From a0e887be6147edcd14a5b95af17456d0a01575d4 Mon Sep 17 00:00:00 2001 From: Iain Sandoe Date: Wed, 9 Oct 2019 18:43:36 +0000 Subject: [Darwin, machopic 3/n] Set a SYMBOL flag for indirections. We are able to treat these specially where needed in legitimate address tests (specifically, they are guaranteed to be pointer-aligned). gcc/ChangeLog: 2019-10-09 Iain Sandoe * config/darwin.c (machopic_indirect_data_reference): Set flag to indicate that the new symbol is an indirection. (machopic_indirect_call_target): Likewise. * config/darwin.h (MACHO_SYMBOL_FLAG_INDIRECTION): New. (MACHO_SYMBOL_INDIRECTION_P): New. (MACHO_SYMBOL_FLAG_STATIC): Adjust bit number.
