  • 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
