2013-03-27UBSan: Don't diagnose inf/nan conversions between floating-point types. It's ↵Richard Smith
far from clear whether these have undefined behavior, and these checks are helping no-one. Keep the double->float overflow warnings, though, since those are useful in practice, even though it's unclear whether such operations have defined behavior. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178194 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-26Fix uninitialized read of CalleeWithThisReturn.Evgeniy Stepanov
CalleeWithThisReturn can be left initialized if HasThisReturn() is false.

2013-03-23Under ARC, when we're passing the address of a strong variableJohn McCall
to an out-parameter using the indirect-writeback conversion, and we copied the current value of the variable to the temporary, make sure that we register an intrinsic use of that value with the optimizer so that the value won't get released until we have a chance to retain it. rdar://13195034 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177813 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-22[ms-cxxabi] Implement member data pointers for non-dynamic classesReid Kleckner
Summary: For non-dynamic classes (no virtual bases), member data pointers are simple offsets from the base of the record. Dynamic classes use an aggregate for member data pointers and are therefore currently unsupported. Unlike Itanium, the ms ABI uses 0 to represent null for polymorphic classes. Non-polymorphic classes use -1 like Itanium, since 0 is a valid field offset.

2013-03-20Exploit this-return of a callsite in a this-return function.Manman Ren
For constructors/desctructors that return 'this', if there exists a callsite that returns 'this' and is immediately before the return instruction, make sure we are using the return value from the callsite. We don't need to keep 'this' alive through the callsite. It also enables optimizations in the backend, such as tail call optimization. Updated from r177211. rdar://12818789 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177541 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-20The flag "-coverage-function-names-in-data" is actually backwards -- we doNick Lewycky
emit function names in .gcda files by default, and the flag turns that off! Rename the flag to make it match what it actually does. This keeps the default format compatible with gcc 4.2. Also add a test for this flag. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177475 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-19PR15383: When -fsanitize=float-cast-overflow checks a float-to-int conversion,Richard Smith
it wasn't taking into account that the float should be truncated *before* the range check happens. Thus (unsigned)-0.99 and (unsigned char)255.9 have defined behavior and should not be trapped. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177362 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-18This code works around what appears to be a bug in another part of clang.Reed Kotler
I have filed http://llvm.org/bugs/show_bug.cgi?id=15538 against clang. This code is safer anyway because "cast" assumes you really know that it's okay to make the cast. In this case isa should not be false and dyn_cast should not return null as far as I understand. But everything else is valid so I did not want to revert my previous patch for attributes mips16/nomips16 or use an llvm_unreachable here which would make a number of our tests fail for mips. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177329 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-15Force column info only for direct inlined functions. This should strikeAdrian Prantl
the balance between expected behavior and compatibility with the gdb testsuite. (GDB gets confused if we break an expression into multiple debug stmts so we enable this behavior only for inlined functions.

2013-03-13Have these attriubtes set to 'true' or 'false'.Bill Wendling
The back-end cannot differentiate between functions that are from a .ll file and those generated from the front-end. We cannot then take the non-precense of these attributes as a "false" value.
