/* ROCR r_debug::r_version history:

1: Initial debug protocol
2: New trap handler ABI. The reason for halting a wave is recorded in
   ttmp11[8:7].
3: New trap handler ABI. A wave halted at S_ENDPGM rewinds its PC by 8 bytes,
   and sets ttmp11[9]=1.
4: New trap handler ABI. Save the trap id in ttmp11[17:10].
5: New trap handler ABI. Save the PC in ttmp11[22:7] ttmp6[31:0], and park the
   wave if stopped.
6: New trap handler ABI. ttmp6[25:0] contains dispatch index modulo queue size
7: New trap handler ABI. Send interrupts as a bitmask, coalescing concurrent
   exceptions.
8: New trap handler ABI. For gfx940: Initialize ttmp[4:5] if ttmp11[31] == 0.
9: New trap handler ABI. For gfx11: Save PC in ttmp11[22:7] ttmp6[31:0], and
   park the wave if stopped.
