Sinny Kumari reported that abicompat is failing to report ABI changes
on a library linked to a small test program. It turned out that the
code that compute if a given exported function is to be kept by
looking at the white list of symbols to keep has a bug in which the
versions of the symbols of the white list were not being reset as they
should. Fixed thus.
* src/abg-ir.cc (elf_symbol::get_name_and_version_from_id): Always
set the version and name of the symbol.
* src/abg-corpus.cc
(corpus::exported_decls_builder::{keep_wrt_id_of_fns_to_keep,
keep_wrt_id_of_vars_to_keep}): Reset the symbol name *and* version
before passing it. This is redundant with the fix in
elf_symbol::get_name_and_version_from_id() that always set the
symbol name and version now, but I felt it makes it easier to
understand the fix overall.
* tests/data/test-abicompat/libtest7-fn-changed-libapp-v{0,1}.so:
New test input binaries.
* tests/data/test-abicompat/test7-fn-changed-app: Likewise.
* tests/data/test-abicompat/test7-fn-changed-{app, libapp-v0,
libapp-v1}.c: Source code of the binary test inputs above.
* * tests/data/test-abicompat/test7-fn-changed-{libapp-v0,
libapp-v1}.h: Likewise.
* tests/data/test-abicompat/test7-fn-changed-report-0.txt: Test
input.
* tests/data/Makefile.am: Add the new test material above to
source distribution.
* tests/test-abicompat.cc (int_out_specs): Add the test inputs
above to the set of inputs this test harness has to run over.
