* Add option to include multiple lines in snippets.Richard Smith2017-05-221-0/+3
| | | | | | | | | | | | | When a diagnostic includes a highlighted range spanning multiple lines, clang now supports printing out multiple lines of context if necessary to show the highlighted ranges. This is not yet exposed in the driver, but can be enabled by "-Xclang -fcaret-diagnostics-max-lines -Xclang N". This is experimental until we can find out whether it works well in practice, and if so, what a good default for the maximum number of lines is. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@303589 91177308-0d34-0410-b5e6-96231b3b80d8
* [asan] A clang flag to enable ELF globals-gc.Evgeniy Stepanov2017-05-091-0/+2
| | | | | | | | | | | | This feature is subtly broken when the linker is gold 2.26 or earlier. See the following bug for details: https://sourceware.org/bugzilla/show_bug.cgi?id=19002 Since the decision needs to be made at compilation time, we can not test the linker version.

* Move functionality for handling module maps as inputs from the -emit-moduleRichard Smith2017-04-281-18/+45
| | | | | | | | | | | | | | | | | | | | action to the general FrontendAction infrastructure. This permits applying -E, -ast-dump, -fsyntax-only, and so on to a module map compilation. (The -E form is not currently especially useful yet as there's no good way to take the output and use it to actually build a module.) In order to support this, -cc1 now accepts -x <lang>-module-map in all cases where it accepts -x <lang> for a language we can parse (not ir/ast). And for uniformity, we also accept -x <lang>-header for all such languages (we used to reject for cuda and renderscript), and -x <lang>-cpp-output for all such languages (we used to reject for c, cl, and renderscript). (None of these new alternatives are accepted by the driver yet, so no user-visible changes.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@301610 91177308-0d34-0410-b5e6-96231b3b80d8
* Improve diagnostics for bad -std= flag.Richard Smith2017-04-271-5/+17
| | | | | | | | | | | | Don't list deprecated -std= values (c++0x etc). Only produce one line of output per standard, even if we know it by multiple names. In passing, add missing -std=gnu++03 alias (supported by GCC), and add new spelling '-std=cl1.0' for OpenCL 1.0 for consistency with the other values, with the same meaning as the preexisting '-std=cl'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@301507 91177308-0d34-0410-b5e6-96231b3b80d8

* Don't accept -std= values that would switch us to a different source language.Richard Smith2017-04-261-21/+25
| | | | | | | | | | | | | | | | | | | | | | We already prohibited this in most cases (in r130710), but had some bugs in our enforcement of this rule. Specifically, this prevents the following combinations: * -x c -std=clN.M, which would previously effectively act as if -x cl were used, despite the input being a C source file. (-x cl -std=cNN continues to be disallowed.) * -x c++ -std=cuda, which would previously select C++98 + CUDA, despite that not being a C++ standard. (-x cuda -std=c++NN is still permitted, and selects CUDA with the given C++ standard as its base language. -x cuda -std=cuda is still supported with the meaning of CUDA + C++98.) * -x renderscript -std=c++NN, which would previously form a hybrid "C++ with RenderScript extensions" language. We could support such a thing, but shouldn't do so by accident. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@301497 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | using metadata Since Split DWARF needs to name the actual .dwo file that is generated, it can't be known at the time the llvm::Module is produced as it may be merged with other Modules before the object is generated and that object may be generated with any name. By passing the Split DWARF file name when LLVM is producing object code the .dwo file name in the object file can match correctly. The support for Split DWARF for implicit modules remains the same - using metadata to store the dwo name and dwo id so that potentially multiple skeleton CUs referring to different dwo files can be generated from one llvm::Module. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@301063 91177308-0d34-0410-b5e6-96231b3b80d8
* Add support for editor placeholders to ClangAlex Lorenz2017-04-191-0/+3
| | | | | | | | | | | | | | | | | | | | | | This commit teaches Clang to recognize editor placeholders that are produced when an IDE like Xcode inserts a code-completion result that includes a placeholder. Now when the lexer sees a placeholder token, it emits an 'editor placeholder in source file' error and creates an identifier token that represents the placeholder. The parser/sema can now recognize the placeholders and can suppress the diagnostics related to the placeholders. This ensures that live issues in an IDE like Xcode won't get spurious diagnostics related to placeholders. This commit also adds a new compiler option named '-fallow-editor-placeholders' that silences the 'editor placeholder in source file' error. This is useful for an IDE like Xcode as we don't want to display those errors in live issues. rdar://31581400 Differential Revision: https://reviews.llvm.org/D32081 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@300667 91177308-0d34-0410-b5e6-96231b3b80d8
* [modules-ts] Fold together -x c++ and -x c++-module at -cc1 level.Richard Smith2017-04-181-2/+0
| | | | | | | | | | | | | | The driver needs to know whether it's building a module interface or implementation unit because it affects which outputs it produces and how it builds the command pipeline. But the frontend doesn't need to know and should not care: all it needs to know is what action it is being asked to perform on the input. (This is in preparation for permitting -emit-obj to be used on a module interface unit to produce object code without going via a "full" PCM file.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@300611 91177308-0d34-0410-b5e6-96231b3b80d8

We use the same syntax and semantics as the sanitizer blacklists files in the implementation. As implemented, we respect the attributes that are already defined in the source file (i.e. those that have the [[clang::xray_{always,never}_instrument]] attributes) before applying the always/never instrument lists.

* Use FPContractModeKind universallyAdam Nemet2017-03-291-17/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | FPContractModeKind is the codegen option flag which is already ternary (off, on, fast). This makes it universally the type for the contractable info across the front-end: * In FPOptions (i.e. in the Sema + in the expression nodes). * In LangOpts::DefaultFPContractMode which is the option that initializes FPOptions in the Sema. Another way to look at this change is that before fp-contractable on/off were the only states handled to the front-end: * For "on", FMA folding was performed by the front-end * For "fast", we simply forwarded the flag to TargetOptions to handle it in LLVM Now off/on/fast are all exposed because for fast we will generate fast-math-flags during CodeGen. This is toward moving fp-contraction=fast from an LLVM TargetOption to a FastMathFlag in order to fix PR25721. --- This is a recommit of r299027 with an adjustment to the test CodeGenCUDA/fp-contract.cu. The test assumed that even though -ffp-contract=on is passed FE-based folding of FMA won't happen. This is obviously wrong since the user is asking for this explicitly with the option. CUDA is different that -ffp-contract=fast is on by default. The test used to "work" because contract=fast and contract=on were maintained separately and we didn't fold in the FE because contract=fast was on due to the target-default. This patch consolidates the contract=on/fast/off state into a ternary state hence the change in behavior. --- Differential Revision: https://reviews.llvm.org/D31167 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@299033 91177308-0d34-0410-b5e6-96231b3b80d8

* Modules: Use hash of PCM content for SIGNATUREDuncan P. N. Exon Smith2017-03-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Change ASTFileSignature from a random 32-bit number to the hash of the PCM content. - Move definition ASTFileSignature to Basic/Module.h so Module and ASTSourceDescriptor can use it. - Change the signature from uint64_t to std::array<uint32_t,5>. - Stop using (saving/reading) the size and modification time of PCM files when there is a valid SIGNATURE. - Add UNHASHED_CONTROL_BLOCK, and use it to store the SIGNATURE record and other records that shouldn't affect the hash. Because implicit modules reuses the same file for multiple levels of -Werror, this includes DIAGNOSTIC_OPTIONS and DIAG_PRAGMA_MAPPINGS. This helps to solve a PCH + implicit Modules dependency issue: PCH files are handled by the external build system, whereas implicit modules are handled by internal compiler build system. This prevents invalidating a PCH when the compiler overwrites a PCM file with the same content (modulo the diagnostic differences).

* [CodeGen] [CUDA] Add the ability set default attrs on functions in linked ↵Justin Lebar2017-01-251-5/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | modules. Summary: Now when you ask clang to link in a bitcode module, you can tell it to set attributes on that module's functions to match what we would have set if we'd emitted those functions ourselves. This is particularly important for fast-math attributes in CUDA compilations. Each CUDA compilation links in libdevice, a bitcode library provided by nvidia as part of the CUDA distribution. Without this patch, if we have a user-function F that is compiled with -ffast-math that calls a function G from libdevice, F will have the unsafe-fp-math=true (etc.) attributes, but G will have no attributes. Since F calls G, the inliner will merge G's attributes into F's. It considers the lack of an unsafe-fp-math=true attribute on G to be tantamount to unsafe-fp-math=false, so it "merges" these by setting unsafe-fp-math=false on F. This then continues up the call graph, until every function that (transitively) calls something in libdevice gets unsafe-fp-math=false set, thus disabling fastmath in almost all CUDA code.

Unlike the traditional debugging purpose, sample pgo needs more accurate debug info to represent the profile. We add -femit-accurate-debug-info for this purpose. It can be combined with all debugging modes (-g, -gmlt, etc). It makes sure that the following pieces of info is always emitted: * start line of all subprograms * linkage name of all subprograms * standalone subprograms (functions that has neither inlined nor been inlined) The impact on speccpu2006 binary size (size increase comparing with -g0 binary, also includes data for -g binary, which does not change with this patch): -gmlt(orig) -gmlt(patched) -g 433.milc 4.68% 5.40% 19.73% 444.namd 8.45% 8.93% 45.99% 447.dealII 97.43% 115.21% 374.89% 450.soplex 27.75% 31.88% 126.04% 453.povray 21.81% 26.16% 92.03% 470.lbm 0.60% 0.67% 1.96% 482.sphinx3 5.77% 6.47% 26.17% 400.perlbench 17.81% 19.43% 73.08% 401.bzip2 3.73% 3.92% 12.18% 403.gcc 31.75% 34.48% 122.75% 429.mcf 0.78% 0.88% 3.89% 445.gobmk 6.08% 7.92% 42.27% 456.hmmer 10.36% 11.25% 35.23% 458.sjeng 5.08% 5.42% 14.36% 462.libquantum 1.71% 1.96% 6.36% 464.h264ref 15.61% 16.56% 43.92% 471.omnetpp 11.93% 15.84% 60.09% 473.astar 3.11% 3.69% 14.18% 483.xalancbmk 56.29% 81.63% 353.22% geomean 15.60% 18.30% 57.81% Debug info size change for -gmlt binary with this patch: 433.milc 13.46% 444.namd 5.35% 447.dealII 18.21% 450.soplex 14.68% 453.povray 19.65% 470.lbm 6.03% 482.sphinx3 11.21% 400.perlbench 8.91% 401.bzip2 4.41% 403.gcc 8.56% 429.mcf 8.24% 445.gobmk 29.47% 456.hmmer 8.19% 458.sjeng 6.05% 462.libquantum 11.23% 464.h264ref 5.93% 471.omnetpp 31.89% 473.astar 16.20% 483.xalancbmk 44.62% geomean 16.83% Reviewers: davidxl, andreadb, rob.lougher, dblaikie, echristo Reviewed By: dblaikie, echristo Subscribers: hfinkel, rob.lougher, andreadb, gbedwell, cfe-commits, probinson, llvm-commits, mehdi_amini Differential Revision: https://reviews.llvm.org/D25435 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@292458 91177308-0d34-0410-b5e6-96231b3b80d8
* Move vtable type metadata emission behind a cc1-level flag.Peter Collingbourne2017-01-181-0/+1
| | | | | | | | | | | | | In ThinLTO mode, type metadata will require the module to be written as a multi-module bitcode file, which is currently incompatible with the Darwin linker. It is also useful to be able to enable or disable multi-module bitcode for testing purposes. This introduces a cc1-level flag, -f{,no-}lto-unit, which is used by the driver to enable multi-module bitcode on all but Darwin+ThinLTO, and can also be used to enable/disable the feature manually.
