2016-05-24[Sparc] Add software float option -msoft-floatJacob Baungard Hansen1-15/+59
Summary: Following patch D19265 which enable software floating point support in the Sparc backend, this patch enables the option to be enabled in the front-end using the -msoft-float option. The user should ensure a library (such as the builtins from Compiler-RT) that includes the software floating point routines is provided.

2016-05-22Driver: sink getLinuxDynamicLoader into the ToolchainSaleem Abdulrasool1-70/+1
The parameter already requires the toolchain, sink the method into the class. This also enables the use of the distro detection logic which will be needed to support Exherbo's multiarch approach. llvm-svn: 270352
2016-05-22Driver: simplify getDynameLinkerSaleem Abdulrasool1-47/+49
Convert the cascading if/else to a switch. This makes it easier to follow the logic. Minor difference is that we no longer default to x86_64 but rather to the architecture specified by the architecture. llvm-svn: 270351

2016-05-13Get default -fms-compatibility-version from cl.exe's versionAdrian McCarthy1-4/+10
-fms-compatibility-version was defaulting to 18 (VS 2013), which is a pain if your environment is pointing to version 19 (VS 2015) libraries. If cl.exe can be found, this patch uses its version number as the default instead. It re-uses the existing code to find the Visual Studio binaries folder and WinAPI methods to check its version. You can still explicitly specify a compatibility version on the command line. If you don't have cl.exe, this should be a no-op and you'll get the old default of 18. This affected the tests, which assumed that if you didn't specific a version, that it would default to 18, but this won't be true for all machines. So a couple test cases had to be eliminated and a couple others had to be tweaked to allow for various outputs.

2016-05-12[ubsan] Add -fsanitize-undefined-strip-path-components=NFilipe Cabecinhas1-0/+4
Summary: This option allows the user to control how much of the file name is emitted by UBSan. Tuning this option allows one to save space in the resulting binary, which is helpful for restricted execution environments. With a positive N, UBSan skips the first N path components. With a negative N, UBSan only keeps the last N path components. Reviewers: rsmith Subscribers: cfe-commits Differential Revision: http://reviews.llvm.org/D19666 llvm-svn: 269309

Summary: Teach clang to embed bitcode inside bitcode.

2016-05-02Revert "[Driver] Quote clang full version in dwarf producer when invoking cc1as"Bruno Cardoso Lopes1-2/+1
This reverts commit r264813 / 6484b95d634f53dd929c75265ef3c4decf397584. While using it in the shell is fine, this a problem when cc1as is invoked directly by the driver because single quoting the clang full version makes cc1as write out the version with the quotes in the final binary.

2016-04-27Rework interface for bitset-using features to use a notion of LTO visibility.Peter Collingbourne1-26/+13
Bitsets, and the compiler features they rely on (vtable opt, CFI), only have visibility within the LTO'd part of the linkage unit. Therefore, only enable these features for classes with hidden LTO visibility. This notion is based on object file visibility or (on Windows) dllimport/dllexport attributes. We provide the [[clang::lto_visibility_public]] attribute to override the compiler's LTO visibility inference in cases where the class is defined in the non-LTO'd part of the linkage unit, or where the ABI supports calling classes derived from abstract base classes with hidden visibility in other linkage units (e.g. COM on Windows). If the cross-DSO CFI mode is enabled, bitset checks are emitted even for classes with public LTO visibility, as that mode uses a separate mechanism to cause bitsets to be exported. This mechanism replaces the whole-program-vtables blacklist, so remove the -fwhole-program-vtables-blacklist flag. Because __declspec(uuid()) now implies [[clang::lto_visibility_public]], the support for the special attr:uuid blacklist entry is removed.

2016-04-06Enable PIE for CloudABI.Ed Schouten1-0/+6
As we're currently working on making CloudABI executables easier to emulate in userspace (e.g., on OS X and Windows), it makes a whole lot of sense to build these using PIE. By using PIE, they can simply be loaded into the existing process address space without clashes. PIE support got added to CloudABI's C library and seems to work pretty well. CloudABI does not make use of an ld.so, so the binary's _start() has all the logic in it to do the relocations. Now that all but one bug in LLD relating to PIE support have been squashed (and a patch for that is already in code review), I'd like to go ahead and force the use of PIE for Clang 3.9. When released, we'll also switch over to using LLD exclusively. llvm-svn: 265546

Most things even work; see the included FIXMEs for things that need polishing. Also don't warn about unused flags for the `/Yuh2.h /FIh1.h /FIh2.h`. The common case is that the pch was built with `/Ych2.h /FIh1.h /FIh2.h`, so h1.h is in the PCH, and we shouldn't warn about /FIh1.h not having an effect. (If we wanted to get fancy, we could store the list of -include flags in the pch and then check that it matches later on.) llvm-svn: 264178

2016-03-16Convert some ObjC msgSends to runtime calls.Pete Cooper1-0/+12
It is faster to directly call the ObjC runtime for methods such as retain/release instead of sending a message to those functions. This patch adds support for converting messages to retain/release/alloc/autorelease to their equivalent runtime calls. Tests included for the positive case of applying this transformation, negative tests that we ensure we only convert "alloc" to objc_alloc, not "alloc2", and also a driver test to ensure we enable this only for supported runtime versions.
