S390: For zero, let is_power_of_two() return false
|
|
|
0b42f8 |
|
|
|
0b42f8 |
This fixes a minor issue with the helper function is_power_of_two(),
|
|
|
0b42f8 |
which returned non-zero ("true") if the argument was zero. This led
|
|
|
0b42f8 |
to a wrong decision when passing a zero-sized struct in an inferior
|
|
|
0b42f8 |
function call.
