Error description

  • 1. Rename certain mnemonics and their associated extended
    mnemonics:
    
       Original  New       Extended
       --------  --------  -------------------------
    
       LGOC      LOCG      LOCGE    LOCGH    LOCGL
                           LOCGNE   LOCGNH   LOCGNL
    
       LGROC     LOCGR     LOCGRE   LOCGRH   LOCGRL

                           STOCGNE  STOCGNH  STOCGNL
    
    2. Add support for the CPU-Measurement Facility and the
       Load-Program-Parameter Facility, which became available on
       IBM System z10 (machine types 2097 and 2098), into UNI, ZS4
       and ZS5 opcode tables.  The following instructions have been
       added:
    
       ECCTR         ECPGA         EPCTR
       LCCTL         LPCTL         LPP
       LSCTL         QCTRI         QSI
       SCCTR         SPCTR
    
    3. Segmentation fault when executing on z/Linux with options
       FLAG(NOALIGN,PAGE0) and the assembler attempts to generate
       diagnostic ASMA309W.
    
    
    Publication SA23-2260 at this URL documents the CPU-
    Measurement Facility:
    
    http://publibfi.boulder.ibm.com/epubs/pdf/a2322600.pdf
    
    Note that this document is slightly out of date with
    regards to the mnemonics.  The document makes reference
    to the following mnemonics: ECA, SPP, SCCTL, SPCTL and
    SSCTL, which have been renamed to: ECPGA, LPP, LCCTL,
    LPCTL and LSCTL respectively.

Problem conclusion

Temporary fix

Comments

  • The High Level Assembler has been modified to:
    1. Recognize renamed mnemonics.
    2. Support the CPU-Measurement Facility and the Load-Program-
       Parameter Facility.
    3. Avoid faulting on z/Linux with options FLAG(NOALIGN,PAGE0).
