NOTE
The disassembler does not know which doen corresponds to loopstart3
, so ends up with an unmatched doen
instruction and prompts fatal error message. Disassembly is still possible if you omit the
f
command-line option.
14.3 ELF File Dump Utility
Use the Executable and Linking Format (ELF) file Dump Utility to output the headers of absolute and linkable object files in a human-readable format.
The information produced by the utility depends on the selected ELF object file type:
• Absolute (executable) -- Default output is ELF header, all program headers, and all sections headers.
• Linkable (relocatable) -- Default output is ELF header and all section headers.
To invoke the ELF dump utility from the command-line prompt, type: sc100-elfdump [option ...] <elf-file>
NOTE
The ELF dump utility is in this directory:

option
Table 14-3 defines the purpose and effect of each command-line option. Without options,
the utility returns the contents of the ELF Ehdr, Phdr, and Shdr structures and the symbol table. If you specify command-line options, the utility returns only the information that you specify on the command line.
NOTE
sc100-elfdump utility command-line options are case-sensitive.

The following listing shows the output of the ELF file dump utility.
NOTE
The file name is hello.eld
.
The ELF header extends from line e_ident
through line e_shstrndx
.
The program headers comprise lines
Segment 0
,
Segment 1
and their subordinate lines.
The section headers comprise the remaining lines.
