Douglas Katzman 3459ce2e5e Stop messing with the 'g' group of options in CompilerInvocation.
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.

David Blaikie ea3e51d73f Account for calling convention specifiers in function definitions in IR test cases
Several tests wouldn't pass when executed on an armv7a_pc_linux triple
due to the non-default arm_aapcs calling convention produced on the
function definitions in the IR output. Account for this with the
application of a little regex.

Duncan P. N. Exon Smith 9dd4e4e63a 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.

Duncan P. N. Exon Smith 3c51fa6aae Revert "Revert "DI: LLVM schema change: fold constants into string""
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`.

Nico Weber bdc969839a Include translation unit filename in global ctor symbol names.
This makes it easier to see where a global ctor comes from, and it also makes
ASan's init order analyzer output easier to understand.  gcc does this too,
but only in -fPIC mode for some reason.  Don't do this for constructors with
explicit init priority.

Also prepend "sub_" before the 'I', that way regular constructors stay
lexicographically after symbols with init priority (because
ord('s') > ord('I')).  gold seems to ignore the name of constructor symbols,
and ld only looks at the symbol if it includes an init priority, which this
patch doesn't change.

Before: __GLOBAL_I_a
Now: __GLOBAL_sub_I_myfile.cc

Adrian Prantl 0ce2b87507 Follow-up to r205999: Emit an artificial location (valid scope, line 0)
for CXXGlobalInit/Dtor helper functions.
This makes _GLOBAL__I_a regain its DW_AT_high/low_pc in the debug info.

Thanks to echristo for catching this!

Adrian Prantl 42d71b9906 Debug info: (Bugfix) Make sure artificial functions like _GLOBAL__I_a
are not associated with any source lines.

Previously, if the Location of a Decl was empty, EmitFunctionStart would
just keep using CurLoc, which would sometimes be correct (e.g., thunks)
but in other cases would just point to a hilariously random location.

This patch fixes this by completely eliminating all uses of CurLoc from
EmitFunctionStart and rather have clients explicitly pass in a
SourceLocation for the function header and the function body.
