[PATCH] Fix seq_cost prototype to use signed int
- From: Jiong Wang <jiong dot wang at arm dot com>

- Subject: [PATCH] Fix seq_cost prototype to use signed int
- Authentication-results: sourceware.org; auth=none
All other cost helper functions are using signed int to hold cost
while seq_cost is using unsigned int.
This fix this. bootstrap OK on x86.
OK for trunk?

gcc/
* rtl.h (seq_cost): Change return type from "unsigned" to "int".
* rtlanal.c (seq_cost): Likewise.
