Description

MIPS: Improve registers saving for safepoints in deferred code. This reduces code size of initial snapshot by more than 25Kb. Registers are saved or restored via common stubs, instead of doing it through inlined push/pop instructions (one instruction per register) in generated deferred code. TEST= BUG=
