IV38082: DIS STOPS DISASSEMBLING WITH PWR7 INSTRUCTIONS

Subscribe

You can track all active APARs for this component.

APAR status

  • Closed as program error.

Error description

  • When disassembling a large object file with the 'dis'
    disassembler tool, the tool is ending mid-function, creating an
    incomplete, truncated *.s assembly output file.  POWER7
    instructions may be present in the function.
    

Local fix

  • Use DBX to disassemble.
    

Problem summary

  • PROBLEM DESCRIPTION:
    The disassembler encounters an internal error during the
    disassembly of a large object file containing POWER7
    instructions.
    
    USERS AFFECTED:
    Users with code containing a large number of PWR7 instructions
    

Problem conclusion

  • In the past, the disassembler utility could not recognize PWR7
    instructions without an arch option specified.  This change
    allows the disassembler to identify the arch by the C_FILE
    symbol/.machine information in the target object.  This, in
    turn, corrects the disassembly truncation issue seen.
    

Temporary fix
