Hi Dag,
I am currently looking at the tickets.
I was looking at this -
cdef int i, n
n = 10
for i in range(n):
if i == 5:
n *= 2
print i
The generated c code for this is -
__pyx_v_5test1_n = 10;
for (__pyx_v_5test1_i = 0; __pyx_v_5test1_i < __pyx_v_5test1_n;
__pyx_v_5test1_i+=1) {
__pyx_1 = (__pyx_v_5test1_i == 5);
if (__pyx_1) {
__pyx_v_5test1_n *= 2;
goto __pyx_L4;
}
__pyx_L4:;
}
Can the var 'n' be held in another temp variable?
Something like this -
__pyx_v_5test1_n = 10;
__pyx_v_5test1_const_n = 10;
for (__pyx_v_5test1_i = 0; __pyx_v_5test1_i < __pyx_v_5test1_const_n;
__pyx_v_5test1_i+=1) {
__pyx_1 = (__pyx_v_5test1_i == 5);
if (__pyx_1) {
__pyx_v_5test1_n *= 2;
goto __pyx_L4;
}
__pyx_L4:;
}
i--;
I haven't looked at the cython code which parses the loop and outputs the c
code. I would really appreciate if you can give me a head start into this
and correct me if I am wrong.
