Always descend into output section statements in lang_do_assignments See https://sourceware.org/ml/binutils/2016-07/msg00091.html This patch stop --gc-sections elf_gc_sweep_symbol localizing symbols that ought to remain global. The difficulty with always descending into output section statements is that symbols defined by the script in such statements don't have a bfd section when lang_do_assignments runs early in the link process. There are two approaches to curing this problem. Either we can create the bfd section early, or we can use a special section. This patch takes the latter approach and uses bfd_und_section. (Creating bfd sections early results in changed output section order, and thus lots of testsuite failures. You can't create all output sections early to ensure proper ordering as KEEP then stops empty sections from being stripped.) The wrinkle with this approach is that some code that runs at gc-sections time needs to be made aware of the odd defined symbols using bfd_und_section. bfd/ * elf64-x86-64.c (elf_x86_64_convert_load_reloc): Handle symbols defined temporarily with bfd_und_section. * elflink.c (_bfd_elf_gc_keep): Don't set SEC_KEEP for bfd_und_section. * elfxx-mips.c (mips_elf_local_pic_function_p): Exclude defined symbols with bfd_und_section. ld/ * ldlang.c (lang_do_assignments_1): Descend into output section statements that do not yet have bfd sections.

PowerPC .gnu.attributes This patch extends Tag_GNU_Power_ABI_FP to cover long double ABIs, makes the assembler warn about undefined tag values, and removes similar warnings from the linker. I think it is better to not warn in the linker about undefined tag values as future extensions to the tags then won't result in likely bogus warnings. This is consistent with the fact that an older linker won't warn on an entirely new tag. include/ * elf/ppc.h (Tag_GNU_Power_ABI_FP): Comment. bfd/ * elf-bfd.h (_bfd_elf_ppc_merge_fp_attributes): Declare. * elf32-ppc.c (_bfd_elf_ppc_merge_fp_attributes): New function.

[AArch64] Add SVE condition codes SVE defines new names for existing NZCV conditions, to reflect the result of instructions like PTEST. This patch adds support for these names. The patch also adds comments to the disassembly output to show the alternative names of a condition code. For example: cinv x0, x1, cc becomes: cinv x0, x1, cc // cc = lo, ul, last and: b.cc f0 <...> becomes: b.cc f0 <...> // b.lo, b.ul, b.last Doing this for the SVE names follows the practice recommended by the SVE specification and is definitely useful when reading SVE code.

Fix PR ld/20545 - relaxation bugs in avr backend Prior to the patch, addends for relocs were being adjusted even if they went beyond an alignment boundary. This is wrong - to preserve alignment constraints, the relaxation logic adds as many padding bytes at the alignment boundary as was deleted, so addends beyond the boundary should not be adjusted. avr-prop-7.s reproduces this scenario. Also, prior to this patch, the relaxation logic assumed that the addr parameter pointed to the middle of the instruction to be deleted, and that addr - count would therefore be the shrinked instruction's address. This is true when actually shrinking instructions. The alignment constraints handling logic also invokes the same logic though, with addr as the starting offset of padding bytes and with count as the number of bytes to be deleted. Calculating the shrinked insn's address as addr - count is obviously wrong in this case - that offset would point to count bytes before the last non-padded byte. avr-prop-8.s reproduces this scenario. To fix scenario 1, the patch adds an additional check to ensure reloc addends aren't adjusted if they cross a shrink boundary. The shrink boundary is either the section size or an alignment boundary. Addends pointing at an alignment boundary don't need to be adjusted, as padding would occur and keep the boundary the same. Addends pointing at section size need to be adjusted though, as no padding occurs and the section size itself would get decremented. The patch records whether padding occured (did_pad) and uses that to detect and handle this condition. To fix scenario 2, the patch adds an additional parameter (delete_shrinks_insn) to elf32_avr_relax_delete_bytes to distinguish instruction bytes deletion from padding bytes deletion. It then uses that to correctly set shrinked_insn_address. bfd/ChangeLog: 2016-09-02 Senthil Kumar Selvaraj <senthil_kumar.selvaraj@atmel.com> PR ld/20545 * elf32-avr.c (elf32_avr_relax_delete_bytes): Add parameter delete_shrinks_insn.

MIPS/GAS: Implement microMIPS branch/jump compaction Convert microMIPS branches and jumps whose delay slot would be filled by a generated NOP instruction to the corresponding compact form where one exists, in a manner similar to MIPS16 JR->JRC and JALR->JALRC swap. Do so even where the transformation switches from a 16-bit to a 32-bit branch encoding for no benefit in code size reduction, as this is still advantageous. This is because a branch/NOP pair takes 2 pipeline slots or a 2-cycle completion latency except in superscalar implementations. Whereas a compact branch may or may not stall on its target fetch, so it will at most have a 2-cycle completion latency and may have only 1 even in scalar implementations, and in superscalar implementations it is expected to have no worse latency as a branch/NOP pair has. Also it won't stall and therefore take the extra latency cycle in the not-taken case. Technically this is the same as MIPS16 compaction: for the qualifying instruction encodings the APPEND_ADD_COMPACT machine code generation method is selected where APPEND_ADD_WITH_NOP otherwise would and tells the code generator in `append_insn' to convert the regular form of an instruction to its corresponding compact form. For this the opcode is tweaked as necessary and the microMIPS opcode table is scanned for the matching updated instruction. A non-$0 `rt' operand to BEQ and BNE instructions is moved to the `rs' operand field of BEQZC and BNEZC encodings as required. Unlike with MIPS16 compaction however we need to handle out-of-distance branch relaxation as well. We do this by deferring the generation of any delay-slot NOP required to relaxation made in `md_convert_frag', by converting the APPEND_ADD_WITH_NOP machine code generation to APPEND_ADD where a relaxed instruction is recorded. Relaxation then, depending on actual code produced, chooses between either using a compact branch or jump encoding and emitting the NOP outstanding if no compact encoding is possible. For code simplicity's sake the relaxation pass is retained even if the principle of preferring a compact encoding to a 16-bit branch/NOP pair means, in the absence of out-of-range branch relaxation, that a single compact branch machine code instruction will eventually be produced from a given assembly source instruction. gas/ * config/tc-mips.c (RELAX_MICROMIPS_ENCODE): Add `nods' flag.

MIPS: Verify the ISA mode and alignment of branch and jump targets Verify that the ISA mode of branch targets is the same as the referring relocation, so that an attempt to produce a branch between instructions encoded in different ISA modes each causes an error rather than silently producing non-functional code. Make sure that no symbol or addend bits are silently truncated: terminate with an error if the relocation value calculated cannot be encoded in the relocatable field of a branch; for REL targets also applying to any intermediate addend. Also make jump target's alignment verification consistent with that for branches. This change will require an update to some obscure handcoded assembly sources which make branches to labels placed at data objects, however for microMIPS code only. These labels will have to be updated with the `.insn' directive for containing code to assemble and link successfully. Such code is broken as any such labels have always been required by the microMIPS architecture specification[1][2] to be annotated this way for correct interpretation, and with our old code missing `.insn' directives caused labels to present different semantics depending on whether they were referred with branch (ISA bit ignored) or other relocations (ISA bit respected). Enforcing these checks however will ensure errors in building software, like mixed regular MIPS and microMIPS code links with branches between, will be diagnosed at the build time rather than causing odd run-time errors such as intermittent crashes. It will also let cross-mode BAL instructions be converted to JALX instructions, with a separate change.

If these claim methods read content from the input file then the file offset stored in the underlying file descriptor will change. As we share a file descriptor between the plugin interface (created with dup in ld/plugin.c:plugin_object_p) and the input bfd object, then any changes to the file offset in the file descriptor will effect the bfd object. Also, as the changes to the file offset did not originate from calls through the bfd interface, but instead came from the plugin directly, then the bfd will not be aware that the file offset has changed. This is a problem as the bfd library caches the file offset. If the plugin decides not to claim an input file then, currently, we leave the bfd in a state where the actual file offset is out of sync with the cached file offset. This problem came to light after a recent commit 7d0b9ebc1e0079271a7c7737b53bc026525eab64 (Don't include libbfd.h outside of bfd, part 6) however, I don't believe that commit actual introduces the bug, it just exposed the existing issue. This commit solves the problem by backing up and restoring the file offset for the file descriptor of the input file. The restore is only done if the plugin does not claim the input file, as it is in this case that the bfd library might be used again to try and identify the unclaimed file. ld/ChangeLog: * plugin.c (plugin_call_claim_file): Restore the file offset after an unsuccessful attempt to claim a file. * testplug.c (bytes_to_read_before_claim): New global. (record_read_length): New function, sets new global bytes_to_read_before_claim. (parse_option): Handle 'read:<NUMBER>' option.

MIPS/GAS: Don't convert PC-relative REL relocs against absolute symbols Don't convert PC-relative REL relocations against absolute symbols to section-relative references and retain the original symbol reference instead. Offsets into the absolute section may overflow the limited range of their in-place addend field, causing an assembly error, e.g.: $ cat test.s .text .globl foo .ent foo foo: b bar .end foo .set bar, 0x12345678 $ as -EB -32 -o test.o test.s test.s: Assembler messages: test.s:3: Error: relocation overflow $ With the original reference retained the source can now be assembled and linked successfully: $ as -EB -32 -o test.o test.s $ objdump -dr test.o test.o: file format elf32-tradbigmips Disassembly of section .text: 00000000 <foo>: 0: 1000ffff b 0 <foo> 0: R_MIPS_PC16 bar 4: 00000000 nop ... $ ld -melf32btsmip -Ttext 0x12340000 -e foo -o test test.o $ objdump -dr test test: file format elf32-tradbigmips Disassembly of section .text: 12340000 <foo>: 12340000: 1000159d b 12345678 <bar> 12340004: 00000000 nop ... $ For simplicity always retain the original symbol reference, even if it would indeed fit. Making TC_FORCE_RELOCATION_ABS separate from TC_FORCE_RELOCATION causes R_MICROMIPS_PC7_S1, R_MICROMIPS_PC10_S1 and R_MICROMIPS_PC16_S1 branch relocations against absolute symbols to be converted on RELA targets to section-relative references. This is an intended effect of this change. Absolute symbols carry no ISA annotation in their `st_other' field and their value is not going to change with linker relaxation, so it is safe to discard the original reference and keep the calculated final symbol value only in the relocation's addend. Similarly R6 R_MIPS_PCHI16 and R_MIPS_PCLO16 relocations referring absolute symbols can be safely converted even on REL targets, as there the in-place addend of these relocations covers the entire 32-bit address space so it can hold the calculated final symbol value, and likewise the value referred won't be affected by any linker relaxation. Add a set of suitable test cases and enable REL linker tests which now work and were previously used as dump patterns for RELA tests only. gas/ * config/tc-mips.h (TC_FORCE_RELOCATION_ABS): New macro.

MIPS/GAS: Keep the ISA bit in the addend of branch relocations Correct a problem with the ISA bit being stripped from the addend of compressed branch relocations, affecting RELA targets. It has been there since microMIPS support has been added, with: commit df58fc944dbc6d5efd8d3826241b64b6af22f447 Author: Richard Sandiford <rdsandiford@googlemail.com> Date: Sun Jul 24 14:20:15 2011 +0000 <https://sourceware.org/ml/binutils/2011-07/msg00198.html>, ("MIPS: microMIPS ASE support") and R_MICROMIPS_PC7_S1, R_MICROMIPS_PC10_S1 and R_MICROMIPS_PC16_S1 relocations originally affected, and the R_MIPS16_PC16_S1 relocation recently added with commit c9775dde3277 ("MIPS16: Add R_MIPS16_PC16_S1 branch relocation support") actually triggering a linker error, due to its heightened processing strictness level: $ cat test.s .text .set mips16 foo: b bar .set bar, 0x1235 .align 4, 0 $ as -EB -n32 -o test.o test.s $ objdump -dr test.o test.o: file format elf32-ntradbigmips Disassembly of section .text: 00000000 <foo>: 0: f000 1000 b 4 <foo+0x4> 0: R_MIPS16_PC16_S1 *ABS*+0x1230 ... $ ld -melf32btsmipn32 -Ttext 0 -e 0 -o test test.o test.o: In function `foo': (.text+0x0): Branch to a non-instruction-aligned address $ This is because the ISA bit of the branch target does not match the ISA bit of the referring branch, hardwired to 1 of course.

BFD: Let targets handle relocations against absolute symbols Fix a generic BFD issue with relocations against absolute symbols, which are installed without using any individual relocation handler provided by the backend. This causes any absolute section's addend to be lost on REL targets such as o32 MIPS, and also relocation-specific calculation adjustments are not made. As an example assembling this program: $ cat test.s .text foo: b bar b baz .set bar, 0x1234 $ as -EB -32 -o test-o32.o test.s $ as -EB -n32 -o test-n32.o test.s produces this binary code: $ objdump -dr test-o32.o test-n32.o test-o32.o: file format elf32-tradbigmips Disassembly of section .text: 00000000 <foo>: 0: 10000000 b 4 <foo+0x4> 0: R_MIPS_PC16 *ABS* 4: 00000000 nop 8: 1000ffff b 8 <foo+0x8> 8: R_MIPS_PC16 baz c: 00000000 nop test-n32.o: file format elf32-ntradbigmips Disassembly of section .text: 00000000 <foo>: 0: 10000000 b 4 <foo+0x4> 0: R_MIPS_PC16 *ABS*+0x1230 4: 00000000 nop 8: 10000000 b c <foo+0xc> 8: R_MIPS_PC16 baz-0x4 c: 00000000 nop $ where it is clearly visible in `test-o32.o', which uses REL relocations, that the absolute section's addend equivalent to the value of `bar' -- a reference to which cannot be fully resolved at the assembly time, because the reference is PC-relative -- has been lost, as has been the relocation-specific adjustment of -4, required to take into account the PC+4-relative calculation made by hardware with branches and seen in the external symbol reference to `baz' as the `ffff' addend encoded in the instruction word. In `test-n32.o', which uses RELA relocations, the absolute section's addend has been correctly retained. Give precedence then in `bfd_perform_relocation' and `bfd_install_relocation' to any individual relocation handler the backend selected may have provided, while still resorting to the generic calculation otherwise. This retains the semantics which we've had since forever or before the beginning of our repository history, and is at the very least compatible with `bfd_elf_generic_reloc' being used as the handler. Retain the `bfd_is_und_section' check unchanged at the beginning of `bfd_perform_relocation' since this does not affect the semantics of the function. The check returns the same `bfd_reloc_undefined' code the check for a null `howto' does, so swapping the two does not matter. Also the check is is mutually exclusive with the `bfd_is_abs_section' check, since a section cannot be absolute and undefined both at once, so swapping the two does not matter either. With this change applied the program quoted above now has the in-place addend correctly calculated and installed in the field being relocated: $ objdump -dr fixed-o32.o fixed-o32.o: file format elf32-tradbigmips Disassembly of section .text: 00000000 <foo>: 0: 1000048c b 1234 <bar> 0: R_MIPS_PC16 *ABS* 4: 00000000 nop 8: 1000ffff b 8 <foo+0x8> 8: R_MIPS_PC16 baz c: 00000000 nop $ Add a set of MIPS tests to cover the relevant cases, including absolute symbols with addends, and verifying that PC-relative relocations against symbols concerned resolve to the same value in the final link regardless of whether the REL or the RELA relocation form is used. Exclude linker tests though which would overflow the in-place addend on REL targets and use them as dump patterns for RELA targets only. bfd/ * reloc.c (bfd_perform_relocation): Try the `howto' handler first with relocations against absolute symbols.

Support i386 TLS code sequences without PLT We can generate i386 TLS code sequences for general and local dynamic models without PLT, which uses indirect call via GOT: call *___tls_get_addr@GOT(%reg) where EBX register isn't required as GOT base, instead of direct call: call ___tls_get_addr[@PLT] which requires EBX register as GOT base. Since direct call is 4-byte long and indirect call, is 5-byte long, the extra one byte must be handled properly. For general dynamic model, 7-byte lea instruction before call instruction is replaced by 6-byte one to make room for indirect call. For local dynamic model, we simply use 5-byte indirect call. TLS linker optimization is updated to recognize new instruction patterns. For local dynamic model to local exec model transition, we generate a 6-byte lea instruction as nop, instead of a 1-byte nop plus a 4-byte lea instruction. Since linker may convert call ___tls_get_addr[@PLT] to addr32 call ____tls_get_addr when producing static executable, both patterns are recognized. bfd/ * elf64-i386.c (elf_i386_link_hash_entry): Add tls_get_addr.

PowerPC VLE VLE is an encoding, not a particular processor architecture, so it isn't really proper to select insns based on PPC_OPCODE_VLE. For example {"evaddw", VX (4, 512), VX_MASK, PPCSPE|PPCVLE, PPCNONE, {RS, RA, RB}}, {"vaddubs", VX (4, 512), VX_MASK, PPCVEC|PPCVLE, PPCNONE, {VD, VA, VB}}, shows two insns that have the same encoding, both available with VLE. Enabling both with VLE means we can't disassemble the second variant even if -Maltivec is given rather than -Mspe. Also, we don't check user assembly against the processor type as well as we could. Another problem is that when using the VLE encoding, insns from the main ppc opcode table are not available, except those using opcode 4 and 31. Correcting this revealed two errors in the ld testsuite, use of "nop" and "rfmci" when -mvle. This patch fixes those problems in the opcode table, and removes PPCNONE. I find a plain 0 distracts less from other values. In addition, I've implemented code to recognize some machine values from the apuinfo note present in ppc32 objects. It's not a complete disambiguation since we're lacking info to detect newer chips, but what we have should help with disassembly. include/ * elf/ppc.h (APUINFO_SECTION_NAME, APUINFO_LABEL, PPC_APUINFO_ISEL, PPC_APUINFO_PMR, PPC_APUINFO_RFMCI, PPC_APUINFO_CACHELCK, PPC_APUINFO_SPE, PPC_APUINFO_EFS, PPC_APUINFO_BRLOCK, PPC_APUINFO_VLE: Define. opcodes/ * ppc-dis.c (ppc_opts): Delete extraneous parentheses.

Support x86-64 TLS code sequences without PLT We can generate x86-64 TLS code sequences for general and local dynamic models without PLT, which uses indirect call via GOT: call *__tls_get_addr@GOTPCREL(%rip) instead of direct call: call __tls_get_addr[@PLT] Since direct call is 4-byte long and indirect call, is 5-byte long, the extra one byte must be handled properly. For general dynamic model, one 0x66 prefix before call instruction is removed to make room for indirect call. For local dynamic model, we simply use 5-byte indirect call. TLS linker optimization is updated to recognize new instruction patterns. For local dynamic model to local exec model transition, we generate 4 0x66 prefixes, instead of 3, before mov instruction in 64-bit and generate a 5-byte nop, instead of 4-byte, before mov instruction in 32-bit. Since linker may convert call *__tls_get_addr@GOTPCREL(%rip) to addr32 call __tls_get_addr when producing static executable, both patterns are recognized. bfd/ * elf64-x86-64.c (elf_x86_64_link_hash_entry): Add tls_get_addr.

MIPS/BFD: Enable local R_MIPS_26 overflow detection The original MIPS SVR4 psABI defines the calculation for the R_MIPS_26 relocation in a complex way, as follows[1]: Name Value Field Symbol Calculation R_MIPS_26 4 T-targ26 local (((A << 2) | \ (P & 0xf0000000)) + S) >> 2 4 T-targ26 external (sign-extend(A << 2) + S) >> 2 This is further clarified, by correcting typos (already applied in the excerpt above) in the 64-bit psABI extension[2]. A note is included in both documents to specify that for the purpose of relocation processing a local symbol is one with binding STB_LOCAL and type STT_SECTION, and otherwise, a symbol is external. We have both calculations implemented for the R_MIPS_26 relocation, and by extension also for the R_MIPS16_26 and R_MICROMIPS_26_S1 relocations, from now on collectively called jump relocations. However our code uses a different condition to tell local and external symbols apart, that is it only checks for the STB_LOCAL binding and ignores the symbol type, however for REL relocations only. The external calculation is used for all RELA jump relocations. In reality the difference matters for jump relocations referring local MIPS16 and, as from recent commit 44d3da233815 ("MIPS/GAS: Treat local jump relocs the same no matter if REL or RELA"), also local microMIPS symbols. Such relocations are not converted to refer to corresponding section symbols instead and retain the original local symbol reference. It can be inferred from the relocation calculation definitions that the addend is effectively unsigned for the local case and explicitly signed for the external case. With the REL relocation format it makes sense given the limited range provided for by the field being relocated: the use of an unsigned addend expands the range by one bit for the local case, because a negative offset from a section symbol makes no sense, and any usable negative offset from the original local symbol will have worked out positive if converted to a section-relative reference. In the external case a signed addend gives more flexibility as offsets both negative and positive can be used with a symbol. Any such offsets will typically have a small value. The inclusion of the (P & 0xf0000000) component, ORed in the calculation in the local case, seems questionable as bits 31:28 are not included in the relocatable field and are masked out as the relocation is applied. Their value is therefore irrelevant for output processing, the relocated field ends up the same regardless of their value. They could be used for overflow detection, however this is precluded by adding them to bits 31:28 of the symbol referred, as the sum will not correspond to the value calculated by the processor at run time whenever bits 31:28 of the symbol referred are not all zeros, even though it is valid as long they are the same as bits 31:28 of P. We deal with this problem by ignoring any overflow resulting from the local calculation. This however makes us miss genuine overflow cases, where 31:28 of the symbol referred are different from bits 31:28 of P, and non-functional code is produced. Given the situation, for the purpose of overflow detection we can change our code to follow the original psABI and only treat the in-place addend as unsigned in the section symbol case, permitting jumps to offsets 128MiB and above into section. Sections so large may be uncommon, but still a reasonable use case. On the other hand such large offsets from regular local symbols are not expected and it makes sense to support (possibly small) negative offsets instead, also in consistency with what we do for global symbols. Drop the (P & 0xf0000000) component then, treat the addend as signed with local non-section symbols and also detect an overflow in the result of such calculation with local symbols. NB it does not affect the value computed for the relocatable field, it only affects overflow detection.

Return void from linker callbacks The ldmain.c implementation of these linker callback functions always return true, so any code handling a false return is dead. What's more, some of the bfd backends abort if ever a false return is seen, and there seems to be some confusion in gdb's compile-object-load.c. The return value was never meant to be "oh yes, a multiple_definition error occurred", but rather "out of memory or other catastrophic failure". This patch removes the status return on the callbacks that always return true. I kept the return status for "notice" because that one does happen to need to return "out of memory". include/ * bfdlink.h (struct bfd_link_callbacks): Update comments.

MIPS/BFD: Fix section symbol name fetching in relocation Symbol table entries for section symbols are different between IRIX and traditional MIPS ELF targets in that IRIX entries have their `st_name' member pointing at the section's name in the string table section, while traditional entries have 0 there and the section header string table has to be referred via the relevant section header's `shn_name' member instead. This is chosen with the `elf_backend_name_local_section_symbols' backend and can be observed with `readelf -s' output for an IRIX object: Symbol table '.symtab' contains 12 entries: Num: Value Size Type Bind Vis Ndx Name 0: 00000000 0 NOTYPE LOCAL DEFAULT UND 1: 00000000 0 SECTION LOCAL DEFAULT 1 .text 2: 00000000 0 SECTION LOCAL DEFAULT 3 .data 3: 00000000 0 SECTION LOCAL DEFAULT 4 .bss 4: 00000000 0 SECTION LOCAL DEFAULT 5 .reginfo 5: 00000000 0 SECTION LOCAL DEFAULT 6 .MIPS.abiflags 6: 00000000 0 SECTION LOCAL DEFAULT 7 .pdr 7: 00000000 0 SECTION LOCAL DEFAULT 9 .gnu.attributes 8: 00002000 16 FUNC GLOBAL DEFAULT 1 foo 9: 00004008 0 FUNC LOCAL DEFAULT 1 abar 10: 00002008 0 FUNC LOCAL DEFAULT 1 afoo 11: 00004000 16 FUNC GLOBAL DEFAULT 1 bar and a corresponding traditional object: Symbol table '.symtab' contains 12 entries: Num: Value Size Type Bind Vis Ndx Name 0: 00000000 0 NOTYPE LOCAL DEFAULT UND 1: 00000000 0 SECTION LOCAL DEFAULT 1 2: 00000000 0 SECTION LOCAL DEFAULT 3 3: 00000000 0 SECTION LOCAL DEFAULT 4 4: 00004008 0 FUNC LOCAL DEFAULT 1 abar 5: 00002008 0 FUNC LOCAL DEFAULT 1 afoo 6: 00000000 0 SECTION LOCAL DEFAULT 5 7: 00000000 0 SECTION LOCAL DEFAULT 6 8: 00000000 0 SECTION LOCAL DEFAULT 7 9: 00000000 0 SECTION LOCAL DEFAULT 9 10: 00002000 16 FUNC GLOBAL DEFAULT 1 foo 11: 00004000 16 FUNC GLOBAL DEFAULT 1 bar respectively. Consequently the right way to retrieve a section symbol's name has to be chosen in `mips_elf_calculate_relocation' for the purpose of error reporting. Originally we produced symbol tables in the traditional object format only and we handled it correctly until it was lost in a rewrite with: commit 7403cb6305f5660fccc8869d3333a731102ae978 Author: Mark Mitchell <mark@codesourcery.com> Date: Wed Jun 30 20:13:43 1999 +0000 probably because of the extra pointer indirection added which made the same expression have a different meaning. With the addition of IRIX symbol table format with: commit 174fd7f9556183397625dbfa99ef68ecd325c74b Author: Richard Sandiford <rdsandiford@googlemail.com> Date: Mon Feb 9 08:04:00 2004 +0000 the bug has been partially covered and now when a relocation error is triggered with an IRIX object the offending section symbol is correctly reported: tmpdir/dump0.o: In function `foo': (.text+0x2000): relocation truncated to fit: R_MIPS_26 against `.text' tmpdir/dump0.o: In function `bar': (.text+0x4000): relocation truncated to fit: R_MIPS_26 against `.text' because `bfd_elf_string_from_elf_section' retrieves the name from the string table section. With a traditional object however the function returns an empty string and consequently `no symbol' is printed instead: tmpdir/dump0.o: In function `foo': (.text+0x2000): relocation truncated to fit: R_MIPS_26 against `no symbol' tmpdir/dump0.o: In function `bar': (.text+0x4000): relocation truncated to fit: R_MIPS_26 against `no symbol' Restore the original semantics so that the section name is always correctly retrieved. bfd/ * elfxx-mips.c (mips_elf_calculate_relocation): Also use the section name if `bfd_elf_string_from_elf_section' returns an empty string. ld/ * testsuite/ld-mips-elf/reloc-local-overflow.d: New test. * testsuite/ld-mips-elf/reloc-local-overflow.s: Source for the new test. * testsuite/ld-mips-elf/mips-elf.exp: Run the new test.

MIPS: Fix the encoding of immediates with microMIPS JALX The microMIPS JALX instruction shares the R_MICROMIPS_26_S1 relocation with microMIPS J/JAL/JALS instructions, however unlike the latters its encoded immediate argument is unusually shifted left by 2 rather than 1 in calculating the value used for the operation requested. We already handle this exception in `mips_elf_calculate_relocation' in LD, in a scenario where JALX is produced as a result of relaxing JAL for the purpose of making a cross-mode jump. We also get it right in the disassembler in `decode_micromips_operand'. What we don't correctly do however is processing microMIPS JALX produced by GAS from an assembly source, where a non-zero constant argument or a symbol reference with a non-zero in-place addend has been used. In this case the same calculation is made as for microMIPS J/JAL/JALS, causing the wrong encoding to be produced by GAS on making an object file, and then again by LD in the final link. The latter in particular causes the calculation, where the addend fits in the relocatable field, to produce different final addresses for the same source code depending on whether REL or RELA relocations are used. Correct these issues by special-casing microMIPS JALX in the places that have been previously missed. bfd/ * elfxx-mips.c (mips_elf_read_rel_addend): Adjust the addend for microMIPS JALX. gas/ * config/tc-mips.c (append_insn): Correct the encoding of a constant argument for microMIPS JALX.

ld/arc: Fix linker for big-endian arc targets This aims to bring the linker for big-endian arc targets into line with the linker for (the default) little endian arc targets. The bulk of the changes are to extend the target pattern in the test files from 'arc-*...' to 'arc*-*...' and so match both big and little endian arc targets. In the ld/emulparams/ directory the existing scripts checked for a variable ARC_ENDIAN to switch between big and little endian targets, however, this variable is never set up. So, a new script snippet is introduced which sets up ARC_ENDIAN based on the value of target, this snippet is then included from all of the existing arc scripts. The existing big-endian variants of all the scripts, which existed, but were never used, are deleted in this commit. ld/ChangeLog: * emulparams/arc-endianness.sh: New file. * emulparams/arcebelf.sh: Deleted. * emulparams/arcebelf_prof.sh: Deleted. * emulparams/arceblinux.sh: Deleted. * emulparams/arceblinux_prof.sh: Deleted. * emulparams/arcelf.sh: Include arc-endinness.sh. * emulparams/arcelf_prof.sh: Include arc-endinness.sh. * emulparams/arclinux.sh: Include arc-endinness.sh. * emulparams/arclinux_prof.sh: Include arc-endinness.sh. * emulparams/arcv2elf.sh: Include arc-endinness.sh. * emulparams/arcv2elfx.sh: Include arc-endinness.sh. * testsuite/ld-elf/compressed1d.d: Update pattern for big and little endian arc targets. * testsuite/ld-elf/eh-frame-hdr.d: Likewise. * testsuite/ld-elf/group1.d: Likewise. * testsuite/ld-elf/group3b.d: Likewise. * testsuite/ld-elf/group8a.d: Likewise. * testsuite/ld-elf/group8b.d: Likewise. * testsuite/ld-elf/group9a.d: Likewise. * testsuite/ld-elf/group9b.d: Likewise. * testsuite/ld-elf/linkonce2.d: Likewise. * testsuite/ld-elf/pr12851.d: Likewise. * testsuite/ld-elf/pr12975.d: Likewise. * testsuite/ld-elf/pr13177.d: Likewise. * testsuite/ld-elf/pr13195.d: Likewise. * testsuite/ld-elf/pr17615.d: Likewise. * testsuite/ld-elf/pr19162.d: Likewise. * testsuite/ld-elf/sec64k.exp: Likewise. * testsuite/lib/ld-lib.exp: Likewise.

ELF/LD: Avoid producing hidden and internal dynamic symbols Always turn hidden and internal symbols which have a dynamic index into local ones. This is required by the the ELF gABI[1]: "A hidden symbol contained in a relocatable object must be either removed or converted to STB_LOCAL binding by the link-editor when the relocatable object is included in an executable file or shared object." "An internal symbol contained in a relocatable object must be either removed or converted to STB_LOCAL binding by the link-editor when the relocatable object is included in an executable file or shared object." The ELF linker usually respects this requirement, however in the case where a dynamic symbol has been preallocated due to a reference of the default export class aka visibility from the object being linked, and then merged with a hidden or internal symbol definition from within the same object, then the original export class is carried over to the output dynamic symbol table, because while merging the generic ELF linker only converts affected dynamic symbols to local when they are defined or referenced by the object being linked and a dynamic object involved in the link both at a time. The dynamic symbol produced confuses then the dynamic loader at the run time -- the hidden or internal export class is ignored and the symbol follows preemption rules as with the default export class. In the MIPS target it happens when `mips_elf_record_global_got_symbol' creates a dynamic symbol when a call relocation is encountered. Additionally if the undefined symbol referred by such a relocation does specify the intended export class, then a local dynamic symbol is created instead, which is harmless and allowed, but useless. Normally no local dynamic symbols are created, except for a single dummy one at the beginning. Correct the problem by removing the extra check for a dynamic symbol being defined or referenced by the object being linked and a dynamic object involved in the link both at a time. The test cases included cover the internal and hidden symbol cases, as well as a protected symbol for a reference, the handling of which is unchanged by this fix. Both cases described above are covered, that is where an internal or hidden dynamic symbol is produced and where a local one is. NB this change affects CRIS results where some symbols in the static table produced in a final link are now converted from STV_HIDDEN to STB_LOCAL. This happens whenever the `elf_backend_hide_symbol' handler is called, so the affected symbols must have been chosen for entering into the dynamic symbol table, except in these test cases no such symbol table is produced. In fully linked binaries the static symbol table is only used for debugging though, so such a change is fine.

Fix v850 bfd arch info printable names Currently, it's not possible to manually set some of the v850 archs in gdb: (gdb) set architecture v850<TAB> v850 (using old gcc ABI) v850-rh850 v850e v850e (using old gcc ABI) v850e1 [...] (gdb) set architecture v850 (using old gcc ABI) Ambiguous item "v850 (using old gcc ABI)". The problem is that "set architecture" is a GDB "enum command", and GDB only considers an enum value to be the string up until the first space. So writing "v850 (using old gcc ABI)" is the same as writing "v850", and then that's not an unambiguous arch printable name prefix. v850 is actually the only arch that has spaces in its printable name. One can conveniently see that with e.g.: (gdb) set max-completions unlimited (gdb) complete set architecture ... Rather than hack GDB into accepting this somehow, make v850 arch printable names more like the printable names of the other archs, and put the abi variant in the "machine" part, after a ':'. We now get: (gdb) set architecture v850<TAB> v850:old-gcc-abi v850:rh850 v850e v850e1 v850e1:old-gcc-abi v850e2 v850e2:old-gcc-abi [...] And now "set architecture v850:old-gcc-abi" works as expected. I ran the binutils/gas/ld testsuites, and found no regressions. I don't have a cross compiler handy, but I ran the gdb tests anyway, which covers at least some snoke testing. I think that the OUTPUT_ARCH in ld/scripttempl/v850.sc may have got broken with the previous 2012 change, since I hacked v850_rh850.sc to output "v850" and ld failed to grok it. I think it only works if the old GCC ABI is the configured v850 default ABI. That's now fixed by changing to use explicit v850:old-gcc-abi. Also, this actually "fixes" an existing GDB test, which isn't likewise expecting spaces in arch names, when GDB is configured for --target=v850: (gdb) FAIL: gdb.xml/tdesc-arch.exp: read valid architectures bfd/ChangeLog: 2016-03-09 Pedro Alves <palves@redhat.com> * cpu-v850.c (N): Append ":old-gcc-abi" instead of " (using old gcc ABI)" to printable name. * cpu-v850_rh850.c (bfd_v850_rh850_arch): Use "v850:rh850" instead of "v850-rh850" as printable name. ld/ChangeLog: 2016-03-09 Pedro Alves <palves@redhat.com> * scripttempl/v850.sc: Use "v850:old-gcc-abi" as OUTPUT_ARCH. * scripttempl/v850_rh850.sc: Use "v850:rh850" as OUTPUT_ARCH.

Optimize x86 GOT32X/GOTPCRELX relocations R_386_GOT32X, R_X86_64_GOTPCRELX and R_X86_64_REX_GOTPCRELX relocations retrieve the symbol address via its GOT slot. If the symbol address is known at the link-time, we can use it directly by changing instruction encoding. Indirect branch can only be converted to PC relative direct branch. MOV can be changed to LEA or encoded differently with signed address. The subset of binary operations can be encoded only with signed address. If undefined weak symbol is resolved to zero link-time, we can use it as address. Zero addresss can't used with PC relative direct branch when PIC is true since the current PC is unknown. In 64-bit, 32-bit relocation for PC relatiave direct branch to zero may also overflow. If this optimization causes relocation overflow, --no-relax can be used to work around it. bfd/ PR ld/19609 * elf32-i386.c (elf_i386_convert_load): Convert to R_386_32 for load with locally bound symbols if PIC is false or there is no base register.

[x86] Resolve non-PIC undefweak symbols in executable For i386 and x86-64, non-PIC references to undefined weak symbols are resolved without dynamic relocation when creating executable. Resolved undefined weak symbols are removed from the dynamic symbol table in executable. One exception is on i386, we need resolved undefined weak symbols in the dynamic symbol table in PIE if input relocatable files contain branchs without PLT so that we can branch to 0 with dynamic relocation in text section. This makes behaviors of dynamic executable and position independent executable predictable with mixed PIC and non-PIC references to undefined weak symbols. If all references to undefined weak symbols are PIC, dynamic relocations against undefined weak symbols will be generated in executable unless -z nodynamic-undefined-weak is passed to linker. bfd/ PR ld/19636 PR ld/19704 PR ld/19719 * elf32-i386.c (UNDEFINED_WEAK_RESOLVED_TO_ZERO): New.

Add -mrelax-relocations= to x86 assembler The x86 relax relocations introduced in binutils 2.26 aren't supported by linker on Solaris older than Solaris 12. To use x86 assembler with older Solaris linker, this patch adds 1. A command line option -mrelax-relocations= to x86 assembler to control whether to generate relax relocations. 2. A configure option --enable-x86-relax-relocations to decide whether x86 assembler should generate relax relocations by default. It is defaulted to yes, except for x86 Solaris targets older than Solaris 12. gas/ PR gas/19520 * NEWS: Mention new command line option -mrelax-relocations and new configure option --enable-x86-relax-relocations for x86 target. * config.in: Regenerated. * configure.ac: Add --enable-x86-relax-relocations.

MIPS/BFD: Move attribute check after ELF file header flag check We have a problem in that in making compatibility checks while merging private BFD data on the MIPS target we give priority to the attribute check, which may fail and cause the function to abort early on. The problem with this is the ABI compatibility aspect recorded in the attributes is relatively minor compared to aspects recorded in the ELF file header. However the premature exit causes any more important compatibility aspect violated to be masked and not reported to the user once a problem with attributes has been noticed. So move the attribute check after the ELF file header flag check in `_bfd_mips_elf_merge_private_bfd_data', and do not return prematurely there. Take advantage of the resulting grouping of ELF file header handling together and remove the premature success return point for the first input object being handled, letting the code later on figure out output ABI flags even for this object. Update LD test cases according to messages from ELF file header checks now preceding ones from attribute checks. bfd/ * elfxx-mips.c (_bfd_mips_elf_merge_private_bfd_data): Move attribute check after ELF file header flag check. ld/ * testsuite/ld-mips-elf/attr-gnu-4-14.d: Update the order of messages expected according to MIPS BFD private data merge changes. * testsuite/ld-mips-elf/attr-gnu-4-24.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-34.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-41.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-42.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-43.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-45.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-46.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-47.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-48.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-49.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-54.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-64.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-74.d: Likewise.
