+// Macros for transitioning from the host ABI to Go ABI0.
+//
+// These macros save and restore the callee-saved registers
+// from the stack, but they don't adjust stack pointer, so
+// the user should prepare stack space in advance.
+// SAVE_R19_TO_R28(offset) saves R19 ~ R28 to the stack space
+// of ((offset)+0*8)(RSP) ~ ((offset)+9*8)(RSP).
+//
+// SAVE_F8_TO_F15(offset) saves F8 ~ F15 to the stack space
+// of ((offset)+0*8)(RSP) ~ ((offset)+7*8)(RSP).
+//
+// R29 is not saved because Go will save and restore it.
