What’s in This Version

The HP Fortran v2.9 compiler has been significantly enhanced with many Tru64 Fortran

features (detailed below). Additionally, a new and improved high-level optimizer was added.

Compile-time performance is expected to improve for source files that experienced large slow

down in compilation speed at optimization level +O3.

In addition, Fortran v2.9 contains object-oriented feature optimizations, including:

• Full Fortran 95 compiler (based on International ANSI/ISO standards)

• Other new or revised directives/options

+O[no]failsafe

+allow_ivdep

+Ofaster

-ipo

optimize openmp [on|off]

+Oautopar

+Ofast

+DOosname

+Oprofile=collect

HP$OPTIMIZE

•BinaryI/Oconversions

• Resolving issues with unaligned data

• Full OpenMP v2.0

• Linking HP Fortran 90 routines

• Support for the HP WDB Debugger

• HP Caliper v3.5

• Support for math intrinsic inlining

• Standard Fortran library

New Tru64 Fortran features (valid for 11.23 on both Itanium -based

and PA-RISC systems)

Support has been added for options that will assist users in porting applications from Tru64

to HP Fortran. Wherever possible, these options mimic the behavior of their counterparts in

the Tru64 Fortran compiler.
