2012-11-10disas: avoid using cpu_single_envBlue Swirl

2012-09-27Emit debug_insn for CPU_LOG_TB_OP_OPT as well.Richard Henderson
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.

2011-10-08target-alpha: Add high-resolution access to wall clock and an alarm.Richard Henderson
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.

2011-05-31target-alpha: Implement TLB flush primitives.Richard Henderson
Expose these via MTPR, more or less like the real HW does. Signed-off-by: Richard Henderson <rth@twiddle.net>
2011-05-31target-alpha: Implement more CALL_PAL values inline.Richard Henderson
In particular, SWPIPL is used quite a lot by the Linux kernel. Doing this inline makes it significantly easier to step through without the debugger getting confused by the mode switch. Signed-off-by: Richard Henderson <rth@twiddle.net>
2011-05-31target-alpha: All ISA checks to use TB->FLAGS.Richard Henderson
We had two different methods in use, both of which referenced ENV, and neither of which indicated to the generic code when different compilation modes are not compatible. Signed-off-by: Richard Henderson <rth@twiddle.net>
2011-05-31target-alpha: Add IPRs to be used by the emulation PALcode.Richard Henderson
These aren't actually used yet, but we can at least access them via the HW_MFPR and HW_MTPR instructions. Signed-off-by: Richard Henderson <rth@twiddle.net>

2011-05-31target-alpha: Add various symbolic constants.Richard Henderson
The EXC_M_* constants were being set for the EV6, not as set for the Unix kernel entry point. Use PS_USER_MODE instead of hard-coding access to the PS register. Signed-off-by: Richard Henderson <rth@twiddle.net>
2011-05-31target-alpha: Tidy exception constants.Richard Henderson
There's no need to attempt to match EXCP_* values with PALcode entry point offsets. Instead, compress all the values to make for more efficient switch statements within QEMU. We will be doing TLB fill within QEMU proper, not within the PALcode, so all of the ITB/DTB miss, double fault, and access exceptions can be compressed to EXCP_MMFAULT. Compress all of the EXCP_CALL_PAL exceptions into one. Use env->error_code to store the specific entry point. Signed-off-by: Richard Henderson <rth@twiddle.net>
2011-05-31target-alpha: Rationalize internal processor registers.Richard Henderson
Delete all the code that tried to emulate the real IPRs of some unnamed CPU. Replace those with just 3 slots that we can use to communicate trap information between the helper functions that signal exceptions and the OS trap handler. Signed-off-by: Richard Henderson <rth@twiddle.net>

2011-05-31target-alpha: Fix system store_conditionalRichard Henderson
This code contained typos, as it had never been compiled. Signed-off-by: Richard Henderson <rth@twiddle.net>
2011-05-31target-alpha: Fix translation of PALmode memory insns.Richard Henderson
All of the "raw" memory accesses should be "phys" instead. Fix some confusion about argument ordering of the store routines. Fix the implementation of store-conditional. Delete the "alt-mode" helpers. Because we only implement two mmu modes, let /a imply user-mode unconditionally. Leave some combinations of virt access without permission checks as unimplemented. There are too many hoops through which to jump, and these insns will not be needed in the emulation palcode. Signed-off-by: Richard Henderson <rth@twiddle.net>
2011-05-31target-alpha: Remove partial support for palcode emulation.Richard Henderson
This code does not work, and will be replaced by a bios image. Signed-off-by: Richard Henderson <rth@twiddle.net>
2011-05-31target-alpha: Single-step properly across branches.Richard Henderson
We were failing to generate EXC_DEBUG in the EXIT_PC_UPDATED path. This caused us not to stop at the instruction after a branch, but on the instruction afterward. Signed-off-by: Richard Henderson <rth@twiddle.net>
2011-04-20Remove unused function parameters from gen_pc_load and rename the functionStefan Weil
Function gen_pc_load was introduced in commit d2856f1ad4c259e5766847c49acbb4e390731bd4. The only reason for parameter searched_pc was a debug statement in target-i386/translate.c. Parameter puc was needed by target-sparc until commit d7da2a10402f1644128b66414ca8f86bdea9ae7c. Remove searched_pc from the debug statement and remove both parameters from the parameter list of gen_pc_load. As the function name gen_pc_load was also misleading, it is now called restore_state_to_opc. This new name was suggested by Peter Maydell, thanks. v2: Remove last parameter, too, and rename the function. v3: Fix [] typo in target-arm/translate.c. Fix wrong SHA1 object name in commit message (copy+paste error).

2011-04-10Fix conversions from pointer to tcg_target_longStefan Weil
tcg_gen_exit_tb takes a parameter of type tcg_target_long, so the type casts of pointer to long should be replaced by type casts of pointer to tcg_target_long (suggested by Blue Swirl). These changes are needed for build environments where sizeof(long) != sizeof(void *), especially for w64.
