* target-cris: Mirror gen_opc_pc into insn_startRichard Henderson2015-10-071-1/+2
| | | | | | | | | | | | | This perhaps isn't ideal in terms of (ab)using the "pc" field to encode both pc and ppc + delay branch state, as one has to be aware of this when examining opcode dumps. But it preserves existing logic, which will be good for bisection, and it certainly does save storage space.

| | | | | | | | | | | | Reduce the boilerplate required for each target. At the same time, move the test for breakpoint after calling tcg_gen_insn_start. Note that arm and aarch64 do not use cpu_breakpoint_test, but still move the inline test down after tcg_gen_insn_start.

The bootloader can just pass EM_CRIS directly, as that is architecture specific code. This removes another architecture specific definition from the global namespace. Cc: Edgar E.

* tlb: Add "ifetch" argument to cpu_mmu_index()Benjamin Herrenschmidt2015-09-113-5/+5
| | | | | | | | | | | | | | | | | | This is set to true when the index is for an instruction fetch translation. The core get_page_addr_code() sets it, as do the SOFTMMU_CODE_ACCESS acessors. All targets ignore it for now, and all other callers pass "false". This will allow targets who wish to split the mmu index between instruction and data accesses to do so. A subsequent patch will do just that for PowerPC.

Note that the code generating backends still manipulate labels as int.

* gdbstub: Allow target CPUs to specify watchpoint STOP_BEFORE_ACCESS flagPeter Maydell2014-10-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | GDB assumes that watchpoint set via the gdbstub remote protocol will behave in the same way as hardware watchpoints for the target. In particular, whether the CPU stops with the PC before or after the insn which triggers the watchpoint is target dependent. Allow guest CPU code to specify which behaviour to use. This fixes a bug where with guest CPUs which stop before the accessing insn GDB would manually step forward over what it thought was the insn and end up one insn further forward than it should be. We set this flag for the CPU architectures which set gdbarch_have_nonsteppable_watchpoint in gdb 7.7: ARM, CRIS, LM32, MIPS and Xtensa.
