2019-02-24Optimize address translation and write tracking on the MMU (#571)gdkchan
* Implement faster address translation and write tracking on the MMU * Rename MemoryAlloc to MemoryManagement, and other nits * Support multi-level page tables * Fix typo * Reword comment a bit * Support scalar vector loads/stores on the memory fast path, and minor fixes * Add missing cast * Alignment * Fix VirtualFree function signature * Change MemoryProtection enum to uint aswell for consistency
2019-01-29Implement some ARM32 memory instructions and CMP (#565)gdkchan
* Implement ARM32 memory instructions: LDM, LDR, LDRB, LDRD, LDRH, LDRSB, LDRSH, STM, STR, STRB, STRD, STRH (immediate and register + immediate variants), implement CMP (immediate and register shifted by immediate variants) * Rename some opcode classes and flag masks for consistency * Fix a few suboptimal ARM32 codegen issues, only loads should be considered on decoder when checking if Rt == PC, and only NZCV flags should be considered for comparison optimizations * Take into account Rt2 for LDRD instructions aswell when checking if the instruction changes PC * Re-align arm32 instructions on the opcode table
