2021-03-13target/mips/tx79: Move MFHI1 / MFLO1 opcodes to decodetreePhilippe Mathieu-Daudé
Introduce decodetree structure to decode the tx79 opcodes. Start it by moving the existing MFHI1 and MFLO1 opcodes. Remove unnecessary comments. As the TX79 share opcodes with the TX19/TX39/TX49 CPUs, we introduce the decode_ext_txx9() dispatcher where we will add the other decoders later.

Introduce the 'msa32' decodetree config for the 32-bit MSA ASE. We start by decoding: - the branch instructions, - all instructions based on the MSA opcode.

2021-01-14target/mips: Extract MSA translation routinesPhilippe Mathieu-Daudé
Extract 2200 lines from the huge translate.c to a new file, 'msa_translate.c'. As there are too many inter-dependencies we don't compile it as another object yet, but keep including it in the big translate.o. We gain in code maintainability.

2020-12-13hw/mips: Move address translation helpers to target/mips/Philippe Mathieu-Daudé
Address translation is an architectural thing (not hardware related). Move the helpers from hw/ to target/. As physical address and KVM are specific to system mode emulation, restrict this file to softmmu, so it doesn't get compiled for user-mode emulation.

Similar to hw_arch, each architecture defines two sourceset which are placed in dictionaries target_arch and target_softmmu_arch. These are then picked up from there when building the per-emulator static_library. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
