Once you get used to working with gofmt on a daily basis, you want to have it everywhere. I have been writing a good amount of assembler for Go, and I was getting annoyed by not having similar functionality for assembler.
Update 2015: This is a re-post of a 2010 article I wrote for the Rawstudio blog, which at the time of writing is off-line.
I have written a Discussion Piece about how it could be possible to implement assembler intrinsics in Go based on an experiment I have been working on the past week. The goal of the experiment was to see if intrinsics are feasible within the Go language without breaking the language. It is my impression that…
I have worked on optimizing the standard library deflate function, and I am happy to announce revised gzip/zip packages, that on x64 is about 30-50% faster with slightly improved compression.
For an experimental project, I wanted to use an SSE 4.1 instruction (MPSADBW) for some Go assembler. I found out that this instruction wasn’t supported by the Go assembler in the current 1.4.2 version. The proposed solution is to add this as raw opcodes in the assembler. The instruction (in Go assembler syntax) is: MPSADBW…
