Libabigail fails to to synthesize a non-existing pointer type to an existing type. This makes abicompat fail in weak mode when trying to detect changes to a function type where the parameter is a pointer to a structure which changed. In the application, the function is invoked and a pointer to the structure is passed to it. It appears that the type of structure is defined in the debug info of the application, but not the pointer to that structure. So abicompat needs to synthesize that pointer to struct in order to synthesize the type of the function, and so, compare it to the type of the function coming from the library. It appears that synthesizing a pointer type (to an existing type) is not supported. Only synthesizing qualified type was supported. This patch adds support for that and thus fixes the abicompat test case that is attached. * include/abg-ir.h: Update copyright. * src/abg-ir.cc (synthesize_type_from_translation_unit): Support synthesizing pointer types. * tests/data/test-abicompat/libtest8-fn-changed-libapp-v0.so: New test input. * tests/data/test-abicompat/libtest8-fn-changed-libapp-v1.so: Likewise. * tests/data/test-abicompat/test8-fn-changed-app: Likewise. * tests/data/test-abicompat/test8-fn-changed-app.c: Likewise. * tests/data/test-abicompat/test8-fn-changed-libapp-v0.c: Likewise. * tests/data/test-abicompat/test8-fn-changed-libapp-v0.h: Likewise. * tests/data/test-abicompat/test8-fn-changed-libapp-v1.c: Likewise. * tests/data/test-abicompat/test8-fn-changed-libapp-v1.h: Likewise. * tests/data/test-abicompat/test8-fn-changed-report-0.txt: Likewise. * tests/data/Makefile.am: Add the new test input files to source distribution. * tests/test-abicompat.cc (in_out_specs): Add the new test inputs above to the test harness.
