LI76695: INLINE ASM ERROR WITH TR1 MEMORY HEADER FILE

XL C/C++ Advanced Edition for Blue Gene/P Fix Pack 17 (October 2013 Update) for 9.0
August 2012 Update for XL C/C++ Advanced Edition for Blue Gene/P, V9.0

APAR status

• Closed as program error.

Error description

• The following test case fails to compile with the BG compilers:
  
  ===== COMPILE COMMAND:
  xlC test.cpp
  
  ===== TESTCASE:
  $cat test.cpp
  #include <tr1/memory>
  
  int main(int argc, char** argv) {
  
  }
  $
  
  
  ===== ACTUAL OUTPUT:
  $ xlC test.cpp
  "/usr/include/c++/4.1.2/tr1/boost_shared_ptr.h", line 155.9:
  1540-0130 (S) "__volatile" is not declared.
  "/usr/include/c++/4.1.2/tr1/boost_shared_ptr.h", line 175.9:
  1540-0130 (S) "__volatile" is not declared.
  $
  
  ===== EXPECTED OUTPUT:
  Should compile clean
  

Local fix

• Since the XLC compiler doesn't understand the GCC styntax of
  __volatile, the workaround is to redefine it to something that
  XLC understands.
  
  $cat test.cpp
  #define __volatile volatile // defining __volatile to volatile
  
  with XLC compiler. But you shouldn't have to do this.
  #include <tr1/memory>
  
  int main(int argc, char** argv) {
  
  }$
  

Problem summary

• USERS AFFECTED:
  Customers using non-standard GCC keyword __volatile are
  affected by this issue.
  
  PROBLEM DESCRIPTION:
  The Linux compiler for C++ did not accept the __volatile
  keyword.
  

Problem conclusion

• The compiler has been fixed to accept the __volatile keyword.
  

Temporary fix
