-info --apple-objc Differential Revision: https://reviews.llvm.org/D37714 llvm-svn: 312970

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. Fixes rdar://11043421 llvm-svn: 162493

Emit correct linkage-name attribute based on DWARF version. There are still 4 tests that check for DW_AT_MIPS_linkage_name, because they specify DWARF 2 or 3 in the module metadata. So, I didn't create an explicit version-based test for the attribute. Differential Revision: http://reviews.llvm.org/D8227 llvm-svn: 231880

Renumber testcase metadata nodes after r290153. This patch renumbers the metadata nodes in debug info testcases after https://reviews.llvm.org/D26769. This is a separate patch because it causes so much churn. This was implemented with a python script that pipes the testcases through llvm-as - | llvm-dis - and then goes through the original and new output side-by side to insert all comments at a close-enough location.

[opaque pointer type] Add textual IR support for explicit type parameter to load instruction Essentially the same as the GEP change in r230786.

Canonicalize the representation of empty an expression in DIGlobalVariableExpression This change simplifies code that has to deal with DIGlobalVariableExpression and mirrors how we treat DIExpressions in debug info intrinsics. Before this change there were two ways of representing empty expressions on globals, a nullptr and an empty !DIExpression(). If someone needs to upgrade out-of-tree testcases: perl -pi -e 's/(!DIGlobalVariableExpression\(var: ![0-9]*)\)/\1, expr: !DIExpression())/g' <MYTEST.ll> will catch 95%. llvm-svn: 312144
