- Subject: more SIMD operations
I am currently developing a background subtraction
program and I am looking at SIMD instructions to speed
it up. I would like to do this without the use of
assempler. I have therefore been looking at GCC's
support of such operations and found
http://gcc.gnu.org/onlinedocs/gcc/Vector-Extensions.html.
However GCC seems only to support +, -, *, /, and
unary minus. Are there any plans to support more
operators? I am especially thinking about saturated
versions of +, -, *, /, and absdiff.
