Jon Kunkee authored
When Assembler::nop is in the header, it is considered an inline function. With GN arg is_component_build=true, the V8_EXPORT_PRIVATE mark on the class causes it to be exported every time the header is included. This, in turn, produces a reference to Register::XRegFromCode. Register::XRegFromCode is only ever defined as an inlined function, so that reference is never fulfilled. Clang can avoid this using the /Fc:dllexportInlines- flag to suppress the export of Assembler::nop and so avoid generating the reference to Register::XRegFromCode. MSVC does not support this flag, so this change suppresses the export by moving Assembler::nop's definition to the .cc file. This also allows it to use the inline definition of Register::XRegFromCode.

Windows ARM64 does cross build for V8 and runs snapshot tool on build host under simulator. Simulator is built with LLP64 data model so 0xFFFFL is 32-bit long by default. It causes problem for the expression "0xFFFFL << shift" when shift is 32, which actually does nothing on x64 because 0xFFFFL is only 32-bit. The issue happens for instruction "movk rd, NUM lsl 32" which is simulated in Simulator::VisitMoveWideImmediate. "0xFFFL << shift" acts as mask to clear bits 32-47 of the orignal value in rd. Under LLP64, the mask happens unexpectedly to the lowest 16 bits of rd register and corrupts the result of rd. Specify 0xFFFFL as 64 bit as 0xFFFFLL fixes this problem.

This change adds two spilling modes: SpillAtDefinition and SpillDeferred. The former is the known spilling mode where we spill at definition. The latter spills only in deferred code regions. This is implemented based on control flow aware allocation and its invariants. The effect is mostly the same as splintering with the exception of forward looking allocation decisions still being impacted by register constraints in deferred code.
