2017-12-01Disallow --incremental with -pie and force -no-pie for incremental tests.Cary Coutant1-0/+2
This is a partial fix for the gold testsuite failures documented in PR 21090. The use of -fpie triggers some mov-to-lea optimizations that are not compatible with incremental linking, so those optimizations need to be disabled. We also diagnose the attempt to use -pie with incremental linking, and force -no-pie for the incremental tests in case the build has been configured to have GCC pass -pie all the time. We still have a problem where compiling with -fpie results in some GOT entries even when linking with -no-pie. This combination still causes test failures because we are not updating the GOT entries in an incremental update link. gold/ PR gold/21090 * incremental.cc (Sized_relobj_incr::do_relocate): Fix comment. * options.cc (General_options::finalize): Disallow -pie with incremental linking. * x86_64.cc (Target_x86_64::Scan::local): Don't do mov-to-lea or callq-to-direct optimizations for incremental links.

2017-12-01Fix internal error from command line with unbalanced --start-lib/--end-lib.Benjamin Peterson1-0/+6
The problem is that while the command line isn't trivially empty, it contains no input files. As gold tries to configure the number of threads to use based on the number of input files, this causes the assertion failure above. Fix this problem by making the logic in gold.cc more robust and also adding a better error message about --start-lib to options.cc. gold/ PR gold/22406 * gold.cc (queue_initial_tasks) Check for number of real input files. * options.cc (Command_line::process) Check for unterminated --start-lib options. * testsuite/Makefile.am: Add new test script. * testsuite/Makefile.in: Regenerate. * testsuite/check_empty_command_lines.sh: New test script.

2015-02-16Fix --dynamic-list so that symbols not in the list are still exported.Cary Coutant1-7/+0
In PR 13577, the complaint was that -Bsymbolic was overriding the binding behavior for symbols listed in the --dynamic-list by setting the DT_SYMBOLIC tag in the dynamic table. In reading the Gnu ld manual, I decided that --dynamic-list should be mutually exclusive of -Bsymbolic, and modified gold so that --dynamic-list would treat symbols listed as preemptible, and all other symbols as internally bound. I was wrong. PR 16992 shows that with --dynamic-list (and not -Bsymbolic), a symbol not listed in the dynamic list is being internally bound within the shared library, but because it's still in the dynamic symbol table, we expose it to a COPY relocation, and things go really bad from there. (I can reproduce the same failure, simply by turning on -Bsymbolic-functions with the Gnu linker. Even though the symbol is bound internally, it's still exported to the dynamic symbol table, and is exposed to a COPY relocation.) I've backed out part of the fix for PR 13577, and -Bsymbolic (or -Bsymbolic-functions) can now be used with --dynamic-list, but if the two are used together, we do not set DT_SYMBOLIC or DF_SYMBOLIC (this matches Gnu ld behavior). We now treat symbols listed in the dynamic list as premptible, but we do not automatically treat symbols not listed there as non-premptible. gold/ PR gold/13577 PR gold/16992 * layout.cc (Layout::finish_dynamic_section): Don't set DT_SYMBOLIC or DF_SYMBOLIC if --dynamic-list option is used. * options.cc (General_options::finalize): --dynamic-list is not mutually exclusive with -Bsymbolic. * symtab.h (Symbol::is_preemptible): Don't exclude dynamic symbols not listed in --dynamic-list. * testsuite/Makefile.am (dynamic_list_lib2.so): Add -Bsymbolic-functions. * testsuite/Makefile.in: Regenerate.

2014-02-05Fix problems with the --dynamic-list option.Cary Coutant1-0/+9
PR gold/13577 complains that even though symbols listed in the --dynamic-list script are exported, they are still bound symbolically if -Bsymbolic is also used. There are two underlying problems here. First, -Bsymbolic should be overridden by --dynamic-list, since the dynamic list provides an explicit list of symbols that are not bound within the library, and if we go ahead and set DT_SYMBOLIC, then the dynamic loader will bind it within the library anyway. Second, gold did not properly identify the symbols listed in the file as preemptible. PR gold/16530 complains that symbols listed in the --dynamic-list script can still be garbage collected. I've fixed this by checking the symbols as they're added to the symbol table. (Unlike the --export-dynamic-symbol option, we can't iterate over the list, because the --dynamic-list script can have wildcards in it.) gold/ 2014-02-05 Cary Coutant <ccoutant@google.com> PR gold/13577 * options.cc (General_options::parse_dynamic_list): Set have_dynamic_list_.
