| /* The main purpose of this file is dealing with prologues to extract |
| information about stack frames and saved registers. |
| |
| In gcc/config/mn13000/mn10300.c, the expand_prologue prologue |
| function is pretty readable, and has a nice explanation of how the |
| prologue is generated. The prologues generated by that code will |
| have the following form (NOTE: the current code doesn't handle all |
| this!): |
| |
| + If this is an old-style varargs function, then its arguments |
| need to be flushed back to the stack: |
| |
| mov d0,(4,sp) |
| mov d1,(4,sp) |
| |
| + If we use any of the callee-saved registers, save them now. |
| |
| movm [some callee-saved registers],(sp) |
| |
| + If we have any floating-point registers to save: |
| |
| - Decrement the stack pointer to reserve space for the registers. |
| If the function doesn't need a frame pointer, we may combine |
| this with the adjustment that reserves space for the frame. |
| |
| add -SIZE, sp |
| |
| - Save the floating-point registers. We have two possible |
| strategies: |
| |
| . Save them at fixed offset from the SP: |
| |
| fmov fsN,(OFFSETN,sp) |
| fmov fsM,(OFFSETM,sp) |
| ... |
| |
| Note that, if OFFSETN happens to be zero, you'll get the |
| different opcode: fmov fsN,(sp) |
| |
| . Or, set a0 to the start of the save area, and then use |
| post-increment addressing to save the FP registers. |
| |
| mov sp, a0 |
| add SIZE, a0 |
| fmov fsN,(a0+) |
| fmov fsM,(a0+) |
| ... |
| |
| + If the function needs a frame pointer, we set it here. |
| |
| mov sp, a3 |
| |
| + Now we reserve space for the stack frame proper. This could be |
| merged into the `add -SIZE, sp' instruction for FP saves up |
| above, unless we needed to set the frame pointer in the previous |
| step, or the frame is so large that allocating the whole thing at |
| once would put the FP register save slots out of reach of the |
| addressing mode (128 bytes). |
| |
| add -SIZE, sp |
| |
| One day we might keep the stack pointer constant, that won't |
| change the code for prologues, but it will make the frame |
| pointerless case much more common. */ |
| |
| /* Analyze the prologue to determine where registers are saved, |
| the end of the prologue, etc etc. Return the end of the prologue |
| scanned. |
| |
| We store into FI (if non-null) several tidbits of information: |
| |
| * stack_size -- size of this stack frame. Note that if we stop in |
| certain parts of the prologue/epilogue we may claim the size of the |
| current frame is zero. This happens when the current frame has |
| not been allocated yet or has already been deallocated. |
| |
| * fsr -- Addresses of registers saved in the stack by this frame. |
| |
| * status -- A (relatively) generic status indicator. It's a bitmask |
| with the following bits: |
| |
| MY_FRAME_IN_SP: The base of the current frame is actually in |
| the stack pointer. This can happen for frame pointerless |
| functions, or cases where we're stopped in the prologue/epilogue |
| itself. For these cases mn10300_analyze_prologue will need up |
| update fi->frame before returning or analyzing the register |
| save instructions. |
| |
| MY_FRAME_IN_FP: The base of the current frame is in the |
| frame pointer register ($a3). |
| |
| NO_MORE_FRAMES: Set this if the current frame is "start" or |
| if the first instruction looks like mov <imm>,sp. This tells |
| frame chain to not bother trying to unwind past this frame. */ |
