Driver and option support for -gsplit-dwarf. This is a part of the DWARF5 split dwarf proposal. llvm-svn: 174349

// Check that we split debug output properly

Remove the SplitDebug action and replace with a set of commands in the compilation setup. Note that this doesn't currently work for -no-integrated-as. llvm-svn: 175813

Don't pass -split-dwarf= to the backend unless we're on linux for now. llvm-svn: 175814

Make sure we only use the output file as a base for debug splitting if we're compiling. llvm-svn: 175851

Split out the command handling for split debug info, we're going to want to propagate some information through the module into the back end and so need to pass it through to codegen. Also make the methods file static so we can use them in other places. llvm-svn: 175916

If we're splitting the dwarf for fission and don't want to use the integrated assembler then go ahead and still split the dwarf anyhow. Add two tests, one to exercise existing behavior of not splitting when we're just emitting assembly files and the other to test that we split when we're not in integrated as mode. llvm-svn: 183355

Split DWARF: Allow -gmlt/-gsplit-dwarf to override rather than complement each other It doesn't make any sense to enable -gmlt with -gsplit-dwarf, since -gmlt is designed for on-line symbolication (and -gsplit-dwarf normally emits all the -gmlt data into the .o anyway - so there's nothing to split out except redundant/duplicate info). With this change they override each other, -gmlt -gsplit-dwarf is the same as -gsplit-dwarf and -gsplit-dwarf -gmlt is the same as -gmlt. llvm-svn: 243694

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. Differential Revision: http://reviews.llvm.org/D13221 llvm-svn: 249655

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.
