2011-07-01When we create a precompiled preamble, don't copy theDouglas Gregor
CompilerInvocation on the stack, because other objects (e.g., the CompilerInstance) maintain an intrusive reference-counted pointer to the CompilerInvocation. This doesn't matter in the normal case, because we take back the CompilerInvocation. However, during crash recovery, this leads to us trying to free an object on the stack, and hilarity ensues.

2011-06-28Fix PR9279 - Macro expansion stack trace seriously broken with ↵Chris Lattner

This is a one line fix here: + // Don't print recursive instantiation notes from an instantiation note. + Loc = SM.getSpellingLoc(Loc); While here, fix the testcase to be more precise (it got filecheck'ized brutally), and fix EmitCaretDiagnostic to be private and to not pass down the unused 'Level' argument. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133993 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-23avoid using config.h in public headersDylan Noblesmith
This is the only usage in clang's headers, and it's for a define that only exists on CMake builds for the sake of the MSVC compiler, so just use an ifdef instead. Also add an include for config.h in a file that actually needs it, and was picking it up by accident indirectly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133710 91177308-0d34-0410-b5e6-96231b3b80d8

No functional change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133550 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
2011-06-21IRgen: Add a -fuse-register-sized-bitfield-access option, for testing.Daniel Dunbar
- Changes bit-field access policy to try to use (aligned) register sized accesses. The idea here is that by using larger accesses we expose more coalescing potential to the backend when we have situations like adjacent bit-fields in the same structure (which is common), and that the backend should be smart enough to narrow the accesses down when no coalescing is done or when it is shown not to be profitable. -- $ clang -m32 -O3 -S -o - t.c _f0: ## @f0 pushl %ebp movl %esp, %ebp movl 8(%ebp), %eax movb (%eax), %cl andb $-128, %cl orb $1, %cl movb %cl, (%eax) movb 1(%eax), %cl andb $-128, %cl orb $1, %cl movb %cl, 1(%eax) movb 2(%eax), %cl andb $-128, %cl orb $1, %cl movb %cl, 2(%eax) movb 3(%eax), %cl andb $-128, %cl orb $1, %cl movb %cl, 3(%eax) popl %ebp ret $ clang -m32 -O3 -S -o - t.c -Xclang -fuse-register-sized-bitfield-access _f0: ## @f0 pushl %ebp movl %esp, %ebp movl 8(%ebp), %eax movl $-2139062144, %ecx ## imm = 0xFFFFFFFF80808080 andl (%eax), %ecx orl $16843009, %ecx ## imm = 0x1010101 movl %ecx, (%eax) popl %ebp ret -- git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133532 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-16Raise the ARCMT functionality in Clang into proper FrontendActions.Chandler Carruth
These are somewhat special in that they wrap any other FrontendAction, running various ARC transformations or checks prior to the standard action's run. To implement them easily, this extends FrontendAction to have a WrapperFrontendAction utility class which forwards all calls by default to an inner action setup at construction time. This is then subclassed to override the specific behavior needed by the different ARCMT tools. Finally, FrontendTool is taught how to create these wrapper actions from the existing flags and options structures. The result is that clangFrontend no longer depends on clangARCMigrate. This is very important, as clangARCMigrate *heavily* depends on clangFrontend. Fundamentally ARCMigrate is at the same layer as a library like Rewrite, sitting firmly on top of the Frontend, but tied together with the FrontendTool when building the clang binary itself. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133161 91177308-0d34-0410-b5e6-96231b3b80d8

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
