NAME

       pbc_merge - Merge multiple Parrot bytecode (PBC) files into
                         a single PBC file.


SYNOPSIS

        pbc_merge -o out.pbc input1.pbc input2.pbc ...


DESCRIPTION

       This program takes two or more PBC files and produces a single merged
       output PBC file with a single fix-up table and constants table.

   Command-Line Options
       "-o out.pbc"
           The name of the PBC file to produce, containing the merged segments
           from the input PBC files.

       "-?" or "--help"

   Functions
       "static void help(void)"
           Prints usage info.

       "static void ensure_libdep(PARROT_INTERP, PackFile_ByteCode *bc, STRING
       *lib)"
           Ensures that the libdep "lib" is in the libdeps list for "bc".

       "static PackFile_ByteCode* pbc_merge_bytecode(PARROT_INTERP,
       pbc_merge_input **inputs, int num_inputs, PackFile *pf)"
           This function merges the bytecode from the input packfiles, storing
           the offsets that each bit of bytecode now exists at.

       "static PackFile_ConstTable* pbc_merge_constants(PARROT_INTERP,
       pbc_merge_input **inputs, int num_inputs, PackFile *pf)"
           This function merges the constants tables from the input PBC files.

       "static PackFile_Annotations* pbc_merge_annotations(PARROT_INTERP,
       pbc_merge_input **inputs, int num_inputs, PackFile *pf,
       PackFile_ByteCode *bc)"
           Merge Annotations segments from "inputs" into a new
           "PackFile_Annotations" segment. Returns the new merged segment
           (which is also already appended to the directory in "pf").

       "static void pbc_merge_debugs(PARROT_INTERP, pbc_merge_input **inputs,
       int num_inputs, PackFile_ByteCode *bc)"
           This function merges the debug segments from the input PBC files.

       "static void pbc_fixup_bytecode(PARROT_INTERP, pbc_merge_input
       **inputs, int num_inputs, PackFile_ByteCode *bc)"
           Fixup bytecode. This includes correcting pointers into the constant
           table and updating the ops mapping.

       "static void pbc_fixup_constants(PARROT_INTERP, pbc_merge_input
       **inputs, int num_inputs)"
           Fixup constants. This includes correcting pointers into bytecode.

       "static PackFile* pbc_merge_begin(PARROT_INTERP, pbc_merge_input
       **inputs, int num_inputs)"
           This is the function that drives PBC merging process.

       "static void pbc_merge_write(PARROT_INTERP, PackFile *pf, const char
       *filename)"
           This functions writes out the merged packfile.

       "int main(int argc, const char **argv)"
           The main function checks arguments, reads in the packfiles provided
           they exist, call the merge functions and writes out the produced
           packfile.
