cmd/internal/obj/x86: use mov instead of lea to load the frame pointer This CL instructs the Go x86 compiler to load the frame pointer address using a MOV instead of a LEA instruction, being MOV 1 byte shorter: Before 55 PUSHQ BP 48 8d 2c 24 LEAQ 0(SP), BP After 55 PUSHQ BP 48 89 e5 MOVQ SP, BP This reduces the size of the Go toolchain ~0.06%.
