Can all basic SIMD instructions

Hello,
I would like to bring to your notice this article about exposing SIMD
instructions to high level languages.

The Translation and JIT backend for PyPy may be able to allow Python
programmers to use SIMD instructions directly from Python.

Indeed. But fixing this is not too hard. Grep for "math_sqrt" and
"MATH_SQRT" in pypy/jit/*/*.py for an example of how we turn
sqrt_nonneg(x) into

There is a third solutio
Hi pypy list,
I'd like to prototype an interpreter in rpython. But this interpreter must
feature floating point support. Something like the context in the decimal
module of python : (decimal is basically a floating point unit in python)
import decimal
# do an operation
decimal.Decimal("6e4565465"
