* Allows Clang to use LLVM's fixes-x18 optionRenato Golin2015-01-251-0/+5
| | | | | | | | | | | | | This patch allows clang to have llvm reserve the x18 platform register on AArch64. FreeBSD will use this in the kernel for per-cpu data but has no need to reserve this register in userland so will need this flag to reserve it. This uses llvm r226664 to allow this register to be reserved. Patch by Andrew Turner. llvm-svn: 227062

* Process the -fno-signed-zeros optimization flag (PR20870)Sanjay Patel2015-01-231-0/+2
| | | | | | | | | | | | | | | | | | The driver currently accepts but ignores the -fno-signed-zeros flag. This patch passes the flag through and enables 'nsz' fast-math-flag generation in IR. The existing OpenCL flag for the same functionality is made into an alias here. It may be removed in a subsequent patch.

* Insert random noops to increase security against ROP attacks (clang)JF Bastien2015-01-141-0/+11
| | | | | | | | | | | | | | | | | | | | A pass that adds random noops to X86 binaries to introduce diversity with the goal of increasing security against most return-oriented programming attacks. Command line options: -noop-insertion // Enable noop insertion. -noop-insertion-percentage=X // X% of assembly instructions will have a noop prepended (default: 50%, requires -noop-insertion) -max-noops-per-instruction=X // Randomly generate X noops per instruction. ie. roll the dice X times with probability set above (default: 1). This doesn't guarantee X noop instructions. In addition, the following 'quick switch' in clang enables basic diversity using default settings (currently: noop insertion and schedule randomization; it is intended to be extended in the future). -fdiversify This is the clang part of the patch. llvm part: D3392 http://reviews.llvm.org/D3393 Patch by Stephen Crane (@rinon) llvm-svn: 225910
* Reimplement -fsanitize-recover family of flags.Alexey Samsonov2015-01-121-7/+45
| | | | | | | | | | | | | | | | | | | | | | | | Introduce the following -fsanitize-recover flags: - -fsanitize-recover=<list>: Enable recovery for selected checks or group of checks. It is forbidden to explicitly list unrecoverable sanitizers here (that is, "address", "unreachable", "return"). - -fno-sanitize-recover=<list>: Disable recovery for selected checks or group of checks. - -f(no-)?sanitize-recover is now a synonym for -f(no-)?sanitize-recover=undefined,integer and will soon be deprecated. These flags are parsed left to right, and mask of "recoverable" sanitizer is updated accordingly, much like what we do for -fsanitize= flags. -fsanitize= and -fsanitize-recover= flag families are independent. CodeGen change: If there is a single UBSan handler function, responsible for implementing multiple checks, which have different recoverable setting, then we emit two handler calls instead of one: the first one for the set of "unrecoverable" checks, another one - for set of "recoverable" checks. If all checks implemented by a handler have the same recoverability setting, then the generated code will be the same. llvm-svn: 225719

| | | | | | | | | | Allow blessed access to the symbol rewriter from the driver. Although the symbol rewriter could be invoked through tools like opt and llc, it would not accessible from the frontend. This allows us to read the rewrite map files in the frontend rather than the backend and enable symbol rewriting for actually performing the symbol interpositioning. llvm-svn: 225504

* Driver: honour the clang-cl behaviour on ARM as wellSaleem Abdulrasool2015-01-021-3/+4
| | | | | | | | | | Unfortunately, MSVC does not indicate to the driver what target is being used. This means that we cannot correctly select the target architecture for the clang_rt component. This breaks down when targeting windows with the clang driver as opposed to the clang-cl driver. This should fix the native ARM buildbot tests. llvm-svn: 225089
* Driver: reuse getCompilerRT in place of addSanitizerRTWindowsSaleem Abdulrasool2015-01-021-16/+16
| | | | | | | | | | | The logic for addSanitizerRTWindows was performing the same logical operation as getCompilerRT, which was previously fully generalised for Linux and Windows. This avoids having a duplication of the logic for building up the name of a clang_rt component. This change does move the current limitation for Windows into getArchNameForCompilerRTLib, where it is assumed that the architecture for Windows is always i386. llvm-svn: 225087
* Driver: unify compiler-rt component selectionSaleem Abdulrasool2014-12-301-37/+28
| | | | | | | | | | | | | Unify the component handling for compiler-rt. The components are regularly named, built up from: ${LIBRARY_PREFIX}clang_rt.${component}-${arch}[-${environment}]${LIBRARY_SUFFIX} Unify the handling for all the various components, into a single path to link against the various components in a number of places. This reduces duplication of the clang_rt library name construction logic. llvm-svn: 225013

| | | | | | | | Unlike Unices, Windows does not use a library prefix. Use the traditional naming scheme even for Windows itanium environments. This makes the builtins behave more like the sanitisers as well. llvm-svn: 224996

* [multilib] Teach Clang's code about multilib by threadingChandler Carruth2014-12-291-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | a CLANG_LIBDIR_SUFFIX down from the build system and using that as part of the default resource dir computation. Without this, essentially nothing that uses the clang driver works when building clang with a libdir suffix. This is probably the single biggest missing piece of support for multilib as without this people could hack clang to end up installed in the correct location, but it would then fail to find its own basic resources. I know of at least one distro that has some variation on this patch to hack around this; hopefully they'll be able to use the libdir suffix functionality directly as the rest of these bits land. This required fixing a copy of the code to compute Clang's resource directory that is buried inside of the frontend (!!!). It had bitrotted significantly relative to the driver code. I've made it essentially a clone of the driver code in order to keep tests (which use cc1 heavily) passing. This copy should probably just be removed and the frontend taught to always rely on an explicit resource directory from the driver, but that is a much more invasive change for another day. I've also updated one test which actually encoded the resource directory in its checked output to tolerate multilib suffixes. Note that this relies on a prior LLVM commit to add a stub to the autoconf build system for this variable. llvm-svn: 224924
* Add driver flags -ftrigraphs, -fno-trigraphs.Nico Weber2014-12-231-2/+5
| | | | | | | | | | | | | | | | | -trigraphs is now an alias for -ftrigraphs. -fno-trigraphs makes it possible to explicitly disable trigraphs, which couldn't be done before. clang -std=c++11 -fno-trigraphs now builds without GNU extensions, but with trigraphs disabled. Previously, trigraphs were only disabled in GNU modes or with -std=c++1z. Make the new -f flags the cc1 interface too. This requires changing -trigraphs to -ftrigraphs in a few cc1 tests. Related to PR21974. llvm-svn: 224790
* Reapply "Change -save-temps to emit unoptimized bitcode files."Bob Wilson2014-12-217-17/+76
| | | | | | | | | | | | | | | | | | | | | | | | This reapplies r224503 along with a fix for compiling Fortran by having the clang driver invoke gcc (see r224546, where it was reverted). I have added a testcase for that as well. Original commit message: It is often convenient to use -save-temps to collect the intermediate results of a compilation, e.g., when triaging a bug report. Besides the temporary files for preprocessed source and assembly code, this adds the unoptimized bitcode files as well. This adds a new BackendJobAction, which is mostly mechanical, to run after the CompileJobAction. When not using -save-temps, the BackendJobAction is combined into one job with the CompileJobAction, similar to the way the integrated assembler is handled. I've implemented this entirely as a driver change, so under the hood, it is just using -disable-llvm-optzns to get the unoptimized bitcode.

"-fsanitize=all" option makes no sense, and will produce an error. This group can also be useful when we add "-fsanitize-recover=<list>" options (patch in http://reviews.llvm.org/D6302), as it would allow to conveniently enable/disable recovery for all specified sanitizers.
