Is TinyCC ARM prolog :
mov ip, sp
stmdb sp!, {fp, ip, lr}
add fp, sp, #C
compatible with this ?
From Microsoft http://msdn.microsoft.com/en-us/library/ms254231.aspx
The following examples show how to construct several ARM prologs.
ARM Prolog with frame in R11.
MOV r12, r13 ; Save stack on entry if needed.
STMDB r13!, {r0-r3} ; As needed
STMDB r13!, {r4-r12, r14} ; As needed
SUB r11, r12, #16 ; Sets frame past args
<stack link if needed>
MOV r12, r13 ; Save stack on entry if needed.
STMDB r13!, {r0-r3} ; As needed
STMDB r13!, {r4-r12, r14} ; As needed
SUB r11, r12, #16 ; Sets frame past args
<stack link if needed>
ARM Prolog with no frame.
MOV r12, r13
STMDB r13!, {r0-r3} ; As needed
STMDB r13! {[r4-r12,]|[r13,]r14} ; As needed
<stack link if needed>
<note: r12 is not used if the stack (r13) is the first register saved>
