.TH MCPU-OBJDUMP 1 "October 2026" "LibMCPU" "User Commands"
.SH NAME
mcpu-objdump \- display sections, relocations and MCPU instructions
.SH SYNOPSIS
.B mcpu-objdump
.RI [ options ] " MELF-file(s)"
.SH DESCRIPTION
.B mcpu-objdump
inspects MELF objects, executables, shared objects and deterministic archives.
Its disassembler uses the same LibMCPU instruction decoder used by execution,
so the toolchain does not maintain a second ISA parser. Symbol and relocation
information is used to annotate disassembly without rewriting raw operand bytes.
.SH OPTIONS
.TP
.BR -d ", " --disassemble
Disassemble executable PROGBITS sections.
.TP
.BR -D ", " --disassemble-all
Attempt disassembly of all selected nonempty PROGBITS sections.
.TP
.BR -r ", " --reloc
Display relocation entries. During disassembly, relocations are associated
with the instruction containing the relocated field; relocations from other
sections remain visible as tables.
.TP
.BR -s ", " --full-contents
Display raw contents of selected sections.
.TP
.BR -t ", " --syms
Display .symtab symbols.
.TP
.BR -T ", " --dynamic-syms
Display .dynsym symbols.
.TP
.BR -h ", " --section-headers
Display section headers.
.TP
.BI -j " NAME"
.TQ
.BI --section= NAME
Restrict section-oriented output to NAME. Repeatable.
.TP
.B --help
Display help and exit.
.TP
.B --version
Display the program name, MCPU toolchain identity and version, then exit.
.TP
.B --dump-version
Display only the MCPU package version number and exit.
.PP
At least one display option is required. Undecodable bytes are printed as
.byte data and inspection continues.
.SH EXIT STATUS
Zero on successful inspection; nonzero for invalid options or malformed input.
.SH EXAMPLES
.nf
mcpu-objdump -h file.o
mcpu-objdump -t -r -d file.o
mcpu-objdump -T -d -r libfoo.so.1
mcpu-objdump -s -j .data file.o
mcpu-objdump -d libsimple.a
.fi
