* [Darwin, specs] Tidy some more linker options.Iain Sandoe2019-06-191-7/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pie, no-pie and rdynamic are driver options, we can process them in the relevant place and drop them once dealt with. There's no need to generate a new header to process the "no_compact_unwind" which is applied on the basis of the target system. Support for the -pie, -no_pie and -no_compact_unwind options should ideally be checked at configure time, however the status quo is to assert that linkers capable of targeting the relevant systems support these options (i.e. we trust that the user doesn't attempt to configure inappropriately). TODO: check the availability of the linker opts in configure rather than trusting to the user. This will fix the fail of pie-7.c, which is a result of failing to handle the no-pie driver option. 2019-06-19 Iain Sandoe <iain@sandoe.co.uk> * config/darwin.h (DRIVER_SELF_SPECS): Add RDYNAMIC, DARWIN_PIE_SPEC and DARWIN_NOPIE_SPEC.

* [Darwin, config] Arrange for ld64 to be detected as Darwin's linker.Iain Sandoe2016-11-271-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <iain@codesourcery.com> 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.
