Dear TCC-Developers,
running some tests on tcc-0.9.25 I found an interesting behaviour concerning
postincrement.
Please consider the following little program:
#--------------------------------------------------
#include <stdio.h>
int main()
{
int i = 0, a[] = { -1, -1 };
a[i++] = i;
printf("%d %d\n", a[0], a[1]);
return 0;
}
#--------------------------------------------------
running it I expected the output to be:
0 -1
but indeed it is:
1 -1
Trying to understand the ANSI-C Standard, the evaluation sequence of the
assignment statement should be:
1. evaluate right side (since assignment is right associative) -> i = 0
2. calculate indix to "a" -> 0
3. assign 0 to a[0]
4. increment i
Am I wrong?
BTW: GCC, VC++, cc(HP-UX) do as I had expected; TCC and LCC do not, but do the
same.
TCC seems to be very nice. Thanks for your great work.
Best regards
Torsten Finke
