LI80897: INTERNAL COMPILER ERROR WITH SIMDIZABLE CODE

APAR status

• Closed as program error.

Error description

• An internal compiler error occurs when compiling code that is
  potentially SIMDizable with optimization enabled.  The
  optimization level used is -O3 and up, implying that the -qsimd
  option is enabled.
  
  The error message output looks like:
  
  1500-004: (U) INTERNAL COMPILER ERROR while compiling
  my_function(double *, char *).  Compilation ended.  Contact
  your Service Representative and provide the following
  information: Internal abort. For more information visit:
  http://www.ibm.com/support/docview.wss?uid=swg21110810
  1586-346 (U) An error occurred during code generation.  The code
  generation return code was 1.
  

Local fix

• None.  Use lower optimization level.
  

Problem summary

• PROBLEM DESCRIPTION:
  An internal compiler error is encoutered when compiling with -g
  debug information and optimization enabled.  Internal code
  movement of debug information caused by optimization is putting
  the compiler in an error state.
  
  USERS AFFECTED:
  Users compiling with -g and optimization
  

Problem conclusion

• The compiler was corrected to avoid the error state.
  

Temporary fix
