GNU as: move deprecation message after option parsing

2020-05-18T16:07:14+00:00

Some cmake test parses the output of the first line of as --version, and
emits an error if it does not contain some expected strings:

Checking whether the ASM compiler is GNU using "--version" did not match
"(GNU assembler)|(GCC)|(Free Software Foundation)"

Emit the deprecation message later, after parsing argv and thus --version.

GNU as: print a deprecation warning on program start

2020-05-06T01:08:19+00:00

GNU as 2.17.50 will be removed before FreeBSD 13.

gas: mark dwarf2_loc_mark_labels as extern

2020-03-28T03:58:57+00:00

Compiling with -fno-common complains as this header's included in multiple
compilation units. In fact, the proper definition of dwarf2_loc_mark_labels
already exists in dwarf2dbg.c, so simply mark this declaration with extern.

binutils: Fix bugs found by -Wpointer-compare

2019-10-24T22:34:48+00:00

The MIPS bug was introduced by upstream commit 7403cb630, which failed
to account for the additional indirection introduced and also dropped
one of the checks; change it to the standard "NULL-or-empty" check as
used elsewhere in BFD, which is also what upstream now has.

as: add deprecation notice to the man page

2019-08-01T19:01:27+00:00

In the future FreeBSD will ship without GNU binutils 2.17.50.  Add a
note advising users who require GNU as to install the binutils port
or package.

Note that on armv7, arm64, amd64, i386 we currently ship only two
binutils tools (as and objdump).  A deprecation notice was added to
objdump's man page some time ago.

objdump: be explicit that GNU objdump that will be removed

2019-08-01T14:42:41+00:00

We may install llvm-objdump as objdump (see review D18307) or just
provide no /usr/bin/objdump, but either way GNU objdump won't be
installed in the future.
