@ Check for .setfp directive.
|
|
|
|
@ The .setfp directive will track the offset between the frame pointer and
|
|
@ the stack pointer. This is required for the function that will change
|
|
@ the stack pointer out of the function prologue. If the exception is thrown,
|
|
@ then libunwind will reconstruct the stack pointer from the frame pointer.
|
|
@ The reconstruction code is implemented by two different unwind opcode:
|
|
@ (i) the unwind opcode to copy stack offset from the other register, and
|
|
@ (ii) the unwind opcode to add or subtract the stack offset.
|
|
@
|
|
@ This file includes several cases separated by different range of -offset
|
|
@
|
|
@ (-offset) < 0x00
|
|
@ (-offset) == 0x00
|
|
@ 0x04 <= (-offset) <= 0x100
|
|
@ 0x104 <= (-offset) <= 0x200
|
|
@ 0x204 <= (-offset)
