2009-03-12Driver: Add ArgList::hasArg, for testing for the presence of anDaniel Dunbar
argument matching some Option::ID. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66758 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-12Driver: Add Option::getId and Option::matches taking an optionDaniel Dunbar
identifier; we will want to use the latter in situations where we just want to check for a match, but not load options unnecessarily. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66757 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-10Driver: Add host info.Daniel Dunbar
- Replace assorted -ccc-host-* options by -ccc-host-triple which is more sane. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66600 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-10Driver: Handle magic -ccc- options.Daniel Dunbar
- Follows ccc currently, but this functionality should eventually be outside the Driver lib. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66575 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-04Driver: More Option implementation.Daniel Dunbar
- Add Options.def file, collects option information. - Actual option instantiation is handled lazily by OptTable to allow the driver to not need to instantiate all options. - cast<> support for Option, other minor tweaks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66028 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-26Introduce code modification hints into the diagnostics system. When weDouglas Gregor
know how to recover from an error, we can attach a hint to the diagnostic that states how to modify the code, which can be one of: - Insert some new code (a text string) at a particular source location - Remove the code within a given range - Replace the code within a given range with some new code (a text string) Right now, we use these hints to annotate diagnostic information. For example, if one uses the '>>' in a template argument in C++98, as in this code: template<int I> class B { }; B<1000 >> 2> *b1; we'll warn that the behavior will change in C++0x. The fix is to insert parenthese, so we use code insertion annotations to illustrate where the parentheses go: test.cpp:10:10: warning: use of right-shift operator ('>>') in template argument will require parentheses in C++0x B<1000 >> 2> *b1; ^ ( ) Use of these annotations is partially implemented for HTML diagnostics, but it's not (yet) producing valid HTML, which may be related to PR2386, so it has been #if 0'd out. In this future, we could consider hooking this mechanism up to the rewriter to actually try to fix these problems during compilation (or, after a compilation whose only errors have fixes). For now, however, I suggest that we use these code modification hints whenever we can, so that we get better diagnostics now and will have better coverage when we find better ways to use this information. This also fixes PR3410 by placing the complaint about missing tokens just after the previous token (rather than at the location of the next token). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65570 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-19fix a bug introduced in my previous patch: moving clang headers to theChris Lattner
"after" group instead of the system group makes it so #include <limits.h> picks up the *system* limits.h file before clang's. This causes a failure on linux and is definitely not what we want. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65026 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-18stop searching GCC install directories for standard C headers (butChris Lattner
keep searching for C++ headers when in C++ mode). In theory clang should be able to find all of its own headers now. If not, the CPATH or C_INCLUDE_PATH environment variables can be specified to add a include path. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64862 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-17As an experimental hack, emit "instantiated from" information inChris Lattner
diagnostics. I'm not sure I want to keep this, but hey, it's easy and could be useful or something, even if guarded by a -fshow-me-tons-of-details option. A silly example is: #define A B #define C A #define D C int y = D; We now emit: t.c:11:9: error: use of undeclared identifier 'B' int y = D; ^ t.c:9:11: note: instantiated from: #define D C ^ t.c:8:11: note: instantiated from: #define C A ^ t.c:7:11: note: instantiated from: #define A B ^ A more useful example is from tgmath: t.c:4:9: error: no matching function for call to '__tg_acos' return acos(x); ^~~~~~~ /Users/sabre/llvm/Debug/Headers/tgmath-sofar.h:51:17: note: instantiated from: #define acos(x) __tg_acos(x) ^ ... candidate set follows ... This does not yet print ranges in instantiation info, (e.g. highlighting the range "__tg_acos(x)" in the last example), but that could be added if we decide this is a good idea :). Thoughts and bug reports welcome! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64761 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-08Genericize the existing logic for removing duplicate header dirs to applyChris Lattner
the "system dirs win over user dirs" logic to framework and headermap search locations as well as normal directories. This means that clang t.m -F/System/Library/Frameworks will treat /System/Library/Frameworks as a system directory not a user directory. If you use -v, the difference is: Before: ignoring nonexistent directory "/usr/libdata/gcc41" ignoring duplicate framework "/System/Library/Frameworks" #include "..." search starts here: #include <...> search starts here: After: ignoring nonexistent directory "/usr/libdata/gcc41" ignoring duplicate directory "/System/Library/Frameworks" as it is a non-system directory that duplicates a system directory #include "..." search starts here: #include <...> search starts here: This fixes rdar://6566429. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64060 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-30" Attached is a patch for TextDiagnosticPrinter that adds an optionalChris Lattner
parameter that allows users to omit the printing of the source location on a diagnostic. So basically it would omit the "abc.c:5:1: " at the beginning of the line." Patch by Alexei Svitkine! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63396 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-27Introduce a new PresumedLoc class to represent the concept of a locationChris Lattner
as reported to the user and as manipulated by #line. This is what __FILE__, __INCLUDE_LEVEL__, diagnostics and other things should follow (but not dependency generation!). This patch also includes several cleanups along the way: - SourceLocation now has a dump method, and several other places that did similar things now use it. - I cleaned up some code in AnalysisConsumer, but it should probably be simplified further now that NamedDecl is better. - TextDiagnosticPrinter is now simplified and cleaned up a bit. This patch is a prerequisite for #line, but does not actually provide any #line functionality. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63098 91177308-0d34-0410-b5e6-96231b3b80d8
