Hi,
I would like to understand the structure of the parse tree generated
by Sparse a bit better. I am looking at the output from the show_*()
functions but it is not clear to me exactly what the output means. For
example:
extern int printf(const char *, ...);
int main(int argc, const char *argv[]) {
printf("hello world!\n");
return 0;
}
Results in:
.align 4
int extern [signed] [addressable] [toplevel] main( ... )
movi.64 v2,&"hello world!\n"
push.64 v2
call printf
add.64 vSP,vSP,$8
mov.32 v3,retval
movi.32 v4,$0
addi.64 v5,vFP,$offsetof(return:00000202755B1A98)
st.32 v4,[v5]
ret (00000202755B1A98)
.L00000202755B1A98:
addi.64 v6,vFP,$offsetof(return:00000202755B1A98)
ld.32 v7,[v6]
mov.32 retval,7
ret
I get the first four lines, but the rest don't make sense to me. I
suppose that the dump is trying to show the parse tree in a linear
form ... but is that useful? Would it be better to dump the parse
tree in a different form?
Regards
Dibyendu
