GCC can generate several DW_TAG_unspecified_parameters for a given function. Abigail's DWARF reader is recklessly creating a variadic function parameter in its internal representation (IR) each time it sees a DW_TAG_unspecified_parameters. This leads to functions having several variadic parameters in the final IR. And this is wrong. This patch fixes the problem by creating a variadic parameter only for the first DW_TAG_unspecified_parameters encountered for a given function DIE. * src/abg-dwarf-reader.cc (build_function_type): Create a variadic parameter just for the first DW_TAG_unspecified_parameters seen. * tests/data/test-diff-filter/test30-pr18904-rvalueref-report0.txt: Adjust. * tests/data/test-diff-filter/test30-pr18904-rvalueref-report1.txt: Adjust. * tests/data/test-read-dwarf/test16-pr18904.so.abi: Adjust.
