* Restructure the propagation of -fPIC/-fPIE.Rafael Espindola2016-06-232-6/+6
| | | | | | | | | | | | | The PIC and PIE levels are not independent. In fact, if PIE is defined it is always the same as PIC. This is clear in the driver where ParsePICArgs returns a PIC level and a IsPIE boolean. Unfortunately that is currently lost and we pass two redundant levels down the pipeline. This patch keeps a bool and a PIC level all the way down to codegen. llvm-svn: 273566
* Add support for /Ob1 and -finline-hint-functions flagsHans Wennborg2016-06-221-3/+8
| | | | | | | | | | | | | | | | Add support for /Ob1 (and equivalent -finline-hint-functions), which enable inlining only for functions marked inline, either explicitly (via inline keyword, for example), or implicitly (function definition in class body, for example). This works by enabling inlining pass, and adding noinline attribute to every function not marked inline. Patch by Rudy Pons <rudy.pons@ilod.org>!

| | | | | | | | | | | | | | | | Diagnostics that happen during driver time do not have color output support unless -fcolor-diagonostic is explicitly passed into the driver. This is not a problem for cc1 since dianostic arguments are properly handled and color is enabled by default if the terminal supports it. Make the driver behave like CC1. There are tests that already check for these flags, but for the color itself there's no sensible way to test it.

* [Driver] Add support for -finline-functions and /Ob2 flagsHans Wennborg2016-05-241-2/+6
| | | | | | | | | | | | | | | | | | -finline-functions and /Ob2 are currently ignored by Clang. The only way to enable inlining is to use the global O flags, which also enable other options, or to emit LLVM bitcode using Clang, then running opt by hand with the inline pass. This patch allows to simply use the -finline-functions flag (same as GCC) or /Ob2 in clang-cl mode to enable inlining without other optimizations. This is the first patch of a serie to improve support for the /Ob flags. Patch by Rudy Pons <rudy.pons@ilod.org>! Differential Revision: http://reviews.llvm.org/D20576 llvm-svn: 270609

* [Modules] Use vfs for (recursive) directory iterationBruno Cardoso Lopes2016-05-161-6/+7
| | | | | | | | | | | | | | | | Clang performs directory walk while searching headers inside modules by using the ::sys::fs instead of ::vfs. This prevents any code that uses the VFS (e.g, reproducer scripts) to actually find such headers, since the VFS will never be searched for those. Change these places to use vfs::recursive_directory_iterator and vfs::directory_iterator instead. Differential Revision: http://reviews.llvm.org/D20266 rdar://problem/25880368 llvm-svn: 269661

* [ModuleMap][CrashReproducer] Collect headers from inner frameworksBruno Cardoso Lopes2016-05-131-0/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (1) Collect headers under inner frameworks (frameworks inside other other frameworks). (2) Make sure we also collect the right header files inside them. More info on (2): Consider a dummy framework module B, with header Frameworks/B/B.h. Now consider that another framework A, with header Frameworks/A/A.h, has a layout with a inner framework Frameworks/A/Frameworks/B/B.h, where the "B/B.h" part is a symlink for Frameworks/B/B.h. Also assume that Frameworks/A/A.h includes <B/B.h>. When parsing header Frameworks/A/A.h, framework module lookup is performed in search for B, and it happens that "Frameworks/A/Frameworks/B/B.h" path is registered in the module instead of real "Frameworks/B/B.h". This occurs because "Frameworks/A/Frameworks/B/B.h" is scanned first by the FileManager, when looking for inner framework modules under Frameworks/A/Frameworks. This makes Frameworks/A/Frameworks/B/B.h the default cached named inside the FileManager for the B.h file UID. This leads to modules being built without consistent paths to underlying header files. This is usually not a problem in regular compilation flow, but it's an issue when running the crash reproducer. The issue is that clangs collect "Frameworks/A/Frameworks/B/B.h" but not "Frameworks/B/B.h" into the VFS, leading to err_mmap_umbrella_clash. So make sure we also collect the original header.

* [CrashReproducer] Always use realpath for destinationBruno Cardoso Lopes2016-05-061-20/+13

Add support to expand the `=` as a prefix of the include path with the sysroot if specified. `-isysroot` takes precedence over `--sysroot` as the normal argument behaviour occurs.
