| | | | | You may know that all numbers in JavaScript are 64 bit double-precision floating point values. This is sometimes convenient and it works pretty well as a default for novice programmers, who are often confused by integer math, and rightfully so when 1 / 2 = 0. Unfortunately, it makes things slow. Doubles take a lot of memory and floating point math is slower than integer math on CPUs. It's also inconvenient if you want to port existing code to JavaScript, because existing code usually expects to use integ... | |

| | | | | Here is a rough approximation of float multiplication (source): float rough_float_multiply(float a, float b) { constexpr uint32_t bias = 0x3f76d000; return bit_cast(bit_cast(a) + bit_cast(b) - bias); } We're casting the floats to ints, adding them, adjusting the exponent, and returning as float. If you think about it for a second you will realize that since... | |

| | | [AI summary] The article discusses the development of an Ahead-of-Time (AOT) compiler for JavaScript, leveraging precompiled inline-cache (IC) stubs. By moving runtime type binding to indirect calls, the compiler can generate static code, enabling full AOT compilation. This approach achieves significant performance improvements, with a 2.77x geometric mean speedup on various benchmarks. The article also explores further optimizations through profile-guided inlining, and compares this method with other AOT approaches like Hopc's type inference. The potential for future enhancements and the use of compiler backends derived from interpreters are also highlighted. | ||
