2019-09-06beos.em qsort predicate tidyAlan Modra1-29/+24

This macro says: /* Cast from const char * to char * so that caller can assign to a char * without a warning. */ I reckon that isn't such a good idea since it can result in char* variables where const char* is appropriate.

2019-08-10lang_input_statement_type next pointersAlan Modra2-6/+5
"next" and "next_real_file" in lang_input_statement_type always point to another lang_input_statement_type, so it makes sense for these to not be the generic lang_statement_union_type.

2019-08-09Add support for a MIPS specific .MIPS.xhash section.Mihailo Stojanovic1-16/+0
This patch is a reimplementation of [1] which was submitted in 2015 by Neil Schellenberger. Copyright issue was sorted out [2] last year. It proposed a new section (.gnu.xhash) and related dynamic tag (DT_GNU_XHASH). The new section would be virtually identical to the existing .gnu.hash except for the translation table (xlat) which would contain correct MIPS .dynsym indexes corresponding to the hashvals in chains. This is because MIPS ABI imposes a different ordering on the dynsyms than the one expected by the .gnu.hash section. Another addition would be a leading word (ngnusyms) which would contain the number of entries in the translation table. In this patch, the new section name and dynamic tag are changed to reflect the fact that the section should be treated as MIPS-specific (.MIPS.xhash and DT_MIPS_XHASH). This patch addresses the alignment issue as reported in [3], which is caused by the leading word added to the .MIPS.xhash section. Leading word is removed in this patch, and the number of entries in the translation table is now calculated using DT_MIPS_SYMTABNO dynamic tag (this is addressed by the corresponding glibc patch). Suggestions on coding style in [4] were taken into account. Existing GNU hash testcase was covered, and another one was added in the MIPS part of the testsuite. The other major change is reserving MIPS ABI version 5 for .MIPS.xhash, marking the need of support for .MIPS.xhash in the dynamic linker (again, addressed in the corresponding glibc patch). This is something which I am not sure of, especially after reading [5]. I am confused on whether this ABI version is reserved for IFUNC, or it can be used for this purpose.

2019-07-23SHF_GNU_MBIND requires ELFOSABI_GNUAlan Modra1-0/+2
When SHF_GNU_MBIND was added in the SHF_LOOS to SHF_HIOS range, it should have required ELFOSABI_GNU since these flags are already in use by other OSes. HPUX SHF_HP_TLS in fact has the same value. That means no place in binutils should test SHF_GNU_MBIND without first checking OSABI, and SHF_GNU_MBIND should not be set without also setting OSABI. At least, that's the ideal, but the patch accepts SHF_GNU_MBIND on ELFOSABI_NONE object files since gas didn't always set OSABI. However, to reinforce the fact that SHF_GNU_MBIND isn't proper without a non-zero OSABI, readelf will display the flag as LOOS+0 if OSABI isn't set. The clash with SHF_HP_TLS means that hppa64-linux either has that flag on .tbss sections or supports GNU_MBIND, not both. (hppa64-linux users, if there are any, may have noticed that GNU ld since 2017 mysteriously aligned their .tbss sections to a 4k boundary. That was one consequence of SHF_HP_TLS being blindly interpreted as SHF_GNU_MBIND.) Since it seems that binutils, gdb, gcc, glibc, and the linux kernel don't care about SHF_HP_TLS I took that flag out of .tbss for hppa64-linux. bfd/ * elf-bfd.h (enum elf_gnu_osabi): Add elf_gnu_osabi_mbind. * elf.c (_bfd_elf_make_section_from_shdr): Set elf_gnu_osabi_mbind.

2019-05-21AArch64: Implement choice between Cortex-A53 erratum workarounds. (PR ld/24373)Tamar Christina1-4/+26
The Cortex-A53 erratum currently has two ways it can resolve the erratum when using the flag --fix-cortex-a53-843419: 1) If the address is within the range of an ADR instruction it rewrites the ADRP into an ADR, and those doesn't need the use of a veneer. 2) If the address is not within range, it adds a branch to a veneer which will execute the final bit of the erratum workaround and branch back to the call site. When we do this we always generate the veneers and we always align the size of the text section to 4KB. This is because we only know which workaround we can use after all linking has finished and all addresses are known. This means even though the veneers are not used, we still generate the section and we still change the size of the input section. This is problematic for small memory devices as this would require the user to take about a ~4KB hit in memory even though it's not even used. Since there's no real way to restart the linking process from the final write phase this patch solves the issue by allowing the user more control over which erratum workaround gets used. Concretely this changes the option --fix-cortex-a53-843419 to take optional arguments --fix-cortex-a53-843419[=full|adr|adrp] - full (default): Use both ADRP and ADR workaround. This is equivalent to not specifying any options and is the default behavior before this patch. - adr: Only use the ADR workaround, this will not cause any increase in binary size but linking will fail if the referenced address is out of range of an ADR instruction. - adrp: Use only the ADRP workaround, this will never rewrite your ADRP. In the cases where the user knows how big their binaries are the `adr` option would prevent the unneeded overhead. bfd/ChangeLog: PR ld/24373 * bfd-in.h (enum erratum_84319_opts): New (bfd_elf64_aarch64_set_options, bfd_elf32_aarch64_set_options): Change int to enum erratum_84319_opts. * bfd-in2.h: Regenerate. * elfnn-aarch64.c (struct elf_aarch64_link_hash_table): Change fix_erratum_843419 to use new enum, remove fix_erratum_843419_adr.

2019-03-13[BFD, LD, AArch64, 3/3] Add --pac-plt to enable PLTs protected with PAC.Sudakshina Das1-0/+7
This is part of the patch series to add support for BTI and PAC in AArch64 linker. 1) This patch adds new definitions of PAC enabled PLTs and both BTI and PAC enabled PLTs. 2) It also defines the new dynamic tag DT_AARCH64_PAC_PLT for the PAC enabled PLTs. 3) This patch adds a new ld command line option: --pac-plt. In the presence of this option, the linker uses the PAC enabled PLTs and marks with DT_AARCH64_PAC_PLT. 4) In case both BTI and PAC are enabled the linker should pick PLTs enabled with both and also use dynamic tags for both.

enabled PLTs This is part of the patch series to add support for BTI and PAC in AArch64 linker. 1) This patch adds a new ld command line option: --force-bti. In the presence of this option, the linker enables BTI with the GNU_PROPERTY_AARCH64_FEATURE_1_BTI feature. This gives out warning in case of missing gnu notes for BTI in inputs. 2) It also defines a new set of BTI enabled PLTs. These are used either when all the inputs are marked with GNU_PROPERTY_AARCH64_FEATURE_1_BTI or when the new --force-bti option is used. This required adding new fields in elf_aarch64_link_hash_table so that we could make the PLT related information more generic. 3) It also defines a dynamic tag DT_AARCH64_BTI_PLT. The linker uses this whenever it picks BTI enabled PLTs.

2018-09-14PR ld/21375: MIPS: Fix non-zero run-time value for undefined weaksMaciej W. Rozycki1-1/+11
We have an issue in the MIPS backend, with the handling of undefined hidden and internal weak symbols. References to such symbols are supposed to resolve to 0 according to the ELF gABI[1]: "Unresolved weak symbols have a zero value." and the 64-bit MIPS psABI[2]: "If a symbol with one of these [hidden or internal] attributes has no definition within the executable/DSO being linked, then it must be resolved to allocated space if common, resolved to zero if weak, or an error reported otherwise." however if a GOT relocation is used, then a local GOT entry is created and used to satisfy the reference. Such an entry is then (in DSO and PIE binaries) subject to the usual load-time relocation, which means a non-zero value will be returned if the base address is non-zero. This will defeat the usual run-time sequence like: void a (void) __attribute__ ((visibility ("hidden"), weak)); void x (void) { if (a) a (); } This can be reproduced with this simple code: $ cat libtest.c extern int a __attribute__ ((visibility ("hidden"), weak)); int * x (void) { return &a; } $ cat test.c int *x (void); int main (void) { printf ("a: %p\n", x ()); return 0; } $ gcc -shared -fPIC -o libtest.so libtest.c $ gcc -o test test.c -Wl,-rpath,$(pwd) libtest.so $ ./test a: 0x77184000 $ The usual approach targets take is making all the steps required to assign a GOT entry for the symbol referred, and then leave its contents at zero with no dynamic relocation attached, therefore ensuring that the value does not change at load time. However this is not going to work with the implicitly relocated GOT the MIPS psABI specifies[3]: "The dynamic linker relocates the global offset table by first adding the difference between the base where the shared object is loaded and the value of the dynamic tag DT_MIPS_BASE_ADDRESS to all local global offset table entries." and we cannot therefore use the local GOT part. And we cannot offhand use the global part either, as the symbol would then have to be exported and possibly wrongly preempt symbols in other modules involved in the dynamic load, because as per the ELF gABI[1] we are not allowed to enter a hidden or internal symbol into the dynamic symbol table (and then use its associated GOT entry): "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." and: "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." So we have to choose something else. Our choice is further limited by the need for the reference associated with the GOT relocation to stay within the signed 16-bit limit from the GOT pointer base register, while being compliant with the ELF gABI and the MIPS psABI. However as Alan Modra has observed[4] one possibility is to edit (relax) the code such that the GOT reference is removed altogether. Based on these observations then modify MIPS BFD linker backend code to: 1. Interpret code associated with GOT relocations and relax the usual LW or LD instructions into a corresponding immediate load operation that places the value of 0 in the intended register, while leaving the GOT entry allocated and initialized as usually. 2. Leave any other instructions associated with GOT relocations in place and instead redirect the reference to a global GOT entry associated with a special `__gnu_absolute_zero' symbol created for this purpose, whose value is 0, SHN_ABS section marks it absolute, binding is global and export class protected, ensuring that the locally provided value is always used at load time, and that the value is not relocated by the dynamic loader. 3. Adjust any high-part GOT relocation used, typically associated with a LUI instruction, accordingly, so that run-time consistency is maintained, either by resolving to the original entry if the instruction associated with the corresponding low-part GOT relocation has been relaxed to an immediate load (in which case the value loaded with LUI will be overwritten), or by also redirecting the reference to `__gnu_absolute_zero' to complete the GOT access sequence if that symbol has been used. 4. Add a target `elf_backend_hide_symbol' hook, for the three MIPS ABIs, which prevents the `__gnu_absolute_zero' symbol from being forced local, to ensure that the redirection works and the symbol remains global/protected with existing linker scripts unchanged. 5. Observing the issue with handling SHN_ABS symbols in the GNU dynamic loader, covered by glibc PR 19818, set the EI_ABIVERSION field in the ELF file header produced to 4 (ABI_ABSOLUTE) if `__gnu_absolute_zero' symbol has been produced and the target configured indicates the GNU operating system, so that broken versions of the GNU dynamic loader gracefully reject the file in loading rather than going astray. Keep EI_ABIVERSION at the original value for other operating systems or if no `__gnu_absolute_zero' symbol has been made. The name of the special `__gnu_absolute_zero' has no meaning other than how a human reader can interpret it, as it is ignored in dynamic loading in the handling of the scenarios concerned. This is because the symbol resolves locally, and it's only the symbol's attributes that matter so that the associated GOT entry remains unchanged at load time. Therefore the name is somewhat arbitrary, observing however the need to use the name space reserved for the system so that it does not conflict with a possible user symbol, and hence the leading underscore, and also the `gnu' infix to denote a GNU feature. Other implementations wishing to address the problem in a similar way may choose a different name and have the solution still work, possibly with a mixture of modules used in a dynamic having symbols of different names provided, which will however not interact with each other due to the protected export class. The symbol can be referred explicitly, however the name is an internal implementation detail rather than a part of the ABI, and therefore no specific semantics is guaranteed. One limitation of this change is that if `__gnu_absolute_zero' has been already defined, then we do not wipe the old definition and all kinds of odd behavior can result. This is however like with other symbols we internally define, such as `_GLOBAL_OFFSET_TABLE_' or `__rld_map', and therefore left as a possible future enhancement. As an optimization the relaxation of LW and LD instructions to a load of immediate zero is always made, even SVR4 PIC code for code that will end up in a regular (non-PIE) executable, because there is a cache advantage with the avoidance of a load from the GOT, even if it is otherwise guaranteed to remain zero. It does not reliably happen though, due to a symbol exportation issue affecting executables, covered by PR ld/21805. One existing test case needs to be updated, as it triggers relaxation introduced with this change and consequently linker output does not match expectations anymore. As we want to keep the original issue covered with the test case modify it then to use the LWL instruction in place of LW, and adjust the output expected accordingly.

We force __ehdr_start to defined in before_allocation, then restore the type and a union after dynamic symbols have been allocated. The union contains a number of structs, all starting with a "next" pointer, and various fields depending on the symbol type. The old code restored the entire union, but it isn't necessary to restore the "next" pointer, and in fact it could be wrong if __ehdr_start happened to be last on the list and some symbols were added before restoring. * emultempl/elf32.em (before_allocation): Don't restore __ehdr_start u.*.next pointer.

2018-07-30Add support for the C_SKY series of processors.Andrew Jenner1-0/+355
This patch series is a new binutils port for C-SKY processors, including support for both the V1 and V2 processor variants. V1 is derived from the MCore architecture while V2 is substantially different, with mixed 16- and 32-bit instructions, a larger register set, a different (but overlapping) ABI, etc. There is support for bare-metal ELF targets and Linux with both glibc and uClibc. This code is being contributed jointly by C-SKY Microsystems and Mentor Graphics. C-SKY is responsible for the technical content and has proposed Lifang Xia and Yunhai Shang as port maintainers. (Note that C-SKY does have a corporate copyright assignment on file with the FSF.) Mentor Graphics' role has been cleaning up the code, adding documentation and additional test cases, etc, to address issues we anticipated reviewers would complain about. bfd * Makefile.am (ALL_MACHINES, ALL_MACHINES_CFILES): Add C-SKY.

2018-07-18ld: Enable using separate linker script for -z relroAndreas Krebbel1-1/+148
With this patch dedicated linker scripts can be generated for partial relro triggered by defining GENERATE_RELRO_SCRIPT in the target specific scripts. This is necessary for e.g. S/390 where usually the .got.plt comes first and prevents the relro segment from being extended across the non-plt GOT entries. The patch started with the work from Marcin taken from the mwk user branches. However, the patch needed substantial changes due to the 'separate code' feature which got committed in the meantime. ld/ChangeLog: 2018-07-18 Andreas Krebbel <krebbel@linux.ibm.com> Marcin Kościelnicki <koriakin@0x04.net> * emultempl/elf32.em: Add code to pick dedicated linker scripts for partial relro. * genscripts.sh: Generate dedicated linker scripts for partial relro.

2018-04-04Speed up direct linking with DLLs on Windows (1/2).Eric Botcazou2-244/+20
This patch deals with the auto-import feature. There are 2 versions of this feature: the original one, which was piggybacked on the OS loader with an optional help from the runtime (--enable-auto-import --enable-runtime-pseudo-reloc-v1) and is still the one mostly documented in the sources and manual; the enhanced one by Kai Tietz, which is entirely piggybacked on the runtime (--enable-auto-import --enable-runtime-pseudo-reloc-v2) and is the default for Mingw and Cygwin nowadays. The implementation is inefficient because of pe[p]_find_data_imports: for every undefined symbol, the function walks the entire set of relocations for all the input files and does a direct name comparison for each of them. This is easily fixable by using a hash-based map for v1 and a simple hash table for v2. This patch leaves v1 alone and only changes v2. It also factors out pe[p]_find_data_imports into a common function, removes old cruft left and right, and attempts to better separate the implementations of v1 and v2 in the code. ld/ * emultempl/pe.em (U_SIZE): Delete. (pe_data_import_dll): Likewise. (make_import_fixup): Return void, take 4th parameter and pass it down in call to pe_create_import_fixup. (pe_find_data_imports): Move to...

2018-02-27ld: Add --enable-separate-codeH.J. Lu1-0/+1
This patch adds --enable-separate-code to ld configure to turn on -z separate-code by default and enables it by default for Linux/x86. This avoids mixing code pages with data to improve cache performance as well as security. To reduce x86-64 executable and shared object sizes, the maximum page size is reduced from 2MB to 4KB when -z separate-code is turned on by default. Note: -z max-page-size= can be used to set the maximum page size. We compared SPEC CPU 2017 performance before and after this change on Skylake server. There are no any significant performance changes. Everything is mostly below +/-1%. bfd/ * config.in: Regenerated. * configure: Likewise. * configure.ac: Add --enable-separate-code.

2018-02-26ld error/warning messagesAlan Modra38-340/+363
This patch standardizes messages in ld, to better conform to the GNU coding standard. Besides issues of capitalization and full-stops, I've - Split up help messages for target options, so that adding a new option does not mean loss of translation for all the others. - Embedded tabs have been removed, since a user might have tab stops set at other than 8 char intervals. - Added missing program name (%P). ld isn't the compiler. - Put %F and %X first (and removed %X if %F was present). These can go anywhere, but look silly in the m%Fiddle of a message, and choosing "%P%F:" in some messages but "%F%P:" in others leads to the likelihood of duplication in ld.pot. Besides, the colon belongs with %P. * emulparams/call_nop.sh, * emulparams/cet.sh, * emulparams/elf32mcore.sh, * emultempl/aarch64elf.em * emultempl/aix.em, * emultempl/alphaelf.em, * emultempl/armcoff.em, * emultempl/armelf.em, * emultempl/avrelf.em, * emultempl/beos.em, * emultempl/bfin.em, * emultempl/cr16elf.em, * emultempl/elf32.em, * emultempl/elf-generic.em, * emultempl/hppaelf.em, * emultempl/linux.em, * emultempl/lnk960.em, * emultempl/m68hc1xelf.em, * emultempl/m68kcoff.em, * emultempl/m68kelf.em, * emultempl/metagelf.em, * emultempl/mipself.em, * emultempl/mmix-elfnmmo.em, * emultempl/mmo.em, * emultempl/msp430.em, * emultempl/nds32elf.em, * emultempl/nios2elf.em, * emultempl/pe.em, * emultempl/pep.em, * emultempl/ppc32elf.em, * emultempl/ppc64elf.em, * emultempl/scoreelf.em, * emultempl/sh64elf.em, * emultempl/spuelf.em, * emultempl/sunos.em, * emultempl/tic6xdsbt.em, * emultempl/ticoff.em, * emultempl/v850elf.em, * emultempl/vms.em, * emultempl/vxworks.em, * emultempl/xtensaelf.em, * ldcref.c, * ldctor.c, * ldexp.c, * ldfile.c, * ldgram.y, * ldlang.c, * ldmain.c, * ldmisc.c, * ldwrite.c, * lexsup.c, * mri.c, * pe-dll.c, * plugin.c: Standardize error/warning messages. * testsuite/ld-arc/jli-overflow.err, * testsuite/ld-arm/cmse-implib-errors.out, * testsuite/ld-arm/cmse-new-earlier-later-implib.out, * testsuite/ld-arm/cmse-new-implib-not-sg-in-implib.out, * testsuite/ld-arm/cmse-new-wrong-implib.out, * testsuite/ld-arm/cmse-veneers-no-gnu_sgstubs.out, * testsuite/ld-arm/cmse-veneers-wrong-entryfct.out, * testsuite/ld-arm/vxworks1-static.d, * testsuite/ld-cris/tls-err-20x.d, * testsuite/ld-cris/tls-err-29.d, * testsuite/ld-cris/tls-err-31.d, * testsuite/ld-cris/tls-err-33.d, * testsuite/ld-cris/tls-err-35.d, * testsuite/ld-cris/tls-err-37.d, * testsuite/ld-cris/tls-err-39.d, * testsuite/ld-cris/tls-err-41.d, * testsuite/ld-cris/tls-err-43.d, * testsuite/ld-cris/tls-err-45.d, * testsuite/ld-cris/tls-err-47.d, * testsuite/ld-cris/tls-err-49.d, * testsuite/ld-cris/tls-err-51.d, * testsuite/ld-cris/tls-err-67.d, * testsuite/ld-elf/dwarf2.err, * testsuite/ld-elf/dwarf3.err, * testsuite/ld-elf/orphan-5.l, * testsuite/ld-elf/orphan-6.l, * testsuite/ld-i386/vxworks1-static.d, * testsuite/ld-mips-elf/bal-jalx-pic-micromips-n32.d, * testsuite/ld-mips-elf/bal-jalx-pic-micromips-n64.d, * testsuite/ld-mips-elf/bal-jalx-pic-micromips.d, * testsuite/ld-mips-elf/bal-jalx-pic-n32.d, * testsuite/ld-mips-elf/bal-jalx-pic-n64.d, * testsuite/ld-mips-elf/bal-jalx-pic.d, * testsuite/ld-mips-elf/jal-global-overflow-1.d, * testsuite/ld-mips-elf/jal-local-overflow-1.d, * testsuite/ld-mips-elf/mode-change-error-1.d, * testsuite/ld-mips-elf/unaligned-branch-2.d, * testsuite/ld-mips-elf/unaligned-branch-ignore-2.d, * testsuite/ld-mips-elf/unaligned-branch-ignore-micromips.d, * testsuite/ld-mips-elf/unaligned-branch-ignore-mips16.d, * testsuite/ld-mips-elf/unaligned-branch-ignore-r6-1.d, * testsuite/ld-mips-elf/unaligned-branch-micromips.d, * testsuite/ld-mips-elf/unaligned-branch-mips16.d, * testsuite/ld-mips-elf/unaligned-branch-r6-1.d, * testsuite/ld-mips-elf/unaligned-branch-r6-2.d, * testsuite/ld-mips-elf/unaligned-branch.d, * testsuite/ld-mips-elf/unaligned-jalx-1.d, * testsuite/ld-mips-elf/unaligned-jalx-3.d, * testsuite/ld-mips-elf/unaligned-jalx-addend-1.d, * testsuite/ld-mips-elf/unaligned-jalx-addend-3.d, * testsuite/ld-mips-elf/unaligned-jalx-addend-micromips-1.d, * testsuite/ld-mips-elf/unaligned-jalx-addend-mips16-1.d, * testsuite/ld-mips-elf/unaligned-jalx-micromips-1.d, * testsuite/ld-mips-elf/unaligned-jalx-mips16-1.d, * testsuite/ld-mips-elf/unaligned-jump-micromips.d, * testsuite/ld-mips-elf/unaligned-jump-mips16.d, * testsuite/ld-mips-elf/unaligned-jump.d, * testsuite/ld-mips-elf/unaligned-ldpc-1.d, * testsuite/ld-mips-elf/unaligned-lwpc-1.d, * testsuite/ld-mips-elf/undefined.d, * testsuite/ld-mips-elf/vxworks1-static.d, * testsuite/ld-mmix/bpo-20.d, * testsuite/ld-mmix/bpo-20m.d, * testsuite/ld-mmix/bpo-7.d, * testsuite/ld-mmix/bpo-7m.d, * testsuite/ld-mmix/bpo-8.d, * testsuite/ld-mmix/bpo-8m.d, * testsuite/ld-mmix/greg-17.d, * testsuite/ld-mmix/greg-18.d, * testsuite/ld-mmix/greg-8.d, * testsuite/ld-mmix/greg-9.d, * testsuite/ld-plugin/plugin-14.d, * testsuite/ld-plugin/plugin-15.d, * testsuite/ld-plugin/plugin-16.d, * testsuite/ld-plugin/plugin-20.d, * testsuite/ld-plugin/plugin-21.d, * testsuite/ld-plugin/plugin-22.d, * testsuite/ld-plugin/plugin-23.d, * testsuite/ld-plugin/plugin-6.d, * testsuite/ld-plugin/plugin-7.d, * testsuite/ld-plugin/plugin-8.d, * testsuite/ld-powerpc/aix-weak-3-32.d, * testsuite/ld-powerpc/aix-weak-3-64.d, * testsuite/ld-powerpc/vxworks1-static.d, * testsuite/ld-sh/vxworks1-static.d, * testsuite/ld-sparc/vxworks1-static.d, * testsuite/ld-undefined/undefined.exp, * testsuite/ld-x86-64/pie1.d: Update for changed errors and warnings. * testsuite/ld-elf/warn1.d, * testsuite/ld-elf/warn2.d: Correct regex.

2018-02-07Revert "PowerPC PLT speculative execution barriers"Alan Modra2-39/+3
This reverts most of commit 1be5d8d3bb. Left in place are addition of --no-plt-align to some ppc32 ld tests and the ld.texinfo --no-plt-thread-safe fix.
2018-01-18solaris2.em: Fold after_allocation into before_allocationH.J. Lu1-41/+27
Since all ELF linkers call check_relocs after opening all inputs, we can fold after_allocation into before_allocation so that local dynamic symbols will be placed before global dynamic symbols in .dynsym section. This fixed: FAIL: Common symbol override test (auxiliary shared object build) FAIL: ld-elf/pr19617a FAIL: ld-elf/pr19698 for i386-solaris2.12 and x86_64-solaris2.12 targets. PR ld/22728 * emultempl/solaris2.em (elf_solaris2_after_allocation): Fold into ... (elf_solaris2_before_allocation): This. (LDEMUL_AFTER_ALLOCATION): Removed.
