The new test rck_e.e segfaults on PowerPC unless I make some changes. The inline code for _rck_ was wrong because it didn't allow the trap handler to return. _sig_ forgot to push the old trap handler. Move plat/linuxppc/libsys/trap.s to mach/powerpc/libem/trp.s and rewrite it with simplified/extended mnemonics. Remove .trap alias for .trp procedure. Add a missing `mtspr lr, r0` so we can return from the trap handler. Call write() and _exit() so trp.s works with both linuxppc and osxppc. Before, Mac OS X was wrongly using the trap.s for Linux. In powerpc/libem, simplify .aar4; teach .csa and .csb to raise the trap if the default target is zero. C programs don't need these changes. You may relink your C programs with the changed .csa and .csb, but C code doesn't raise the trap. Modula-2 code can raise traps, so you may want to relink your Modula-2 programs with the changed libem, but you might keep your old .o files from Modula-2. You may need to recompile your Pascal programs (delete old .o files from Pascal) because the Pascal compiler might use _rck_.
