Error description
The compiler may generate a branch instruction for the CONTINUE or EXIT statement that is unreachable from any other instruction, causing code coverage tools to incorrectly report that the line isn't covered
Local fix
Compile at OPT(1|2)
Problem summary
**************************************************************** * USERS AFFECTED: Users of Enterprise COBOL V6.2 compiling * * programs at OPT(0) that have an IF * * statement where a CONTINUE or EXIT * * statement is the only statement in the body * * of an ELSE clause. * **************************************************************** * PROBLEM DESCRIPTION: The compiler may generate a branch * * instruction for the CONTINUE or EXIT * * statement that is unreachable from any * * other instruction, causing code * * coverage tools to incorrectly report * * that the line isn't covered. * **************************************************************** * RECOMMENDATION: Apply the provided PTF. * **************************************************************** The optimizer was changing a branch to another branch instruction, redirecting the first branch to the final destination. However, since the compiler guarantees that there will be an instruction generated for every line of COBOL code, the second branch statement could persist but be unreachable.
Problem conclusion
The optimizer was fixed to not redirect one branch to another at OPT(0) unless both branch instructions are generated for the same line of COBOL source.
Temporary fix
