* Handle ADD/SUB relocationsAndreas Schwab2018-10-131-1/+25
| | | | | | This adds support for ADD and SUB relocations as seen on RISC-V. Signed-off-by: Andreas Schwab <schwab@suse.de>
* backends: Always use elf_getshdrstrndx in check_special_symbol.Mark Wielaard2018-09-131-2/+5
| | | | | | | | | | The check_special_symbol backend functions used the Ehdr e_shstrndx field to get at the name of sections. This is not correct if there are more than SHN_LORESERVE sections. Always use elf_getshdrstrndx to get the shstrtab section. And drop the Ehdr argument that isn't necessary anymore. Signed-off-by: Mark Wielaard <mark@klomp.org>

* Add support for RISC-VAndreas Schwab2018-04-231-0/+62
This implements initial support for the RISC-V architecture. It has been tested with qemu linux-user emulation <https://build.opensuse.org/package/live_build_log/openSUSE:Factory:RISCV/elfutils/standard/riscv64>, with the following unresolved issues FAIL: run-strip-strmerge.sh =========================== elflint /home/abuild/rpmbuild/BUILD/elfutils-0.170/tests/elfstrmerge section [32] '.symtab': _GLOBAL_OFFSET_TABLE_ symbol value 0x51c0 does not match .got section address 0x5010 section [32] '.symtab': symbol 119: st_value out of bounds FAIL run-strip-strmerge.sh (exit status: 1) FAIL: run-elflint-self.sh ========================= section [33] '.symtab': _GLOBAL_OFFSET_TABLE_ symbol value 0x6220 does not match .got section address 0x6008 section [33] '.symtab': symbol 135: st_value out of bounds *** failure in /home/abuild/rpmbuild/BUILD/elfutils-0.170/src/elflint --quiet --gnu-ld /home/abuild/rpmbuild/BUILD/elfutils-0.170/src/addr2line section [33] '.symtab': _GLOBAL_OFFSET_TABLE_ symbol value 0x91d8 does not match .got section address 0x9040 section [33] '.symtab': symbol 163: st_value out of bounds *** failure in /home/abuild/rpmbuild/BUILD/elfutils-0.170/src/elflint --quiet --gnu-ld /home/abuild/rpmbuild/BUILD/elfutils-0.170/src/elfcmp section [33] '.symtab': _GLOBAL_OFFSET_TABLE_ symbol value 0x1a2a0 does not match .got section address 0x1a040 section [33] '.symtab': symbol 267: st_value out of bounds *** failure in /home/abuild/rpmbuild/BUILD/elfutils-0.170/src/elflint --quiet --gnu-ld /home/abuild/rpmbuild/BUILD/elfutils-0.170/src/elflint section [33] '.symtab': _GLOBAL_OFFSET_TABLE_ symbol value 0xd418 does not match .got section address 0xd0f0 section [33] '.symtab': symbol 238: st_value out of bounds *** failure in /home/abuild/rpmbuild/BUILD/elfutils-0.170/src/elflint --quiet --gnu-ld /home/abuild/rpmbuild/BUILD/elfutils-0.170/src/nm section [33] '.symtab': _GLOBAL_OFFSET_TABLE_ symbol value 0xa2d0 does not match .got section address 0xa0b0 section [33] '.symtab': symbol 193: st_value out of bounds *** failure in /home/abuild/rpmbuild/BUILD/elfutils-0.170/src/elflint --quiet --gnu-ld /home/abuild/rpmbuild/BUILD/elfutils-0.170/src/objdump section [33] '.symtab': _GLOBAL_OFFSET_TABLE_ symbol value 0x2e5b8 does not match .got section address 0x2e058 section [33] '.symtab': symbol 410: st_value out of bounds *** failure in /home/abuild/rpmbuild/BUILD/elfutils-0.170/src/elflint --quiet --gnu-ld /home/abuild/rpmbuild/BUILD/elfutils-0.170/src/readelf section [32] '.symtab': _GLOBAL_OFFSET_TABLE_ symbol value 0x171b8 does not match .got section address 0x17010 *** failure in /home/abuild/rpmbuild/BUILD/elfutils-0.170/src/elflint --quiet --gnu-ld /home/abuild/rpmbuild/BUILD/elfutils-0.170/libelf/libelf.so section [32] '.symtab': _GLOBAL_OFFSET_TABLE_ symbol value 0x3a5b0 does not match .got section address 0x3a0d8 *** failure in /home/abuild/rpmbuild/BUILD/elfutils-0.170/src/elflint --quiet --gnu-ld /home/abuild/rpmbuild/BUILD/elfutils-0.170/libdw/libdw.so section [31] '.symtab': _GLOBAL_OFFSET_TABLE_ symbol value 0xd0c8 does not match .got section address 0xd008 *** failure in /home/abuild/rpmbuild/BUILD/elfutils-0.170/src/elflint --quiet --gnu-ld /home/abuild/rpmbuild/BUILD/elfutils-0.170/backends/libebl_i386.so section [31] '.symtab': _GLOBAL_OFFSET_TABLE_ symbol value 0xf0c8 does not match .got section address 0xf008 *** failure in /home/abuild/rpmbuild/BUILD/elfutils-0.170/src/elflint --quiet --gnu-ld /home/abuild/rpmbuild/BUILD/elfutils-0.170/backends/libebl_x86_64.so FAIL run-elflint-self.sh (exit status: 1) FAIL: run-native-test.sh ======================== /home/abuild/rpmbuild/BUILD/elfutils-0.170/tests/allregs: dwfl_module_register_names: no backend registers known FAIL run-native-test.sh (exit status: 1) FAIL: run-backtrace-native-core.sh ================================== backtrace: backtrace.c:111: callback_verify: Assertion `symname && strcmp (symname, "raise") == 0' failed. ./test-subr.sh: line 84: 26040 Aborted (core dumped) LD_LIBRARY_PATH="${built_library_path}${LD_LIBRARY_PATH:+:}$LD_LIBRARY_PATH" $VALGRIND_CMD "$@" backtrace-child-core.26027: no main rmdir: failed to remove 'test-26016': Directory not empty FAIL run-backtrace-native-core.sh (exit status: 1) In addition, all tests that use ptrace are failing as linux-user emulation does not implement it.
