--- Comment #1 from Alan Modra <amodra at gmail dot com> ---
These are the insns that currently use the L field (or an alias).

 {"cmpli",   {BF, L, RA, UISIGNOPT}},
 {"cmpi",    {BF, L, RA, SI}},
 {"cmp",     {BF, L, RA, RB}},
 {"cmpl",    {BF, L, RA, RB}},
 {"dcbf",    {RA0, RB, L}},
 {"mtsle",   {L}},
 {"cmprb",   {BF, L, RA, RB}},
 {"tlbiel",  {RB, L}},
 {"tlbie",   {RB, L}},
 {"tbegin.", {HTM_R}},
 {"tsr.",    {L}},
 {"wclrall", {L}},
 {"wclr",    {L, RA0, RB}},

I'm inclined to say L should be optional when generating ppc32 code, for cmp*
and tlbie.  Not optional everywhere else.  What do you think?
