Bug#229567: gcc-3.3: Miscompile with -O -funroll-loops on powerpc
Package: gcc-3.3
Version: 1:3.3.3-0pre2
Severity: normal
When complied with -O -funroll-loops on powerpc, the attached test.i
produces the following output:
Bytes in main: 0 1
Bytes in: 0 1 0 1 0 1 ( 0 10 15 254)
x = 282
Bytes in: 0 1 0 1 0 1 ( 94 52 15 254)
x = 418
Bytes in: 0 1 0 1 0 1 ( 7 208 15 254)
x = 487
The reported x's should be the sum of the first six numbers on the line
above. Instead, it is the sum of _all_ the numbers on the line above.
Changing -O to -O2, or removing -funroll-loops generates the following
(correct) result:
Bytes in main: 0 1
Bytes in: 0 1 0 1 0 1 ( 70 148 15 234)
x = 3
Bytes in: 0 1 0 1 0 1 ( 0 10 15 254)
x = 3
Bytes in: 0 1 0 1 0 1 ( 7 76 15 234)
x = 3
On 386, this problem does not occur.
Note that this could be the same bug as PR13222, in which case this would
be a nice, small, test case. I have not actually looked at the test case
in PR13222 however, since it is rather large.
The result of
gcc -v --save-temps -O -funroll-loops test.c 2> ~/output.txt
is below:
