The comparison engine doesn't take virtual offset changes into account
when deciding if a diff node carries an incompatible change. This is
obviously an oversight.
Fixed thus.
* include/abg-comparison.h (enum diff_category): Adjust the
comment for enumerator VIRTUAL_MEMBER_CHANGE_CATEGORY; changes of
this category are incompatible ABI changes.
(corpus_diff::diff_stats::num_func_with_virtual_offset_changes):
Declare new accessors.
* src/abg-comparison.cc
(corpus_diff::diff_stats::priv::num_func_with_virt_offset_changes):
New data member.
(corpus_diff::diff_stats::priv::priv): Initialize the new data
member.
(corpus_diff::diff_stats::num_func_with_virtual_offset_changes):
Define new accessors.
(corpus_diff::priv::apply_filters_and_compute_diff_stats): Use the
new accessor to set the number of functions with virtual offset
changes onto the stats data structure.
(corpus_diff::has_incompatible_changes): Take functions with
virtual offset changes into account.
* tests/test-abidiff-exit.cc: New test harness to test for exit
codes of abidiff.
* tests/Makefile.am: Build the new test harness runtestabidiff
from the test-abidiff-exit.cc source file.
* tests/data/test-abidiff-exit/test1-voffset-change-report0.txt:
New reference test output.
* tests/data/test-abidiff-exit/test1-voffset-change-v0.cc: New
test input source code.
* tests/data/test-abidiff-exit/test1-voffset-change-v0.o: New test input.
* tests/data/test-abidiff-exit/test1-voffset-change-v1.cc: New
test input source code.
* tests/data/test-abidiff-exit/test1-voffset-change-v1.o: New test input.
* tests/data/Makefile.am: tests/data/Makefile.am: Add the new test
inputs above to the source distribution.
