2009-11-10 | X86: Fix bugs in movd implementation. | Vince Weaver | |
Unfortunately my implementation of the movd instruction had two bugs. In one case, when moving a 32-bit value into an xmm register, the lower half of the xmm register was not zero extended. The other case is that xmm was used instead of xmmlm as the source for a register move. My test case didn't notice this at first as it moved xmm0 to eax, which both have the same register number. | |||
2009-10-30 | X86: Implement movd_Vo_Edp on X86 | Vince Weaver | |
This patch implements the movd_Vo_Edp series of instructions. It addresses various concerns by Gabe Black about which file the instruction belonged in, as well as supporting REX prefixed instructions properly. This instruction is needed for some of the spec2k benchmarks, most notably bzip2. | |||
2009-08-17 | X86: Implement MOVNTI. | Gabe Black | |
2009-08-08 | X86: Make not taken conditional moves leave the destination alone. Adjust ↵ | Gabe Black | |
CMOVcc. The manuals from both AMD and Intel say that when writing to a 32 bit destination in 64 bit mode, the upper 32 bits of the register are filled with zeros. They also both say that the CMOV instructions leave their destination alone when their condition fails. Unfortunately, it seems that CMOV will zero extend its destination register whether or not it was supposed to actually do a move on both platforms. This seems to be the only case where this happens, but it would be hard to say for sure. | |||

2009-02-25 | X86: Fix a few bugs with the segment register instructions in real mode. | Gabe Black | |
Fix a few instances where the register form of zext was used where zexti was intended. Also get rid of the 64 bit only rip relative addressed version since 64 bit and real mode are mutually exclusive. | |||
