* Change SometimesInlineFunction to "return i * i * 3;"H.J. Lu2014-12-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | The debug_msg test has 2 implementations of SometimesInlineFunction: int SometimesInlineFunction(int i) { return i; } int SometimesInlineFunction(int i) { return i * i; } and One Definition Rule (ODR) violation detection expects they will be compiled into functions of different sizes. Hower, on x86, GCC 4.7 and newer compile them into functions of the same size and ODR violation detection test fails. This patch changes int SometimesInlineFunction(int i) { return i; } to int SometimesInlineFunction(int i) { return i * i * 3; } so that it will be compiled into a function of larger size. PR gold/14608 * testsuite/debug_msg.cc (SometimesInlineFunction): Changed to "return i * i * 3;".

* With -pie and x86, the linker complains if it sees a PC-relative relocationSriraman Tallam2014-05-132-10/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | to access a global as it expects a GOTPCREL relocation. This is really not necessary as the linker could use a copy relocation to get around it. This patch enables copy relocations with pie. Context: This is useful because currently the GCC compiler with option -fpie makes every extern global access go through the GOT. That is because the compiler cannot tell if a global will end up being defined in the executable or not and is conservative. This ends up hurting performance when the binary is linked as mostly static where most of the globals do end up being defined in the executable. By allowing copy relocs with fPIE, the compiler need not generate a GOTPCREL(GOT access) for any global access. It can safely assume that all globals will be defined in the executable and generate a PC-relative access instead. Gold can then create a copy reloc for only the undefined globals. gold/ * symtab.h (may_need_copy_reloc): Remove check for position independent code. * x86_64.cc (Target_x86_64<size>::Scan::global): Add check for no position independence before pc absolute may_need_copy_reloc call.

* Fix problem where -u is ignored when a weak undef is seen.Cary Coutant2014-02-065-3/+176
| | | | | | | | | | | | | | | | | | | | | When the linker has a weak undefined symbol, it normally does not select an archive library member just to satisfy the reference. If the same symbol is also listed in a -u option, however, we should select the archive library member. This patch reorders the code in Library_base::should_include_member so that the additional checks are performed in the case of a weak undef. gold/ 2014-02-06 Cary Coutant <ccoutant@google.com> * archive.cc (Library_base::should_include_member): Reorder code to check for -u option if a weak undef has already been seen. * testsuite/Makefile.am (weak_undef_test_2): New test case. * testsuite/Makefile.in: Regenerate. * testsuite/weak_undef_file3.cc: New file. * testsuite/weak_undef_file4.cc: New file. * testsuite/weak_undef_test_2.cc: New file.
* Fix problems with the --dynamic-list option.Cary Coutant2014-02-059-3/+321
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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_.
