Problem description

The following problems regarding gcc have been fixed by using IBM patches gcc-2.95.3-s390-3.tar.gz (IBM code drop 2002-03-18) and gcc-2.95.4-4.tar.gz:
  • Incorrect code generated by the loop optimizer. In some very rare cases the strength reduction pass would generate incorrect code.
  • Application crashes when throwing an exception. In functions using variable argument lists DWARF-2 information used by the exception handling unwinding code was incorrectly generated causing an abort of the application.
  • Internal compiler error on long long multiplications for 31-bit target
  • 64-bit instructions generated on 31-bit (tmll instructions in 31-bit assembler code)
  • Incorrect code generated due to using ADD instruction instead of LOAD ADDRESS for pointer computation.
  • Incorrect code generated by inline memcpy
  • Dead code elimination for complex switch statements removes code following the switch statement as well when all cases prove to contain dead code.
  • Internal compiler error "unrecognized insn" due to illegal address constants.
