2015-11-15sim: d10v: drop global callback stateMike Frysinger1-1/+0
Now that we have access to the sim state in all the right places, use existing sim helpers in place of d10v_callback directly.
2015-11-15sim: d10v: convert to common sim engine logicMike Frysinger1-2/+0
Now that we have access to the sim state everywhere, we can convert to the common engine logic for overall processing. This frees us up from tracking exception state ourselves.
2015-11-15sim: d10v: push down sd/cpu varsMike Frysinger1-12/+12
By itself, this commit doesn't really change anything. It lays the groundwork for using the cpu state in follow up commits, both for engine state and for cpu state. Splitting things up this way so it is easier to see how things have changed.
2015-03-30sim: d10v: convert to nrunMike Frysinger1-4/+6
A lot of cpu state is stored in global variables, as is memory handling. The sim_size support needs unwinding at some point. But at least this is an improvement on the status quo.

From Jason Eckhardt <jle@redhat.com> * d10v_sim.h (INC_ADDR): Correctly handle the case where MOD_E is less than MOD_S (post-decrement).

through an exception may not work correctly. For GDB reads/writes to the control registers, ensure the cpu state is updated correctly.

* interp.c (sim_size): Now allocates unified memory for imap segments 0,1,2, and 127. Initializes imap0 and imap1 to 0x1000. Initializes dmap to 0. (sim_write): Just call xfer_mem(). (sim_read): Just call xfer_mem(). (xfer_mem): New function. Does appropriate memory mapping and copies bytes. (dmem_addr): New function. Reads dmap register and translates data addresses to local addresses. (pc_addr): New function. Reads imap register and computes local address corresponding to contents of the PC. (sim_resume): Change to use pc_addr(). (sim_create_inferior): Change reinitialization code. Also reinitializes imap[01] and dmap. (sim_fetch_register): Add fake registers 32,33,34 for imap0, imap1, and dmap. (sim_store_register): Add fake registers 32,33,34 for imap0, imap1, and dmap. * simops.c (MEMPTR): Redefine to use dmem_addr(). (OP_5F00): Replace references to STate.imem with dmem_addr(). * d10v-sim.h (State): Remove mem_min and mem_max. Add umem[128]. (RB,SW,RW,SLW,RLW): Redefine to use dmem_addr(). (IMAP0,IMAP1,DMAP,SET_IMAP,SET_IMAP1,SET_DMAP): Define.
