2016-08-10Fix extraneous complaints about missing expected TLS relocation.Cary Coutant4-4/+16
With some versions of gas, the call to tls_get_addr uses a GOTPCREL relocation instead of a GOTPCRELX relocation. We should allow for that when skip_call_tls_get_addr_ is true. We should also build the test objects with the in-tree assembler. This patch also fixes some cascading error messages caused by not resetting the skip_call_tls_get_addr_ flag after printing the error. gold/ PR gold/20216 * x86_64.cc (Target_x86_64::Relocate::relocate): Add check for R_X86_64_GOTPCREL.

2016-08-10Fix improper handling of R_SPARC_GOTDATA_OP_LOX10 relocation.James Clarke2-7/+13
The fall-through in Target_sparc::Relocate::relocate for R_SPARC_GOTDATA_OP_LOX10 is currently R_SPARC_GOT13, but should clearly be R_SPARC_GOT10. GCC has been seen to emit a sethi/xor rather than a sethi/or sequence to load a 32-bit immediate, but if R_SPARC_GOT13 is used then bits 10-12 get zeroed out as both the sethi and xor immediates contain them. gold/ PR gold/20442 * sparc.cc (Target_sparc::Relocate::relocate): R_SPARC_GOTDATA_OP_LOX10 should fall back on R_SPARC_GOT10, not R_SPARC_GOT13.

2016-06-29Fix gold testsuite failure with GCC 6.Cary Coutant2-1/+6
With GCC 6 when not using -static-libstdc++, the operator delete(void*) function is defined in the shared C++ support library, rather than in the main program.

2016-03-30Don't override definition a shared object by one in a later shared object.Cary Coutant2-0/+13
In PR 16979, a reference to malloc is being resolved to an unversioned reference in libmalloc.so. When linked with --as-needed, however, the dynamic table does not list libmalloc.so as a DT_NEEDED library. If we have a reference to an unversioned symbol in a shared object, and we later see a versioned definition in another shared object, we were overriding the first definition with the second in the process of defining the default version. As a result, we no longer think that the first shared object was actually needed to resolve any symbols, and we don't list it as a DT_NEEDED library. This patch fixes the problem by treating the two definitions as separate symbols, so the second definition does not override the first. 2016-03-30 Cary Coutant <ccoutant@gmail.com> gold/ PR gold/16979 * symtab.cc (Symbol_table::define_default_version): Check for case where symbols are both in different shared objects.

2016-03-21Fix problem where gold fails to issue an undefined symbol error during LTO.Cary Coutant7-2/+143
During LTO, if (1) an IR file contains a COMDAT group that is kept, (2) a later non-claimed file contains the same group, which we discard, and (3) the plugin fails to provide a definition of the symbols in that COMDAT group, gold silently resolves any references to those symbols to 0. This patch adds a check for a placeholder symbol when deciding whether to issue an undefined symbol error. It also adds an extra note after any undefined placeholder symbol error that explains that a definition was expected from the plugin. gold/ PR gold/19842 * errors.cc (Errors::undefined_symbol): Add info message when symbol should have been provided by a plugin. * target-reloc.h (issue_undefined_symbol_error): Check for placeholder symbols defined in discarded sections. * testsuite/Makefile.am (plugin_test_9b): New test case. * testsuite/Makefile.in: Regenerate. * testsuite/plugin_test_9b_elf.cc: New test source file. * testsuite/plugin_test_9b_ir.cc: New test source file.
