2017-09-28Skip the PR 14918 linker test for ARM targets.Nick Clifton1-3/+13
I am applying a patch that has been lying around in the Fedora binutils sources for a while. It skips the PR14918 linker test for ARM based targets. This test checks that libgcc is not included in a link of an empty executable. This works for most targets, but on the ARM the crt1.o startup code calls __libc_csu_init which is in /usr/lib/libc_nonshared.a(elf-init.oS). This in turn needs __aeabi_unwind_cpp_pr0@@GCC_3.5 which is provided by libgcc_s.so.1, and so the test fails.

2017-04-20Handle symbol defined in IR and referenced in DSOH.J. Lu3-0/+33
We need to make an IR symbol visible if it is defined in an IR object and referenced in a dynamic object. When --as-needed is used, since linker removes the IR symbol reference of the dynamic object if the dynamic object isn't needed in the first pass, the IR definition isn't visible to the dynamic object even if the dynamic object becomes needed in the second pass. Add dynamic_ref_after_ir_def to bfd_link_hash_entry to track IR symbol which is defined in an IR object and later referenced in a dynamic object. dynamic_ref_after_ir_def is preserved when restoring the symbol table for unneeded dynamic object. bfd/ PR ld/21382 * elflink.c (elf_link_add_object_symbols): Preserve dynamic_ref_after_ir_def when restoring the symbol table for unneeded dynamic object. include/ PR ld/21382 * bfdlink.h (bfd_link_hash_entry): Add dynamic_ref_after_ir_def. ld/ PR ld/21382 * plugin.c (is_visible_from_outside): Symbol may be visible from outside if dynamic_ref_after_ir_def is set.

2017-02-16ld: Add additional checking for warnings/errors in testsuiteAndrew Burgess1-2/+4
This commit adds new actions to the run_cc_link_tests mechanism in the linker testsuite. Previously this procedure could take a parameter containing a regular expression that would be matched against warnings from the linker. After this commit the warnings parameter is removed, instead, the actions list can contain the actions 'warning', 'error', 'warning_output', or 'error_output'. The action names are chosen to match the actions already present in the run_dump_test procedure. These new actions allow for the current warning checking, but also allow for checking of errors using a regular expression. More interestingly, the *_output actions allow for the warning/error patterns to be placed in a separate file. The small number of tests that make use of the warning parameter have been updated to the new mechanism. Later commits will make use of the new features added in this commit. ld/ChangeLog: * testsuite/lib/ld-lib.exp (run_cc_link_tests): Add warning, error, warning_output, and error_output actions. Remove separate warnings parameter. * testsuite/ld-elf/shared.exp (build_tests): Updated to use 'warning' action. * testsuite/ld-plugin/lto.exp (lto_link_tests): Likewise.

2017-01-02Run more ld tests when not nativeAlan Modra2-6/+1
Many of the ld tests are not run for cross builds, in some cases because the test needs to run a newly linked executable, and in others simply because it was easier to write the test for native only. Even when a test needs to run, it's good to compile and link to exercise the linker. So that's what this patch does. I've also rid us of the old ld_link procedure with all the HOSTING_CRT0 etc. setup. It's much simpler to just link with $CC. This does mean that a cross build with cross-compiler installed but no cross C-library will give lots of failures. If that turns out to be too annoying, I guess we can write a tcl procedure to detect it and not run all the extra tests. * Makefile.am (bootstrap): Delete rule.

2016-07-19ld: Restore file offset after a plugin fails to claim a fileAndrew Burgess2-1/+32
When using the plugin interface to claim an input file the claim method from (possible) many plugins can be called on an input file. If these claim methods read content from the input file then the file offset stored in the underlying file descriptor will change. As we share a file descriptor between the plugin interface (created with dup in ld/plugin.c:plugin_object_p) and the input bfd object, then any changes to the file offset in the file descriptor will effect the bfd object. Also, as the changes to the file offset did not originate from calls through the bfd interface, but instead came from the plugin directly, then the bfd will not be aware that the file offset has changed. This is a problem as the bfd library caches the file offset. If the plugin decides not to claim an input file then, currently, we leave the bfd in a state where the actual file offset is out of sync with the cached file offset. This problem came to light after a recent commit 7d0b9ebc1e0079271a7c7737b53bc026525eab64 (Don't include libbfd.h outside of bfd, part 6) however, I don't believe that commit actual introduces the bug, it just exposed the existing issue. This commit solves the problem by backing up and restoring the file offset for the file descriptor of the input file. The restore is only done if the plugin does not claim the input file, as it is in this case that the bfd library might be used again to try and identify the unclaimed file. ld/ChangeLog: * plugin.c (plugin_call_claim_file): Restore the file offset after an unsuccessful attempt to claim a file. * testplug.c (bytes_to_read_before_claim): New global.

LTO may optimize out a plugin symbol, which is also referenced by a non-IR file. When that happens, we should mark the plugin symbol undefined.

2014-07-08Run ar with --plugin for LTO 11 testAlan Modra1-1/+14
Objects built with -fno-fat-lto-objects (the default for gcc-4.9) have no normal symbols, except things like __gnu_lto_slim. These useless symbols are the ones put into the archive index, and of course nothing references them so no objects are extracted by the linker. Running ar with --plugin changes ar behaviour to put the lto symbols into the archive index. PR 17112 * ld-plugin/lto.exp: When building liblti-11.a, pass --plugin path_to_gcc/liblto_plugin.so to ar.
2014-07-07Ensure ld testsuite gcc -B options precede $CC -B optionsAlan Modra1-2/+2
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.
