[genmultilib] Update basic multilib configuration

The standard arm-eabi configuration comes with a basic set of multilibs that
are suitable mostly for simple testing of the compiler in various
configurations.  We try to keep the number of libraries build small so
that build times do not become too onerous.

Using the new auto-fp selection code we can now cover all supported
architectures except for those with single-precision only FP units with
just 4 multilibs.  This is done with the rewrite of t-arm-elf.  Now that we
canonicalize -mcpu into suitable -march definitions we don't need to match
CPU names to architectures any more; the driver will do this for us.

I also noticed whilst writing this patch that the existing MULTILIB_DEFAULTS
setting in the compiler was causing more problems than it was worth; and
furthermore was simply wrong if the compiler is ever configured with
--with-mode, --with-float or --with-endian.  The remaining options also
pertained to pre-eabi builds and aren't interesting today either.  It
seemed best to just delete the definition entirely.

Before this patch series it wasn't really possible to not have an FPU;
it was always there, even if the hardware didn't really support it.

real.  Consequently, when the -mfloat-abi switch is set to softfp

soft-float ABI, but can use FP instructions if they are available.
To support this we have to separate out TARGET_HARD_FLOAT into two

but might not be available at this time (the distinction is important
because they might be enabled by an attribute during the compilation).

[arm] Rewrite -march and -mcpu options for passing to

The assembler does not understand all the '+' options accepted by the

and just pass the raw architecture or cpu name through to the

turn on or off individual features.  We already do something similar

further.  This patch also fixes a possible bug by ensuring that the
limited string copy is correctly NUL-terminated.

While messing with this code I've also taken the opportunity to clean up

Recognize '-' as special -MF argument (write to stdout)

Sometimes it is useful to generate pre-processed output to a file and
the dependency information to stdout for further analysis/processing.
For example:

g++ -E -MD -fdirectives-only -o test.ii test.cxx

This will generate the dependency information to test.d (as per the
documentation). While changing this behavior is probably unwise, one
traditional (e.g., supported by -o) way to handle this is to recognize
the special '-' file name as an instruction to write to stdout:

g++ -E -MD -fdirectives-only -o test.ii -MF - test.cxx

Currently this will create a file named '-'. The included patch
changes this behavior to write to stdout.

Note also that Clang has supported this from at least version 3.5.

7 years agocmd/cgo: make _cgo_flags consistent across runs
Ian Lance Taylor [Wed, 14 Jun 2017 13:59:02 +0000 (13:59 +0000)]
cmd/cgo: make _cgo_flags consistent across runs

    The go tool will pass -I objdir as one of the flags, where objdir is
    the temporary build directory. Remove that from _cgo_flags: we don't
    need it, and it will be different each time.

    Sort the flags to avoid the unpredictable map iteration order.

    This matters for gccgo because for a package that uses cgo, the go
    tool when building for gccgo will store the _cgo_flags file in the
    archive. That means that we want to generate identical _cgo_flags for
    every run.

    The test for this is the cmd/go testsuite, to follow in a future CL.
