Oddly, config.sub converts a duple ending in -elf for these target to
-unknown-none, which means they aren't seen as elf targets by
binutils. So, counter that. This exposes a number of testsuite
issues (ones you would have seen if configuring with a full triple,
say m68hc11-unknown-elf).

When using run_dump_test with the map option to compare the linker map
file produced, no additional dump program should be required. A dump
program can still be given if needed, but leaving it off will no longer
produce an error.
ld/testsuite/ChangeLog:
* ld/ld-lib.exp (run_dump_test): When using the map option, no
program is required.
The run_dump_test mechanism supports options error and warning, which
allow regexp to be specified within the test file, these regexp are
matched against the stderr output from the linker.
Similar dump test style functions for gas and gdb also support file
based matching versions of these options; the patterns are placed into a
file which the test driver then references. It is sometimes clearer,
when the pattern to be matched spans multiple lines if the patterns can
be placed into a separate file.
This patch adds new options error_output and warning_output for the
linker run_dump_test function. These new options take a filename
parameter, this file is then used (with regexp_diff) to compare against
the linker output.
ld/testsuite/ChangeLog:
* ld/ld-lib.exp (run_dump_test): Add error_output and
warning_output options.
run_host_cmd_yesno should set errcnt and warncnt to 0. Otherwise, they
may leak to the next run.
* lib/ld-lib.exp (run_host_cmd_yesno): Set errcnt and warncnt
to 0.
Add a new option 'map' to the ld run_dump_test mechanism. When the
'map' option is given run_dump_test will ensure that there is a
-Map=MAPFILE present in the linker command line, adding one if needed.
The MAPFILE is then compared with the file passed to the new 'map'
option using the regexp_diff function. This should make it slightly
easier to write tests that check the linker mapfile output.
The only test I found that already compares mapfile content is updated
to use the new mechanism.
ld/testsuite/ChangeLog:
* ld-scripts/overlay-size.d: Add 'map' option.
* ld-scripts/overlay-size.exp: Remove manual check of mapfile.
* lib/ld-lib.exp (run_dump_test): Add support for new 'map'
option, checking linker mapfile output.
Mention that readelf can be used as a test program in the comment of
run_dump_test.
ld/testsuite/ChangeLog:
* lib/ld-lib.exp (run_dump_test): Extend comment to mention
readelf.
* ld-scripts/sysroot-prefix.exp: Log $ld_sysroot. Handle sysroot
== "/" as a separate sysroot-configuration with separable
test-types.
(sysroot_prefix_tests): Include all existing sysroot tests in
sysroot == "/" tests except exclude those where a --sysroot option
is not specified.
* lib/ld-lib.exp (check_sysroot_available): Rewrite to use
--print-sysroot instead of relying on error code from using
--sysroot=... Also, set $ld_sysroot.
The reason we exclude not just the failing "full-path =-prefixed
without" but also the passing "plain =-prefixed without but -Lpath"
for sysroot == "/" is that for the latter to succeed, we have to make
assumptions about the system not having a /sysroot directory or
assumptions about its contents etc.
When passing --enable-targets=all --enable-64-bit-bfd (the
latter not required for a "64-bit-host" of course) the ld --help
output got too much to handle for poor tcl (or maybe dejagnu is
to blame) and remote_exec exited with an error, so the
configuration being tested was mishandled as being a
sysroot-less configuration. Using --version instead of --help
would work too, but the new --print-sysroot option calls for
nominal coverage, so why not use that instead.
* lib/ld-lib.exp (check_lto_fat_available): New.
(check_lto_available): Remove -ffat-lto-objects test.
* ld-plugin/lto.exp: Use [list ] rather than { } to set up list
variables, allowing substition of vars. Set lto_fat and plug_opt
and add to various tests.
toolchain that just contains the binutils - ie without a compiler.
* lib/ld-lib.exp (check_lto_available): Check that a compiler is
available before testing for LTO support.
Various ld-elf/shared.exp and ld-plugin/lto.exp tests simply appended
the testsuite -B options intended to force gcc use the linker under test.
This fails if $CC itself has -B options, as when setting CC to run gcc
out of a build directory. Net result is that tests were run using
the gcc build dir collect-ld.
* config/default.exp: Don't make tmpdir/gas. Put as symlink into
tmpdir/ld.
(gcc_gas_flag, gcc_ld_flag): Delete.
(gcc_B_opt, ld_L_opt): New globals.
ld-elf/shared.exp: Remove all refs to gcc_gas_flag and gcc_ld_flag.
ld-plugin/lto.exp: Likewise.
lib/ld-lib.exp (run_host_cmd): Add gcc_B_opt and ld_L_opt here.
(ld_simple_link): Remove -B handling now that this is done in
run_host_cmd. Simplify.
(default_ld_compile): Simplify.
(check_lto_available): Use run_host_cmd_yesno.
(check_lto_shared_available): Likewise.
libdummy.a is used to make run_cc_link_tests compile objects and
archive them. libdummy.a isn't used. What we're really doing is
preventing a final link. So do that directly.
* lib/ld-lib.exp (run_ld_link_tests): Stop after assembling objects
if binfile is empty.
(run_ld_link_exec_tests, run_cc_link_tests): Likewise. Tidy
status checks.
* ld-plugin/lto.exp: Don't use libdummy.a trick to compile objects.
Instead use an empty output file.
ld/testsuite/
* lib/ld-lib.exp: Add objcopy_objects command to run_dump_test.
This allows each input object to be optionally run through
objcopy before linking.
