* [CodeGen] Fix assignments of inline layouts into the byref structureVedant Kumar2015-12-212-1/+5
| | | | | | | | | | | | | | When using blocks, a byref structure is created to represent the closure. The "byref.layout" field of this structure is an i8*. However, some 'inline' layouts are represented as i64's, not i8*'s. Prior to r246985 we cast the i64 'inline' layout to an i8* before assigning it into the byref structure. This patch brings the cast back and adds a regression test. rdar://23713871 llvm-svn: 256185

* clang-format: Extend detection of the "main" #include to use the filenameDaniel Jasper2015-12-211-18/+16
| | | | | | | | | | | Before, the first (non-system) header in a file was considered to be the main include. This is conservative as it makes clang-format change the #include order less often. Instead implement some basic usage of the filename itself. With this patch, clang-format considers every header to be a main include if the header file's basename is a prefix to the filename the #include is in. llvm-svn: 256148

* Driver part of debugger tuning.Paul Robinson2015-12-192-24/+74
| | | | | | | | | | | | | | | | Adds driver options named -glldb and -gsce to mean -g plus tuning for lldb and SCE debuggers respectively; the existing -ggdb option does the same for gdb. Existing options -ggdb0, -ggdb1 etc. unpack into -ggdb -g<N>. (There will not be -glldb<N> or -gsce<N> options.) The tuning gets a target-specific default in the driver, and is passed into cc1 with the new -debugger-tuning option. As fallout, fixes where '-gsplit-dwarf -g0' would ignore the -g0 part on Linux.

* Split RequireCompleteType into a function that actually requires that the typeRichard Smith2015-12-1815-114/+96
| | | | | | | | | | | | | | | | | | | is complete (with an error produced if not) and a function that merely queries whether the type is complete. Either way we'll trigger instantiation if necessary, but only the former will diagnose and recover from missing module imports. The intent of this change is to prevent a class of bugs where code would call RequireCompleteType(..., 0) and then ignore the result. With modules, we must check the return value and use it to determine whether the definition of the type is visible. This also fixes a debug info quality issue: calls to isCompleteType do not trigger the emission of debug information for a type in limited-debug-info mode. This allows us to avoid emitting debug information for type definitions in more cases where we believe it is safe to do so. llvm-svn: 256049

* PIC should not be enabled by default on Darwin with -static.Bob Wilson2015-12-181-0/+3
| | | | | | | | | | | r245667 changed -static so that it doesn't override an explicit -fPIC option, but -static should still change the default for Darwin for -fno-PIC. This matches longstanding GCC and Clang behavior on Darwin and changing it would be disruptive, with no significant benefit. http://reviews.llvm.org/D15455 rdar://problem/23811045 llvm-svn: 256026

* [CUDA] Make vtable construction aware of host/device side of CUDA compilation.Artem Belevich2015-12-172-0/+33
| | | | | | | | | | | | | | | | | | | C++ emits vtables for classes that have key function present in the current TU. While we compile CUDA the fact that key function was found in this TU does not mean that we are going to generate code for it. E.g. vtable for a class with host-only methods should not (and can not) be generated on device side, because we'll never generate code for them during device-side compilation. This patch adds an extra CUDA-specific check during key method computation and filters out potential key methods that are not suitable for this side of CUDA compilation. When we codegen vtable, entries for unsuitable methods are set to null. Differential Revision: http://reviews.llvm.org/D15309 llvm-svn: 255911

* [analyzer] Better detect when C++ object was constructed into existing region.Devin Coughlin2015-12-173-38/+101
| | | | | | | | | | | | | | | | | | | | | | | | | When the analyzer evaluates a CXXConstructExpr, it looks ahead in the CFG for the current block to detect what region the object should be constructed into. If the constructor was directly constructed into a local variable or field region then there is no need to explicitly bind the constructed value to the local or field when analyzing the DeclStmt or CXXCtorInitializer that called the constructor. Unfortunately, there were situations in which the CXXConstructExpr was constructed into a temporary region but when evaluating the corresponding DeclStmt or CXXCtorInitializer the analyzer assumed the object was constructed into the local or field. This led to spurious warnings about uninitialized values (PR25777). To avoid these false positives, this commit factors out the logic for determining when a CXXConstructExpr will be directly constructed into existing storage, adds the inverse logic to detect when the corresponding later bind can be safely skipped, and adds assertions to make sure these two checks are in sync. rdar://problem/21947725 llvm-svn: 255859
