From 534a7a7eedade86800c4cb6f8d0c347f500ec82c Mon Sep 17 00:00:00 2001 From: Jordan Rose Date: Fri, 11 Nov 2016 00:55:14 +0000 Subject: [PATCH] Speculative fix for va_list/nullability test on Hexagon and PPC. PowerPC's va_list, at least, is a typedef for an array, which means it decays to a pointer in parameter position. Since the decayed type is built from the array element type, the typedef sugar is lost.
