As ramping up clock speeds becomes harder and we see more parallel cores
being used to extend Moore's Law, there is also a growing number of
heterogenous
systems that have fully programmable cores with different architectures, e.g.
Cell, ARCompact / MXP, CPU / GPU combinations.
It is desirable that high-level optimizers can consider characteristics of
all the target architectures in a system to make decisions to move and/or
clone functions from one architecture to another, and then emit code -
including any needed interworking glue code - for all the targeted processors.
This requires that more than one backend is linked into the compiler, and
rtl optimizers can handle different targets.
Some code will intrinsically be driven by different code/data for differet
targets, e.g. the code from config/<target> and the insn-* files will be
different. Also, where heavy use of target or target-dependent generated
macros is made, using different object files for different targets makes sense.
To a first order of approximation, we can say trees and their passes are
target-independent, while rtl and its passes are target-dependent.
This might classify some general rtl handling code as target dependent even if
this is not actually true, or if dependencies could sensibly be factored out
with new target hooks, but the only practical downside of this that that
multi-target configurations will have larger binaries than necessary.
Once the basic infrastructure is in place, each module that is marked as
target specific can be scrutinized if it actually is - or can be reasonably
made - target independent.
The interface of our target hooks will need a few changes. 'enum machine_mode'
will have to be generated to include modes for all the targets, so that the
same value means the same across all targets on which the mode exists.
On the other hand, types 'enum reg_class' are intrinsically target-specific.
different enums can have different width, so in order to have a well-defined
function type that can be safely used for calls, the targetm member
declarations have to use an integer type for such argument / return values.
This PR depends on PR44433 inasmuch as using namespaces to separate multiple
copies of middle end / rtl-optimizer modules requires that at least one
language front end can be built using --enable-build-with-cxx, i.e. PRs
like PR44512 must be fixed as a prerequisite; if such a configuration doesn't
work for ADA that merely means that this one language can't be used for
multi-target configurations, thus PR44362 doesn't actually block.

Sorry, I meant PR44431. But then, the remaining part of PR44362 also
doesn't block PR44566 (and not PR44433 either).

There are many target macros used outside of the RTL passes, including in
front ends, GIMPLE code, the driver, collect2 and libgcc, and all of these
would need to become hooks (or in the case of libgcc, target macros in a
separate set of headers under the toplevel libgcc/ directory so that
different headers can be used in the libgcc builds for different targets).
You'll need to figure out how to identify every macro used in those parts
of the compiler and convert it to a hook [*] (at least to the intermediate
stage of a default definition in targhooks.c that uses the macro, if you
build targhooks.c multiple times in your scheme). I'm not sure there's
much real benefit in distinguishing target macros by where they are used;
every one of them should end up being converted to a hook anyway (with
appropriate LTO work to ensure effective devirtualization is possible in a
single-target compiler). If you have a good way to identify target macros
(including those set at configure time rather than in tm.h headers) and
macros defined indirectly depending on target macros, then you can work
out exactly what does use them.
[*] The correct conversion is not always a one-to-one conversion where a
single hook replaces a single macro.
Work will also be needed outside the compiler, e.g. in the assembler which
entirely uses macros rather than hook at present, unless you arrange for
separately built assemblers for different targets to be called for the
code for each target.
