2013-01-18Reduce penalty for splitting between ")" and ".".Daniel Jasper
').' is likely part of a builder pattern statement. This is based upon a patch developed by Nico Weber. Thank you! Before: int foo() { return llvm::StringSwitch<Reference::Kind>(name).StartsWith( ".eh_frame_hdr", ORDER_EH_FRAMEHDR).StartsWith( ".eh_frame", ORDER_EH_FRAME).StartsWith(".init", ORDER_INIT).StartsWith( ".fini", ORDER_FINI).StartsWith(".hash", ORDER_HASH).Default(ORDER_TEXT); } After: int foo() { return llvm::StringSwitch<Reference::Kind>(name) .StartsWith(".eh_frame_hdr", ORDER_EH_FRAMEHDR) .StartsWith(".eh_frame", ORDER_EH_FRAME) .StartsWith(".init", ORDER_INIT).StartsWith(".fini", ORDER_FINI) .StartsWith(".hash", ORDER_HASH).Default(ORDER_TEXT); } Probably not ideal, but makes many cases much more readable. The changes to overriding-ftemplate-comments.cpp don't seem better or worse. We should address those soon. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172804 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-17-Wunsequenced: if the LHS of an &&, || or ?: is not constant, check forRichard Smith
unsequenced operations in the RHS. We don't compare the RHS with the rest of the expression yet; such checks will need care to avoid diagnosing unsequenced operations which are both in conditionally-evaluated subexpressions which actually can't occur together, such as in '(b && ++x) + (!b && ++x)'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172760 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-17We want the dwarf AT_producer for assembly source files to match clang'sKevin Enderby
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 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172758 91177308-0d34-0410-b5e6-96231b3b80d8

-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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172715 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-17Suppress all -Wunused-value warnings from macro body expansions.Matt Beaumont-Gay
This is inspired by a number of false positives in real code, including PR14968. I've added test cases reduced from these false positives to test/Sema/unused-expr.c, as well as corresponding test cases that pass the offending expressions as arguments to a no-op macro to ensure that we do warn there. This also removes my previous tweak from r166522/r166534, so that we warn on unused cast expressions in macro arguments. There were several test cases that were using -Wunused-value to test general diagnostic emission features; I changed those to use other warnings or warn on a macro argument expression. I stared at the test case for PR14399 for a while with Richard Smith and we believe the new test case exercises the same codepaths as before. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172696 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-16Rework the traversal of Objective-C categories and extensions toDouglas Gregor
consider (sub)module visibility. The bulk of this change replaces myriad hand-rolled loops over the linked list of Objective-C categories/extensions attached to an interface declaration with loops using one of the four new category iterator kinds: visible_categories_iterator: Iterates over all visible categories and extensions, hiding any that have their "hidden" bit set. This is by far the most commonly used iterator. known_categories_iterator: Iterates over all categories and extensions, ignoring the "hidden" bit. This tends to be used for redeclaration-like traversals. visible_extensions_iterator: Iterates over all visible extensions, hiding any that have their "hidden" bit set. known_extensions_iterator: Iterates over all extensions, whether they are visible to normal name lookup or not. The effect of this change is that any uses of the visible_ iterators will respect module-import visibility. See the new tests for examples. Note that the old accessors for categories and extensions are gone; there are *Raw() forms for some of them, for those (few) areas of the compiler that have to manipulate the linked list of categories directly. This is generally discouraged. Part two of <rdar://problem/10634711>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172665 91177308-0d34-0410-b5e6-96231b3b80d8
