for awhile, but it's good to make this official.
Just to be clear, Doug and Ted "elected" me to this position.
Might as well add myself to the credits list while I'm at it.

TableGen deps introduced in r136023. This completes the fixing that
dgregor started in r136621. Sorry for missing these the first time
around.
This should fix some of the random race-condition failures people are
still seeing with CMake.

avoid returning early for v8i32 types, which would only be valid for
vector with all zeros. Also split the handling of zeros and ones into separate
checking logic since they are handled differently. This fixes PR10547

them properly. Specifically, the disassembler clearly attempts to
initialiaze all TargetInfo, MCTargeDesc, AsmParser, and Disassembler
sublibraries of registered targets. This makes the CMakeLists accurately
reflect this intent in the code.
This should fix the last of the link errors that I have gotten reports
of on OS X, but if anyone continues to see link errors, continue to
pester me and I'll look into it.

This adds the 'resume' instruction class, IR parsing, and bitcode reading and
writing. The 'resume' instruction resumes propagation of an existing (in-flight)
exception whose unwinding was interrupted with a 'landingpad' instruction (to be
added later).

decide whether condition is likely to be true this way:
x == 0 -> false
x < 0 -> false
x <= 0 -> false
x != 0 -> true
x > 0 -> true
x >= 0 -> true

sub-library for the targets depended on the core target CodeGen library.
This completely undermined the careful work to separate the those
libraries, especially the MC-layer ones. This surfaced as circular
dependencies when the libraries were built as shared libraries where
CMake doesn't allow cycles.
This should fix PR10537. I'll watch the bots to see if there is fallout
on other platforms.

globally scoped constructs. Also, round-trip these dependencies through
the LLVMConfig.cmake.in file thata is used by CMake-based clients of
"installed" (or built) LLVM trees.

This includes registers like EFLAGS and ST0-ST7. We don't check for
liveness issues in the verifier and scavenger because registers will
never be allocated from these classes.
While in SSA form, we do care about the liveness of unallocatable
unreserved registers. Liveness of EFLAGS and ST0 neds to be correct for
MachineDCE and MachineSinking.

This flag is true from isel to register allocation when the machine
function is required to be in SSA form. The TwoAddressInstructionPass
and PHIElimination passes clear the flag.
The SSA flag wil be used by the machine code verifier to check for SSA
form, and eventually an assertion can enforce it in +Asserts builds.
This will catch the common target error of creating machine code with
multiple defs of a virtual register.
