tests: Don't match libfunc symbol on ppc64 in run-deleted.sh testcase.

2014-12-19T19:53:22+00:00

For PPC64 we need access to the OPD table which we get through the shdrs
but for the deleted-lib we only have phdrs.  So we don't have the name of
the function. But since we should find the EH_FRAME through phdrs just
fine, we can unwind into main. Skip the libfunc name check for now till
we find a nice way to enable the lookup without opd:

tests: vdsosyms should not fail for architectures that don't have a vdso.

2014-12-19T17:54:04+00:00

Not finding a vdso is not fatal. But there should be no errors trying.
And if the vdso is found, then getting the symbol table shouldn't fail.

tests: run-deleted.sh should SKIP if arch doesn't support unwinding.

Also relax the special ARM needs DWARF check a little to account for eu-stack
error output.

libdwfl: Always try find_dynsym last, also on find_symtab ELF errors.

2014-12-19T17:19:29+00:00

An ELF error during find_symtab might be incomplete shdrs or string table
from ELF images read through elf_from_memory. The phdrs and dynsym should
always be complete.

libdwfl: Remove p_align sanity check from elf_from_memory.

2014-12-19T17:07:38+00:00

In commit f15bcd "elf_from_remote_memory should use pagesize, not p_align"
we already relaxed the p_align sanity check to allow alignment of the
segment against the pagesize since that is what the glibc dynamic linker
actually does. But on some architectures the kernel inserts a vdso with
a completely bogus p_align for some PT_LOAD segments. So just drop the
whole sanity check and allow anything since we won't use p_align, but
always already use pagesize anyway.

avoid scary command output

2014-12-18T22:47:22+00:00

The commands to check for invalid text relocations in the generated DSOs
shouldn't be displayed.  They contain an echo which prints the text.
This patch suppresses the commands from being printed.

Prepare 0.161 release.

readelf: Add bounds check before each CFA op that takes an argument.

2014-12-17T15:49:03+00:00

Some CFA ops don't take any arguments, for those it is valid to be at the
end of the data block.
