Cc: Richard Henderson <rth@twiddle.net> Reviewed-by: Richard Henderson <rth@twiddle.net> Acked-By: Riku Voipio <riku.voipio@linaro.org> Signed-off-by: Peter Crosthwaite <crosthwaite.peter@gmail.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> * tlb: Add "ifetch" argument to cpu_mmu_index()Benjamin Herrenschmidt2015-09-111-1/+1 | | | | | | | | | | | | | | | | | | 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.

We simply encode the shadow registers into the translation. The VMStateDescription version changes, because the meaning of "shadow" changes in the save file when in PALmode. It would be possible to fix this, but I don't think it's worth the effort.

However, all our guest CPUs have that support (the only two which do not define TARGET_HAS_ICE are unicore32 and openrisc, and in both those cases the bp support is present and the lack of the #define is just a bug). So remove the #define entirely: all new guest CPU support should include breakpoint handling as part of the basic implementation.
