2018-05-09translator: merge max_insns into DisasContextBaseEmilio G. Cota1-5/+2
While at it, use int for both num_insns and max_insns to make sure we have same-type comparisons.

Drop TCGV_PTR_TO_NAT and TCGV_NAT_TO_PTR internal macros. Add tcg_temp_local_new_ptr, tcg_gen_brcondi_ptr, tcg_gen_ext_i32_ptr, tcg_gen_trunc_i64_ptr, tcg_gen_extu_ptr_i64, tcg_gen_trunc_ptr_i32.

2018-03-26target/hppa: Include priv level in user-only iaoqRichard Henderson2-10/+6
A recent glibc change relies on the fact that the iaoq must be 3, and computes an address based on that. QEMU had been ignoring the priv level for user-only, which produced an incorrect address.

2018-02-21target/*/cpu.h: remove softfloat.hAlex Bennée3-2/+2
As cpu.h is another typically widely included file which doesn't need full access to the softfloat API we can remove the includes from here as well. Where they do need types it's typically for float_status and the rounding modes so we move that to softfloat-types.h as well. As a result of not having softfloat in every cpu.h call we now need to add it to various helpers that do need the full softfloat.h definitions.

2018-01-25accel/tcg: add size paremeter in tlb_fill()Laurent Vivier3-3/+4
The MC68040 MMU provides the size of the access that triggers the page fault. This size is set in the Special Status Word which is written in the stack frame of the access fault exception. So we need the size in m68k_cpu_unassigned_access() and m68k_cpu_handle_mmu_fault(). To be able to do that, this patch modifies the prototype of handle_mmu_fault handler, tlb_fill() and probe_write(). do_unassigned_access() already includes a size parameter. This patch also updates handle_mmu_fault handlers and tlb_fill() of all targets (only parameter, no code change).
