2024-11-26nios2: Remove binutils support for Nios II target.Sandra Loosemore1-1/+0
The Nios II architecture has been EOL'ed by the vendor. This patch removes all binutils, bfd, gas, binutils, and opcodes support for this target with the exception of the readelf utility. (The ELF EM_* number remains valid and the relocation definitions from the Nios II ABI will never change in future, so retaining the readelf support seems consistent with its purpose as a utility that tries to parse the headers in any ELF file provided as an argument regardless of target.)

2022-05-27opcodes/i386: remove trailing whitespace from insns with zero operandsAndrew Burgess8-16/+16
While working on another patch[1] I had need to touch this code in i386-dis.c: ins->obufp = ins->mnemonicendp; for (i = strlen (ins->obuf) + prefix_length; i < 6; i++) oappend (ins, " "); oappend (ins, " "); (*ins->info->fprintf_styled_func) (ins->info->stream, dis_style_mnemonic, "%s", ins->obuf); What this code does is add whitespace after the instruction mnemonic and before the instruction operands. The problem I ran into when working on this code can be seen by assembling this input file: .text nop retq Now, when I disassemble, here's the output. I've replaced trailing whitespace with '_' so that the issue is clearer: Disassembly of section .text: 0000000000000000 <.text>: 0: 90 nop 1: c3 retq___ Notice that there's no trailing whitespace after 'nop', but there are three spaces after 'retq'! What happens is that instruction mnemonics are emitted into a buffer instr_info::obuf, then instr_info::mnemonicendp is setup to point to the '\0' character at the end of the mnemonic. When we emit the whitespace, this is then added starting at the mnemonicendp position. Lets consider 'retq', first the buffer is setup like this: 'r' 'e' 't' 'q' '\0' Then we add whitespace characters at the '\0', converting the buffer to this: 'r' 'e' 't' 'q' ' ' ' ' ' ' '\0' However, 'nop' is actually an alias for 'xchg %rax,%rax', so, initially, the buffer is setup like this: 'x' 'c' 'h' 'g' '\0' Then in NOP_Fixup we spot that we have an instruction that is an alias for 'nop', and adjust the buffer to this: 'n' 'o' 'p' '\0' '\0' The second '\0' is left over from the original buffer contents. However, when we rewrite the buffer, we don't afjust mnemonicendp, which still points at the second '\0' character. Now, when we insert whitespace we get: 'n' 'o' 'p' '\0' ' ' ' ' ' ' ' ' '\0' Notice the whitespace is inserted after the first '\0', so, when we print the buffer, the whitespace is not printed. The fix for this is pretty easy, I can change NOP_Fixup to adjust mnemonicendp, but now a bunch of tests start failing, we now produce whitespace after the 'nop', which the tests don't expect. So, I could update the tests to expect the whitespace.... ...except I'm not a fan of trailing whitespace, so I'd really rather not. Turns out, I can pretty easily update the whitespace emitting code to spot instructions that have zero operands and just not emit any whitespace in this case. So this is what I've done. I've left in the fix for NOP_Fixup, I think updating mnemonicendp is probably a good thing, though this is not really required any more. I've then updated all the tests that I saw failing to adjust the expected patterns to account for the change in whitespace. [1] https://sourceware.org/pipermail/binutils/2022-April/120610.html

2021-09-03CC_FOR_TARGET et alAlan Modra1-5/+5
The top level Makefile, the ld Makefile and others, define CC_FOR_TARGET to be a compiler for the binutils target machine. This is the compiler that should be used for almost all tests with C source. There are _FOR_TARGET versions of CFLAGS, CXX, and CXXFLAGS too. This was all supposed to work with the testsuite .exp files using CC for the target compiler, and CC_FOR_HOST for the host compiler, with the makefiles passing CC=$CC_FOR_TARGET and CC_FOR_HOST=$CC to the runtest invocation. One exception to the rule of using CC_FOR_TARGET is the native-only ld bootstrap test, which uses the newly built ld to link a copy of itself. Since the files being linked were created with the host compiler, the boostrap test should use CC and CFLAGS, in case some host compiler option provides needed libraries automatically. However, bootstrap.exp used CC where it should have used CC_FOR_HOST. I set about fixing that problem, then decided that playing games in the makefiles with CC was a bad idea. Not only is it confusing, but other dejagnu code knows about CC_FOR_TARGET. See dejagnu/target.exp. So this patch gets rid of the makefile variable renaming and changes all the .exp files to use the correct _FOR_TARGET variables. CC_FOR_HOST and CFLAGS_FOR_HOST disappear. A followup patch will correct bootstrap.exp to use CFLAGS, and a number of other things I noticed. binutils/ * testsuite/lib/binutils-common.exp (run_dump_test): Use CC_FOR_TARGET and CFLAGS_FOR_TARGET rather than CC and CFLAGS. ld/ * Makefile.am (check-DEJAGNU): Don't set CC to CC_FOR_TARGET and similar.

2021-02-14ld testsuite: change unresolved to unsupported/failAlan Modra1-4/+4
"unresolved" as a test result means runtest returns an error, which can be confusing when there is no apparent error unless you look in .log files. In particular many tests are skipped without reporting an error if no target C compiler is found, but if a target C compiler is found but won't compile a testcase for some reason we used to mark the test as unresolved.

2021-01-07ELF: Don't generate unused section symbolsH.J. Lu10-36/+36
For ELF targets, section symbols are required only for relocations. With -ffunction-sections -fdata-sections, there can be many unused section symbols. Sizes of libstdc++.a on Linux/x86-64 in GCC 11 are With unused section symbols : 39411698 bytes Without unused section symbols: 39227002 bytes The unused section symbols in libstdc++.a occupy more than 180 KB. Add BSF_SECTION_SYM_USED to indicate if a section symbol should be included in the symbol table. The BSF_SECTION_SYM_USED should be set if the section symbol is used for relocation or the section symbol is always included in the symbol table. Add keep_unused_section_symbols to bfd_target to indicate if unused section symbols should be kept. If TARGET_KEEP_UNUSED_SECTION_SYMBOLS is defined as FALSE, unused ection symbols will be removed.

2020-10-16RISC-V: Support GNU indirect functions.Nelson Chu1-2/+2
Generally, glibc dynamic linker should have two ways to deal with ifunc - one is to handle the IRELATIVE relocations for the non-preemtive ifunc symbols, the other is to handle the R_RISCV_32/64 and R_RISCV_JUMP_SLOT relocations with the STT_IFUNC preemtive symbols. No matter which method is used, both of them should get the resolved ifunc symbols at runtime. Therefore, linker needs to generate the correct dynamic relocations for ifunc to make sure the the dynamic linker works well. For now, there are thirteen relocations are supported for ifunc in GNU ld, * R_RISCV_CALL and R_RISCV_CALL_PLT: The RISC-V compiler won't generate R_RISCV_JAL directly to jump to an ifunc. Besides, we disable the relaxations for the relocation referenced to ifunc, so just handling the R_RISCV_CALL and R_RISCV_CALL_PLT should be enough. Linker should generate a .plt entry and a .got.plt entry for it, and also needs to insert a dynamic IRELATIVE in the .got.plt enrty, or insert a R_RISCV_JUMP_SLOT when generating shared library. * R_RISCV_PCREL_HI20 and R_RISCV_PCREL_LO12_I/S: LA/LLA pattern with local fPIC ifunc symbol, or any non-PIC ifunc symbol. The PC-relative relocation. The current linker will deal with them in the same way as R_RISCV_CALL_PLT. * R_RISCV_GOT_HI20 and R_RISCV_PCREL_LO12_I/S: LA pattern with global PIC ifunc symbol. Linker should insert a dynamic IRELATIVE in the .got entry, or insert a R_RISCV_32/64 when generating shared library. * R_RISCV_32 and R_RISCV_64: Store the ifunc symbol into the data section. Linker should insert a dynamic IRELATIVE in the data section, or insert a R_RISCV_32/64 when generating shared library. * R_RISCV_HI20 and R_RISCV_LO12_I/S: The LUI + ADDI/LW/SW patterns. The absolute access relocation. The medlow model without the -fPIC compiler option should generate them. The ld ifunc testsuites "Build pr23169a" and "Build pr23169d" need the relocations, they are in the ld/testsuite/ld-ifunc/, and need compiler support. However, we also made some optimizations with reference to x86, * If GOT and PLT relocations refer to the same ifunc symbol when generating pie, then they can actually share a .got entry without creating two entries to store the same value and relocation. * If GOT, PLT and DATA relocations refer to the same ifunc symbol when generating position dependency executable, then linker will fill the address of .plt entry into the corresponding .got entry and data section, without insert any dynamic relocations for the GOT and DATA relocations. For the ifunc testcases, there are three types of them, 1. ifunc-reloc-*: Only check the single type of relocation refers to ifunc symbol. * ifunc-reloc-call: R_RISCV_CALL and R_RISCV_CALL_PLT. * ifunc-reloc-data: R_RISCV_32 and R_RISCV_64. * ifunc-reloc-got: R_RISCV_GOT_HI20 and R_RISCV_PCREL_LO_I/S. * ifunc-reloc-pcrel: R_RISCV_PCREL_HI20 and R_RISCV_PCREL_LO_I/S. 2. ifunc-[nonplt|plt]-*: If we don't have PLT relocs, then don't need to create the PLT and it's .plt entries. * ifunc-nonplt: Combine R_RISCV_GOT_HI20 and R_RISCV_32/64. * ifunc-plt: Combine all ifunc relocations. 3. ifunc-seperate-*: If we link the ifunc caller and resolver into the same module (link the objects), then the results are the same as the ifunc-reloc-* and ifunc-[noplt|plt]-* testcases. Consider the cases that the ifunc callers and resolver are in the different modules, that is, we compile the ifunc resolver to the shared library first, and then link it with the ifunc callers. The output of ifunc callers should be the same as the normal STT_FUNC cases, and the shared ifunc resolver should define the symbols as STT_IFUNC. The R_RISCV_PCREL_HI20 reloc is special. It should be linked and resolved locally, so if the ifunc resolver is defined in other modules (other shared libraries), then the R_RISCV_PCREL_HI20 is unresolvable, and linker should issue an unresolvable reloc error. bfd/ * elfnn-riscv.c: Include "objalloc.h" since we need objalloc_alloc.

2020-07-15x86: avoid attaching suffixes to unambiguous insnsJan Beulich10-64/+64
"Unambiguous" is is in particular taking as reference the assembler, which also accepts certain insns - despite them allowing for varying operand size, and hence in principle being ambiguous - without any suffix. For example, from the very beginning of the life of x86-64 I had trouble understanding why a plain and simple RET had to be printed as RETQ. In case someone really used the 16-bit form, RETW disambiguates the two quite fine.
2020-07-09pr18841 tests on powerpc64Alan Modra1-9/+9
The PR18841 test does cross-module calls from within an ifunc resolver, which is nasty, and not supported in general since the called function may not be relocated. In this case the called function (zoo) is just a stub so doesn't need relocating, but on ppc64 the function descriptor for zoo in the executable won't be relocated at the time the shared library ifunc resolver runs. That means the test will fail if your compiler generates PIEs by default. PR 18841 * testsuite/ld-ifunc/ifunc.exp: Run pr18841 tests non-pie.

2020-04-02ld: Disable ifunc tests on SolarisRainer Orth42-42/+39
A couple of ld ifunc tests currently FAIL on 64-bit Solaris/x86: FAIL: ld-ifunc/ifunc-10-x86-64 FAIL: ld-ifunc/ifunc-11-x86-64 FAIL: ld-ifunc/ifunc-12-x86-64 FAIL: ld-ifunc/ifunc-13-x86-64 FAIL: ld-ifunc/ifunc-14a-x86-64 FAIL: ld-ifunc/ifunc-14b-x86-64 FAIL: ld-ifunc/ifunc-14c-x86-64 FAIL: ld-ifunc/ifunc-14d-x86-64 FAIL: ld-ifunc/ifunc-14e-x86-64 FAIL: ld-ifunc/ifunc-14f-x86-64 FAIL: ld-ifunc/ifunc-15-x86-64 FAIL: ld-ifunc/ifunc-17a-x86-64 FAIL: ld-ifunc/ifunc-17b-x86-64 FAIL: ld-ifunc/ifunc-2-local-x86-64-now FAIL: ld-ifunc/ifunc-2-local-x86-64 FAIL: ld-ifunc/ifunc-2-x86-64-now FAIL: ld-ifunc/ifunc-2-x86-64 FAIL: ld-ifunc/ifunc-20-x86-64 FAIL: ld-ifunc/pr17154-x86-64-now FAIL: ld-ifunc/pr17154-x86-64 For one, the actual error is weird: ./ld-new: target elf64-x86-64 not found failed with: <./ld-new: target elf64-x86-64 not found>, no expected output FAIL: ld-ifunc/ifunc-10-x86-64 although ld -V does report the elf_x86_64 emulation as supported: $ ./ld/ld-new -V GNU ld (GNU Binutils) 2.34.50.20200328 Supported emulations: elf_x86_64_sol2 elf_x86_64 [...] When using ld -m elf_x86_64_sol2 instead, one of the testcases links successfully. However, there's no point in pursuing this: Solaris does not support ifunc, as can be seen in <sys/elf.h>: /* * GNU/Linux specific symbol type not used by Solaris */ #define STT_GNU_IFUNC 10 and never will, given that it has symbol capabilities as solution to effectively the same problem: http://www.linker-aliens.org/blogs/rie/entry/symbol_capabilitie/ Therefore this patch disables ifunc testing on Solaris completely by removing Solaris from binutils/testsuite/lib/binutils-common.exp (supports_gnu_osabi). The ifunc part is justified above. SHF_GNU_MBIND is in the OS-specific range and conflicts with #define SHF_SUNW_REALLOC 0x01000000 /* internal: krtld realloc */ While the comment suggests this might be relocatable without too much problems, the description of mbind (no formal spec AFAICS, just the comment in the binutils patch submission) strongly suggests that this isn't relevant to Solaris at all. Indirectly, clearing supports_gnu_osabi on Solaris disables supports_gnu_unique. Again, Solaris <sys/elf.h> has /* * GNU/Linux specific binding not used by Solaris */ #define STB_GNU_UNIQUE 10 so this seems the right thing to do. Afterwards, one can remove the explicit mentions of *-*-solaris2* in quite a number of (but not all) the ld-ifunc dump file notarget lists. There's one fallout, though: two gas tests now XPASS because they are xfail'ed for !supports_gnu_osabi: XPASS: mbind sections 12 XPASS: mbind section contents 16 XPASS: mbind sections 16 XPASS: mbind section contents 16 To fix that, I've changed #xfail: ![supports_gnu_osabi] to notarget.

2019-04-24Use better test for usable compiler in ld testsuite.Sandra Loosemore1-1/+1
The ld testsuite includes numerous tests that depend on being able to compile and link programs with the C compiler. Some of these tests use [which $CC] to check for the presence of the compiler before proceeding with the test, but run_ld_link_exec_tests and run_cc_link_tests give ERRORs if compilation fails. Also, even if $CC is defined and present, it may not be usable due to missing libraries, etc. This patch adds a new procedure check_compiler_available that attempts to build an empty program and caches the result. Uses of [which $CC] are replaced with calls to this procedure, and run_ld_link_exec_tests and run_cc_link_tests now also guard attempts to use $CC. 2019-04-24 Sandra Loosemore <sandra@codesourcery.com> ld/ * testsuite/config/default.exp: Use [check_compiler_available] instead of [which $CC]. * testsuite/ld-auto-import/auto-import.exp: Likewise. * testsuite/ld-cygwin/exe-export.exp: Likewise. * testsuite/ld-elf/audit.exp: Likewise. * testsuite/ld-elf/compress.exp: Likewise. * testsuite/ld-elf/dwarf.exp: Likewise. * testsuite/ld-elf/elf.exp: Likewise. * testsuite/ld-elf/indirect.exp: Likewise. * testsuite/ld-elf/linux-x86.exp: Likewise. * testsuite/ld-elf/shared.exp: Likewise. * testsuite/ld-elf/tls.exp: Likewise. * testsuite/ld-elf/wrap.exp: Likewise. * testsuite/ld-elfcomm/elfcomm.exp: Likewise. * testsuite/ld-elfvers/vers.exp: Likewise. * testsuite/ld-elfvsb/elfvsb.exp: Likewise. * testsuite/ld-elfweak/elfweak.exp: Likewise. * testsuite/ld-gc/gc.exp: Likewise. * testsuite/ld-i386/i386.exp: Likewise. * testsuite/ld-i386/no-plt.exp: Likewise. * testsuite/ld-i386/tls.exp: Likewise. * testsuite/ld-ifunc/ifunc.exp: Likewise. * testsuite/ld-mn10300/mn10300.exp: Likewise. * testsuite/ld-pe/pe-compile.exp: Likewise. * testsuite/ld-pe/pe-run.exp: Likewise. * testsuite/ld-pe/pe-run2.exp: Likewise. * testsuite/ld-pie/pie.exp: Likewise. * testsuite/ld-plugin/lto.exp: Likewise. * testsuite/ld-plugin/plugin.exp: Likewise. * testsuite/ld-scripts/crossref.exp: Likewise. * testsuite/ld-sh/sh.exp: Likewise. * testsuite/ld-shared/shared.exp: Likewise. * testsuite/ld-size/size.exp: Likewise. * testsuite/ld-srec/srec.exp: Likewise. * testsuite/ld-undefined/undefined.exp: Likewise. * testsuite/ld-unique/unique.exp: Likewise. * testsuite/ld-x86-64/mpx.exp: Likewise. * testsuite/ld-x86-64/no-plt.exp: Likewise. * testsuite/ld-x86-64/tls.exp: Likewise. * testsuite/ld-x86-64/x86-64.exp: Likewise. * testsuite/lib/ld-lib.exp (run_ld_link_exec_tests): Call check_compiler_available before trying to use the compiler.

The aarch64 ifunc error message test was changed to no longer expect this error message as this is now an accepted combination. This patch also disables the executable tests added by H.J.

2018-07-10ld testsuite use of notargetAlan Modra1-1/+0
Much of the time it is better to use xfail rather than notarget to hide a testsuite failure no one is planning on fixing. 1) When a target is fixed, an inappropriate xfail results in XPASS whereas notarget is silent. Leaving in an inappropriate notarget entry risks the bug reappearing later, silently. 2) Tests might be used as a template for a new test, carrying over notarget and/or xfail. Inappropriate notarget entries are silent. 3) An xfailed test that mysteriously XPASSes might actually indicate a bug. * testsuite/ld-elf/attributes.d: Use xfail rather than notarget. * testsuite/ld-elf/hash.d: Likewise. * testsuite/ld-elf/orphan-10.d: Likewise. * testsuite/ld-elf/overlay.d: Likewise. * testsuite/ld-elf/pr14926.d: Likewise. * testsuite/ld-elf/pr17550d.d: Likewise. * testsuite/ld-elf/pr19539.d: Likewise. * testsuite/ld-elf/pr22319.d: Likewise. * testsuite/ld-misc/defsym1.d: Likewise. * testsuite/ld-pe/pr19803.d: Likewise. * testsuite/ld-scripts/assign-loc.d: Likewise. * testsuite/ld-scripts/defined4.d: Likewise. * testsuite/ld-scripts/empty-address-1.d: Likewise. * testsuite/ld-scripts/empty-address-2a.d: Likewise. * testsuite/ld-scripts/empty-address-2b.d: Likewise. * testsuite/ld-scripts/fill.d: Likewise. * testsuite/ld-scripts/fill16.d: Likewise. * testsuite/ld-scripts/pr14962.d: Likewise. * testsuite/ld-scripts/pr14962-2.d: Likewise. * testsuite/ld-unique/pr21529.d: Likewise. * testsuite/ld-elf/compress1a.d: Likewise, and adjust targets. * testsuite/ld-elf/compressed1a.d: Likewise. * testsuite/ld-elf/compressed1d.d: Likewise. * testsuite/ld-elf/compressed1e.d: Likewise. * testsuite/ld-elf/eh5.d: Likewise. * testsuite/ld-elf/group8a.d: Likewise. * testsuite/ld-elf/linkonce2.d: Likewise. * testsuite/ld-elf/orphan-9.d: Likewise. * testsuite/ld-elf/pr17550a.d: Likewise. * testsuite/ld-elf/pr17550b.d: Likewise. * testsuite/ld-elf/pr17550c.d: Likewise. * testsuite/ld-elf/pr19162.d: Likewise. * testsuite/ld-elf/pr21884.d: Likewise. * testsuite/ld-gc/pr19167.d: Likewise. * testsuite/ld-gc/pr20022.d: Likewise. * testsuite/ld-gc/start.d: Likewise. * testsuite/ld-elf/orphan-11.d: Delete notarget. * testsuite/ld-elf/orphan-12.d: Likewise. * testsuite/ld-gc/stop.d: Likewise. * testsuite/ld-scripts/empty-address-3a.d: Likewise. * testsuite/ld-scripts/empty-address-3b.d: Likewise. * testsuite/ld-ifunc/pr17154-x86-64-now.d: Delete duplicate notarget. * testsuite/ld-scripts/section-match-1.d: Comment fix.

2018-06-08Define various symbols conditionally in shared librariesAlan Modra10-127/+127
The values of symbols in shared libraries like _end, _edata, and __bss_start are generally not that useful outside of the shared library. This patch defines them conditionally with PROVIDE, since a shared library might need the local value. An example is glibc ld.so local access to "_begin", "_etext" and "_end". (ld.so gains access to the local values by making the references using hidden visibility. That makes the definitions hidden too.) We can't use PROVIDE_HIDDEN in the linker scripts because the shared library might need the value of the symbol in the executable. An example is freebsd libc dynamic access to "_end".

2018-03-09Fix Sparc, s390 and AArch64 targets so that they can handle relocs against ↵Nick Clifton3-0/+116
ifunc symbols found in note sections. Following on from PR 22929, I have found the same problem exists with other ifunc supporting targets too. Plus see this link for the bug being reported against the s390x binutils for Fedora rawhide: https://bugzilla.redhat.com/show_bug.cgi?id=1553705 So I am going to check in the patch below which applies the same change that H.J. made for the x86_64 target to the other affected targets. (Specifically: S390, AArch64 and Sparc). Plus it adds a new test to the linker testsuite to make sure that this problem stays fixed. bfd * elf64-s390.c (elf_s390_relocate_section): Move check for relocations against non-allocated sections to before the code that handles ifunc relocations. * elf32-s390.c (elf_s390_relocate_section): Likewise. * elfnn-aarch64.c (elfNN_aarch64_final_link_relocate): Treat relocs against IFUNC symbols in non-allocated sections as relocs against FUNC symbols. * elfxx-sparc.c (_bfd_sparc_elf_relocate_section): Likewise. ld * testsuite/ld-ifunc/ifuncmod5.s: New test.
