NAME

       fastbind - Prepare an incomplete executable for faster program start-up

SYNOPSIS

       incomplete-executable...

DESCRIPTION

       is  a  tool  that can improve the start-up time of programs that use shared libraries (incomplete executables) by storing information about
       needed shared library symbols in the executable file.

       performs analysis on the symbols used to bind an executable and all of it's dependent shared libraries, and stores this information in  the
       executable  file.   The next time the executable is run, the dynamic loader will notice that this information is available, and it will use
       this fastbind information to bind the executable instead of the standard search method for binding the symbols.	For Itanium-based systems,
       the dynamic loader is for 32-bit mode or for 64-bit mode.  For PA-RISC systems, the dynamic loader is for 32-bit mode or for 64-bit mode.

       Since  writes  the  fastbind  information in the executable file, you must have write permission on the executable file.  Also, if the exe-
       cutable file being analyzed is being run as another process, the file will be locked against modifications by the kernel, and will fail.

       If the shared libraries that an executable is dependent on are modified after the fastbind information is created, the dynamic loader  will
       silently  revert to standard search method for binding the symbols. The fastbind information can be re-created by running on the executable
       again.  will automatically erase the old fastbind information and generate the new one.

       The option can be used to instruct the linker to run the fastbind tool on an incomplete executable it has produced.

   Environment Variables
       If determines that the fastbind information is out of date, it will silently revert to standard search method for binding the  symbols.	If
       the environment variable is set to the dynamic loader will emit a warning message when the fastbind information is out of date.

       The  environment variable can be set to to make the dynamic loader ignore the fastbind information and revert to the standard search method
       for binding the symbols.

   Options
       recognizes the following options:

	      Remove the fastbind information from the executable, returning it to the
			  same state it was in before was originally run on it.

	      Normally, if
			  detects any unsatisfied symbols while building the fastbind information, it will generate an error message and not  mod-
			  ify the executable file.  When is invoked with option however, unresolved symbols are allowed.

DIAGNOSTICS

       returns zero when the operation is successful.  A non-zero return code indicates that an error occurred.

EXAMPLES

       To run on the executable file
	enter:

       To later remove the fastbind information from the executable file enter:

WARNINGS

       32-bit PA-RISC does not work with EXEC_MAGIC executables.

       effectively  enforces  bind restricted and bind immediate. For example, consider an executable linked bind deferred, which calls a function
       foo() defined in an implicitly loaded library. Before the actual call is made, if it explicitly loads a shared library (using  shl_load(3X)
       with  having  a definition for when is finally called, it will be resolved from the explicitly loaded library. But after running the symbol
       will be resolved from the implicitly loaded library.
