APAR status

• Closed as program error.

Error description

• A compiler warning is encountered when a simple test case is
  compiled with '-qipa -qinlglue'.
  
  This warning message is generated by a particular component of
  the compiler that is not responsible for implementing
  '-qinlglue'. The implementation of this option is
  successfully handled by the low level optimizer despite the
  warning message that is generated by the high level optimizer.
  
  ===== TESTCASE:
  hello.c:
  #include <stdio.h>
  
  int main ()
  {
          printf("%s\n", "Hello, world!");
          return 0;
  }
  =========================================
  
  
  ===== ACTUAL OUTPUT:
  $ xlc -q64 -qipa -qinlglue hello.c
  1586-002 (W) Suboption "" of option "" is not supported.
  1586-001 (W) Option "-qinlglue" is not valid.
  $
  
  
  ===== EXPECTED OUTPUT:
  Compilation completes without warning message.
  
  $ xlc -q64 -qipa -qinlglue hello.c
  $
  

Local fix

• N/A.
  

Problem summary

• PROBLEM DESCRIPTION:
  Compiler warning with -qipa -qinlglue
  
  USERS AFFECTED:
  Users of optimization levels -O3 or higher.
  

Problem conclusion

• The high level optimizer is not responsible for implementing
  '-qinlglue' and is incorrectly generating this warning message.
  The fix just involves having the high level optimizer recognize
  that -qinlglue and -qnoinlglue are valid compiler options.
  

Temporary fix
