Recommit: Start handling debug line and scope information better: Migrate most of the location setting within the larger API in CGDebugInfo and update a lot of callers. Remove the existing file/scope change machinery in UpdateLineDirectiveRegion and replace it with DILexicalBlockFile usage. Finishes off the rest of rdar://10246360 after fixing a few bugs that were exposed in gdb testsuite testing. llvm-svn: 141893

// RUN: %clang -emit-llvm -S -g %s -o - | FileCheck %s
While handling change of file, check if _current_ file is already seen or not. If current file is seen then it indicates that end of previous file's lexical scope. This fixes radar 8396182. llvm-svn: 114018

PR14566: Debug Info: avoid top level lexical blocks in functions One of the gotchas (see changes to CodeGenFunction) was due to the fix in r139416 (for PR10829). This only worked previously because the top level lexical block would set the location to the end of the function, the debug location would be updated (as per r139416), the location would be set to the end of the function again (but that would no-op, since it was the same as the previous location), then the return instruction would be emitted using the debug location. Once the top level lexical block was no longer emitted, the end-of-function location change was causing the debug loc to be updated, regressing that bug. llvm-svn: 173593

// There are no lexical blocks, but we need two DILexicalBlockFiles to
// correctly represent file info.

DebugInfo: Metadata constructs now start with DI* LLVM r236120 renamed debug info IR constructs to use a `DI` prefix, now that the `DIDescriptor` hierarchy has been gone for about a week. This commit was generated using the rename-md-di-nodes.sh upgrade script attached to PR23080, followed by running clang-format-diff.py on the `lib/` portion of the patch. llvm-svn: 236121
