FSPLIT(1) General Commands Manual FSPLIT(1)NAME
fsplit - split a multi-routine Fortran file into individual files
fsplit [ -e efile] ... [ file ]
Fsplit takes as input either a file or standard input containing Fortran source code. It attempts to split the input into separate routine
files of the form name.f, where name is the name of the program unit (e.g. function, subroutine, block data or program). The name for
unnamed block data subprograms has the form blkdtaNNN.f where NNN is three digits and a file of this name does not already exist. For
unnamed main programs the name has the form mainNNN.f. If there is an error in classifying a program unit, or if name.f already exists,
the program unit will be put in a file of the form zzzNNN.f where zzzNNN.f does not already exist.
Normally each subprogram unit is split into a separate file. When the -e option is used, only the specified subprogram units are split
into separate files. E.g.:
fsplit -e readit -e doit prog.f
will split readit and doit into separate files.
If names specified via the -e option are not found, a diagnostic is written to standard error.
Asa Romberger and Jerry Berkman
Fsplit assumes the subprogram name is on the first noncomment line of the subprogram unit. Nonstandard source formats may confuse fsplit.
It is hard to use -e for unnamed main programs and block data subprograms since you must predict the created file name.

GNATELIM(1) ASIS Tools GNATELIM(1)NAME
gnatelim - eliminate dead code from Ada programs
gnatelim [OPTION]... name
When you are working with a program which shares some set of Ada packages with other programs, it may happen, that your program uses only a
part of subprogram defined in these packages, whereas the code created for unused subprograms increases the size of the executable your
gnatelim is a utility tracking unused subprograms in an Ada program. Its output consists of a list of Eliminate pragmas marking all the
subprograms that are declared, but never called in a given program. Eliminate is a GNAT-specific pragma. By ecompiling your program with
these pragmas, you may decrease the size of its executable, because the compiler will not create the code for unused subprograms.
gnatelim is an ASIS application developed on top of the ASIS implementation for GNAT. It needs a set of tree files representing a program
to analyze and the bind file for its main subprogram to be created in the current directory. For the current version, it is a the user's
responsibility to maintain the consistency of the set of tree files processed by gnatelim, if the user also changes the sources of the Ada
program to be processed.
To produce a list of Eliminate pragmas, gnatelim has to do an extensive analysis and it may take some time. For example, to process itself,
gnatelim takes 4 minutes of CPU time on a Pentium 200.
OPTIONS -v verbose mode: gnatelim version information is printed (in the form of Ada comments) in stdout; the names of the files being pro-
cessed are printed to standard-error.
-vf Same as -v, but in addition various debugging information and information reflecting some details of the analysis done by gnatelim
are printed to standard-error.
-a Process RTL components: by default, gnatelim does not analyze the units which are the components of the GNAT Run-Time Library (RTL),
and it does not generate Eliminate pragmas for subprograms declared in the RTL. If '-a' option is set, RTL components are also ana-
lyzed (except some units, which contains subprograms implicitly called by the compiler).
-m Check missed units: if this option is set, gnatelim checks that all the units which (according to the bind file) has to be analyzed
by gnatelim are really represented by the set of tree files processed by gnatelim (depending on whether or not '-a' option is set).
By default (that is, if '-m' option is not set), gnatelim analyzes a set of units represented by a given set of tree files "as is"
(excluding library packages which require bodies, but for which bodies are not available).
ASIS-for-GNAT was originally developed by the ASIS-for-GNAT team at the Software Engineering Laboratory of the Swiss Federal Insti-
tute of Technology (LGL-EPFL) in Lausanne, Switzerland, in cooperation with the Scientific Research Computer Center of Moscow State
University (SRCC MSU), Russia, with funding partially provided by grants from the Swiss National Science Foundation and the Swiss
Academy of Engineering Sciences. ASIS-for-GNAT is now maintained by Ada Core Technologies Inc (http://www.gnat.com).
