Complete Rewrite of CGRecordLayoutBuilder CGRecordLayoutBuilder was aging, complex, multi-pass, and shows signs of existing before ASTRecordLayoutBuilder. It redundantly performed many layout operations that are now performed by ASTRecordLayoutBuilder and asserted that the results were the same. With the addition of support for the MS-ABI, such as placement of vbptrs, vtordisps, different bitfield layout and a variety of other features, CGRecordLayoutBuilder was growing unwieldy in its redundancy. This patch re-architects CGRecordLayoutBuilder to not perform any redundant layout but rather, as directly as possible, lower an ASTRecordLayout to an llvm::type. The new architecture is significantly smaller and simpler than the CGRecordLayoutBuilder and contains fewer ABI-specific code paths. It's also one pass. The architecture of the new system is described in the comments. For the most part, the new system simply takes all of the fields and bases from an ASTRecordLayout, sorts them, inserts padding and dumps a record. Bitfields, unions and primary virtual bases make this process a bit more complicated. See the inline comments. In addition, this patch updates a few lit tests due to the fact that the new system computes more accurate llvm types than CGRecordLayoutBuilder. Each change is commented individually in the review.

// CHECK: store i32 {{.*}}, i32* [[I]]
When forming a function call or message send expression, be sure to strip cv-qualifiers from the expression's type when the language calls for it: in C, that's all the time, while C++ only does it for non-class types. Centralized the computation of the call expression type in QualType::getCallResultType() and some helper functions in other nodes (FunctionDecl, ObjCMethodDecl, FunctionType), and updated all relevant callers of getResultType() to getCallResultType(). Fixes PR7598 and PR7463, along with a bunch of getResultType() call sites that weren't stripping references off the result type (nothing stripped cv-qualifiers properly before this change). llvm-svn: 108234

// CHECK: load i32, i32* [[I]]
Improve filechecking of volatile test. My previous attempt was extremely deficient, allowing more volatiles to be introduced and not even checking all of the ones that are present.

Complete Rewrite of CGRecordLayoutBuilder CGRecordLayoutBuilder was aging, complex, multi-pass, and shows signs of existing before ASTRecordLayoutBuilder. It redundantly performed many layout operations that are now performed by ASTRecordLayoutBuilder and asserted that the results were the same. With the addition of support for the MS-ABI, such as placement of vbptrs, vtordisps, different bitfield layout and a variety of other features, CGRecordLayoutBuilder was growing unwieldy in its redundancy. This patch re-architects CGRecordLayoutBuilder to not perform any redundant layout but rather, as directly as possible, lower an ASTRecordLayout to an llvm::type. The new architecture is significantly smaller and simpler than the CGRecordLayoutBuilder and contains fewer ABI-specific code paths. It's also one pass. The architecture of the new system is described in the comments. For the most part, the new system simply takes all of the fields and bases from an ASTRecordLayout, sorts them, inserts padding and dumps a record. Bitfields, unions and primary virtual bases make this process a bit more complicated. See the inline comments. In addition, this patch updates a few lit tests due to the fact that the new system computes more accurate llvm types than CGRecordLayoutBuilder. Each change is commented individually in the review.

Change memcpy/memove/memset to have dest and source alignment attributes (Step 1). Summary: Upstream LLVM is changing the the prototypes of the @llvm.memcpy/memmove/memset intrinsics. This change updates the Clang tests for this change. The @llvm.memcpy/memmove/memset intrinsics currently have an explicit argument which is required to be a constant integer. It represents the alignment of the dest (and source), and so must be the minimum of the actual alignment of the two. This change removes the alignment argument in favour of placing the alignment attribute on the source and destination pointers of the memory intrinsic call. For example, code which used to read: call void @llvm.memcpy.p0i8.p0i8.i32(i8* %dest, i8* %src, i32 100, i32 4, i1 false) will now read call void @llvm.memcpy.p0i8.p0i8.i32(i8* align 4 %dest, i8* align 4 %src, i32 100, i1 false) At this time the source and destination alignments must be the same (Step 1). Step 2 of the change, to be landed shortly, will relax that contraint and allow the source and destination to have different alignments. llvm-svn: 322964

Improve filechecking of volatile test. My previous attempt was extremely deficient, allowing more volatiles to be introduced and not even checking all of the ones that are present. This attempt doesn't try to keep track of the values stored or offsets within particular objects, just that the correct objects are accessed in a correctly volatile manner throughout. llvm-svn: 174700

Revert r112043, static volatiles are removed by the optimizer. Thanks Chris! llvm-svn: 112112

Change memcpy/memove/memset to have dest and source alignment attributes (Step 1). Summary: Upstream LLVM is changing the the prototypes of the @llvm.memcpy/memmove/memset intrinsics. This change updates the Clang tests for this change. The @llvm.memcpy/memmove/memset intrinsics currently have an explicit argument which is required to be a constant integer. It represents the alignment of the dest (and source), and so must be the minimum of the actual alignment of the two. This change removes the alignment argument in favour of placing the alignment attribute on the source and destination pointers of the memory intrinsic call. For example, code which used to read: call void @llvm.memcpy.p0i8.p0i8.i32(i8* %dest, i8* %src, i32 100, i32 4, i1 false) will now read call void @llvm.memcpy.p0i8.p0i8.i32(i8* align 4 %dest, i8* align 4 %src, i32 100, i1 false) At this time the source and destination alignments must be the same (Step 1). Step 2 of the change, to be landed shortly, will relax that contraint and allow the source and destination to have different alignments. llvm-svn: 322964

Basic support for volatile loads and stores. Stores the volatile qualifier in the lvalue, and changes lvalue loads/stores to honor the volatile flag. Places which need some further attention are marked with FIXMEs. Patch by Cédric Venet. llvm-svn: 52264
