Description
To report a new bug, please open a separate issue.
x86/x86_64
_mm_shuffle_psmasks argument type is anu32instead of ani32(like for all other shuffle intrinsics), this is a bug in the Intel Intrinsics Guide, reported in #522_rdtscreturns a signed integer type instead of an unsigned one, this is a bug in the Intel Intrinsics Guide (https://software.intel.com/en-us/forums/intel-isa-extensions/topic/363747), reported in #559_mm_pausedoes not require SSE2, but we initially did because the intel intrinsics guide says it is required. This is a bug in the Intel Intrinsics Guide: not reported yet. See #705

Research direction
Start by reviewing the listed x86/x86_64 discrepancies against the Intel Intrinsics Guide and the referenced issues #522, #559, and #705. Confirm the expected argument and return types and the SSE2 requirement, then verify each discrepancy in the stable intrinsics APIs and their tests before considering the list resolved.
