From 87b0cab8d8701db7754e5778b93ff83ffc64c7ae Mon Sep 17 00:00:00 2001 From: Sultan Alsawaf Date: Sun, 8 Mar 2020 00:31:35 -0800 Subject: ZEN: Disable stack conservation for GCC There's plenty of room on the stack for a few more inlined bytes here and there. The measured stack usage at runtime is still safe without this, and performance is surely improved at a microscopic level, so remove it.
