* Fix -save-temp when using objc-arc, sanitizer and profilingSteven Wu2015-07-171-0/+3
| | | | | | | | | | | | 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/+1
| | | | | | | | | | | | | | | | | | The patch is the same except for the addition of a new test for the issue that required reverting the dependent llvm commit. --Original Commit Message-- Pass down the -flto option to the -cc1 job, and from there into the CodeGenOptions and onto the PassManagerBuilder. This enables gating the new EliminateAvailableExternally module pass on whether we are preparing for LTO. If we are preparing for LTO (e.g. a -flto -c compile), the new pass is not included as we want to preserve available externally functions for possible link time inlining. llvm-svn: 241467

* [ASan] Initial support for Kernel AddressSanitizerAlexander Potapenko2015-06-191-2/+15
| | | | | | | | | This patch adds initial support for the -fsanitize=kernel-address flag to Clang. Right now it's quite restricted: only out-of-line instrumentation is supported, globals are not instrumented, some GCC kasan flags are not supported. Using this patch I am able to build and boot the KASan tree with LLVMLinux patches from github.com/ramosian-glider/kasan/tree/kasan_llvmlinux. To disable KASan instrumentation for a certain function attribute((no_sanitize("kernel-address"))) can be used. llvm-svn: 240131

| | | | | | | | | | | | | | | | | | | The 1st and 2nd tries to land this (r238055, r238851) were reverted due to bot failures caused by the LLVM part of the patch.

* [SanitizerCoverage] Implement user-friendly -fsanitize-coverage= flags.Alexey Samsonov2015-05-071-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Possible coverage levels are: * -fsanitize-coverage=func - function-level coverage * -fsanitize-coverage=bb - basic-block-level coverage * -fsanitize-coverage=edge - edge-level coverage Extra features are: * -fsanitize-coverage=indirect-calls - coverage for indirect calls * -fsanitize-coverage=trace-bb - tracing for basic blocks * -fsanitize-coverage=trace-cmp - tracing for cmp instructions * -fsanitize-coverage=8bit-counters - frequency counters Levels and features can be combined in comma-separated list, and can be disabled by subsequent -fno-sanitize-coverage= flags, e.g.: -fsanitize-coverage=bb,trace-bb,8bit-counters -fno-sanitize-coverage=trace-bb is equivalient to: -fsanitize-coverage=bb,8bit-counters Original semantics of -fsanitize-coverage flag is preserved: * -fsanitize-coverage=0 disables the coverage * -fsanitize-coverage=1 is a synonym for -fsanitize-coverage=func * -fsanitize-coverage=2 is a synonym for -fsanitize-coverage=bb * -fsanitize-coverage=3 is a synonym for -fsanitize-coverage=edge * -fsanitize-coverage=4 is a synonym for -fsanitize-coverage=edge,indirect-calls Driver tries to diagnose invalid flag usage, in particular: * At most one level (func,bb,edge) must be specified. * "trace-bb" and "8bit-counters" features require some level to be specified.

* Fix -fobjc-arc doesn't work with -save-tempsSteven Wu2015-05-021-2/+1
| | | | | | | | | | The underlying problem is that there is currently no way to run ObjCARCContract from llvm bitcode which is required by ObjC ARC. This fix the problem by always enable ObjCARCContract pass if optimization is enabled. The ObjCARC Contract pass has almost no overhead on code that is not using ARC. llvm-svn: 236372
* InstrProf: Support for setting profile output from command lineJustin Bogner2015-04-301-0/+1
| | | | | | | | | | | | | | | | This change is the third of 3 patches to add support for specifying the profile output from the command line via -fprofile-instr-generate=<path>, where the specified output path/file will be overridden by the LLVM_PROFILE_FILE environment variable. This patch adds the necessary support to the clang frontend, and adds a new test. The compiler-rt and llvm parts are r236055 and r236288, respectively. Patch by Teresa Johnson. Thanks! llvm-svn: 236289

* uselistorder: -mllvm -preserve-ll-use-list-order => -emit-llvm-uselistsDuncan P. N. Exon Smith2015-04-151-1/+2
| | | | | | | | | Follow up to r234962, start respecting `-emit-llvm-uselists even for LLVM assembly. Note that the driver never passes this flag; this is just a interface convenience/consistency for those using `-cc1` directly. This required LLVM r234969 (and predecessors). llvm-svn: 234970
* uselistorder: -mllvm -preserve-bc-use-list-order => -emit-llvm-uselistsDuncan P. N. Exon Smith2015-04-151-1/+1
| | | | | | | | | | | | | | | Stop relying on `cl::opt` to pass along the driver's decision to preserve use-lists. Create a new `-cc1` option called `-emit-llvm-uselists` that does the right thing (when -emit-llvm-bc). Note that despite its generic name, it *doesn't* do the right thing when -emit-llvm (LLVM assembly) yet. I'll hook that up soon. This doesn't really change the behaviour of the driver. The default is still to preserve use-lists for `clang -emit-llvm` and `clang -save-temps`, and nothing else. But it stops relying on global state (and also is a nicer interface for hackers using `clang -cc1`). llvm-svn: 234962
* uselistorder: Update for LLVM API change in r234959Duncan P. N. Exon Smith2015-04-151-1/+3
| | | | | | | | Now that `addBitcodeWriterPass()` requires an explicit bit to preserve use-list order, send it in from `clang`. It looks like I'll be able to push this up to the `-cc1` options. llvm-svn: 234960
* Use raw_pwrite_stream in clang.Rafael Espindola2015-04-141-7/+9

| | | | | | | | Follow-up to r234666. With this, the -m[no-]global-merge options have the expected behavior. Previously, -mglobal-merge was ignored, and there was no way of enabling the optimization. llvm-svn: 234668

* GCOV: Expose the -coverage-exit-block-before-body flag in clang -cc1Justin Bogner2015-03-161-0/+1
| | | | | | | | | This exposes the optional exit block placement logic from r232438 as a clang -cc1 option. There is a test on the llvm side, but there isn't really a way to inspect the gcov options from clang to test it here as well. llvm-svn: 232439

* [PM] Move away from the old llvm/PassManager.h header and its usingChandler Carruth2015-02-131-22/+22
| | | | | | | | | | | | declarations and just use the legacy namespace qualifier in this file and the permanent header name. The old wrapper header is going away to make LLVM's build more modular, and without updating Clang I can't easily start to add usage of the new pass manager to Clang. This should make it more clear in the code which set of types is doing what. llvm-svn: 229090
* Allow to specify multiple -fsanitize-blacklist= arguments.Alexey Samsonov2015-02-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Summary: Allow user to provide multiple blacklists by passing several -fsanitize-blacklist= options. These options now don't override default blacklist from Clang resource directory, which is always applied (which fixes PR22431). -fno-sanitize-blacklist option now disables all blacklists that were specified earlier in the command line (including the default one).

* [multiversion] Update Clang for the API change in LLVM r227731.Chandler Carruth2015-02-011-6/+9
| | | | | | | | | | | This moves all of the PassManager <-> Target communication to use the new pass manager's TargetIRAnalysis even with the old pass manager. See the LLVM commit for some of why things are moving in this direction, but the short version is that this will enable us to create per-function TargetTransformInfo objects that have correct subtarget information for that function. llvm-svn: 227732
