2011-07-06Call objc_terminate() instead of abort() when a cleanup throws anJohn McCall
exception in Objective-C; in Objective-C++ we still use std::terminate(). This is only available in very recent runtimes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134456 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-06Change the driver's logic about Objective-C runtimes: abstract out aJohn McCall
structure to hold inferred information, then propagate each invididual bit down to -cc1. Separate the bits of "supports weak" and "has a native ARC runtime"; make the latter a CodeGenOption. The tool chain is still driving this decision, because it's the place that has the required deployment target information on Darwin, but at least it's better-factored now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134453 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-02Make clang behave in a gcc-compatible way in the presence of multiple flags ↵Eli Friedman
for the same x86 target feature (e.g. -mno-sse -msse). gcc uses a somewhat unintuitive algorithm here in that the enabled SSE instructions is based on the order of the *last* flag for *each* feature-level, so that "-mno-sse -msse2" only enables SSE2, but "-mno-sse -msse2 -msse" enables all SSE levels. Issue reported on cfe-dev. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134296 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-21Fix the default libc++ header search path to be sysrooted. Radar 9639692.Bob Wilson
The -cxx-isystem path is not prefixed with the sysroot directory, so it's not a good way for the driver to set the system default C++ search path. Instead, add -stdlib as a cc1 option and teach the frontend how to find the headers. The driver can then just pass -stdlib through to "cc1". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133547 91177308-0d34-0410-b5e6-96231b3b80d8

that the linker has a place to put the temporary object file and can leave it around (for the driver to clean up).

2011-06-11Implement Objective-C Related Result Type semantics.Douglas Gregor
Related result types apply Cocoa conventions to the type of message sends and property accesses to Objective-C methods that are known to always return objects whose type is the same as the type of the receiving class (or a subclass thereof), such as +alloc and -init. This tightens up static type safety for Objective-C, so that we now diagnose mistakes like this: t.m:4:10: warning: incompatible pointer types initializing 'NSSet *' with an expression of type 'NSArray *' [-Wincompatible-pointer-types] NSSet *array = [[NSArray alloc] init]; ^ ~~~~~~~~~~~~~~~~~~~~~~ /System/Library/Frameworks/Foundation.framework/Headers/NSObject.h:72:1: note: instance method 'init' is assumed to return an instance of its receiver type ('NSArray *') - (id)init; ^ It also means that we get decent type inference when writing code in Objective-C++0x: auto array = [[NSMutableArray alloc] initWithObjects:@"one", @"two",nil]; // ^ now infers NSMutableArray* rather than id git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@132868 91177308-0d34-0410-b5e6-96231b3b80d8

Preserve the original triple in the NetBSD toolchain when using -m32 or -m64 and the resulting effective target is different from the triple it started with. This allows -m32 to use the same assembler/linking in cross-compiling mode and avoids confusion about passing down target specific flags in that case like --32. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@131404 91177308-0d34-0410-b5e6-96231b3b80d8
