Chapter 1 13
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.
+cfc Flag
The +cfc flag has been added to the Fortran compiler. +cfc allows you access to the 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 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.
