bfd,opcodes: sparc: new opcode v9{c,d,e,v,m} architectures and bfd machine numbers. This patch adds support for the opcode architectures SPARC_OPCODE_ARCH_V9{C,D,E,V,M} and its associated BFD machine numbers bfd_mach_sparc_v9{c,d,e,v,m} and bfd_mach_sparc_v8plus{c,d,e,v,m}. Note that for arches up to v9b (UltraSPARC III), the detection of the BFD machine type was based on the bits in the e_machine field of the ELF header. However, there are no more available bits in that field, so this patch takes the approach of using the hardware capabilities stored in the object attributes HWCAPS/HWCAPS2 in order to characterize the machine the object was built for. bfd/ChangeLog: 2016-06-17 Jose E.

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.

(_bfd_mips_elf_relocate_section) <bfd_reloc_outofrange>: Handle
branch relocations.
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.

Enable 64-bit archives in ar and ranlib Since existing ld and gold support the 64-bit (MIPS) ELF archives, we can use the 64-bit (MIPS) ELF archives as 64-bit archives. Since the plugin target is used to create archive in plugin-enabled ar, we need a way to enable 64-bit archives in the plugin target. This patch adds --enable-64-bit-archive to bfd to force 64-bit archives in ar and ranlib. Since both 64-bit MIPS and s390 ELF targets currently use 64-bit archives, 64-bit archives are enabled by default for them. 64-bit archive is generated automatically if the archive is too big. Tested on Linux/x86 and Linux/x86-64 with existing ld and gold. bfd/ PR binutils/14625 * archive.c (bfd_slurp_armap): Replace bfd_elf64_archive_slurp_armap with _bfd_archive_64_bit_slurp_armap.

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.

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.

arc: Remove EF_ARC_CPU_GENERIC constant. The constant EF_ARC_CPU_GENERIC is defined in the include/elf/arc.h file, and is used in a few places in binutils, however, this constant should never make it into the elf header flags; we always set a valid cpu type in the assembler, which should then be copied over during linking. There are some non-gnu arc compilers that don't write an architecture type into the e_flags field, instead leaving the field as 0, which is the EF_ARC_CPU_GENERIC value. This non-gnu compiler uses the machine type to distinguish between the old and newer arc architectures, setting the machine type to EM_ARC_COMPACT for old arc600, arc601, and arc700 architectures, while using EM_ARC_COMPACT2 for newer arcem and archs architectures. Previously when displaying the machine flags for an older EM_ARC_COMPACT machine, if the e_flags had not been filled in, then we relied on the default case statement to display the message "Generic ARCompact", while in the EM_ARC_COMPACT2 case we specifically handled EF_ARC_CPU_GENERIC to print "ARC Generic", leaving the default case to print a message about unrecognised cpu flag. After this commit EF_ARC_CPU_GENERIC has been removed, for both machine types EM_ARC_COMPACT and EM_ARC_COMPACT2 we now rely on the default case statement to handle the situation where the e_flags has not been filled in. The message displayed is now "Unknown ARCompact" (for older arc architectures) and "Unknown ARC" (for the newer architectures). The switch from "Generic" to "Unknown" in the message string is for clarity, calling the file "Generic" can give the impression that the file is compiled for a common sub-set of the architectures, and would therefore run on any type of machine (or at least any type of new or old machine depending on if the machine type is ARC or ARCv2). However, this was not what "Generic" meant, it really meant "Unknown", so that's what we now say. As part of the merging of the readelf flag reading code, I have unified the strings used in displaying the ELF ABI. This means that for older arc machines (arc600, arc601, and arc700) the string used for the original ABI, and ABIv2 have changed, the current ABIv3 remains the same. For the newer architectures (arcem and archs) the abi strings remain unchanged in all cases. bfd/ChangeLog: * elf32-arc.c (arc_elf_print_private_bfd_data): Remove use of EF_ARC_CPU_GENERIC.

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.

[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.

Fix BFD format matching for x86_64-w64-mingw32 -m32 LTO. In <https://sourceware.org/ml/binutils/2015-12/msg00190.html> (commit 4a07dc81356ed8728e204e9aabeb256703c59aef), Kwok fixed a problem with the template used for a dummy BFD for an IR file for LTO on MinGW, where the input and output formats are not the same. A problem, however, remains in the case of linking for x86_64-w64-mingw32 -m32, where LTO linking reports an ambiguity between the pe-i386 and pei-i386 formats. An object (pe-i386) with plugin data is being tested by the linker to see what formats match. The default format initially set by the linker when bfd_check_format_matches is called is pei-i386 (as that's the output format from the linker script), which does not match, so the function goes on to the loop over possible BFD vectors. The pe-i386 vector matches, as it should. One other vector matches: the plugin vector. bfd_check_format_matches tests a vector for matching by temporarily modifying the BFD object to use that vector then using _bfd_check_format on it. So the BFD object is temporarily using plugin_vec. _bfd_check_format ends up using bfd_plugin_object_p which uses plugin_object_p from ld which uses plugin_get_ir_dummy_bfd which succeeds, having created a BFD based on link_info.output_bfd (because srctemplate is the BFD temporarily using plugin_vec, even after Kwok's patch link_info.output_bfd is all that's available to base the dummy BFD on). So we end up with a match from the plugin vector which uses the pei-i386 vector even though the pei-i386 vector itself does not match the input object. (In the i686-mingw32 case, as opposed to this multilib case, pe-i386 is the default BFD target, which would short-circuit that logic.) There are two cases of the linker handling inputs with a plugin: they may be inputs that are also accepted by some non-plugin BFD format, as here, or they may be a format that would not be recognized at all, as with some tests in the ld testsuite. In the former case, there is no need for BFD to accept the objects using the plugin vector, as the linker has its own logic to allow plugins to claim objects accepted by some other BFD vector. Thus, this patch arranges for the plugin vector to have the lowest match priority, and for the priority from that vector to be used in the relevant case (the attempted match to the plugin vector results in TEMP pointing to the pei-i386 vector). Tested for GCC and Binutils testsuites for x86_64-pc-linux-gnu, as well as verifying that it fixes the observed LTO issue for x86_64-w64-mingw32. * plugin.c (plugin_vec): Set match priority to 255. * format.c (bfd_check_format_matches) [BFD_SUPPORTS_PLUGINS]: When matching against the plugin vector, take priority from there not from TEMP.

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.
