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 5

+cfc

The +cfc flag has been added to the Fortran compiler. +cfc allows you access to the

newly-implemented Tru64 Fortran options.You can call them in one of two ways:

/opt/fortran90/tru64/f90

opt/fortran90/bin and then place +cfc in the command line

It is important to note that +cfc requires the following runtime library patches to function

properly:

• PHSS_31970—liblO77 11.22/11.23 0409

• PHSS_31971—libcl 11.11

• PHSS_31972—libcl 11.23 0409 (also pa-sharelibs for use through aries)

• PHSS_31973—libF90 11.22/11.23 0409

• PHSS_31974—libF90 11.11

NOTE +cfc will not work without the patches listed above.

Enhancements

The following enhancements have been made to support the addition of new Tru64 Fortran

options:

• Added CLF_TRU64 bit to command-line flags, used to distinguish migration options from

‘regular’ options.

• Added support for CLF_DETACHED_SUB_OPT bit in command-line flags, used to indicate

flags with a space-delimited sub-option (-foo bar), not to be confused with flags that take a

space-separated argument.

• Added TRU64DRIVER as new (pseudo-) phase in the f90 driver.

• Added/updated Compaq-mode determination code in driver. Now done early in main(), in

case other driver components need to know the state of compaq_flag prior to standard

options processing.

• Added support for Compaq-mode defaults to be emitted, when they differ from HP-mode.

• Added ‘-align’optiontomaintable;createdtru64_align_flags table for sub-options.

•Madeallnew-align options conflict with existing +A and +allow_unaligned options.
