All source files that reference variables in such a common block must be
compiled with the +indirectcommonlist flag, and that common
block name must appear in the named file.
Default initialization of heap variables (mentioned in +initheap_set option)
of type complex. rval is real part and ival is imaginary part of complex

number. Valid values for rval and ival are normal real numbers, nan ,
snan.
The numbers represented by rval/ival are mentioned in below table.

snan is supported at default optimization level only.
Default initialization of heap variables (mentioned in +initheap_set option)
of type integer. Valid values of ival are integer values of the form decimal,
octal (starting with 0) and hexadecimal (starting with 0x).

Default initialization of heap variables (mentioned in +initheap_set option)
of type real. Valid values for rval are normal real numbers, nan, snan.

Default Initialization of heap variables is done for the variables specified
by var.
+initheap_set=var
The defined values for var are:

A combination of different type of heap variables can be specified by
colon separated values, like +initheap_set=common:module:save
The default is +initheap_set=none
Suppresses the generation of the optional leading “0” before the decimal
point for real numbers printed with the E and F edit descriptors. Fortran
+io77
77 suppressed these leading zeros unless the NOSTANDARDIOflag was
used.
This option is only valid for Itanium processor family architectures.-ipo
Enables interprocedural optimizations across files. Object files produced
using this option contain intermediate code in IELFformat. At link time,
ldautomatically invokes the interprocedural optimizer u2compif any of
the input object files is an IELFfile. This option is ignored at optimization
