Dynamic type checking in compiler design
WebMay 28, 2024 · @alephzero: Except that for external procedures in, say, UCSD Pascal, there were no runtime checks because no type information was available at runtime (at least in the UCSD p-Code variant I'm familiar with). So it's not a "compiler design compromise", and it doesn't "reduce the size of the compiler at the cost of the speed of the execution"; … WebIn this article, we propose a novel technique for quantifying compiler-internal events in the optimized code, reducing the profiling perturbation on compiler optimizations. Our technique achieves this by instrumenting the program from within the compiler, and by delaying the instrumentation until the point in the compilation pipeline after ...
