Pettenò: Debunking x32 myths

Earlier this month LWN covered the announcement of an initial x32 release candidate of Gentoo. The x32 ABI enables the running of processes in 64-bit mode while using 32-bit pointers. Gentoo developer Diego Elio "Flameeyes" Pettenò isn't convinced that x32 is the way to go, and debunks some common misconceptions about the x32 ABI. "The new x32 ABI has proven to be faster. Not really; what we have right now are a few benchmarks, published by those who actually created the ABI, Of course you’d expect that those who spent time to set it up found it interesting and actually faster, but I honestly have doubts about the results, for reasons that will be clearer by reading the next few entries."
