This patch compresses two lines into a single line if immediate return
is found. Variable rc is dropped as it is no longer needed.
Semantic patch used for this is as follows:
@@
type T;
identifier i,f;
constant C;
@@
- T i;
...when != i
when strict
(
return -C;
|
- i =
+ return
f(...);
- return i;
)
