2013-03-20Fix redundant comparison in gcc::Common::ConstructJob.Hans Wennborg
We were checking "Arch == llvm::Triple::x86_64 || Arch == llvm::Triple::x86_64", but the rhs should actually check for powerpc64. Found while experimenting with a potential new Clang warning. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177496 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-12Revert "Disallow using -fmodules with -no-integrated-as."Ted Kremenek
Per comment from Benjamin Kramer, this isn't portable (yet). I'll come up with a better fix. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176876 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-11Disallow using -fmodules with -no-integrated-as.Ted Kremenek
Modules enables features such as auto-linking, and we simply do not want to support a matrix of subtly enabled/disabled features depending on whether or not a user is using the integrated assembler. It isn't clear if this is the best place to do this check. For one thing, these kind of errors are not caught by the serialized diagnostics.

2013-03-07Add flags for additional control over coverage generation. Pick the versionNick Lewycky
string to be emitted, and two properties about the files themselves. Use $PWD to absolut-ify the path to the coverage file. Yes, this is what GCC does. Reverts my own r175706. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176617 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-04Check for warnings in a bunch of the linker invocations, and add oneChandler Carruth
with both -static-libgcc and -static on the commandline. Fix a warning in the latter case due to a backwards short circuiting || operator in the driver. No real functionality changed here, just allows the driver to properly consume -static-libgcc when -static is also specified. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176429 91177308-0d34-0410-b5e6-96231b3b80d8

In order to make the testcase a bit more efficient allow the filename to go through compilation for compile and not assemble jobs and turn off the extract for cases where we don't create an object. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175935 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-22Driver: Pass down the -march setting down to -cc1as on x86 too.Benjamin Kramer
The assembler historically didn't make use of any target features, but this has changed when support for old CPUs that don't support long nops was added. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175919 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-22Comment parsing: add CommentOptions to allow specifying custom comment block ↵Dmitri Gribenko
commands Add an ability to specify custom documentation block comment commands via a new class CommentOptions. The intention is that this class will hold future customizations for comment parsing, including defining documentation comments with specific numbers of parameters, etc. CommentOptions instance is a member of LangOptions. CommentOptions is controlled by a new command-line parameter -fcomment-block-commands=Foo,Bar,Baz. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175892 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-22Add -fbracket-depth=N, analogous to -ftemplate-depth= and -fconstexpr-depth=,Richard Smith
to control the check for the C 5.2.4.1 / C++ [implimits] restriction on nesting levels for parentheses, brackets and braces. Some code with heavy macro use exceeds the default limit of 256, but we don't want to increase it generally to avoid stack overflow on stack-constrained systems. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175855 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-19Add support for -fvisibility-ms-compat.John McCall
We treat this as an alternative to -fvisibility=<?> which changes the default value visibility to "hidden" and the default type visibility to "default". Expose a -cc1 option for changing the default type visibility, repurposing -fvisibility as the default value visibility option (also setting type visibility from it in the absence of a specific option). rdar://13079314 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175480 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.

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.

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
