- The compilation time under OPT(2) will be significantly less
than under Enterprise PL/I V3R2, especially for large programs.
- The compiler now uses the ED and EDMK instructions for inlined
numeric conversions to PICTURE and CHARACTER. This results in faster,
shorter code sequences and also in faster compilations.
- The compiler now generates better code for string comparisons.
This also results in faster, shorter code sequences.
- The compiler now generates shorter, faster code for conversion
from FIXED DECIMAL to PICTURE with trailing overpunch characters.
- The ARCH and TUNE compiler options now accept 5 as a valid
sub-option. Under ARCH(5), the compiler will generate, when appropriate,
some new
z/Architecture instructions such as NILL, NILH, OILL, OILH, LLILL,
and LLILH.
