-=head1 NAME
-
-llvm2xpp - LLVM bitcode to LLVM C++ IR translator
-
-=head1 SYNOPSIS
-
-B<llvm2cpp> [I<options>] [I<filename>]
-
-=head1 DESCRIPTION
-
-B<llvm2cpp> translates from LLVM bitcode (.bc files) to a
-corresponding C++ source file that will make calls against the LLVM C++ API to
-build the same module as the input. By default, the C++ output is a complete
-program that builds the module, verifies it and then emits the module as
-LLVM assembly. This technique assists with testing because the input to
-B<llvm2cpp> and the output of the generated C++ program should be identical.
-
-If F<filename> is omitted or is C<->, then B<llvm2cpp> reads its input from
-standard input.
-
-If an output file is not specified with the B<-o> option, then
-B<llvm2cpp> sends its output to a file or standard output by following
-these rules:
-
-=over
-
-=item *
-
-If the input is standard input, then the output is standard output.
-
-=item *
-
-If the input is a file that ends with C<.bc>, then the output file is of
-the same name, except that the suffix is changed to C<.cpp>.
-
-=item *
-
-If the input is a file that does not end with the C<.bc> suffix, then the
-output file has the same name as the input file, except that the C<.cpp>
-suffix is appended.
-
-=back
-
-=head1 OPTIONS
-
-=over
-
-=item B<-f>
-
-Force overwrite. Normally, B<llvm2cpp> will refuse to overwrite an
-output file that already exists. With this option, B<llvm2cpp>
-will overwrite the output file and replace it with new C++ source code.
-
-=item B<--help>
-
-Print a summary of command line options.
-
-=item B<-f>
-
-Normally, B<llvm2cpp> will not overwrite an existing output file. With this
-option, that default behavior is changed and the program will overwrite existing
-output files.
-
-=item B<-o> F<filename>
-
-Specify the output file name. If F<filename> is C<->, then B<llvm2cpp>
-sends its output to standard output.
-
-=item B<-funcname> F<functionName>
-
-Specify the name of the function to be generated. The generated code contains a
-single function that produces the input module. By default its name is
-I<makeLLVMModule>. The B<-funcname> option overrides this default and allows
-you to control the name of the generated function. This is handy in conjunction
-with the B<-fragment> option when you only want B<llvm2cpp> to generate a
-single function that produces the module. With both options, such generated code
-could be I<#included> into another program.
-
-=item B<-for>
-
-Specify the name of the thing for which C++ code should be generated. By default
-the entire input module is re-generated. However, use of the various B<-gen-*>
-options can restrict what is produced. This option indicates what that
-restriction is.
-
-=item B<-gen-program>
-
-Specify that the output should be a complete program. Such program will recreate
-B<llvm2cpp>'s input as an LLVM module, verify that module, and then write out
-the module in LLVM assembly format. This is useful for doing identity tests
-where the output of the generated program is identical to the input to
-B<llvm2cpp>. The LLVM DejaGnu test suite can make use of this fact. This is the
-default form of generated output.
-
-If the B<-for> option is given with this option, it specifies the module
-identifier to use for the module created.
-
-=item B<-gen-module>
-
-Specify that the output should be a function that regenerates the module. It is
-assumed that this output will be #included into another program that has already
-arranged for the correct header files to be #included. The function generated
-takes no arguments and returns a I<Module*>.
-
-If the B<-for> option is given with this option, it specifies the module
-identifier to use in creating the module returned by the generated function.
-
-=item B<-gen-contents>
-
-Specify that the output should be a function that adds the contents of the input
-module to another module. It is assumed that the output will be #included into
-another program that has already arranged for the correct header files to be
-#included. The function generated takes a single argument of type I<Module*> and
-returns that argument. Note that Module level attributes such as endianess,
-pointer size, target triple and inline asm are not passed on from the input
-module to the destination module. Only the sub-elements of the module (types,
-constants, functions, global variables) will be added to the input module.
-
-If the B<-for> option is given with this option, it specifies the module
-identifier to set in the input module by the generated function.
-
-=item B<-gen-function>
-
-Specify that the output should be a function that produces the definitions
-necessary for a specific function to be added to a module. It is assumed that
-the output will be #included into another program that has already arranged
-for the correct header files to be #included. The function generated takes a
-single argument of type I<Module*> and returns the I<Function*> that it added to
-the module. Note that only those things (types, constants, etc.) directly
-needed in the definition of the function will be placed in the generated
-function.
-
-The B<-for> option must be given with this option or an error will be produced.
-The value of the option must be the name of a function in the input module for
-which code should be generated. If the named function does not exist an error
-will be produced.
-
-=item B<-gen-inline>
-
-This option is very analagous to B<-gen-function> except that the generated
-function will not re-produce the target function's definition. Instead, the body
-of the target function is inserted into some other function passed as an
-argument to the generated function. Similarly any arguments to the function must
-be passed to the generated function. The result of the generated function is the
-first basic block of the target function.
-
-The B<-for> option works the same way as it does for B<-gen-function>.
-
-=item B<-gen-variable>
-
-Specify that the output should be a function that produces the definitions
-necessary for a specific global variable to be added to a module. It is assumed
-that the output will be #included into another program that has already arranged
-for the correct header files to be #included. The function generated takes a
-single argument of type I<Module*> and returns the I<GlobalVariable*> that it
-added to the module. Note that only those things (types, constants, etc.)
-directly needed in the definition of the global variable will be placed in the
-generated function.
-
-The B<-for> option must be given with this option or an error will be produced.
-THe value of the option must be the name of a global variable in the input
-module for which code should be generated. If the named global variable does not
-exist an error will be produced.
-
-=item B<-gen-type>
-
-Specify that the output should be a function that produces the definitions
-necessary for specific type to be added to a module. It is assumed that the
-otuput will be #included into another program that has already arranged for the
-correct header files to be #included. The function generated take a single
-argument of type I<Module*> and returns the I<Type*> that it added to the
-module. Note that the generated function will only add the necessary type
-definitions to (possibly recursively) define the requested type.
-
-The B<-for> option must be given with this option or an error will be produced.
-The value of the option must be the name of a global type in the input module
-for which code should be generated. If the named type does not exist an error
-will be produced.
-
-=item B<-stats>
-
-Show pass statistics (not interesting in this program).
-
-=item B<-time-passes>
-
-Show pass timing statistics (not interesting in this program).
-
-=item B<-version>
-
-Show the version number of this program.
-
-=back
-
-
-=head1 EXIT STATUS
-
-If B<llvm2cpp> succeeds, it will exit with 0. Otherwise, if an error
-occurs, it will exit with a non-zero value.

-
-=head1 NOTES
-
-This tool may be removed from a future version of LLVM. Instead, its
-functionality may be incorporated into the llc tool. It would then act similarly
-to other targets except its output would be C++ source that could be compiled to
-construct the input program.
