| |
Remove double checks, and move the call to print_error to the first check. The simplified version of the coccinelle semantic patch that fixes this issue is as follows:
// <smpl> @@ expression E; identifier pr; expression list es; @@ for(...;...;...){ ... - if (E) break; + if (E){ + pr(es); + break; + } ... } - if(E) pr(es); // </smpl>
Untested.
