Dimitry Andric 7213200231 Turn off lldb debug tuning by default for FreeBSD
Summary:
This is the clang part of D15966.  In rL256104, debugger tuning was
added to the clang driver, and again the default for FreeBSD was set to
lldb.  The default needs to be gdb instead.

Paul Robinson 0334a047df Driver part of debugger tuning.
Adds driver options named -glldb and -gsce to mean -g plus tuning for
lldb and SCE debuggers respectively; the existing -ggdb option does
the same for gdb. Existing options -ggdb0, -ggdb1 etc. unpack into
-ggdb -g<N>.  (There will not be -glldb<N> or -gsce<N> options.) The
tuning gets a target-specific default in the driver, and is passed
into cc1 with the new -debugger-tuning option.

As fallout, fixes where '-gsplit-dwarf -g0' would ignore the -g0 part
on Linux.

Filipe Cabecinhas 2432ff59d3 Tweak a -g related test for the PS4
Make sure we're matching what we want:
 - Always have -generate-arange-section (independent of -g)
 - Emit a -dwarf-version=... when -g is there.

Filipe Cabecinhas c888e190ba Bring back r250262: PS4 toolchain
There was a minor problem with a test. Sorry for the noise yesterday.

This patch adds missing pieces to clang, including the PS4 toolchain
definition, added warnings, PS4 defaults, and Driver changes needed for
our compiler.

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.

Adrian Prantl 6b21ab21d1 Add a -gmodules option to the driver and a -dwarf-ext-refs to cc1
to enable the use of external type references in the debug info
(a.k.a. module debugging).

The driver expands -gmodules to "-g -fmodule-format=obj -dwarf-ext-refs"
and passes that to cc1. All this does at the moment is set a flag
codegenopts.

Hal Finkel 4add5dc093 Treat -g1 as -gline-tables-only
-g1 on gcc (and also IBM's xlc) are documented to be very similar to
-gline-tables-only. Our -gline-tables-only might still be more verbose than -g1
on other compilers, but currently we treat -g1 as -g, and so we're producing
much more debug info at -g1 than everybody else. Treating -g1 as
-gline-tables-only brings us much closer to what everyone else is doing.

Diego Novillo 94b276deba Enable -gcolumn-info by default.
This patch flips the default value for -gcolumn-info to be on by
default. I discussed the rationale and provided compile/size data
in:

http://lists.cs.uiuc.edu/pipermail/llvmdev/2014-June/074290.html

This also updates the documentation and some tests that relied on
the lack of column information. Some tests had column information
in the expected output, but it was wrong (the tsan tests). Others
were using the driver to execute.

Manman Ren 38db092083 Debug Info: set default to gdwarf-2 for Darwin.
Darwin systems currently do not support dwarf version 3 or above. When we are
ready, we can bump the default to gdwarf-4 for Darwin.

For other systems, the default is dwarf version 3, if everything goes smoothly,
we can bump the version to 4.

2. Produce driver error on unsupported formats (-gcoff, -gstabs, -gvms) and options (-gtoggle).
3. Recognize and ignore flags -g[no-]strict-dwarf, -g[no-]record-gcc-switches.

Alexey Samsonov 74a3868dbb This patch adds a new Clang compiler flag "-gline-tables-only".
It reduces the amount of emitted debug information:
1) DIEs in .debug_info have types DW_TAG_compile_unit, DW_TAG_subprogram,
DW_TAG_inlined_subroutine (for opt builds) and DW_TAG_lexical_block only.
2) .debug_str contains only function names.
3) No debug data for types/namespaces/variables is emitted.
4) The data in .debug_line is enough to produce valid stack traces with
function names and line numbers.
