2014-12-16disas/mips: disable unused mips16_to_32_reg_map[]Leon Alrae1-1/+2
This array is used by print_mips16_insn_arg() which is guarded by #if 0. Therefore doing the same with the array as it generates clang warnings. Signed-off-by: Leon Alrae <leon.alrae@imgtec.com>

2014-11-03target-mips: add TLBINV supportLeon Alrae1-0/+2
For Standard TLB configuration (Config.MT=1): TLBINV invalidates a set of TLB entries based on ASID. The virtual address is ignored in the entry match. TLB entries which have their G bit set to 1 are not modified. TLBINVF causes all entries to be invalidated. Single TLB entry can be marked as invalid on TLB entry write by having EntryHi.EHINV set to 1. Signed-off-by: Leon Alrae <leon.alrae@imgtec.com> Reviewed-by: Yongbok Kim <yongbok.kim@imgtec.com>

2014-10-14target-mips: add new Floating Point instructionsLeon Alrae1-0/+22
In terms of encoding MIPS32R6 MIN.fmt, MAX.fmt, MINA.fmt, MAXA.fmt replaced MIPS-3D RECIP1, RECIP2, RSQRT1, RSQRT2 instructions. In R6 all Floating Point instructions are supposed to be IEEE-2008 compliant i.e. FIR.HAS2008 always 1. However, QEMU softfloat for MIPS has not been updated yet.

2014-10-13target-mips: add compact and CP1 branchesYongbok Kim1-3/+64
Introduce MIPS32R6 Compact Branch instructions which do not have delay slot - they have forbidden slot instead. However, current implementation does not support forbidden slot yet. Add also BC1EQZ and BC1NEZ instructions. Signed-off-by: Yongbok Kim <yongbok.kim@imgtec.com> Signed-off-by: Leon Alrae <leon.alrae@imgtec.com>

2014-10-13target-mips: move CLO, DCLO, CLZ, DCLZ, SDBBP and free special2 in R6Leon Alrae1-0/+5
Also consider OPC_SPIM instruction as deleted in R6 because it is overlaping with MIPS32R6 SDBBP. Signed-off-by: Leon Alrae <leon.alrae@imgtec.com> Reviewed-by: Aurelien Jarno <aurelien@aurel32.net>
2014-10-13target-mips: redefine Integer Multiply and Divide instructionsLeon Alrae1-0/+16

2014-10-13target-mips: move PREF, CACHE, LLD and SCD instructionsLeon Alrae1-0/+4
The encoding of PREF, CACHE, LLD and SCD instruction changed in MIPS32R6. Additionally, the hint codes in PREF instruction greater than or equal to 24 generate Reserved Instruction Exception. Signed-off-by: Leon Alrae <leon.alrae@imgtec.com> Reviewed-by: Aurelien Jarno <aurelien@aurel32.net>
