2013-04-12tl;dr: Teach Clang to work around g++ changing its workaround to glibc'sRichard Smith
implementation of C99's attempt to control the C++ standard. *sigh* The C99 standard says that certain macros in <stdint.h>, such as SIZE_MAX, should not be defined when the header is included in C++ mode, unless __STDC_LIMIT_MACROS and __STDC_CONSTANT_MACROS are defined. The C++11 standard says "Thanks, but no thanks" and C11 removed this rule, but various C library implementations (such as glibc) follow C99 anyway. g++ prior to 4.8 worked around the C99 / glibc behavior by defining __STDC_*_MACROS in <cstdint>, which was incorrect, because <stdint.h> is supposed to provide these macros too. g++ 4.8 works around it by defining __STDC_*_MACROS in its builtin <stdint.h> header. This change makes Clang act like g++ 4.8 in this regard: our <stdint.h> now countermands any attempt by the C library to implement the undesired C99 rules, by defining the __STDC_*_MACROS first. Unlike g++, we do this even in C++98 mode, since that was the intent of the C++ committee, matches the behavior required in C11, and matches our built-in implementation of <stdint.h>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179419 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-12Define Neon intrinsics as "static inline" to avoid warning. rdar://13108414Bob Wilson
We had been defining Neon intrinsics as "static" with always_inline attributes. If you use them from an extern inline function, you get a warning, e.g.: static function 'vadd_u8' is used in an inline function with external linkage This change simply adds the inline keyword to avoid that warning. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179406 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-12[analyzer] Print a diagnostic note even if the region cannot be printed.Anna Zaks
There are few cases where we can track the region, but cannot print the note, which makes the testing limited. (Though, I’ve tested this manually by making all regions non-printable.) Even though the applicability is limited now, the enhancement will be more relevant as we start tracking more regions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179396 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-12[analyzer] Show "Returning from ..." note at caller's depth, not callee's.Jordan Rose
Before: 1. Calling 'foo' 2. Doing something interesting 3. Returning from 'foo' 4. Some kind of error here After: 1. Calling 'foo' 2. Doing something interesting 3. Returning from 'foo' 4. Some kind of error here The location of the note is already in the caller, not the callee, so this just brings the "depth" attribute in line with that. This only affects plist diagnostic consumers (i.e. Xcode). It's necessary for Xcode to associate the control flow arrows with the right stack frame. <rdar://problem/13634363> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179351 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-12[analyzer] Don't emit extra context arrow after returning from an inlined call.Jordan Rose
In this code int getZero() { return 0; } void test() { int problem = 1 / getZero(); // expected-warning {{Division by zero}} } we generate these arrows: +-----------------+ | v int problem = 1 / getZero(); ^ | +---+ where the top one represents the control flow up to the first call, and the bottom one represents the flow to the division.* It turns out, however, that we were generating the top arrow twice, as if attempting to "set up context" after we had already returned from the call. This resulted in poor highlighting in Xcode. * Arguably the best location for the division is the '/', but that's a different problem. <rdar://problem/13326040> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179350 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-11Struct-path aware TBAA: uniformize scalar tag and path tag.Manman Ren
For struct-path aware TBAA, we used to use scalar type node as the scalar tag, which has an incompatible format with the struct path tag. We now use the same format: base type, access type and offset. We also uniformize the scalar type node and the struct type node: name, a list of pairs (offset + pointer to MDNode). For scalar type, we have a single pair. These are to make implementaiton of aliasing rules easier. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179335 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-11Force a load when creating a reference to a temporary copied from a bitfield.Jordan Rose
For this source: const int &ref = someStruct.bitfield; We used to generate this AST: DeclStmt [...] `-VarDecl [...] ref 'const int &' `-MaterializeTemporaryExpr [...] 'const int' lvalue `-ImplicitCastExpr [...] 'const int' lvalue <NoOp> `-MemberExpr [...] 'int' lvalue bitfield .bitfield [...] `-DeclRefExpr [...] 'struct X' lvalue ParmVar [...] 'someStruct' 'struct X' Notice the lvalue inside the MaterializeTemporaryExpr, which is very confusing (and caused an assertion to fire in the analyzer - PR15694). We now generate this: DeclStmt [...] `-VarDecl [...] ref 'const int &' `-MaterializeTemporaryExpr [...] 'const int' lvalue `-ImplicitCastExpr [...] 'int' <LValueToRValue> `-MemberExpr [...] 'int' lvalue bitfield .bitfield [...] `-DeclRefExpr [...] 'struct X' lvalue ParmVar [...] 'someStruct' 'struct X' Which makes a lot more sense. This allows us to remove code in both CodeGen and AST that hacked around this special case.
