Stephan Herhut authored
When assigning a register to a value that is used as a function argument, we use a hint to suggest the corresponding register. However, if the argument is also used after the call, the register will not be free for the entire live range of the value. Hence we need to split the live range. To minimize the number of splits, we aim to choose a register with maxium availability. This heuristic was implemented based on lifetime positions with sub-instruction precision. In such a model, argument registers typically have a shorter available time, as they need to hold a value before a call, whereas all other registers are free until right after the call, where they have been overwritten by the called function. Hence, we typically chose a non-argument register, ignoring the hint and creating an extra move. This change moves the heuristic to instruction granularity, which gives argument and other registers the same free time. We also now prefer hinted registers if they have the same free time.

In the WebAssembly fuzzers we detect infinite loops with the interpreter: if the interpreter does not finish after a finite number of steps, we do not execute the compiled code. However, we cannot redirect the start function to the interpreter in the fuzzer, and therefore we cannot detect infinite loops in the start function. With this CL we avoid the problem completely by not instantiating a module in the fuzzer which has a start function. Note that the module still gets compiled.
