APAR status

• Closed as program error.

Error description

• Source that makes use of inline assembly is hitting an error in
  the assembler due to invalid instruction syntax.
  
  
     === TEST CASE ===
  
  extern __thread int x, *p;
  
  void  mytest(void **fp)
  {
    __asm ("ori %0, 1, 0" : "=r" (*(&fp)));
    p = &x;
  }
  
  
  $ xlc -q64 -qtls -c tls.c
  Assembler:
  tls.s: line 76: Too few arguments
  1500-067: (S) asm statement generates errors in
     assembler output.
  
  
  The problem instruction generated in the *.s assembly file is:
  
     +76          addi      r0,0(r4)
  
  The parentheses syntax is invalid.  It should instead use a ','.
  

Local fix

• N/A
  

Problem summary

• PROBLEM DESCRIPTION:
  Assembly output from the compiler is using incorrect operand
  syntax.
  
  USERS AFFECTED:
  Those compiling source code that contains inline assembly and
  thread local storage, and are outputting to assembly code.
  

Problem conclusion

• An issue was corrected with the syntax type the compiler uses
  to output to assembly code.  The problem is now fixed.
  

Temporary fix
