__block variables where the act of initialization/assignment
itself causes the __block variable to be copied to the heap
because the variable is of block type and is being assigned
a block literal which captures the variable.

of the empty key for U. This shouldn't really matter because the tombstone key
for the pair was still distinct from every other key, but it is odd. Patch by

LLVM*AsmPrinter.
GenLibDeps.pl fails to detect vtable references. As this is the only
referenced symbol from LLVM*Desc to LLVM*AsmPrinter on optimized
builds, the algorithm that creates the list of libraries to be linked
into tools doesn't know about the dependency and sometimes places the
libraries on the wrong order, yielding error messages like this:
../../lib/libLLVMARMDesc.a(ARMMCTargetDesc.cpp.o): In function
`llvm::ARMInstPrinter::ARMInstPrinter(llvm::MCAsmInfo const&)':
ARMMCTargetDesc.cpp:(.text._ZN4llvm14ARMInstPrinterC1ERKNS_9MCAsmInfoE
[llvm::ARMInstPrinter::ARMInstPrinter(llvm::MCAsmInfo
const&)]+0x2a): undefined reference to `vtable for
llvm::ARMInstPrinter'

For PCH files, have only one open/close for temporary + rename to be safe from race conditions.
For all other output files open/close the output file directly.

This takes the new 'resume' instruction and turns it into a direct jump to the
caller's landing pad code. The caller's landingpad instruction is merged with
the landingpad instructions of the callee. This is a bit rough and makes some
assumptions in how the code works. But it passes a simple test.

If true and 'model' parameter is not an absolute path, a temp directory will be prepended.
Make it true by default to match current behaviour.

use in KEXTs. However, users/Xcode still need to tweak the linker flags to do
the right thing, and end up using -Xlinker, for example. Instead, have the
driver "do the right thing" when linking when -fapple-kext is present on the
command line, and we should have Xcode use -fapple-kext instead of setting other
flags like -Xlinker -kext or -nodefaultlibs.

This can happen in cases where TableGen generated asm matcher cannot check
whether a register operand is in the right register class. e.g. mem operands.

self.expect("expression -- '(anonymous namespace)::i'", VARIABLES_DISPLAYED_CORRECTLY,

to get rid of the '(anonymous namespace)', which is not c++ syntax, thingy fed to the expression parser.
According to rdar://problem/8668674. It is still marked expectedFailure since the bug has not been fixed.

llvm-mc gives an "invalid operand" error for instructions that take an unsigned
immediate which have the high bit set such as:
pblendw $0xc5, %xmm2, %xmm1
llvm-mc treats all x86 immediates as signed values and range checks them.
A small number of x86 instructions use the imm8 field as a set of bits.
This change only changes those instructions and where the high bit is not
ignored. The others remain unchanged.
