Add a "seen blocks" cache to LVI to avoid a linear scan over the whole cache just to remove no blocks from the maps.

-15% on ARMDisassembler.cpp (Release build).  It's not that great to add another
layer of caching to the caching-heavy LVI but I don't see a better way.

libgcc sets the stack limit field in TCB to 256 bytes above the actual
allocated stack limit.  This means if the function's stack frame needs
less than 256 bytes, we can just compare the stack pointer with the
stack limit.  This should result in lesser calls to __morestack.

llvm-svn: 145766

Currently LLVM pads the call to __morestack with a add and sub of 8
bytes to esp.  This isn't correct since __morestack expects the call
to be followed directly by a ret.

This commit also adjusts the relevant test-case.

matter since the old JIT is going away. Add tsan annotations to ignore the
race.

Fixed deadstoreelimination bug where negative indices were incorrectly causing the optimisation to occur

Turns out long long + unsigned long long is unsigned.  Doh!

change, now you need a TargetOptions object to create a TargetMachine. Clang
patch to follow.

One small functionality change in PTX. PTX had commented out the machine
verifier parts in their copy of printAndVerify. That now calls the version in
LLVMTargetMachine. Users of PTX who need verification disabled should rely on
not passing the command-line flag to enable it.

passed via the stack (i.e., undefined high-order bits).

Add the 16-bit lane variants while I'm at it.

llvm-svn: 145693

Fix quadratic behavior in InlineFunction by fetching the personality function of the callee once and not for every invoke in the caller.

The callee is usually smaller than the caller, too. This reduces the compile
time of ARMDisassembler.cpp by 32% (Release build). It still takes ages to
compile though.

The alias pseudos need cleaned up for size suffix handling, but this gets
the basics working. Will be cleaning up and adding more.

Also fix an accidental implicit cast from the OptLevel enum

didn't.
