Writing AVX2 intrinsics manually takes hours. This agent does it in seconds.
Writing even a simple horizontal sum in AVX2 requires knowing which intrinsics exist, how lane isolation breaks naive implementations, and how to compose 4 to 5 operations in the right order. This is the Intel Intrinsics Guide — six thousand entries. Every SIMD operation you write, you're doing this manually.
Let's start simple — element-wise multiply. The agent parses the intent, synthesizes AVX2 code, compiles it, val
