2007-07-26X86: Add functions to read and write to an exec context.Gabe Black
These functions take care of calling the thread contexts read and write functions with the right sized data type, and handle unaligned accesses. --HG-- extra : convert_revision : b4b59ab2b22559333035185946bae3eab316c879
2007-07-26X86: Fix carry calculation for subtraction based microops.Gabe Black
The carry flag should be calculated using the -complement- of the second operand, not it's negation. The carry in which is part of computing the 2's complement may induce a carry, but if you've already caused the carry before you get the carry computing logic involved, it will miss it. --HG-- extra : convert_revision : 318cf86929664fc52ed9e023606a9e892eba635c
