From a7c70129b9cb1cc9300400dc4f4adc639f0ba9c3 Mon Sep 17 00:00:00 2001 From: Iain Sandoe Date: Fri, 13 Dec 2019 21:06:22 +0000 Subject: [PATCH] [Darwin, PPC] Use Darwin9 dylib header for Rosetta builds. On Darwin10 it's possible to make a 32b PPC build using the 'Rosetta' emulator. However, these builds need to make use of Darwin9 crts (for exes and dylibs). This adds the change to cater for dylibs. gcc/ChangeLog: 2019-12-13 Iain Sandoe * config/rs6000/darwin.h (DARWIN_DYLIB1_SPEC): New.
