Embecosm is the company blog at embecosm.com, writing about programming and systems. Since 2015, 16 different Hacker News readers have linked it 19 times, most often “GCC-Rust Development Plan”. It is still writing: the last post was on 2026-10-20, and you can follow it by feed.
Too few sampled comments (9) to say how often HN recommends it.?
Why HN links it
HN readers link Embecosm's posts on compiler and toolchain work, including GCC, LLVM, Rust front ends, and RISC-V and Arm extensions. Comments mostly cite them as sources for technical points.
Summarised by Claude from a sample of 9 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

HN discussionWho do you think does most of the work in LLVM for example? It is full of PhD paper contributions. For example, research students doing internships at Embecosm ( https://embecosm.com ), as many others, plenty of material from LLVM Developers Meeting sessions.

HN discussionOne example is the guys from Embecosm, http://www.embecosm.com/ Not everything they do comes back to LLVM, it depends on the customer willingness to let it happen.

HN discussionMost of the embedded world has 8-bit bytes, not just ARM. Even when it comes to XAP2, there's the newer XAP2b which apparently supports byte addressing [1]. But if you do want larger bytes… well, the first step would be getting LLVM to support them. According to this blog post from last year, it's theoretically possible but would need work: https://www.embecosm.com/2017/04/18/non-8-bit-char-support-i... And of cours…

HN discussionAgreed on the sentiment. There is zero chance of getting it into the base, C or even M sets, as they have existing implementations. But maybe a lone Z (without the usual lowercase letters) could mean just this instruction. I found this to be a helpful discussion: https://www.embecosm.com/2019/10/22/gcc-risc-v-bit-manipulat...

HN discussionTo be fair, the octet as the byte has been dominant for decades. POSIX even has the definition “A byte is composed of a contiguous sequence of 8 bits.” I would wager many software engineers don't even know that a non-octet bytes were a thing, given that college CS curricula typically just teach a byte is 8 bits. I found some search results about Texas Instruments' digital signal processors using 16-bit bytes, and ca…
