Make sure we emit a section for pubnames even if that section is going to be empty. This is particularly important for the gnu pubnames case since we're emitting a relocation to the section. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191915 91177308-0d34-0410-b5e6-96231b3b80d8 2013-10-03 17:41:20 +00:00			`; RUN: llc -mtriple=x86_64-pc-linux-gnu -generate-gnu-dwarf-pub-sections -filetype=obj < %s \| llvm-dwarfdump - \| FileCheck %s`

DebugInfo: Tag units as having been indexed in GNU pubnames by using a DW_AT_GNU_pubnames of DW_FORM_flag(_present) rather than sec_offsets to the pubnames/types sections This is consistent with GDB ToT and reduces the number of relocations in (type and compile) units, substantially reducing relocations and debug size in fission + type units builds. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203082 91177308-0d34-0410-b5e6-96231b3b80d8 2014-03-06 05:47:39 +00:00			`; CHECK: DW_AT_GNU_pubnames [DW_FORM_flag_present] (true)`

DebugInfo: Remove some unneeded conditionals now that DIBuilder no longer emits zero-length arrays as {i32 0} A bunch of test cases needed to be cleaned up for this, many my fault - when implementid imported modules I updated test cases by simply duplicating the prior metadata field - which wasn't always the empty metadata entry. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200731 91177308-0d34-0410-b5e6-96231b3b80d8 2014-02-04 01:23:52 +00:00			`!2 = metadata !{}`
