What is New in This Version
This section gives an overview of the new features introduced in this version of the HP
Fortran compiler.
New Features in Version 3.1.2
HP Fortran version 3.1.2 provides the following new features:
New Pragma $HP$ ESTIMATED FREQUENCY
The $HP$ ESTIMATED FREQUENCY block-scoped pragma allows the user to pass on to the
compiler an estimate of how frequently the current block is executed. If the current block is an
'if' block, then 'f' must be 0 <= f <= 1. In this case, 'f' indicates the probability of executing this
block compared to the corresponding 'if' block. If the current block is a loop, then 'f' must be
f >= 0. In this case, 'f' indicates the number of times the loop might get executed (trip count).
