2024-09-26ld: Ignore .note.gnu.build-id when placing orphaned notesH.J. Lu1-0/+1
The commits: e8e10743f7b Add --rosegment option to BFD linker to stop the '-z separate-code' from generating two read-only segments. bf6d7087de0 ld: Move the .note.build-id section to near the start of the memory map place .note.gnu.build-id before text sections when --rosegment is used. Ignore .note.gnu.build-id when placing orphaned notes if --rosegment and -z separate-code are used together to avoid putting any note sections between .note.gnu.build-id and text sections in the same PT_LOAD segment.

2021-04-26x86: correct overflow checking for 16-bit PC-relative relocsJan Beulich1-0/+1
The only insn requiring a truly 16-bit PC-relative relocation outside of 16-bit mode is XBEGIN (with an operand size override). For it, the relocation generated should behave similar to 8- and (for 64-bit) 32-bit PC-relatives ones, i.e. be checked for a signed value to fit the field. This same mode is also correct for 16-bit code. Outside of 16-bit code, branches with operand size overrides act in a truly PC-relative way only when living in the low 32k of address space, as they truncate rIP to 16 bits. This can't be expressed by a PC-relative relocation. Putting in place a new testcase, I'd like to note that the two existing ones (pcrel16 and pcrel16abs) appear to be pretty pointless: They don't expect any error despite supposedly checking for overflow, and in fact there can't possibly be any error for the - former since gas doesn't emit any relocation in the first place there, - latter because the way the relocation gets expressed by gas doesn't allow the linker to notice the overflow; it should be detected by gas if at all, but see above (an error would be reported here for x86-64 afaict, but this test doesn't get re-used there).

2020-10-09x86: Support GNU_PROPERTY_X86_ISA_1_V[234] markerH.J. Lu1-0/+4
GCC 11 supports -march=x86-64-v[234] to enable x86 micro-architecture ISA levels: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97250 Update GNU_PROPERTY_X86_ISA_1_XXX macros: https://gitlab.com/x86-psABIs/x86-64-ABI/-/merge_requests/13 in x86 ELF binaries to indicate that micro-architecture ISA levels required to execute the binary: #define GNU_PROPERTY_X86_ISA_1_NEEDED (GNU_PROPERTY_X86_UINT32_OR_LO + 2) #define GNU_PROPERTY_X86_ISA_1_USED (GNU_PROPERTY_X86_UINT32_OR_AND_LO + 2) #define GNU_PROPERTY_X86_ISA_1_V2 (1U << 0) #define GNU_PROPERTY_X86_ISA_1_V3 (1U << 1) #define GNU_PROPERTY_X86_ISA_1_V4 (1U << 2) The previous GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed to GNU_PROPERTY_X86_COMPAT_2_ISA_1_XXX. In addition to EM_X86_64, GNU_PROPERTY_X86_ISA_1_V[234] marker can be used by ld.so to detect the x86-64-v4 shared library placed in an x86-64-v2 directory by mistake on an x86-64-v2 machine to avoid crashes on x86-64-v4 instructions. Add -z x86-64-v[234] linker command line option to mark x86-64-v[234] ISA level as needed. Also add #define GNU_PROPERTY_X86_FEATURE_2_MASK (1U << 11) for mask registers. bfd/ PR gas/26703 * elf-linker-x86.h (elf_linker_x86_params): Add isa_level. * elfxx-x86.c (_bfd_x86_elf_merge_gnu_properties): Merge GNU_PROPERTY_X86_ISA_1_V[234].

2020-06-20Remove perror from ld_assemble, ld_compile and ld_nmAlan Modra1-4/+4
ERROR should really be reserved for errors in the testsuite framework, not just normal errors from the tools under test. Removing use of perror has been suggested before but without action, over concerns that some test failures might be missed. This patch removes uses of perror in ld_assemble, ld_compile and ld_nm, and updates numerous places that ignored the result of these functions by inappropriately returning an "unresolved" test status. Net result over my large set of targets look good, in some cases improving the diagnostics, eg: i386-msdos -ERROR: tmpdir/script: nm failed i386-msdos -ERROR: tmpdir/script: nm failed i386-msdos -ERROR: tmpdir/script: nm failed i386-msdos -ERROR: tmpdir/script: nm failed i386-msdos +FAIL: script i386-msdos +FAIL: MRI script i386-msdos +FAIL: MEMORY i386-msdos +FAIL: MEMORY with symbols * testsuite/lib/ld-lib.exp (default_ld_compile): Don't perror on a compiler error.

2019-04-24Use better test for usable compiler in ld testsuite.Sandra Loosemore1-3/+3
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.
