![]() * Added new opcode LZCNT which returns the number of leading zeros in a parameter. * Added new opcode XTRACT which is a combined rotate/mask (basically rlwinm from PowerPC) * Added new opcode INSERT which is a combined rotate/mask/blend (basically rlwimi from PowerPC). Best. Opcode. Ever. * Updated all back-ends to support these new opcodes. * Fixed several bugs relating to shifts/rotates and optimizing out cases incorrectly. MIPS3 DRC changes: * Updated to use INSERT and XTRACT where appropriate * Cleaned up register usage to enable an additional direct mapping; this means Linux gets 1 now and Windows gets 3 |
