* Better overflow checking for powerpc64 relocationsAlan Modra2014-03-082-18/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | R_PPC64_ADDR16 is used in three contexts: - .short data relocation - 16-bit signed insn fields, eg. addi - 16-bit unsigned insn fields, eg. ori In the first case we want to allow both signed and unsigned 16-bit values, the latter two ought to error if the field exceeds the range of values allowed for 16-bit signed and unsigned integers respectively. These conflicting requirements meant that ld had to choose the least restrictive overflow checks, and thus it is possible to construct testcases where an addi field overflows but is not reported by ld. Many relocations dealing with 16-bit insn fields have this problem. What's more, some relocations that are only ever used for signed fields of instructions woodenly copied the lax overflow checking of R_PPC64_ADDR16. bfd/ * elf64-ppc.c (ppc64_elf_howto_raw): Use complain_overflow_signed for R_PPC64_ADDR14, R_PPC64_ADDR14_BRTAKEN, R_PPC64_ADDR14_BRNTAKEN, R_PPC64_SECTOFF, R_PPC64_ADDR16_DS, R_PPC64_SECTOFF_DS, R_PPC64_REL16 entries.

* Fix problem where -u is ignored when a weak undef is seen.Cary Coutant2014-02-066-41/+224
| | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | PR binutils/15435 complains that gold issues a visibility error for an weak undefined symbol with hidden visibility. The message should be suppressed if the symbol is a weak undef. An earlier patch to add an extra note about key functions when a class's vtable symbol is undefined missed a case where the reference to the vtable came from a shared library. This patch moves the check to a lower-level routine that catches both cases. gold/ 2014-02-05 Cary Coutant <ccoutant@google.com> * errors.cc (Errors::undefined_symbol): Move undef vtable symbol check to here. * target-reloc.h (is_strong_undefined): New function.

* Fix problems with the --dynamic-list option.Cary Coutant2014-02-0513-6/+347
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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_.

* Report overflow on PowerPC64 @h and @ha relocations.Alan Modra2013-10-302-39/+98
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This changes the behaviour of @h and @ha on PowerPC64 to report errors on 32-bit overflow. The motivation for this change is that on PowerPC64, most uses of @h and @ha modifiers and their corresponding relocations are to build up 32-bit offsets. We'd like to know when such offsets overflow. Only rarely do people use @h or @ha with the high 32-bit modifiers to build a 64-bit constant. Those uses will now need to use two new modifiers, @high and @higha, if the constant isn't known at assembly time. For now, we won't report overflow at assembly time.. This also fixes an error when applying some of the HIGHER and HIGHEST relocations. include/elf/ * ppc64.h (R_PPC64_ADDR16_HIGH, R_PPC64_ADDR16_HIGHA, R_PPC64_TPREL16_HIGH, R_PPC64_TPREL16_HIGHA, R_PPC64_DTPREL16_HIGH, R_PPC64_DTPREL16_HIGHA): New.
