From 0ccdf23a57ed8f2a8763f4187b440720fa912937 Mon Sep 17 00:00:00 2001 From: Karol Herbst Date: Fri, 15 Mar 2019 16:06:22 +0100 Subject: [PATCH] nir/lower_locals_to_regs: cast array index to 32 bit local memory is too small to require 64 bit pointers, so cast the array index to a 32 bit value to save up on 64 bit operations.
