APAR status

• Closed as program error.

Error description

• The compiler produces an internal compiler error when using
  -qipa with the following test case:
  
  
  Compile Command:
  mpixlc -O3 -qipa -qhot -I/bgsys/drivers/ppcfloor/arch/include
  compiler_error.c compiler_error_include.c
  
  <<<<<<< Start of compiler_error_include.h>>>>>>>>>>>
  #include <mpi.h>
  
  MPI_Comm create_Inside_Node_Comm();
  <<<<<<<< End of compiler_error_include.h>>>>>>>>>
  
  <<<<<<<<<<<<< Start of compiler_error.c >>>>>>>>>>>>>
  #include "compiler_error_include.h"
  #include <mpi.h>
  
  int main(int argc, char **argv)
  {
  
      MPI_Init(&argc, &argv);
  
      MPI_Comm inside_comm;
  
      inside_comm = create_Inside_Node_Comm();
  
      MPI_Finalize();
  
  
      return 0;
  }

  {
      MPI_Comm inside_node_comm;
      _BGP_Personality_t personality;
  
      Kernel_GetPersonality(&personality, sizeof(personality));
  
      return inside_node_comm;

Local fix

• n/a
  

Problem summary

• Users of IPA with programs containing ASM statements which
  reference automatic variables that are contained in functions
  which are never called maybe affected by this issue.
  

Problem conclusion

• The fix was to allow for the removal of local symbols when
  importing ASM registry info table in IPA.
  

Temporary fix
