Hello all, Assume GCC16 (or future GCC17) targetting a common Von Neumann 64 bits architecture (eg RISCV, AMD64, ARM-Aarch64, POWERPC-64).
Are there cases where the pointed type changes the generated code. To be more concrete, I am thinking of generated C99 or C17 code (not human written one). If every generated pointer was void* and at every dereferencing occurrence explicitly casted to the actual data pointer, does that make any difference in generated assembler code? In other words, is declaring only void* fields and local variables and casting them on every dereferencing use makes a difference in generated code. My guess is no, but I could be wrong.
