If VFP is present, registers s16-s31 (a/k/a d8-d15, a/k/a q4-q7) must be preserved, s0-s15 (d0-d7, q0-a3) do not need to be. Stack is "full descending". Only the arguments that don't fit in the first 4 registers are placed on the stack. "sp" points at the first stacked argument (i.e. the 5th arg). VFP: single-precision results in s0, double-precision results in d0. In the EABI, "sp" must be 64-bit aligned on entry to a function, and any 64-bit quantities (long long, double) must be 64-bit aligned. */ /* Mterp and ARM notes: The following registers have fixed assignments: reg nick purpose r4 rPC interpreted program counter, used for fetching instructions r5 rFP interpreted frame pointer, used for accessing locals and args r6 rGLUE MterpGlue pointer r7 rINST first 16-bit code unit of current instruction r8 rIBASE interpreted instruction base pointer, used for computed goto Macros are provided for common operations.
