IV30171: INLINING FAILURE WITH BLOCKS OF DISJOINT CODE

APAR status

• Closed as fixed if next.

Error description

• With inlining enabled via -Q or -qinline, the compiler is
  encountering an internal compiler error, signal 11 or outputting
  message:
  
     1540-5210 (S) Insufficient memory
  
  During the compile, paging space for the xlCentry process
  reaches approximately 1500MB, then failure occurs.
  
  The code may contain a number of disjoint blocks of code denoted
  by {} brackets within a single function.
  

Local fix

• - Disable inlining with -qnoinline
  - Reduce code size by splitting functions into separate source
  files/compile units
  

Problem summary

• The insufficient memory issue is caused by the interaction
  between a large number of implicitly instantiated templates and
  the xlCentry function inliner behaviour.
  
  The issue has been identified and corrected in the V12.1 release
  of the compiler, but unfortunately this fix can not be
  backported to the V11.1 compiler, therefore this issue is a
  limitation in this release of the compiler.
  

Problem conclusion

Temporary fix
