Disabling SSE2 support  Disabling SSE2 support   Hi folks. I
found SDE to be fantastic for emulating instruction sets not
supported by my CPU, but is it possible to do the reverse and
disable support for specific extensions?  I'm working on a
project that uses lots of assembly intrinsics in an abstract
vector math library. But things like vectors of 4 integers are
only supported when the CPU has SSE2 capabilities, and some
operations even require SSE3 or SSE4. It's up to the user to
know when an operation can be used or not, and this is becoming
very hard to test rigorously since I don't have a system without
SSE2 support at my disposal.  If SDE is of no help in this
situation, does anyone perhaps know of other ways to disable
specific instruction set extensions on the CPU? Thanks for any
suggestions.  7 帖子 / 0 new Mark Charney (Intel)的头像  Hi, Thanks
for the feedback. Yes, you can use the "-chip-check PENTIUM3" to
catch the execution of SSE2 instructions (and other instructions
added on Pentium4). Look at the
