* Emit debug_insn for CPU_LOG_TB_OP_OPT as well.Richard Henderson2012-09-271-1/+1
| | | | | | | | | | | For all targets that currently call tcg_gen_debug_insn_start, add CPU_LOG_TB_OP_OPT to the condition that gates it. This is useful for comparing optimization dumps, when the pre-optimization dump is merely noise.

* target-alpha: Add high-resolution access to wall clock and an alarm.Richard Henderson2011-10-084-4/+48
| | | | | | | | | | | | | The alarm is a fully general one-shot time comparator, which will be usable under Linux as a hrtimer source. It's much more flexible than the RTC source available on real hardware. The wall clock allows the guest access to the host timekeeping. Much like the KVM wall clock source for other guests. Both are accessed via the PALcode Cserve entry point. Signed-off-by: Richard Henderson <rth@twiddle.net>

Move also various other stuff only used in op_helper.c there. Define global env in dyngen-exec.h. For i386, move wrappers for segment and FPU helpers from user-exec.c to op_helper.c. Implement raise_exception_err_env() to handle dynamic CPUState. Move the function declarations to cpu.h since they can be used outside of op_helper.c context. LM32, s390x, UniCore32: remove unused cpu_halted(), regs_to_env() and env_to_regs(). ARM: make raise_exception() static.
