2017-07-04[AArch64] Remove useless and incorrect assertionJiong Wang2-7/+5
The outer caller elf_link_output_extsym in elflink.c is a traverse function on all external symbol, and it will only call *finish_dynamic_symbol if some conditions is meet. It is executed conditionally. If the condition to trigger that assertion is satisified, it then won't satify the outer check in finish_dynamic_symbol, so *finish_dynamic_symbol won't be called that the assertion is expected to be dead code. If elf_link_output_extsym is a traverse function that unconditionally called on external symbols decided to be exported, then an assertion to make sure these symbols are in sane status might make sense. bfd/ * elfnn-aarch64.c (elfNN_aarch64_finish_dynamic_symbol): Remove the sanity check at the head of this function.

2017-07-03Support %Lx, %Lu, %Ld in _bfd_error_handler formatAlan Modra5-46/+82
One way to print 64-bit bfd_vma or bfd_size_type values on 32-bit hosts is to cast the value to long long and use the 'll' modifier in printf format strings. However, that's awkward because we also support the Microsoft C library printf that uses 'I64' as a modifier instead, and having variants of translated strings would not endear us to the translation project. So, rewrite the 'll' modifier in _doprint for Microsoft. Even with that capability it's not so nice for 32-bit code to need casts to long long, so this patch makes 'L' a modifier for bfd_vma rather than an alias for 'll'. I've then used the new 'L' modifier to fix selected format strings. * bfd.c (_doprnt): Rewrite "ll" and "L" modifiers to "I64" for __MSVCRT__. Support "L" modifier for bfd_vma. Formatting. * elf.c (setup_group): Use "Lx" to print sh_size. (_bfd_elf_setup_sections): Remove unnecessary cast and print unknown section type in hex. (copy_special_section_fields): Style fix.

2017-06-29[AArch64] Remove duplicated code when handling some GOT relocations typesJiong Wang3-92/+36
There are quite a few duplicated code supporting several GP based relocation types. They are: BFD_RELOC_AARCH64_LD64_GOTOFF_LO15 BFD_RELOC_AARCH64_MOVW_GOTOFF_G0_NC BFD_RELOC_AARCH64_MOVW_GOTOFF_G1 These relocation types are supposed to be used for large memory model PIC/pic mode under which we will have an initialized GP register points to the base of GOT table, then these relocations are supposed to put the distance between GOT entry and GOT table base address into the related instructions. So, the parameters required to calculate the relocation should be the same as BFD_RELOC_AARCH64_LD64_GOTPAGE_LO15 etc, all of them are require the GOT entry address and GOT table base address to perform the relocation. This patch has removed those duplicated code when handling above listed relocation types, grouped them with others as relocation types that are require GOT table base address during performing relocation, reused the existed GOT handling code. The relocation calculation for these types before and after this patch should be identical. bfd/ * elfnn-aarch64.c (aarch64_relocation_aginst_gp_p): New function. (elfNN_aarch64_final_link_relocate): Delete duplicated code for BFD_RELOC_AARCH64_LD64_GOTOFF_LO15, BFD_RELOC_AARCH64_MOVW_GOTOFF_G0_NC, BFD_RELOC_AARCH64_MOVW_GOTOFF_G1. * elfxx-aarch64.c (_bfd_aarch64_elf_resolve_relocation): Optimize the support for them.

2017-06-27Fix PR 13402Senthil Kumar Selvaraj2-1/+11
Fix incorrect adjustment of diff relocs when relaxing, and thus the resulting source line to address mismatch. Fix two issues when adjusting diff relocs to account for deleted bytes. 1. Don't adjust the difference if the end address is the shrinked insn's address i.e. use < instead of <=. The relaxation code deletes count bytes from or after shrinked_insn_address, so the difference between start_address and end_address should remain unchanged in this case. 2. Adjust the reloc addend if the difference is to be adjusted and symval + reloc addend is past the shrinked insn address. This is because for a typical sym1 - sym2 diff reloc, sym1 is .text + irel->r_addend, and the addend should be reduced to account for the shrinked insn. For example, assume the reloc value is .text + 0x8 with .text = 0, the diff value in the object file = 0x4, and shrinked_insn_address = 0x4 with count = 0x2. Then the existing code writes 0x2 into the object file to account for the deleted bytes, as shrinked_insn_address lies between 0x8 and 0x8 - 0x4 = 0x4, but leaves the addend as is. The next time the reloc is looked at, the code sees if a shrinked_insn_address lies between 0x8 and 0x8 - 0x2 = 0x6, instead of 0x6 and 0x4. If there happens to be one, then the diff value in the object file ends up getting reduced again. bfd/ 2017-06-27 Senthil Kumar Selvaraj <senthil_kumar.selvaraj@atmel.com> PR ld/13402 * elf32-avr.c (elf32_avr_adjust_diff_reloc_value): Adjust reloc addend if necessary.

2017-06-26Check file size before getting section contentsH.J. Lu3-9/+26
Don't check the section size in bfd_get_full_section_contents since the size of a decompressed section may be larger than the file size. Instead, check file size in _bfd_generic_get_section_contents. PR binutils/21665 * compress.c (bfd_get_full_section_contents): Don't check the file size here. * libbfd.c (_bfd_generic_get_section_contents): Check for and reject a section whoes size + offset is greater than the size of the entire file.

2017-06-26LD: Fix .startof.SECNAME/.sizeof.SECNAME tests for MIPS/IRIXMaciej W. Rozycki1-0/+2
Correct .startof.SECNAME/.sizeof.SECNAME tests for MIPS/IRIX targets, complementing commit dc74becf498f ("ld: Add tests for -Ur") and commit da614360f520 ("ld: Add tests for .startof.SECNAME/.sizeof.SECNAME") with subsequent updates, and in reference to commit cbd0eecf261c ("Always define referenced __start_SECNAME/__stop_SECNAME") and commit 7dba9362c172 ("Rewrite __start and __stop symbol handling"). These targets set the STT_OBJECT type for non-function symbol references, according to `elf_frob_symbol' code in gas/config/obj-elf.c: /* The Irix 5 and 6 assemblers set the type of any common symbol and any undefined non-function symbol to STT_OBJECT. We try to be compatible, since newer Irix 5 and 6 linkers care. However, we only set undefined symbols to be STT_OBJECT if we are on Irix, because that is the only time gcc will generate the necessary .global directives to mark functions. */ if (S_IS_COMMON (symp)) symbol_get_bfdsym (symp)->flags |= BSF_OBJECT; if (strstr (TARGET_OS, "irix") != NULL && ! S_IS_DEFINED (symp) && (symbol_get_bfdsym (symp)->flags & BSF_FUNCTION) == 0) symbol_get_bfdsym (symp)->flags |= BSF_OBJECT; and consequently entries in the symbol table listing from `readelf' produced with these tests do not match the NOTYPE pattern expected, causing test suite failures: FAIL: ld-elf/sizeofa FAIL: ld-elf/sizeofc FAIL: ld-elf/startofa FAIL: ld-elf/startofc specifically with the `mips-sgi-irix5' and `mips-sgi-irix6' targets. Given that it does not matter for the feature covered by these tests whether the type of the symbols produced is STT_NOTYPE or STT_OBJECT adjust the problematic cases to accept either type, removing the failures observed. ld/ * testsuite/ld-elf/sizeofa.d: Also accept the OBJECT type for the symbols examined. * testsuite/ld-elf/sizeofc.d: Likewise. * testsuite/ld-elf/startofa.d: Likewise. * testsuite/ld-elf/startofc.d: Likewise.
