9 years ago[turbofan] Right hand side of shifts needs ToUint32.
bmeurer [Fri, 3 Jul 2015 11:41:54 +0000 (04:41 -0700)]
[turbofan] Right hand side of shifts needs ToUint32.

Currently we lower shifts directly to machine operators, and add an
appropriate Word32And to implement the & 0x1F operation on the right
hand side required by the specification. However for Word32And we assume
Int32 in simplified lowering, which is basically changes the right hand
side bit interpretation for the shifts from Uint32 to Int32, which is
obviously wrong. So now we represent that explicitly by proper
simplified operators for the shifts, which are lowered to machine in
simplified lowering.

PPC: Make context register implicit for CallInterfaceDescriptors

Original commit message:
    Up until now the context register was listed explicitly in each stub's
    CallInterfaceDescriptor. This was problematic, because it was listed
    first in the list of register parameters--which is fine for Crankshaft,

    the end of all function parameters. Now the context register is no
    longer in the register list and can be handled appropriately by both
