* Revert "Clang support for -flto=thin." (bot failures)Teresa Johnson2015-10-151-3/+1
| | | | | | | | | | | Rolling this back for now since there are a couple of bot failures on the new tests I added, and I won't have a chance to look at them in detail until later this afternoon. I think the new tests need some restrictions on having the gold plugin available. This reverts commit r250398. llvm-svn: 250402
* Clang support for -flto=thin.Teresa Johnson2015-10-151-1/+3
| | | | | | | | | | | | | | | | | | | Summary: Add clang support for -flto=thin option, which is used to set the EmitFunctionSummary code gen option on compiles. Add -flto=full as an alias to the existing -flto. Add tests to check for proper overriding of -flto variants on the command line, and convert grep tests to FileCheck.

* Support Debug Info path remappingSaleem Abdulrasool2015-10-121-0/+3
| | | | | | | | | | | | | | | | Add support for the `-fdebug-prefix-map=` option as in GCC. The syntax is `-fdebug-prefix-map=OLD=NEW`. When compiling files from a path beginning with OLD, change the debug info to indicate the path as start with NEW. This is particularly helpful if you are preprocessing in one path and compiling in another (e.g. for a build cluster with distcc). Note that the linearity of the implementation is not as terrible as it may seem. This is normally done once per file with an expectation that the map will be small (1-2) entries, making this roughly linear in the number of input paths. Addresses PR24619. llvm-svn: 250094
* Stop messing with the 'g' group of options in CompilerInvocation.Douglas Katzman2015-10-081-29/+9
| | | | | | | | | | | | | | | | 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

* Add -f[no-]declspec to control recognition of __declspec as a keywordSaleem Abdulrasool2015-10-041-0/+11
| | | | | | | | | | | | | | | In versions of clang prior to r238238, __declspec was recognized as a keyword in all modes. It was then changed to only be enabled when Microsoft or Borland extensions were enabled (and for CUDA, as a temporary measure). There is a desire to support __declspec in Playstation code, and possibly other environments. This commit adds a command-line switch to allow explicit enabling/disabling of the recognition of __declspec as a keyword. Recognition is enabled by default in Microsoft, Borland, CUDA, and PS4 environments, and disabled in all other environments. Patch by Warren Ristow! llvm-svn: 249279

* [CUDA] Allow function overloads in CUDA based on host/device attributes.Artem Belevich2015-09-221-0/+3
| | | | | | | | | | | | | | | | | | | The patch makes it possible to parse CUDA files that contain host/device functions with identical signatures, but different attributes without having to physically split source into host-only and device-only parts. This change is needed in order to parse CUDA header files that have a lot of name clashes with standard include files.

* Add sanitizer blacklists to the rules generated with -M/-MM/-MD/-MMD.Ivan Krasin2015-08-131-0/+4
| | | | | | | | | | | | | | | | | | | Summary: Clang sanitizers, such as AddressSanitizer, ThreadSanitizer, MemorySanitizer, Control Flow Integrity and others, use blacklists to specify which types / functions should not be instrumented to avoid false positives or suppress known failures. This change adds the blacklist filenames to the list of dependencies of the rules, generated with -M/-MM/-MD/-MMD. This lets CMake/Ninja recognize that certain C/C++/ObjC files need to be recompiled (if a blacklist is updated).

* Add support for System z vector language extensionsUlrich Weigand2015-07-301-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The z13 vector facility has an associated language extension, closely modeled on AltiVec/VSX. The main differences are: - vector long, vector float and vector pixel are not supported - vector long long and vector double are supported (like VSX) - comparison operators return a vector rather than a scalar integer - shift operators behave like the OpenCL shift operators - vector bool is only supported as argument to certain operators; some operators allow mixing a bool with a non-bool vector This patch adds clang support for the extension. It is closely modelled on the AltiVec support. Similarly to the -faltivec option, there's a new -fzvector option to enable the extensions (as well as an -mzvector alias for compatibility with GCC). There's also a separate LangOpt. The extension as implemented here is intended to be compatible with the -mzvector extension recently implemented by GCC. Based on a patch by Richard Sandiford.

* Fix -save-temp when using objc-arc, sanitizer and profilingSteven Wu2015-07-171-1/+11
| | | | | | | | | | | | Currently, -save-temp will cause ObjCARC optimization to be dropped, sanitizer pass to run early in the pipeline, and profiling instrumentation to run twice. Fix the issue by properly disable all passes in the optimization pipeline when generating bitcode output and parse some of the Language Options even when the input is bitcode so the passes can be setup correctly. llvm-svn: 242565

* Resubmit "Pass down the -flto option to the -cc1 job" (r239481)Teresa Johnson2015-07-061-0/+2

This enables gating the new EliminateAvailableExternally module pass on whether we are preparing for LTO.

* Introduce -fsanitize-trap= flag.Peter Collingbourne2015-06-181-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | This flag controls whether a given sanitizer traps upon detecting an error. It currently only supports UBSan. The existing flag -fsanitize-undefined-trap-on-error has been made an alias of -fsanitize-trap=undefined. This change also cleans up some awkward behavior around the combination of -fsanitize-trap=undefined and -fsanitize=undefined. Previously we would reject command lines containing the combination of these two flags, as -fsanitize=vptr is not compatible with trapping. This required the creation of -fsanitize=undefined-trap, which excluded -fsanitize=vptr (and -fsanitize=function, but this seems like an oversight). Now, -fsanitize=undefined is an alias for -fsanitize=undefined-trap, and if -fsanitize-trap=undefined is specified, we treat -fsanitize=vptr as an "unsupported" flag, which means that we error out if the flag is specified explicitly, but implicitly disable it if the flag was implied by -fsanitize=undefined.

* [modules] Simplify -cc1 interface for enabling implicit module maps.Richard Smith2015-06-161-4/+1
| | | | | | | | | | | | | We used to have a flag to enable module maps, and two more flags to enable implicit module maps. This is all redundant; we don't need any flag for enabling module maps in the abstract, and we don't usually have -fno- flags for -cc1. We now have just a single flag, -fimplicit-module-maps, that enables implicitly searching the file system for module map files and loading them. The driver interface is unchanged for now. We should probably rename -fmodule-maps to -fimplicit-module-maps at some point. llvm-svn: 239789
* Add `-verify-ignore-unexpected` option to ignore unexpected diagnostics in ↵Eric Fiselier2015-06-131-1/+31
| | | | | | | | | | | | | | | | | | | | | VerifyDiagnosticsConsumer Summary: The goal of this patch is to make `-verify` easier to use when testing libc++. The `notes` attached to compile error diagnostics are numerous and relatively unstable when they reference libc++ header internals. This patch allows libc++ to write stable compilation failure tests by allowing unexpected diagnostic messages to be ignored where they are not relevant. This patch adds a new CC1 flag called `-verify-ignore-unexpected`. `-verify-ignore-unexpected` tells `VerifyDiagnosticsConsumer` to ignore *all* unexpected diagnostic messages. `-verify-ignore-unexpected=<LevelList>` can be used to only ignore certain diagnostic levels. `<LevelList>` is a comma separated list of diagnostic levels to ignore. The supported levels are `note`, `remark`, `warning` and `error`.
