Build the pinned termtris branch (be5b323) with this compiler, assemble and link it with the TI 1987 GSPA/GSPLNK and RTS.LIB, and run the proven play_keys board/move/panels/quit paths in MAME with the M4 loader. Add the contiguous-stack varargs MAME probe and the switch-to-lookup driver regression check. The termtris build found the i8/i16 argument, i1/ anyext load, nested-data, MULHS and late-GEP gaps fixed in the compiler.

* switch.c -- a dense char switch, used by tests/m4/termtris.sh to pin the

* driver's late-GEP policy.
|

*
|
|
* The optimizer's switch-to-lookup-table transform creates a new i8 GEP after
|
|
* tms-bitaddr --scale; --normalize cannot tell that index apart from an
|
|
* already-scaled bit offset, so the table would be indexed one bit per slot.
|
|
* tms-clang passes -switch-to-lookup=false; this source makes the hazard
|
|
* reachable at -O2 (termtris' init_game and runesc switches are the real
|
|
* cases).
