From 6afab66ea6311211e0e82963e372daf7a7e86da8 Mon Sep 17 00:00:00 2001 From: iains Date: Sun, 27 Nov 2016 14:29:36 +0000 Subject: [Darwin, config] Arrange for ld64 to be detected as Darwin's linker. This is an initial patch in a series that converts Darwin's configury to detect ld64 features, rather than the current process of hard-coding them on target system version. A ld64-compatible linker is currently required and assumed by Darwin. If a DEFAULT_LINKER is set via --with-ld= then this will be tested to see if it is ld64. The ld64 version is determined for the chosen ld and this is exported for use in setting a default value for -mtarget-linker (needed for run-time code-gen changes to section choices). The support for -rdynamic is converted to be detected at config time, or by the ld64 version if that is found. gcc/ 2016-11-27 Iain Sandoe PR target/71767 * configure.ac (with-ld64): New var, set for Darwin, set on detection of ld64, gcc_cv_ld64_export_dynamic: New, New test. * config/darwin.h: Use LD64_HAS_DYNAMIC export.
