2011-10-03Allow getting all source locations of selector identifiers in a ObjCMessageExpr.Argyrios Kyrtzidis
Instead of always storing all source locations for the selector identifiers we check whether all the identifiers are in a "standard" position; "standard" position is -Immediately before the arguments: [foo first:1 second:2] -With a space between the arguments: [foo first: 1 second: 2] -For nullary selectors, immediately before ']': [foo release] In such cases we infer the locations instead of storing them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140987 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-03Rework the selection of builtin library search paths on Linux toChandler Carruth
precisely match the pattern and logic used by the GCC driver on Linux as of a recent SVN checkout. This happens to follow a *much* more principled approach. There is a strict hierarchy of paths examined, first with multilib-suffixing, second without such suffixing. Any and all of these directories which exist will be added to the library search path when using GCC. There were many places where Clang followed different paths, omitted critical entries, and worst of all (in terms of challenges to debugging) got the entries in a subtly wrong order. If this breaks Clang on a distro you use, please let me know, and I'll work with you to figure out what is needed to work on that distro. I've checked the behavior of the latest release of Ubuntu, OpenSUSE, Fedora, and Gentoo. I'll be testing it on those as well as Debian stable and unstable and ArchLinux. I may even dig out a Slackware install. No real regression tests yet, those will follow once I add enough support for sysroot to simulate various distro layouts in the testsuite. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140981 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-02Sorry, I misunderstood the interaction here; the GNU runtime doesJohn McCall
support both a fragile and non-fragile ABI, and it can be selected at runtime.

2011-10-02Make -fobjc-nonfragile-abi the -cc1 default, since it's theJohn McCall
increasingly prevailing case to the point that new features like ARC don't even support the fragile ABI anymore. This required a little bit of reshuffling with exceptions because a check was assuming that ObjCNonFragileABI was only being set in ObjC mode, and that's actually a bit obnoxious to do. Most, though, it involved a perl script to translate a ton of test cases. Mostly no functionality change for driver users, although there are corner cases with disabling language-specific exceptions that we should handle more correctly now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140957 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-01constexpr: semantic checking for constexpr functions and constructors. Based inRichard Smith
part on patches by Peter Collingbourne. We diverge from the C++11 standard in a few areas, mostly related to checking constexpr function declarations, and not just definitions. See WG21 paper N3308=11-0078 for details. Function invocation substitution is not available in this patch; constexpr functions cannot yet be used from within constant expressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140926 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-01Revert r140604: "Let -B work for ld paths on Linux."Chandler Carruth
This patch may do what it describes, it may not. It's hard to tell as its completely unclear what this is supposed to do. There are also no test cases. More importantly, this seems to have broken lots of linker invocations on multilib Linux systems. The manual pages for 'ld' on Linux mention translating a '=' at the beginning of the path into a *configure time* sysroot prefix (this is, I believe, distinct from the --sysroot flag which 'ld' also can support). I tested this with a normal binutils 'ld', a binutils 'ld' with the sysroot flag enabled, and gold with the sysroot flag enabled, and all of them try to open the path '=/lib/../lib32', No translation occurs. I think at the very least inserting an '=' needs to be conditioned on some indication that it is supported and desired. I'm also curious to see what toolchain and whan environment cause it to actually make a difference. I'm going to add a test case for basic sanity of Linux 'ld' invocations from Clang in a follow-up commit that would have caught this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140908 91177308-0d34-0410-b5e6-96231b3b80d8
