Maciej W. Rozycki	ebf0b03c70	LD: vfinfo: Make clever formatters consistent WRT function name reporting Remove an inconsistency in linker error message processing causing that it depends on the ability to infer the name of the originating source file whether or not the name of the offending function is repeated by clever formatters for each issue reported within the function. Taking the `ld/testsuite/ld-powerpc/tocopt7.s' test case source as an example and the `powerpc-linux' target we have: $ as -gdwarf2 -o tocopt.o -a64 tocopt.s $ ld -o tocopt -melf64ppc tocopt.o tocopt.o: In function `_start': tocopt.s:35:(.text+0x14): toc optimization is not supported for 0x3fa00000 instruction. tocopt.s:49:(.text+0x34): toc optimization is not supported for 0x3fa00000 instruction. $ vs: $ as -o tocopt.o -a64 tocopt.s $ ld -o tocopt -melf64ppc tocopt.o tocopt.o: In function `_start': (.text+0x14): toc optimization is not supported for 0x3fa00000 instruction. tocopt.o: In function `_start': (.text+0x34): toc optimization is not supported for 0x3fa00000 instruction. $ Similarly with the `mips-linux' target and this source: $ cat jal-global-multi-overflow.s .text .set noreorder .space 0x2000 .align 4 .globl foo .ent foo foo: jal bar nor $0, $0 jal bar nor $0, $0 .end foo .space 0x1ff0 .align 4 .globl bar .ent bar bar: jal foo nor $0, $0 jal foo nor $0, $0 .end bar $ as -o jal-global-multi-overflow.o jal-global-multi-overflow.s $ ld -Ttext 0x1fffd000 -e foo -o jal-global-multi-overflow jal-global-multi-overflow.o jal-global-multi-overflow.o: In function `foo': (.text+0x2000): relocation truncated to fit: R_MIPS_26 against `bar' jal-global-multi-overflow.o: In function `foo': (.text+0x2008): relocation truncated to fit: R_MIPS_26 against `bar' jal-global-multi-overflow.o: In function `bar': (.text+0x4000): relocation truncated to fit: R_MIPS_26 against `foo' jal-global-multi-overflow.o: In function `bar': (.text+0x4008): relocation truncated to fit: R_MIPS_26 against `foo' $ Not only this is inconsistent, but it causes output clutter as well with redundant information. The cause for this is a check in `vfinfo' the intent of which is to print the function heading whenever (among others) the name of the source file has changed, which however does not take into account a situation where the name couldn't have been established both now and previously. Adjust the check then for this situation, yielding: $ as -o tocopt.o -a64 tocopt.s $ ld -o tocopt -melf64ppc tocopt.o tocopt.o: In function `_start': (.text+0x14): toc optimization is not supported for 0x3fa00000 instruction.

Alan Modra	f0158f4416	PowerPC dynamic relocations This patch fixes a number of issues with powerpc dynamic relocations. 1) Both ppc and ppc64 were emitting more dynamic symbols and relocations than necessary, due to not supporting static linker resolution of tls_index entries for __tls_get_addr_opt. This meant that any @got@tlsgd or @got@tlsld reloc needed to make their symbols dynamic and generate dptmod and dtprel relocs for the dynamic linker. That would have been passable, but what happened was that practically all @got relocations resulted in their symbols being made dynamic and dynamic relocations emitted against the GOT entries. (Mostly visible on ppc32 executables since ppc64 gcc really only uses @got style relocs for TLS.) 2) The PowerOpen syntax was not supported with __tls_get_addr_opt. DTPMOD/DTPREL relocs on tls_index TOC entries did not use the trick of forcing dynamic symbols and relocations so those entries always resulted in the full __tls_get_addr processing. gcc doesn't use the PowerOpen syntax for TLS, and normally such code would be optimized to TLS IE or LE so the impact of missing this support was minimal. 3) In an executable, relocations against GNU indirect functions always used the value of their PLT stub. While this is correct, it is better in some cases to use a dynamic relocation. An extra dynamic relocation can mean that calls via function pointers need not bounce through the PLT stub at runtime. The patch also tidies the PLT handling code in ppc32 allocate_dynrelocs. Allocating PLT entries after other dynamic relocs allows the PLT loop to omit special handling for undefined weak symbols, and that in turn allows the loop to be simplified. bfd/ * elf32-ppc.c (ppc_elf_adjust_dynamic_symbol): Merge two cases where dynamic relocs are preferable.

Andrew Burgess	1737c64030	objdump: Better objdump section headers in wide mode When displaying the section headers table using objdump (-h), the column containing the section header name is currently fixed at 13 characters. A section name that is longer than 13 characters will overflow the column causing the table to become miss-aligned. In this commit I change the behaviour so that _in wide mode_ (-w -h) the section name column is dynamically resized to fit the longest section name we plan to display. In wide mode the column still retains a minimum width of 13 characters. In non-wide more the behaviour is completely unchanged. While I was changing the dump_headers function I have unified the two printf lines that handled the different address widths into a single printf, the address width is now passed into printf using the '' field width format character. binutils/ChangeLog: objdump.c (dump_section_header): Extract max section name length from data parameter, use this when formatting output.

Maciej W. Rozycki	81ff47b3a5	PR ld/20828: Fix linker script symbols wrongly forced local with section GC Fix a generic ELF linker regression introduced with a chain of changes made to unused input section garbage collection: - commit `1a766c6843` ("Also hide symbols without PLT nor GOT references."), <https://sourceware.org/ml/binutils/2011-09/msg00076.html>, - commit `1d5316ab67` ("PR ld/13177: garbage collector retains zombie references to external libraries"), <https://sourceware.org/ml/binutils/2011-10/msg00161.html>, - commit `6673f753c0` ("Fix PR 12772, garbage collection of dynamic syms"), <https://sourceware.org/ml/binutils/2011-12/msg00077.html>, causing the garbage collection of unused symbols present in a DSO involved in a link to make identically named symbols ordinarily defined (i.e. not hidden or PROVIDEd) by a linker script local, even though the latter symbols are supposed to be global as if no DSO defined them as well. This is because linker script assignments are processed very late as `lang_process' proceeds, down in the call to `ldemul_before_allocation', which is made after the call to `lang_gc_sections' to do input section garbage collecting. Consequently if unused, then any such DSO-defined symbol has already been garbage-collected and internally marked local. It would ordinarily be removed from dynamic symbol table output, however a linker script assignment correctly replaces its original definition with the new one and enters it into the dynamic symbol table produced as it is supposed to be exported. The original local marking is however retained making the symbol local in the dynamic symbol table and therefore not available externally. This also causes a sorting problem with the MIPS target, which does not expect non-section local dynamic symbols to be output and produces an invalid binary. Fix the problem then, by removing the `forced_local' marking for the offending case and add suitable test cases. First to verify that unused symbols ordinarily defined with linker script assignments remain exported in the context of input section garbage collection whether or not a DSO defining identically named symbols is present in the link. Second that a linker version script still correctly retains or removes such symbols as requested. bfd/ PR ld/20828 * elflink.c (bfd_elf_record_link_assignment): Clear any `forced_local' marking for DSO symbols that are not being provided. ld/ PR ld/20828 * testsuite/ld-elf/pr20828-1.sd: New test. * testsuite/ld-elf/pr20828-2a.sd: New test. * testsuite/ld-elf/pr20828-2b.sd: New test. * testsuite/ld-elf/pr20828.ld: New test linker script. * testsuite/ld-elf/pr20828.ver: New test version script. * testsuite/ld-elf/pr20828.s: New test source. * testsuite/ld-elf/shared.exp: Run the new test.	10 years ago
Maciej W. Rozycki	9e009953a5	PR gas/20649: MIPS: Fix GOT16/LO16 reloc pairing with comdat sections Correct a regression from commit `8614eeee67` ("Traditional MIPS patches"), <https://sourceware.org/ml/binutils/2000-07/msg00018.html>, which caused symbols in linkonce or what is these days known as comdat sections to be treated as external for the purpose of PIC relocation generation even if their binding remains STB_LOCAL. This in turn disabled GOT16/LO16 relocation pairing with references to such symbols, as no complementing LO16 relocation is expected for external GOT16 references in the o32 ABI, which ultimately leads to link errors, e.g.: ld: comdat-reloc.o: Can't find matching LO16 reloc against `foo' for R_MIPS_GOT16 at 0x24 in section `.text.bar[bar]' as with the LD test case included with this change. Revert the special case for symbols in comdat sections then, making code actually match `adjust_reloc_syms' as indicated in its explanatory comment, and adjust calling code accordingly. Also bring back the corresponding description of what now is `s_is_linkonce', lost with commit `5f0fe04bc5` ("Improved MIPS16/MIPS32 code intermixing for gas."), <https://www.sourceware.org/ml/binutils/2006-07/msg00039.html>. gas/ PR gas/20649 * config/tc-mips.c (pic_need_relax): Don't check for linkonce symbols, remove the `segtype' parameter.
