The test run-strip-strmerge.sh is failing in sparc targets. This is because it does an `elflint -d' in a debuginfo file, and this fails with: section [21] '.plt' is both executable and writable elflint uses the ebl_check_special_section hook (implemented only by the alpha and sparc backends) in order to determine whether an executable+writable section must be flagged or not. In both cases the hook will fail analyzing eu-strip debuginfo files (as they should, because debuginfo files are broken ;). This patch just modifies elflint to not use the hook when -d is specified in the command-line. This fixes the test in sparc-* and sparc64-* targets (and presumably in alpha* targets too). Additionaly, the patch checks that the type of WE sections in debuginfo files is NOBITS. Signed-off-by: Jose E. Marchesi <jose.marchesi@oracle.com>
Fundamental design decision: - the sizes of external and internal types are assumed to be the same. This leaves byte ordering aside. While assuming this the code can be greatly simplified and speed increases. Since no change violating this assumption is in sight this is believed to be a worthwhile optimization. - the ABI of the backend modules is not guaranteed. Really, no guarantee whatsoever. We are enforcing this in the code. The modules and their users must match. No third-party EBL module are supported or allowed. The only reason there are separate modules is to not have the code for all architectures in all the binaries. - although the public libraries (libasm, libdw) have a stable API and are backwards ABI compatible they, and the elfutils tools, do depend on each others internals, and on internals of libelf to provide their interfaces. So they should always be upgraded in lockstep when packaging the tools and libraries separately. For one example of how to do that, see the config/elfutils.spec.
