Similar to my previous -exports-trie option, the -rebase option dumps info from
the LC_DYLD_INFO load command. The rebasing info is a list of the the locations
that dyld needs to adjust if a mach-o image is not loaded at its preferred
address. Since ASLR is now the default, images almost never load at their
preferred address, and thus need to be rebased by dyld.

The raw profiles that are generated in compiler-rt always add padding
so that each profile is aligned, so we can simply treat files that
don't have this property as malformed.
Caught by Alexey's new ubsan bot. Thanks!

enabled. A good chunk of the MIsNeedChainEdge() is logic that is valid and should be applied even for targets
that are not using for alias analysis.

Apparently, PEEKUSER/POKEUSER is something x86 specific, so I had to rework it for AArch64. This fixes assertion that occurs whenever lldb started on AArch64 device tried to read PC register (or any other register)
See http://reviews.llvm.org/D5232 for more details.
Change by Paul Osmialowski.

Vector MUL/MLAs have tied operands, which gives us extra constraints
that we currently can't handle. Instead of silently doing the wrong
thing, remove support to be readded later properly.
llvm-svn: 217690
Defs are seen before uses, so a def without the kill flag doesn't necessarily
mean that the register is not killed on that instruction. It may be killed
in a later use operand.

As far as I can tell UTF-8 has been supported since the beginning of Python's
codec support, and it's the de facto standard for text these days, at least
for primarily-English text. This allows us to put Unicode into lit RUN lines.

Cross-class copies being expensive is actually a trait of the microarchitecture, but as I haven't yet seen an example of a microarchitecture where they're cheap it seems best to just enable this by default, covering the non-mcpu build case.

It turned out that we have to bridge more stuff between the executable
and the ASan RTL DLL than just __asan_option_detect_stack_use_after_return.
See PR20918 for more details.

We now verify that such functions are correctly detected even in combination
with delinearization. This change is added to ensure we have good test coverage
for the subsequent delinearization fix.
We also remove unnecessary instructions from the test case.

Summary:
Each check can implement readOptions and storeOptions methods to read
and store custom options. Each check's options are stored in a local namespace
to avoid name collisions and provide some sort of context to the user.
