* Use -Wformat=2 by default for all files.Mark Wielaard2014-01-303-9/+34
| | | | | | | | This just makes sure that all format strings are given as literals to printf like functions so the compiler can see and check them. Remove all no_Wformat, add -Wformat=2 unconditionally to AM_CFLAGS. Signed-off-by: Mark Wielaard <mjw@redhat.com>

* backends: Add PPC64 machine_flag_check.Mark Wielaard2014-01-043-2/+18
| | | | | | | | | | To distinguish between the current PPC64 ELF ABI and the revised ELFv2 ABI that will not use function descriptors binutils started to emit the version (currently 1) in the ehdr e_flags. Recognize all valid versions (0, 1 or 2) in elflint by adding the hook ppc64_machine_flag_check. Signed-off-by: Mark Wielaard <mjw@redhat.com>

| | | | | | | | Setup initial CIE values for aarch64 for use with dwarf_frame functions. Register info prefix should be the empty string (not NULL) when not used. Add an EM_AARCH64 testcase to tests/run-addrcfi.sh to check both issues. Signed-off-by: Mark Wielaard <mjw@redhat.com>
* backends: aarch64 always has _GLOBAL_OFFSET_TABLE_ point to .got[0].Mark Wielaard2013-12-203-0/+34
| | | | | | | | | | | Like some other architectures aarch64 has a special rule for the _GLOBAL_OFFSET_TABLE_ symbol. Even if there is a .plt.got section the symbol value still points to the start of the .got section. This is also what the dynamic linker expects. See https://sourceware.org/ml/libc-ports/2013-06/msg00057.html Signed-off-by: Mark Wielaard <mjw@redhat.com>
* libdwfl: Introduce dwfl_module_getsym_info and dwfl_module_addrinfo.Mark Wielaard2013-12-204-1/+101
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <mjw@redhat.com>

* backends: ppc_abi_cfi reg1 use DW_CFA_val_offset not DW_CFA_val_expression.Mark Wielaard2013-10-072-1/+6
| | | | | | | | | | | | | | | Register rules using expressions are stored using an offset from the start of the .eh_frame or .debug_frame ELF section data. Since abi_cfi rules aren't stored in those ELF sections they should use neither DW_CFA_expression nor DW_CFA_val_expression. The only backend that used DW_CFA_val_expression was ppc_cfi.c. It was easier to express the same rule using DW_CFA_val_offset than to change the code to handle register rules using expressions. On most architectures this did work by accident. See the definition of struct dwarf_frame_register value in libdw/cfi.h to see why. But on ia64 the abi_cfi data and actual frame data were placed too far apart and caused a crash in tests/run-addrcfi.sh for ppc32. Signed-off-by: Mark Wielaard <mjw@redhat.com>
* backends: Hook abi_cfi for arm.Mark Wielaard2013-09-034-2/+96
| | | | | | | | | | | | | | | | | | | | | | New arm_abi_cfi that defines initial CFA, rules for callee-saved regs, including VFP ones and return register. Note the DWARF abi extension for ARM says that "registers intentionally unused" should also be initialized as if by DW_CFA_same_value. The example given is "an integer-only function might be included in one executable file for targets with VFP and another for targets without". We don't currently do this yet. See the DWARF and calling convention documents: DWARF for the ARM Architecture ABI r2.09 http://infocenter.arm.com/help/topic/com.arm.doc.ihi0040b/IHI0040B_aadwarf.pdf Procedure Call Standard for the ARM Architecture ABI r2.09 http://infocenter.arm.com/help/topic/com.arm.doc.ihi0042e/IHI0042E_aapcs.pdf Also adds addrcfi arm testcase.

* backends: Always set *prefix to "" when not used in register_info hook.Mark Wielaard2013-09-024-3/+9
| | | | | | | | | | | | For ia64 and tilegx *prefix was already set to the empty string, but arm, ppc and sh used NULL to indicate no prefix preceded the register name in the canonical assembler syntax. Consistently use the empty string in all backends since dwfl_module_register_names says: 'a prefix used in assembler syntax (such as "%" or "$", may be "")'. So users had to handle the empty string already, and might forget to handle the NULL case (like our own addrcfi testcase). Signed-off-by: Mark Wielaard <mjw@redhat.com>
* Updates for Automake 1.13.Mark Wielaard2013-04-262-1/+5
| | | | | | | autoreconf will install config/test-driver, ignore it. Update gettext m4 and po files to version 0.18.2. Use AM_CPPFLAGS instead of INCLUDES. All changes are backward compatible with Automake 1.11.
* backends: Check type DIE exists before calling dwarf_tag ().Mark Wielaard2013-02-0613-36/+59
| | | | | | | | | | | | | dwarf_attr () or dwarf_form () functions leave typedie NULL when they fail because of missing attribute or unexpected form. In such cases first check the DIE exists and return error instead of calling dwarf_tag () and crashing. This also happens in the testsuite with native tests when elfutils is build without DWZ support on a distro that uses DWZ DWARF compression on system libraries. Only the backends used dwarf_tag () directly without checking, all other uses in elfutils already checked whether the given DIE was NULL. Signed-off-by: Mark Wielaard <mjw@redhat.com>
