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.

2018-07-20[PATCH, LD, AArch64] Fix ifunc testismsAndre Simoes Dias Vieira1-1/+1
This patch fixes some ifunc testisms after H.J. Lu's patch to enable the use of IFUNC pointers in position dependent code for binutils. See PR LD/23169 in binutils bugzilla. 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. Lu for aarch64, just as Alan Modra did with his patch, as these tests only seem to work on some architectures. ld/ChangeLog: 2018-07-19 Andre Vieira <andre.simoesdiasvieira@arm.com> * testsuite/ld-aarch64/ifunc-9.d: Remove no longer expected error. * testsuite/ld-ifunc/ifunc.exp: Disable tests for aarch64.
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".

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.

2017-11-07readelf ngettext fixesAlan Modra15-21/+21
This patch is a first pass at fixing readelf message pluralization. I've deliberately not fixed the "out of memory" errors since it's very unlikely that they will ever be complaining about not being able to allocate for a single entry, and a few others where the size is very unlikely to be 1 byte. Then there are messages like this one: "Out of %lu items there are %zu bucket clashes (longest of %zu entries).\n" I suppose this could be split into three parts, "Of %lu items ", "there are %zu bucket clashes ", and "(longest of %zu entries).\n", each part being printed separately, but that might not be ideal for sentence construction in other languages. For now I'm punting on this one. Changes to readelf output require lots of testsuite adjustment.. binutils/ * dwarf.c (read_uleb128): Properly pluralize messages.

When ld is running with something other than --hash-style=sysv by default, numerous tests need tweaking. Most of the changes just add --hash-style=sysv.

2017-05-08x86-64: Improve PLT generation and synthetic PLT symbolsH.J. Lu4-0/+129
On x86-64, the procedure linkage table (PLT) is used to 1. Call external function. 2. Call internal IFUNC function. The best implementation is selected for the target processor at run-time. 3. Act as the canonical function address. 4. Support LD_AUDIT to audit external function calls. 5. Support LD_PROFILE to profile external function calls. PLT looks like: PLT0: push GOT[1] jmp *GOT[2] nop PLT1: jmp *GOT[name1_index] push name1_reloc_index jmp PLT0 GOT is an array of addresses. Initially the GOT entry of name1 is filled with the address of the "push name1_reloc_index" instruction. The function, name1, is called via "jmp *GOT[name1]" in the PLT entry. Even when lazy binding is disabled by "-z now", the PLT0 entry may still be used with LD_AUDIT or LD_PROFILE if PLT entry is used for canonical function address. When linker is invoked with "-z bndplt", a different PLT layout in .plt is used: PLT0: push GOT[1] bnd jmp *GOT[2] nop PLT1: push name1_reloc_index bnd jmp PLT0 nop together with a second PLT section, .pl.bnd: PLT1: bnd jmp *GOT[name1_index] nop where the GOT entry of name1 is filled with the address of the push instruction of the corresponding entry in .plt. 1. With lazy binding, when the external function, name1, is called the first time, dynamic linker is called via PLT0 to update GOT[name1_index] with the actual address of name1 and transfers control to name1 afterwards. 2. PLT is also used to call a local IFUNC function, name1, run-time loader updates GOT[name1_index] when loading the module. This patch 1. Remove PLT layout configurations from x86-64 backend_data. 2. Add generic, lay and non-lazy PLT layout configurations to x86-64 link_hash_table. Generic PLT layout includes the PLT entry templates, information how to update the first instruction in PLT and PLT eh_frame informaton, which are initialized in x86-64 setup_gnu_properties, based on "-z bndplt" and target selection. PLT section alignment is also set to PLT entry size for non-NaCl target. 3. Remove elf_x86_64_create_dynamic_sections. create_dynamic_sections isn't always called, but GOT relocations need GOT relocations. Instead, create all x86-64 specific dynamic sections with alignment to their entry size in x86-64 setup_gnu_properties, which initializes elf.dynobj, so that x86-64 check_relocs can be simplified. 4. Rewrite elf_x86_64_get_synthetic_symtab to check PLT sections against all dynamic relocations to support both lazy and non-lazy PLTs. There is no change in PLT.

2017-05-08i386: Improve PLT generation and synthetic PLT symbolsH.J. Lu4-0/+138
On i386, the procedure linkage table (PLT) is used to 1. Call external function. 2. Call internal IFUNC function. The best implementation is selected for the target processor at run-time. 3. Act as the canonical function address. 4. Support LD_AUDIT to audit external function calls. 5. Support LD_PROFILE to profile external function calls. PLT looks like: PLT0: push GOT[1] jmp *GOT[2] nop PLT1: jmp *GOT[name1_index] push name1_reloc_index jmp PLT0 GOT is an array of addresses. Initially the GOT entry of name1 is filled with the address of the "push name1_reloc_index" instruction. The function, name1, is called via "jmp *GOT[name1]" in the PLT entry. Even when lazy binding is disabled by "-z now", the PLT0 entry may still be used with LD_AUDIT or LD_PROFILE if PLT entry is used for canonical function address. 1. With lazy binding, when the external function, name1, is called the first time, dynamic linker is called via PLT0 to update GOT[name1_index] with the actual address of name1 and transfers control to name1 afterwards. 2. PLT is also used to call a local IFUNC function, name1, run-time loader updates GOT[name1_index] when loading the module. This patch 1. Remove PLT layout configurations from i386 backend_data. 2. Add generic, lay and non-lazy PLT layout configurations to i386 link_hash_table. Generic PLT layout includes the PLT entry templates, information how to update the first instruction in PLT and PLT eh_frame informaton, which are initialized in i386 setup_gnu_properties, based on PIC and target selection. PLT section alignment is also set to PLT entry size for non-NaCl/VxWorks target. 3. Remove elf_i386_create_dynamic_sections. create_dynamic_sections isn't always called, but GOT relocations need GOT relocations. Instead, create all i386 specific dynamic sections in i386 setup_gnu_properties, which initializes elf.dynobj, so that i386 check_relocs can be simplified. 4. Rewrite elf_i386_get_synthetic_symtab to check PLT sections against all dynamic relocations to support both lazy and non-lazy PLTs. bfd/ * elf32-i386.c (PLT_ENTRY_SIZE): Renamed to ...

2017-01-02Run more ld tests when not nativeAlan Modra2-42/+23
Many of the ld tests are not run for cross builds, in some cases because the test needs to run a newly linked executable, and in others simply because it was easier to write the test for native only. Even when a test needs to run, it's good to compile and link to exercise the linker. So that's what this patch does. I've also rid us of the old ld_link procedure with all the HOSTING_CRT0 etc. setup. It's much simpler to just link with $CC. This does mean that a cross build with cross-compiler installed but no cross C-library will give lots of failures. If that turns out to be too annoying, I guess we can write a tcl procedure to detect it and not run all the extra tests. * Makefile.am (bootstrap): Delete rule.

2016-08-29i386: Issue an error on non-PIC call to IFUNC in PIC objectH.J. Lu8-72/+4
On i386, IFUNC function must be called via PLT. Since PLT in PIC object uses EBX register, R_386_PLT32 relocation must be used to call IFUNC function even when IFUNC function is defined locally. Linker should issue an error when R_386_PC32 relocation is used to call IFUNC function.

2016-02-26Optimize x86 GOT32X/GOTPCRELX relocationsH.J. Lu4-4/+28
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.

2016-01-01Copyright update for binutilsAlan Modra2-2/+2
2015-10-22Add R_X86_64_[REX_]GOTPCRELX support to gas and ldH.J. Lu1-1/+1
This patch adds support for the R_X86_64_GOTPCRELX and R_X86_64_REX_GOTPCRELX relocations proposed in https://groups.google.com/forum/#!topic/x86-64-abi/n9AWHogmVY0 to gas and ld. It updates gas to generate R_X86_64_GOTPCRELX, R_X86_64_REX_GOTPCRELX if there is a REX prefix, relocation for memory operand, foo@GOTPCREL(%rip). With the locally defined symbol, foo, we convert mov foo@GOTPCREL(%rip), %reg to lea foo(%rip), %reg and convert call/jmp *foo@GOTPCREL(%rip) to nop call foo/jmp foo nop When PIC is false, convert test %reg, foo@GOTPCREL(%rip) to test $foo, %reg and convert binop foo@GOTPCREL(%rip), %reg to binop $foo, %reg where binop is one of adc, add, and, cmp, or, sbb, sub, xor instructions. bfd/ * elf64-x86-64.c: Include opcode/i386.h.
