* In the OpenCL mode, the AltiVec mode must be off and checks must be strictTobias Grosser2011-09-211-2/+2
| | | | | | | | | | OpenCL is different from AltiVec in the way it supports vector literals. OpenCL is strict with regards to semantic checks. For example, implicit conversions and explicit casts between vectors of different types are disallowed. Fixes PR10975. Submitted by: Anton Lokhmotov <Anton.lokhmotov@gmail.com> llvm-svn: 140270

| | | | | | | | that this flag must be used only for Microsoft extensions and not emulation; to avoid confusion with the new LangOptions::MicrosoftMode flag. Many of the code now under LangOptions::MicrosoftExt will eventually be moved under the LangOptions::MicrosoftMode flag. llvm-svn: 139987

Microsoft specific tweaking will now fall into 2 categories: - fms-extension: Microsoft specific extensions that should never change the meaning of an otherwise well formed code. Currently map to LangOptions::Microsoft. (To be clearer, I am planning to change the name to LangOptions::MicrosoftExt). - fms-compatibility: Really a MSVC emulation mode. Map to LangOptions::MicrosoftMode. Can change the meaning of an otherwise standard conformant program. llvm-svn: 139978

* [arcmt] Introduce new '-ccc-arcmt-migrate <path>' ARC migration driver option.Argyrios Kyrtzidis2011-07-091-1/+13
| | | | | | | | | | | | | | | | | | | | This is a new mode of migration, where we avoid modifying the original files but we emit temporary files instead. <path> will be used to keep migration process metadata. Currently the temporary files that are produced are put in the system's temp directory but we can put them in the <path> if is necessary. Also introduce new ARC migration functions in libclang whose only purpose, currently, is to accept <path> and provide pairs of original file/transformed file to map from the originals to the files after transformations are applied. Finally introduce the c-arcmt-test utility that exercises the new libclang functions, update arcmt-test, and add tests for the whole process. rdar://9735086. llvm-svn: 134844

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. llvm-svn: 134453

* Make InitHeaderSearch::AddPath and HeaderSearchOptions::AddPath consistentBob Wilson2011-06-211-6/+6
| | | | | | | | use an "IgnoreSysRoot" argument. HeaderSearchOptions had been using the opposite form with "IsSysRootRelative", which made for much confusion when looking at true/false values in calls in AddPath. No functional change. llvm-svn: 133550
* Fix the default libc++ header search path to be sysrooted. Radar 9639692.Bob Wilson2011-06-211-0/+4
| | | | | | | | | 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". llvm-svn: 133547
* IRgen: Add a -fuse-register-sized-bitfield-access option, for testing.Daniel Dunbar2011-06-211-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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 -- llvm-svn: 133532

* Implement Objective-C Related Result Type semantics.Douglas Gregor2011-06-111-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 llvm-svn: 132868

| | | | | | | | | | | | | This is more efficient as it's all done at once at the end of the TU. This could still get expensive, so a flag is provided to disable it. As an added bonus, the diagnostics will now print out a cycle. The PCH test is XFAILed because we currently can't deal with a note emitted in the header and I, being tired, see no other way to verify the serialization of delegating constructors.
