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.
Functions
"static void help(PARROT_INTERP)"
Print out the user help info.
"static PackFile* pbc_merge_loadpbc(PARROT_INTERP, const char
*fullname)"
This function loads a PBC file and unpacks it. We can’t use
Parrot_pbc_read because that is specified to also fixup the
segments, which we don’t want.
"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,
PackFile_ByteCode *bc)"
This function merges the constants tables from the input PBC files.
"static void pbc_merge_fixups(PARROT_INTERP, pbc_merge_input **inputs,
int num_inputs, PackFile *pf)"
This function merges the fixups tables from the input PBC files.
"static void pbc_merge_debugs(PARROT_INTERP, pbc_merge_input **inputs,
int num_inputs, PackFile *pf, PackFile_ByteCode *bc)"
This function merges the debug segments from the input PBC files.
"static void pbc_merge_ctpointers(PARROT_INTERP, pbc_merge_input
**inputs, int num_inputs, PackFile_ByteCode *bc)"
This function corrects the pointers into the constants table found
in the 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 that grabs console input, reads in the packfiles
provided they exist, hands them to another function that runs the
merge process and finally writes out the produced packfile.
