Even if CONST_OR_PURE_CALL_P is set to 1??? :-(I don't know, but in any case __tls_get_addr is neither pure nor const
rs6000 says it is, I should try doing the same for x86-64 and see what happens.
(and for non-TLS libcalls, we don't have to know because we never make them dead anyway ;-).
Well, for optab libcalls we know:
value = emit_library_call_value (binoptab->handlers[(int) mode].libfunc,
NULL_RTX, LCT_CONST, mode, 2,
op0, mode, op1x, op1_mode);
