* Propagate the split dwarf file information through into the backendEric Christopher2013-02-221-3/+4
| | | | | | | | | and through to the debug info in the module. 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. llvm-svn: 175935
* Driver: Pass down the -march setting down to -cc1as on x86 too.Benjamin Kramer2013-02-221-0/+14
| | | | | | | 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. llvm-svn: 175919
* Split out the command handling for split debug info, we're goingEric Christopher2013-02-221-28/+39
| | | | | | | | | to want to propagate some information through the module into the back end and so need to pass it through to codegen. Also make the methods file static so we can use them in other places. llvm-svn: 175916
* Comment parsing: add CommentOptions to allow specifying custom comment block ↵Dmitri Gribenko2013-02-221-0/+3
| | | | | | | | | | | | | | | | 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. llvm-svn: 175892
* Add -fbracket-depth=N, analogous to -ftemplate-depth= and -fconstexpr-depth=,Richard Smith2013-02-221-0/+5
| | | | | | | | | | | 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. llvm-svn: 175855
* Make sure we only use the output file as a base for debug splittingEric Christopher2013-02-221-1/+1
| | | | | | if we're compiling. llvm-svn: 175851
* Make logic smaller.Eric Christopher2013-02-221-7/+4

* [Sanitizer] If -fsanitize-blacklist= option is not explicitly specified, ↵Alexey Samsonov2013-02-191-0/+8
| | | | | | make Clang look for the default sanitizer-specific blacklist in the resource directory. llvm-svn: 175505

| | | | llvm-svn: 175492
* Add support for -fvisibility-ms-compat.John McCall2013-02-191-3/+13
| | | | | | | | | | | | | | | 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 llvm-svn: 175480

* Use -mno-implicit-float by default for kernel/kext code. <rdar://13177960>Bob Wilson2013-02-101-4/+12
| | | | | | | | | | | 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. llvm-svn: 174838
* Recognize -mno-implicit-float option for x86 as well as ARM. <rdar://13180731>Bob Wilson2013-02-101-1/+2
| | | | | | | | | 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. llvm-svn: 174836
* Form the default -fmodules-cache-path= properly.Douglas Gregor2013-02-071-1/+3
| | | | llvm-svn: 174674

| | | | | | consistency. llvm-svn: 174645
* Introduce -fmodules-ignore-macro=NNN to ignore a macro when building/loading ↵Douglas Gregor2013-02-071-0/+3
| | | | | | | | | | | | | | | | | | | | | 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>. llvm-svn: 174560
* Driver and option support for -gsplit-dwarf. This is a part ofEric Christopher2013-02-051-6/+49

* Add -mqpx and -mno-qpx feature flags to toggle use of the PPC QPX vector ↵Hal Finkel2013-02-011-0/+5
| | | | | | | | instruction set I've renamed the altivec test to ppc-features (because now there is more than one feature to test). llvm-svn: 174204
* Add PPC A2Q core and BG/Q preprocessor definitionsHal Finkel2013-02-011-0/+1
| | | | | | The a2q core is the variant of the a2 core used on the BG/Q supercomputers. llvm-svn: 174151
* Enable -fno-altivec, -mno-altivec for PowerPC.Bill Schmidt2013-02-011-0/+6
| | | | | | | | | | | 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. llvm-svn: 174140
* Add support for AArch64 target.Tim Northover2013-01-311-0/+5
| | | | | | | | | | | | | 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. llvm-svn: 174055
* [ubsan] Implement the -fcatch-undefined-behavior flag using a trappingChad Rosier2013-01-291-0/+32
| | | | | | | | | | | 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. llvm-svn: 173848
* Print warning instead of error if optional ASan features are enabled w/o ↵Alexey Samsonov2013-01-281-6/+9

* [driver] Associate a JobAction with each result file. This enables the driverChad Rosier2013-01-241-3/+4
| | | | | | | to delete result files for only those commands that fail. Part of rdar://12984531 llvm-svn: 173361
* [ms-inline asm] Remove the -fenable-experimental-ms-inline-asm flag. MS-styleChad Rosier2013-01-221-4/+0
| | | | | | inline assembly can be enable with -fasm-blocks or -fms-extensions alone. llvm-svn: 173186
* Port r172856: 'Include ubsan runtime even when building a shared library. We ↵Alexey Samsonov2013-01-211-3/+3
| | | | | | don't require executable to be linked with UBSan.' to Mac llvm-svn: 173014

| | | | | | AddressSanitizer use bottom of the address space for the shadow memory. On Linux it can be used with -fPIE/-pie to improve performance. llvm-svn: 172974
* Include ubsan runtime even when building a shared library. We don't require ↵Richard Smith2013-01-181-11/+9
| | | | | | the executable to be linked with UBSan. llvm-svn: 172856
* We want the dwarf AT_producer for assembly source files to match clang'sKevin Enderby2013-01-171-0/+6
| | | | | | | | | | | | | | | | 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 llvm-svn: 172758
* Do not pass -pie flag to linker if -shared specified. This matchesPeter Collingbourne2013-01-171-1/+1
| | | | | | | the gcc driver and makes it possible to add -pie to $CC or similar and have it apply in the right places. llvm-svn: 172753
* Add initial rough support for synthesizing linker options when passedChandler Carruth2013-01-171-1/+10
| | | | | | | | | | | -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. llvm-svn: 172715
* Fix uninitialized bool flag access in SanitizerArgs parserAlexey Samsonov2013-01-161-2/+2
| | | | llvm-svn: 172605
* Add -fmodules-autolink/-fno-modules-autolink (defaults to on) so thatDouglas Gregor2013-01-161-1/+13
| | | | | | users can explicitly enable/disable modules autolinking. llvm-svn: 172592
* Refactor the x86 CPU name logic in the driver and pass -march and -mcpuChandler Carruth2013-01-131-61/+71
| | | | | | | | | | flag information down from the Clang driver into the Gold linker plugin for LTO. This allows specifying -march on the linker commandline and should hopefully have it pass all the way through to the LTO optimizer. Fixes PR14697. llvm-svn: 172354
* [Mips] Pass a combination of +soft-float and -mips16-hard-float flags toSimon Atanasyan2013-01-101-1/+8

* Fix PR14625 by teaching the driver to detect PWD for assembly files.Chandler Carruth2012-12-171-10/+21
| | | | | | | | | | | | | | This also requires adding support to -cc1as for passing the detecting PWD down through LLVM's debug info (which in turn required the LLVM change in r170371). The test case is weak (we only test the driver behavior) because there is currently to infrastructure for running cc1as in the test suite. So those four lines are untested (much like all other lines in that file), but we have a test for the same pattern using llvm-mc in the LLVM repository. llvm-svn: 170373
