[Qemu-devel] [PATCH v2 3/6] target/mips: Fix HI[ac] and LO[ac] 32-bit truncation with MIPS64 DSP ASE

2018-11-07 Thread Fredrik Noring
This change removes the 32-bit truncation of the HI[ac] and LO[ac] special purpose registers when ac range from 1 to 3 for the instructions MFHI, MFLO, MTHI and MTLO. The "MIPS Architecture for Programmers Volume IV-e: MIPS DSP Module for MIPS64 Architecture" manual specifies that all 64 bits are c
