Hi,

The darwinN.h headers were (presumably) introduced to allow specs to be
adjusted when there was no mmacosx-version-min handling, or that was
considered unreliable.

We have version-specific specs for the values that have configuration
data, and the version is set in the driver (so may be considered
reliably present).

Some of the 'darwinN.h' content has become dead code, and the reminder
is either conditionalised on version information (or is setting values
used as fall-backs in cross-compilations).

With the changes needed for Darwin20 / macOS 11 the 'darwnN.h' headers
are now too unwieldy to be useful - so this series moves the relevant
specs definitons to the common 'darwin.h' header and then finally uses
the config.gcc script to supply the fall-back defaults for cross-
compilations.

We can then delete all but the main header, since the darwinN.h are
unused.

This change moves a spec from darwin10.h to the main darwin.h
target header.

tested on darwin8, 9, 16, 19, 20, x86_64-linux-gnu
pushed,
thanks
Iain

Hi,

There is no need to make the LINK_GCC_C_SEQUENCE_SPEC conditional on
configuration parameters, it is adequately conditionalized on the
macosx-version-min.

Hi,

Darwin defines ASM_OUTPUT_ALIGNED_DECL_COMMON which is used in
preference to ASM_OUTPUT_ALIGNED_COMMON, which makes the latter
definition dead code.  Remove this.

Hi

The darwinN.h headers (with the sole exception of darwin7.h,
which contains a target macro definition) now only contain
values that set fall-backs for cross-compilations, these can
be provided from the config.gcc script which means we no longer
need the darwinN.h - so delete them.

tested as per part0,
pushed to master
Iain

gcc/ChangeLog:

	* config.gcc: Compute default version information
	from the configured target.  Likewise defaults for
	ld64.
	* config/darwin10.h: Removed.
	* config/darwin12.h: Removed.
	* config/darwin9.h: Removed.
	* config/rs6000/darwin8.h: Removed.
