| * strip: Deal with ARM data marker symbols pointing to debug sections.Mark Wielaard2017-07-241-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ARM data marker symbols "$d" indicate the start of a sequence of data items in a section. For data only sections no data marker symbol is necessary, but may be put pointing to the start of the section. binutils however has a bug which places a data marker symbol somewhere inside the section (at least for .debug_frame). https://sourceware.org/bugzilla/show_bug.cgi?id=21809 When strip finds a symbol pointing to a debug section that would be put into the .debug file then it will copy over the whole symbol table. This isn't necessary because the symbol is redundant. Add an ebl hook to recognize data marker symbols with implementations for arm and aarch64. Use it in strip to strip such symbols from the symbol table if they point to a debug section. Signed-off-by: Mark Wielaard <[email protected]>
* | Generalize library namesUlf Hermann2017-04-281-0/+2
| | | | | | | | | | | | | | | | | | On windows library names end with ".dll" and the prefix "lib" us usually omitted. Take this into account and also drop the $(EXEEXT) workaround. We don't need to use noinst_PROGRAMS as there is also noinst_DATA. Change-Id: I7e4ba2432811d5ad85051ea0c9d5674eabf79b3c Reviewed-by: Christian Kandeler <[email protected]>
* | Check for -z,defs, -z,relro, -fPIC, -fPIE before using themUlf Hermann2017-04-281-1/+1
|/ | | | | | | | | On windows those aren't needed because the link results are no ELF files and all code is position independent anyway. gcc then complains about them, which is in turn caught by -Werror.

* dwelf: Add string table functions from ebl.Mark Wielaard2016-08-031-1/+1
| | | | | | | | | | | | | | | | Move the strtab functions from libebl to libdw. Programs often want to create ELF/DWARF string tables. We don't want (static) linking against ebl since those are internal functions that might change. This introduces dwelf_strtab_init, dwelf_strtab_add, dwelf_strtab_add_len, dwelf_strtab_finalize, dwelf_strent_off, dwelf_strent_str and dwelf_strtab_free. Documentation for each has been added to libdwelf.h. The add fucntion got a variant that takes the length explicitly and finalize was changed to return NULL on out of memory instead of aborting. All code and tests now uses the new functions. Signed-off-by: Mark Wielaard <[email protected]>
* Remove eu-ld and unused code.Mark Wielaard2016-08-031-4/+2
| | | | | | | | Nobody has hacked on eu-ld in a very long time. It didn't really work. And we didn't install it by default in the spec file. Remove sources, the build rules and any (now) unused code. Signed-off-by: Mark Wielaard <[email protected]>
* Use -fPIC instead of -fpic when generating PIC code.Jose E. Marchesi2015-10-061-1/+1
| | | | | | | This avoids relocation overflows in sparc/sparc64 targets while linking, where the reachable data using -fpic is only 4kb. Signed-off-by: Jose E. Marchesi <[email protected]>
* backends: Add ebl_check_reloc_target_type.Mark Wielaard2014-05-191-1/+1
| | | | | | | | | And implement for arm and ia64. Both have special section types that are valid targets for a reloc. Both refer to unwind data. elflint now just calls ebl_check_reloc_target_type instead of hard coding the expected section types. Signed-off-by: Mark Wielaard <[email protected]>
* libdwfl: Introduce dwfl_module_getsym_info and dwfl_module_addrinfo.Mark Wielaard2013-12-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some arches like ppc64 use function descriptor values instead of function addresses causing matching of names and addresses to fail when using dwfl_module_getsym or dwfl_module_addrsym. Add ebl hook to resolve any function descriptor values found in non-ET_REL modules. The new function dwfl_module_getsym_info doesn't adjust the symbol value in any way, but returns the adjusted and/or resolved address associated with the symbol separately. The new function dwfl_module_addrinfo resolves against both the address associated with the symbol (which could be the function entry address) value and the adjusted st_value. So that it is easy to resolve and match either function descriptors and/or function entry addresses. Since these new functions also return more information they replace the dwfl_module_getsym_elf and dwfl_module_addrsym_elf functions that never made it into a released elfutils version. addr2line and readelf now use the new functions when looking up functions names. addr2line will now also display the section the address was found in when given -x. Extra testcases were added for both addr2line and the dwflsyms testscase. Signed-off-by: Mark Wielaard <[email protected]>
