* Debug Info: Remove special-casing of indirect function argument handling.Adrian Prantl2017-04-181-2/+2
| | | | | | | | | | | | LLVM has changed the semantics of dbg.declare for describing function arguments. After this patch a dbg.declare always takes the *address* of a variable as the first argument, even if the argument is not an alloca. https://bugs.llvm.org/show_bug.cgi?id=32382 rdar://problem/31205000 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@300523 91177308-0d34-0410-b5e6-96231b3b80d8
* Stop messing with the 'g' group of options in CompilerInvocation.Douglas Katzman2015-10-081-1/+1
| | | | | | | | | | | | | | | | With this change, most 'g' options are rejected by CompilerInvocation. They remain only as Driver options. The new way to request debug info from cc1 is with "-debug-info-kind={line-tables-only|limited|standalone}" and "-dwarf-version={2|3|4}". In the absence of a command-line option to specify Dwarf version, the Toolchain decides it, rather than placing Toolchain-specific logic in CompilerInvocation. Also fix a bug in the Windows compatibility argument parsing in which the "rightmost argument wins" principle failed.

* DI: Update testcases for LLVM assembly changeDuncan P. N. Exon Smith2015-07-311-1/+1
| | | | | | | | | | Update testcases after LLVM change r243774. Most of these had no need to check `tag:` field, but did so as a way of getting to the `name:` field. In a few cases I've converted the `tag:` checks to `arg:` or `CHECK-NOT: arg:`. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@243775 91177308-0d34-0410-b5e6-96231b3b80d8
* DebugInfo: Metadata constructs now start with DI*Duncan P. N. Exon Smith2015-04-291-2/+2
| | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@236121 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | This reverts commit r218917, effectively reapplying r218913. Original commit message follows. -- Update debug info testcases for an LLVM metadata schema change to fold metadata constant operands into a single `MDString`.

| | | | | | | This allows us to get rid of an ugly hack in the backend. Paired commit with LLVM. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@190960 91177308-0d34-0410-b5e6-96231b3b80d8
