2018-02-06Fix GCC 8's -Wstringop-overflow on bfd/coff-rs6000.cSergio Durigan Junior2-1/+6
GCC 8 will bring a new warning option which will detect possible overflow and truncation on string manipulation functions. For more details, see: https://gcc.gnu.org/ml/gcc-patches/2017-08/msg00471.html While compiling BFD with it, I can see one place on bfd/coff-rs6000.c where the warning is triggered. This: (void) strncpy (fhdr.magic, XCOFFARMAG, SXCOFFARMAG); will not include the trailing NUL on fhdr.magic, but that's fine because it's a magic number. The fix is trivial: just use memcpy instead.

return file and line number information. The nm utility supports -l for using debug information to obtain file and line information for each symbol, if available. We have a tool that consumes this information and displays it. This identified a problem with the 'nm' utility. When a source is compiled with -O2, functions can be inlined. The compiler also produces an uninlined copy of the function, normally for linking to other object files. In the case of DWARF2 debug information, the compiler generates debug information to describe a function. If that function is inlined, the compiler then references that debug information from the inlined and uninlined copies of the routine through the use of the DW_AT_abstract_origin reference. When nm is used on such a file, it is not able to find file and line information because that information is present in the common debug information and not at each actual implementation of the function. The 'nm' utility only retrieves the name of the function from the abstract origin debug information and no more. What I am proposing is to modify the find_abstract_instance_name() function (which I renamed to find_abstract_instance() ) to return the name of the function as well as any file and line information. The routine is already parsing all of the debug information in the abstract instance, so it is easy to pick up the file and line information at that time. If, for some reason, the file and line information is not present, the routine behaves as before. For example, if I have a simple test case: int foo(int j) { if (j < 15) j += j << 2; else j += j << 6; return j; } int main (int argc,char **argv) { int i = argc; i += foo(i); return i; } If that test case is compiled with -O2 and then 'nm -l' reads that executable, it currently produces this symbol output (ignoring a lot of library symbols): 8048400 T foo 080482e0 T main /scratch/pcarroll/its254/test/mytest.c:12 If I modify 'nm' to return file and line information for abstract instances, it produces the following output: 08048400 T foo /scratch/pcarroll/its254/test/mytest.c:1 080482e0 T main /scratch/pcarroll/its254/test/mytest.c:12 -------------------------------------------------------------------------- bfd * bfd/dwarf2.c (find_abstract_name): Modified to return file and line information in addition to name, if they can be found.

This patch fixes a case where a user had a C-representable named section in both the executable and shared libraries, and of course wanted the size of the local section in the executable, not the dynamic section.

2018-01-26PowerPC64 .branch_lt size change leads to "stubs don't match calculated size"Alan Modra2-0/+11
https://bugzilla.redhat.com/show_bug.cgi?id=1523457 I haven't analyzed this myself, I'm relying on Nick's excellent analysis. What I believe is happening is that after some number of stub sizing iterations, a long-branch stub needs to be converted to a plt-branch, but either due to stub alignment or other stubs shrinking in size, the stub group section size doesn't change. That means we exit from ppc64_elf_size_stubs after sizing with an incorrect layout, in fact the additional .branch_lt entry overlays .got! Since .TOC. is normally set to .got + 0x8000 the stub sizing code decides that entry is within +/-32k of the TOC pointer and so a three insn stub is sufficient. When we come to build the stubs using a correct non-overlaying layout, a four insn plt-branch stub is generated and the stub group size doesn't match that calculated earlier. * elf64-ppc.c (ppc64_elf_size_stubs): Iterate sizing when .branch_lt changes size.
