Rafael Espindola 16431fe7a7 Add FILE_SHARE_WRITE to openFileForRead.
This should fix the windows bots. It looks like the failing tests are of the
form

prog1 > file
prog2 file

and prog2 fails trying to read the file. The best fix would probably be to close
stdout/stderr in prog1, but it was not the intention of 186511 to change this,
so just restore the old behavior for now.

Jordan Rose 5f6c173e7c [analyzer] Handle C++11 member initializer expressions.
Previously, we would simply abort the path when we saw a default member
initialization; now, we actually attempt to evaluate it. Like default
arguments, the contents of these expressions are not actually part of the
current function, so we fall back to constant evaluation.

Jordan Rose 5fded08403 [analyzer] Handle C string default values for const char * arguments.
Previously, SValBuilder knew how to evaluate StringLiterals, but couldn't
handle an array-to-pointer decay for constant values. Additionally,
RegionStore was being too strict about loading from an array, refusing to
return a 'char' value from a 'const char' array. Both of these have been
fixed.

Jordan Rose 05b2f98d89 [analyzer] Treat std::initializer_list as opaque rather than aborting.
Previously, the use of a std::initializer_list (actually, a
CXXStdInitializerListExpr) would cause the analyzer to give up on the rest
of the path. Now, it just uses an opaque symbolic value for the
initializer_list and continues on.

At some point in the future we can add proper support for initializer_list,
with access to the elements in the InitListExpr.

* Simplifies the unix version a bit.

Duncan Sands 80f122fefb Tweak the cmake interaction between CMAKE_BUILD_TYPE and LLVM_ENABLE_ASSERTIONS.
The issue is that CMAKE_BUILD_TYPE=RelWithDebInfo LLVM_ENABLE_ASSERTIONS=ON was
not building with assertions enabled.  (I was unable to find what in the LLVM
source tree was adding -DNDEBUG to the build line in this case, so decided that
it must be cmake itself that was adding it - this may depend on the cmake
version).  The fix treats any mode that is not Debug as being the same as
Release for this purpose (previously it was being assumed that cmake would only
add -DNDEBUG for Release and not for RelWithDebInfo or MinSizeRel).  If other
versions of cmake don't add -DNDEBUG for RelWithDebInfo then that's OK: with
this change you just get a useless but harmless -UNDEBUG or -DNDEBUG.

Pavel Labath 9ced602cc6 [analyzer] Add very limited support for temporary destructors
Summary:
This patch enables ExprEndgine to reason about temporary object destructors.
However, these destructor calls are never inlined, since this feature is still
broken. Still, this is sufficient to properly handle noreturn temporary
destructors and close bug #15599. I have also enabled the cfg-temporary-dtors
analyzer option by default.

JF Bastien 27dcbb24e5 Propagate alignment for _Complex
_Complex load/store didn't have their alignment set properly, which was visible when GCC's torture tests use volatile _Complex.

Update some existing tests to check for alignment, and add a new test which also has over-aligned volatile _Complex (since the imaginary part shouldn't be overaligned, only the real part).

JF Bastien cd4c64d234 Fix ARMFastISel::ARMEmitIntExt shift emission
My patch 'r183551 - ARM FastISel integer sext/zext improvements' was incorrect when emitting ARM register-immediate ASR, LSL, LSR instructions: they are pseudo-instructions in ARMInstrInfo.td and I should have used MOVsi instead.

This is not an issue when code is generated through a .s file, but is an issue when generated straight to a .o (-filetype=obj).

Hal Finkel 40f76d5830 PPC: Add CTR-register clobber to builtin setjmp
Because the builtin longjmp implementation uses a CTR-based indirect jump, when
the control flow arrives at the builtin setjmp call, the CTR register has
necessarily been clobbered. Correspondingly, this adds CTR to the list of
implicit definitions of the builtin setjmp pseudo instruction.

We don't need to add CTR to the implicit definitions of builtin longjmp
because, even though it does clobber the CTR register, the control flow cannot
return to inside the loop unless there is also a builtin setjmp call.

Rafael Espindola b6fea4c618 Don't fallback to copy + delete in rename.
Rename's documentation says "Files are renamed as if by POSIX rename()". and it
is used for atomically updating output files from a temporary. Having rename
fallback to a non atomic copy has the potential to hide bugs, like using
a temporary file in /tmp instead of a unique name next to the final destination.
