* Remove \brief commands from doxygen comments.Adrian Prantl2018-05-091-1/+1
| | | | | | | | | | | | | | | | | | | This is similar to the LLVM change https://reviews.llvm.org/D46290. We've been running doxygen with the autobrief option for a couple of years now. This makes the \brief markers into our comments redundant. Since they are a visual distraction and we don't want to encourage more \brief markers in new code either, this patch removes them all.

* [MC] Change AsmParser to leverage Assembler during evaluationNirav Dave2018-04-301-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Teach AsmParser to check with Assembler for when evaluating constant expressions. This improves the handing of preprocessor expressions that must be resolved at parse time. This idiom can be found as assembling-time assertion checks in source-level assemblers. Note that this relies on the MCStreamer to keep sufficient tabs on Section / Fragment information which the MCAsmStreamer does not. As a result the textual output may fail where the equivalent object generation would pass. This can most easily be resolved by folding the MCAsmStreamer and MCObjectStreamer together which is planned for in a separate patch. Currently, this feature is only enabled for assembly input, keeping IR compilation consistent between assembly and object generation.

* Revert "Revert r305164/5/7."Saleem Abdulrasool2017-06-231-3/+16
| | | | | | | | | | | | | | | | | | | | | | | Restore the `-gz` option to the driver with some minor tweaks to handle the additional case for `-Wa,--compress-debug-sections`. This intends to make the compression of the debug information controllable from the driver. The following is the behaviour: -gz enable compression (ambiguous for format, will default to zlib-gnu) -gz=none disable compression -gz=zlib-gnu enable compression (deprecated GNU style zlib compression) -gz=zlib enable compression (zlib based compression) Although -Wa,-compress-debug-sections works, it should be discouraged when using the driver to invoke the assembler. However, we permit the assembler to accept the GNU as style argument --compress-debug-sections to maintain compatibility. Note, -gz/-gz= does *NOT* imply -g. That is, you need to additionally specific -g for debug information to be generated. llvm-svn: 306115
* Revert r305164/5/7.Daniel Jasper2017-06-121-16/+3
| | | | | | | | | | | | | | cc1as does not currently access the "--" version of this flag. At the very least this needs to be fixed and proper test cases need to be added. Simple reproducer: clang -Wa,--compress-debug-sections /tmp/test.cc Result: error: unknown argument: '--compress-debug-sections' llvm-svn: 305182
* Driver: add support for `-gz` and `-gz=`Saleem Abdulrasool2017-06-111-3/+16
| | | | | | | | | | | | | | | | | These options control the behaviour of the compression of debug info sections on ELF targets. Our behaviour slightly diverges from the behaviour of GCC. `-gz` maps to the `-compress-debug-sections` rather than `-compress-debug-sections=zlib` or `-compress-debug-sections=zlib-gnu`. This small divergence allows us to be compatible across versions of binutils (=zlib support was introduced in 2.26, while earlier versions only support =zlib-gnu). This also allows users to not have to worry about the version of the assembler they may be using if they are not using the IAS. Previously, users would have had to go through the internal option `-compress-debug-sectionss` and pass that through to the assembler, which is no longer needed. llvm-svn: 305165
* Represent debug information compression type fullySaleem Abdulrasool2017-06-091-4/+6
| | | | | | | | | | | This is tied with the LLVM side of the change to expose the debug information compression types to clang. We now track the compression type as an enumeration rather than a boolean. We still use the same value (GNU) that we did previously. This is in preparation to support passing down the compression type and switch it based on the command line. llvm-svn: 305039

* Stop messing with the 'g' group of options in CompilerInvocation.Douglas Katzman2015-10-081-8/+3
| | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | and related. NFC. Summary: This is the first patch in the series to migrate Triple's (which are ambiguous) to TargetTuple's (which aren't). For the moment, TargetTuple simply passes all requests to the Triple object it holds. Once it has replaced Triple, it will start to implement the interface in a more suitable way. This change makes some changes to the public C++ API. In particular, InitMCSubtargetInfo(), createMCRelocationInfo(), and createMCSymbolizer() now take TargetTuples instead of Triples. The other public C++ API's have been left as-is for the moment to reduce patch size. This commit also contains a trivial patch to clang to account for the C++ API change.
