APAR status
Closed as program error.
Error description
When compiling a program with multiple literals that are powers of 2, the optimizer transforms the program in a way that produces a faster compiled program but slows down the compiler when it does further optimizations.
Local fix
Compile at OPT(0) or ARCH(11) or substitute the literals with their product.
Problem summary
**************************************************************** * USERS AFFECTED: Users of Enterprise COBOL 6.4 compiling * * programs at OPT(1|2),ARCH(12) that have * * multiply a data item by multiple literals, * * where each literal is a power of 2. * **************************************************************** * PROBLEM DESCRIPTION: Program takes an excessive time to * * compile. * **************************************************************** * RECOMMENDATION: Apply the provided PTF * **************************************************************** When compiling a program with multiple literals that are powers of 2, the optimizer transforms the program in a way that produces a faster compiled program but slows down the compiler when it does further optimizations.
Problem conclusion
The compiler was fixed to perform further optimizations more efficiently after it expands the multiplications.
