enum frame_type type;
CORE_ADDR return_pc
int leaf_function
If the compilation option -fno-omit-frame-pointer is present the
variable frame will be set to the content of R8 which is the frame
pointer register.
The variable pc contains the address where execution is performed
in the present frame. The innermost frame contains the current content
of the register PC. All other frames contain the content of the
register PC in the next frame.
The variable `type' indicates the frame's type: normal, SIGTRAMP
(associated with a signal handler), dummy (associated with a dummy
frame).
The variable return_pc contains the address where execution should be
resumed when the present frame has finished, the return address.
The variable leaf_function is 1 if the return address is in the register
SRP, and 0 if it is on the stack.
Prologue instructions C-code.
The prologue may consist of (-fno-omit-frame-pointer)
1) 2)
push srp
push r8 push r8
move.d sp,r8 move.d sp,r8
subq X,sp subq X,sp
movem rY,[sp] movem rY,[sp]
move.S rZ,[r8-U] move.S rZ,[r8-U]
where 1 is a non-terminal function, and 2 is a leaf-function.
Note that this assumption is extremely brittle, and will break at the
slightest change in GCC's prologue.
If local variables are declared or register contents are saved on stack
the subq-instruction will be present with X as the number of bytes
needed for storage. The reshuffle with respect to r8 may be performed
with any size S (b, w, d) and any of the general registers Z={0..13}.
The offset U should be representable by a signed 8-bit value in all cases.
Thus, the prefix word is assumed to be immediate byte offset mode followed
by another word containing the instruction.
Degenerate cases:
3)
push r8
move.d sp,r8
move.d r8,sp
pop r8
Prologue instructions C++-code.
Case 1) and 2) in the C-code may be followed by
move.d r10,rS ; this
move.d r11,rT ; P1
move.d r12,rU ; P2
move.d r13,rV ; P3
move.S [r8+U],rZ ; P4
if any of the call parameters are stored. The host expects these
instructions to be executed in order to get the call parameters right. */
/* Examine the prologue of a function. The variable ip is the address of
the first instruction of the prologue. The variable limit is the address
of the first instruction after the prologue. The variable fi contains the
information in struct frame_info. The variable frameless_p controls whether
the entire prologue is examined (0) or just enough instructions to
determine that it is a prologue (1). */
