From 4b474e2e8a43bd53656754ea284db9c97e3bf948 Mon Sep 17 00:00:00 2001 From: Caio Marcelo de Oliveira Filho Date: Wed, 3 Apr 2019 12:45:22 -0700 Subject: [PATCH] spirv: Handle instruction aliases in spirv_info_c.py Choose the first we see in the grammar file as the main one. This is needed to parse SPIR-V 1.4 because it introduced opcode aliases.
