2019-01-24target/mips: Correct the second argument type of cpu_supports_isa()Aleksandar Markovic2-2/+2
"insn_flags" bitfield was expanded from 32-bit to 64-bit in commit f9c9cd63e3. However, this was not reflected on the second argument of the function cpu_supports_isa(). By chance, this did not create some wrong behavior, since the left-most halves of all instances of the second argument are currently all zeros. However, this is still a bug waiting to happen. Correct this by changing the type of the second argument to be always 64-bit. Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Signed-off-by: Aleksandar Markovic <amarkovic@wavecomp.com>

2019-01-03target/mips: MXU: Add handlers for logic instructionsAleksandar Markovic1-34/+205
Add translation handlers for four logic MXU instructions. It should be noted that there is an error in MXU documentation (dated June 2017) regarding opcodes for this group of instructions. This was confirmed by running tests on hardware, and also by looking up other related public source trees (binutils, Android NDK). In initial MXU patches to QEMU, opcodes for MXU logic instructions were created to be in accordance with the MXU documentation, therefore the error from was propagated. This patch corrects that, changing the involved code. Besides that, as MXU was designed and implemented only for 32-bit CPUs, corresponding preprosessor conditions were added around MXU code, which allows more flexible implementation of MXU handlers.
