2015-10-28target-*: Advance pc after recognizing a breakpointRichard Henderson
Some targets already had this within their logic, but make sure it's present for all targets. Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Richard Henderson <rth@twiddle.net>
2015-10-07tcg: Remove gen_intermediate_code_pcRichard Henderson
It is no longer used, so tidy up everything reached by it. This includes the gen_opc_* arrays, the search_pc parameter and the inline gen_intermediate_code_internal functions.

2015-10-07tcg: Pass data argument to restore_state_to_opcRichard Henderson
The gen_opc_* arrays are already redundant with the data stored in the insn_start arguments. Transition restore_state_to_opc to use data from the latter.

2015-10-07target-*: Introduce and use cpu_breakpoint_testRichard Henderson
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.

2015-10-07target-*: Unconditionally emit tcg_gen_insn_startRichard Henderson
While we're at it, emit the opcode adjacent to where we currently record data for search_pc. This puts gen_io_start et al on the "correct" side of the marker.

2015-09-11tlb: Add "ifetch" argument to cpu_mmu_index()Benjamin Herrenschmidt
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.

2015-09-11maint: remove / fix many doubled wordsDaniel P. Berrange
Many source files have doubled words (eg "the the", "to to", and so on). Most of these can simply be removed, but a couple were actual mis-spellings (eg "to to" instead of "to do").

2015-06-22disas: Remove uses of CPU envPeter Crosthwaite
disas does not need to access the CPU env for any reason. Change the APIs to accept CPU pointers instead. Small change pattern needs to be applied to all target translate.c. This brings us closer to making disas.o a common-obj and less architecture specific in general. Cc: Richard Henderson <rth@twiddle.net> Cc: Peter Maydell <peter.maydell@linaro.org> Cc: "Edgar E.

2015-03-13tcg: Change translator-side labels to a pointerRichard Henderson
This is improved type checking for the translators -- it's no longer possible to accidentally swap arguments to the branch functions. Note that the code generating backends still manipulate labels as int. With notable exceptions, the scope of the change is just a few lines for each target, so it's not worth building extra machinery to do this change in per-target increments.

Remove the function qemu_log_try_set_file() and its users (which are all in TCG code generation functions for various targets). This function was added to abstract out code which was originally written as "if (!logfile) logfile = stderr;" in order that BUG: case code which did an unguarded "fprintf(logfile, ...)" would not crash if debug logging was not enabled. Since those direct uses of logfile have also been abstracted away into qemu_log() calls which check for a NULL logfile, there is no need for the target-* files to mess with the user's chosen logging settings.
