+/* If TLS is in use, we have a conflict between the PAL_rduniq primitive,
+   as modeled within GCC, and explicit use of the R0 register.  If we use
+   the register via the asm, the scheduler may place the PAL_rduniq insn
+   before we've copied the data from R0 into _sc_ret.  If this happens 
+   we'll get a reload abort, since R0 is live at the same time it is 
+   needed for the PAL_rduniq.
+
+   Solve this by using the "v" constraint instead of an asm for the syscall
+   output.  We don't do this unconditionally to allow compilation with
+   older compilers.  */
