Overview

comment from dr_defines.h:

The SSE registers xmm0-xmm5 (-xmm15 on Linux) are volatile (caller-saved) for 64-bit and WOW64, and are actually zeroed out on Windows system calls. These fields are ignored for 32-bit processes that are not WOW64, or if the underlying processor does not support SSE. Use dr_mcontext_xmm_fields_valid() to determine whether the fields are valid.
