The JIT calls TidyLandingPads to tidy up the landing pads. However, because the
...
JIT doesn't use the MC back-end asm printer to emit labels that it uses, the
section for the MCSymbol is never set. And thus the MCSymbol for the EH label
isn't marked as "defined". Because of that, TidyLandingPads removes the needed
landing pads from the JIT output. This breaks EH for every JIT program.
This is a work-around for this limitation. We pass in the label locations
map. If the label has a non-zero value, then it was "emitted" by the JIT and
TidyLandingPads shouldn't remove that label.
A nicer solution would be to mark the MCSymbol as "used" by the JIT and not rely
upon the section being set to determine if it's defined or not.

Avoid sinking machine instructions into a loop.
...
MachineLoopInfo is already available when MachineSinking runs, so the check is
free.
There is no test case because it would require a critical edge into a loop, and
CodeGenPrepare splits those. This check is just to be extra careful.

Implement rdar://7860110 (also in target/readme.txt) narrowing

a load/or/and/store sequence into a narrower store when it is
safe. Daniel tells me that clang will start producing this sort
of thing with bitfields, and this does trigger a few dozen times
on 176.gcc produced by llvm-gcc even now.
This compiles code like CodeGen/X86/2009-05-28-DAGCombineCrash.ll
into:
movl %eax, 36(%rdi)
instead of:
movl $4294967295, %eax ## imm = 0xFFFFFFFF
andq 32(%rdi), %rax
shlq $32, %rcx
addq %rax, %rcx
movq %rcx, 32(%rdi)
and each of the testcases into a single store. Each of them used
to compile into craziness like this:
_test4:
movl $65535, %eax ## imm = 0xFFFF
andl (%rdi), %eax
shll $16, %esi
addl %eax, %esi
movl %esi, (%rdi)

Fixed another assert exposed by fuzzing. The utility function getRegisterEnum()
...
was asserting because the (RegClass, RegNum) combination doesn't make sense from
an encoding point of view.
Since getRegisterEnum() is used all over the place, to change the code to check
for encoding error after each call would not only bloat the code, but also make
it less readable. An Err flag is added to the ARMBasicMCBuilder where a client
can set a non-zero value to indicate some kind of error condition while building
up the MCInst. ARMBasicMCBuilder::BuildIt() checks this flag and returns false
if a non-zero value is detected.
