2013-02-18Unify some code. No functional change.Eric Christopher
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175409 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-10Use -mno-implicit-float by default for kernel/kext code. <rdar://13177960>Bob Wilson
Apple's kernel engineers have been expecting this behavior even though we've never implemented it before, as far as I can tell. In recent months, clang has gotten better at using vector instructions to optimize memcpy-like operations, and that has exposed problems when vector/floating-point instructions are used in kexts that don't support that. This behavior also matches what Apple's GCC did for PowerPC targets. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174838 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-10Recognize -mno-implicit-float option for x86 as well as ARM. <rdar://13180731>Bob Wilson
For x86 targets, we've been using the -msoft-float option to control passing the no-implicit-float option to cc1. Since the -mno-implicit-float option is now accepted by the driver, this just makes it work for x86 the same as it does for ARM targets. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174836 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-07Introduce -fmodules-ignore-macro=NNN to ignore a macro when building/loading ↵Douglas Gregor
modules. The use of this flag enables a modules optimization where a given set of macros can be labeled as "ignored" by the modules system. Definitions of those macros will be completely ignored when building the module hash and will be stripped when actually building modules. The overall effect is that this flag can be used to drastically reduce the number of Eventually, we'll want modules to tell us what set of macros they respond to (the "configuration macros"), and anything not in that set will be excluded. However, that requires a lot of per-module information that must be accurate, whereas this option can be used more readily. Fixes the rest of <rdar://problem/13165109>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174560 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-01Enable -fno-altivec, -mno-altivec for PowerPC.Bill Schmidt
Introduces these negation forms explicitly and uses them to control a new "altivec" target feature for PowerPC. This allows avoiding generating Altivec instructions on processors that support Altivec. The new test case verifies that the Altivec "lvx" instruction is not used when -fno-altivec is present on the command line. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174140 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-31Add support for AArch64 target.Tim Northover
In cooperation with the LLVM patch, this should implement all scalar front-end parts of the C and C++ ABIs for AArch64. This patch excludes the NEON support also reviewed due to an outbreak of batshit insanity in our legal department. That will be committed soon bringing the changes to precisely what has been approved. Further reviews would be gratefully received. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174055 91177308-0d34-0410-b5e6-96231b3b80d8

minor cleanup. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173852 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-29[ubsan] Implement the -fcatch-undefined-behavior flag using a trappingChad Rosier
implementation; this is much more inline with the original implementation (i.e., pre-ubsan) and does not require run-time library support. The trapping implementation can be invoked using either '-fcatch-undefined-behavior' or '-fsanitize=undefined-trap -fsanitize-undefined-trap-on-error', with the latter being preferred. Eventually, the -fcatch-undefined-behavior' flag will be removed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173848 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-29[driver] Refactor the driver so that a failing commands doesn't preventChad Rosier
subsequent commands from being executed. The diagnostics generation isn't designed for this use case, so add a note to fix this in the very near future. For now, just generated the diagnostics for the first failing command. Part of rdar://12984531 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173825 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-22[ASan] Link with the dynamic runtime on OS XAlexander Potapenko
This patch changes the behavior of the -fsanitize=address flag, making it use the dynamic runtime library (libclang_rt.asan_osx_dynamic.dylib) instead of the static one. It also drops the CoreFoundation dependency, since the dynamic runtime doesn't need it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173135 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-17We want the dwarf AT_producer for assembly source files to match clang'sKevin Enderby
AT_producer. Which includes clang's version information so we can tell which version of the compiler was used. This is second of the two steps to allow us to do this. The first was a change to llvm-mc with revision 172630 to provide a method to set the AT_producer string. This second step has the clang driver passing the value of getClangFullVersion() via the new flag -dwarf-debug-producer when invoking the integrated assembler on assembly source files. Then using the new setDwarfDebugProducer() method to set the AT_producer string. rdar://12888242 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172758 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-17Add initial rough support for synthesizing linker options when passedChandler Carruth
-fopenmp in the link step on Linux. There is probably more tweaking that will need to take place to get good support for linking the relevant libraries on all Linux distributions and/or on other platforms, but this get's the ball moving and allows Clang to build programs which contain OpenMP pragmas that can be safely ignored by a compiler that doesn't implement them, and yet makes direct calls into the OpenMP runtime. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172715 91177308-0d34-0410-b5e6-96231b3b80d8
