Fundamental flaws of SIMD ISAs (2021)
According to Flynn’s taxonomy SIMD refers to a computer architecture that can process multiple data streams with a single instruction (i.e. “Single Instruction stream, Multiple Data streams”). There are different taxonomies, and within those several different sub-categories and architectures that classify as “SIMD”.

What the hell is a target triple?
Cross-compiling is taking a computer program and compiling it for a machine that isn’t the one hosting the compilation. Although historically compilers would only compile for the host machine, this is considered an anachronism: all serious native compilers are now cross-compilers.

Fun with -fsanitize=undefined and Picolibc
Both GCC and Clang support the -fsanitize=undefined flag which instruments the generated code to detect places where the program wanders into parts of the C language specification which are either undefined or implementation defined. Many of these are also common programming errors. It would be great if there were…

My Own Private Binary: An Idiosyncratic Introduction to Linux Kernel Modules
Several years ago, I spent a serious chunk of time figuring out how to make really teensy ELF executable files. I started down this path because I was annoyed that all of my programs, no matter how short they were, never got smaller than 4k or so. I felt that was excessive, for C, and so I started looking at what ELF…
