perf tools: Bool functions shouldn't return -1 ...
Returning a negative value for a boolean function seem to have the
undesired effect of returning true. Replace -1 by false in a
bool-returning function.
The diff of the .s file before and after the change (for x86_64):
3907c3907
< movl $1, %ebx
---
> xorl %ebx, %ebx
while if -1 is replaced by true, the diff is empty.
This issue was found by the following Coccinelle semantic patch:
<smpl>
@@
identifier f;
constant C;
typedef bool;
@@
bool f (...){
<+...
* return -C;
...+>
}
</smpl>
