HP Fortran v2.9 for HP-UX 11i v2 Release Note5991-0697

HP Fortran for HP-UX v2.9

What’s in This Version

Chapter 1 11

+DOosname

• Sets the target operating system for the compiler.

• Intended for enabling optimizations that are not backward compatible.

• Can be used at any level of optimization.

• PA-RISC—based system recognized values for osname are 11.0 and 11.0EP9806.

Itanium

—based system recognized values for osname are 11.20, 11.22, and 11.23.

+DOosname selects optimizations that are compatible with operating system version

osname and later.

• Default value for osname is the operating system version of the computer on which the

compiler is invoked.

+Oprofile=collect[:<qualifiers>]

In the absence of qualifiers, +Oprofile=collect is the same as +I. <qualifiers> are a

comma-separated list of profile collection qualifiers. Supported profile collection qualifiers:

• arc—collect arc counts (synonym for +Oprofile=collect). This is the default value.

• stride—collect stride data.

• all—collect all types of profile data. This is a synonym for +Oprofile-collect:arc,

stride.

Interactions and dependencies are not changed with respect to +Oprofile=collect.

$HP$ OPTIMIZE

HP$ OPTIMIZE, as listed below, is now supported for Fortran 90.

• !$HP$ OPTIMIZE ON

• !$HP$ OPTIMIZE OFF

• !$HP$ OPTIMIZE level 1

• !$HP$ OPTIMIZE level 0

• !$HP$ OPTIMIZE level 2

• !$HP$ OPTIMIZE level 1 on

• !$HP$ OPTIMIZE level 0 on
