ARM64: Fix and improve MacroAssembler::Printf. · e876dab9

Jacob.Bramley@arm.com authored May 12, 2014

  - W-sized values passed to Printf are now handled correctly by the
    simulator. In AAPCS64, int32_t and int64_t are passed in the same
    way, so this didn't affect non-simulator builds.
  - Since Printf now records the type and size of each argument, it is
    possible to mix argument types.
  - It is now possible to print the stack pointer. There is only one
    remaining restriction: The `csp` register cannot be printed unless
    it is the current stack pointer. This is because it is modified by
    BumpSystemStackPointer when the caller-saved registers are
    preserved.

Reland r20974: Unify and simplify the FastCloneShallowArrayStub · 71789ea1

danno@chromium.org authored May 12, 2014

- Don't bake in length/capacity into full codegen calls of stubs,
allowing boilerplates to increase their capacity without regenerating
code.
- Unify all variants of the clone stub into a single,
length-independent version.
- Various tweaks to make sure that the clone stub doesn't spill and
therefore need an eager stack frame.
- Handle all lengths of array literals in the fast case.
