2009-05-02Driver: Generate an error when trying to pass an LLVM bc input to aDaniel Dunbar
non-Darwin linker (sorry Gold + LTO-plugin users). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70641 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-02DragonFly ToolChain definition for driver.Daniel Dunbar
- Patch by Alex Hornung! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70635 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-01Implement -fmessage-length=N, which word-wraps diagnostics to N columns. Douglas Gregor
Also, put a line of whitespace between the diagnostic and the source code/caret line when the start of the actual source code text lines up (or nearly lines up) with the most recent line of the diagnostic. For example, here it's okay for the last line of the diagnostic to be (vertically) next to the source line, because there is horizontal whitespace to separate them: decl-expr-ambiguity.cpp:12:16: error: function-style cast to a builtin type can only take one argument typeof(int)(a,5)<<a; However, here is a case where we need the vertical separation (since there is no horizontal separation): message-length.c:10:46: warning: incompatible pointer types initializing 'void (int, float, char, float)', expected 'int (*)(int, float, short, float)' int (*fp1)(int, float, short, float) = f; This is part one of <rdar://problem/6711348>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70578 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-28With -ccc-pch-is-pch, always treat precompiled inputs as PCH,Daniel Dunbar
regardless of extension. - Otherwise we can't expect that just plugging in -ccc-pch-is-pch will work. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70318 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-27Add a header containing the Clang version; make the driver use thisDouglas Gregor
Clang version value rather than hard-coding "1.0". Add PCH and Clang version information into the PCH file. Reject PCH files with the wrong version information. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70264 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-26Driver: Add -std-default= option.Daniel Dunbar
- This can be used to supply a default value for -std=; the idea is that this can be used in conjunction with CCC_ADD_ARGS or QA_OVERRIDE_GCC3_OPTIONS to change the default without having to modify the build system. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70102 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-24Don't run dsymutil when making a fat executable direct source.Daniel Dunbar
- Otherwise, we will end up with stray .dSYM files which don't get lipo'ed or removed. - Ideally we would run dsymutil on the result, but we don't have the infrastructure for that yet. Note that gcc doesn't handle this case either. - <rdar://problem/6809621> [driver] clang leaves .dSYM files lying around in tmp. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69951 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-08Driver: Split out CPP specific options for clang so that we don't endDaniel Dunbar
up adding them twice when running with -no-integrated-cpp or -save-temps. - <rdar://problem/6766636> -save-temps falls over with prefix headers git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68660 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-08More fixes to builtin preprocessor defines.Daniel Dunbar
- Add -static-define option driver can use when __STATIC__ should be defined (instead of __DYNAMIC__). - Don't set __OPTIMIZE_SIZE__ on Os, __OPTIMIZE_SIZE__ is tied to Oz. - Set __NO_INLINE__ following GCC 4.2. - Set __GNU_GNU_INLINE__ or __GNU_STDC_INLINE__ following GCC 4.2. - Set __EXCEPTIONS for Objective-C NonFragile ABI. - Set __STRICT_ANSI__ for standard conforming modes. - I added a clang style test case in utils for this, but its not particularly portable and I don't think it belongs in the test suite. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68621 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-08Make debug info work when using -save-temps.Daniel Dunbar
- This is pretty ugly, but the most obvious solution. Chime in if you have a nicer one. - The problem is that with -save-temps, clang-cc has no idea what the name of the original input file is. However, the user expects to be able to set breakpoints based on the input file name. - We support this by providing a new option -main-file-name (similar to -dumpbase used by gcc) which allows the driver to pass in the original file name. - <rdar://problem/6753383> building with clang using --save-temps gets the compile unit name from the .i file... git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68595 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-08Set __PIC__ (more) correctly.Daniel Dunbar
- Add -pic-level clang-cc option to specify the value for the define, updated driver to pass this. - Added __pic__ - Added OBJC_ZEROCOST_EXCEPTIONS define while I was here (to match gcc). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68584 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-07Driver: Fix forwarding of -{std,ansi,trigraphs} when there areDaniel Dunbar
multiple instances of an option. Also, removed direct -ansi support from clang-cc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68558 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-07Driver: Forward remaining -f options to clang manually.Daniel Dunbar
- Groups are really just intended to hold inherent structure of the options, not be abused for individual tool argument translation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68554 91177308-0d34-0410-b5e6-96231b3b80d8

-isysroot to clang. - Don't forward arbitrary -i* options to clang, just the ones we know about. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68553 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-07Driver: Manually translate a number of -f with no- variants options toDaniel Dunbar
clang. - We will eventually want some more driver infrastructre for this probably. - For now, the clang-cc interface stays relatively the same, but we don't accept multiple instances anymore, or the [no-] variants directly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68550 91177308-0d34-0410-b5e6-96231b3b80d8
