GDB has required GNU make for quite some time, and this patch applies
this approach to the sim as well. Requiring GNU make means that
automatic dependency tracking can be simple and reliable, and it also
makes other refactorings simpler.

When building with clang, we get:
error: unknown warning option '-Wmissing-parameter-type' [-Werror,-Wunknown-warning-option]
This is because clang only warns by default when encountering an unknown
warning option, and the probe for supported warning flags is done
without -Werror. All flags are therefore accepted by configure, but
then it breaks when actually compiling a source file with -Werror.
This is equivalent to this commit in gdb:
3e019bdc20eb81b91ab5bc774386201b874c0bac
gdb: Use -Werror when checking for (un)supported warning flags
We then see some other compilation errors when building with clang and
-Werror, they can be dealt with later.

This avoids duplicate tests for headers between common m4, arches,
and any other sources that would trigger header tests.

This avoids duplicate tests for functions between common m4, arches,
and any other sources that would trigger func tests.
Also manually delete known duplicate function tests between the m4,
bfin, and v850 ports.

The toplevel, common, and igen dirs all have their own code for
setting up toolchain settings. Unify all of that in a new macro.
|
|
Some sim dirs were already setting up CFLAGS_FOR_BUILD in inconsistent
ways. Move it to a common place for reuse.
|
|
Rather than require $AR be set and then default to `ar`, use the
standard AC_CHECK_TOOL helper to find a good prefixed tool. In
practice this shouldn't change much as we seem to have macros in
the tree that were already setting it up, but we shouldn't rely
on that implicitly.
|
|
All the scripts were using this implicitly already, so there's no real
change for them, but we want to call it explicitly as the CPP tool is
used to generate nltvals.def.
|
|
This file is quite large and is getting unmanageable. Split it apart
to follow aclocal best practices by putting one-macro-per-file. There
shouldn't be any real functional changes here as can be seen in the
configure script regens.
