2022-07-08	selftests/bpf: Add test involving restrict type qualifier	Daniel Müller	1	-0/+5
	This change adds a type based test involving the restrict type qualifier to the BPF selftests. On the btfgen path, this will verify that bpftool correctly handles the corresponding RESTRICT BTF kind.

2022-07-05	selftests/bpf: Add nested type to type based tests	Daniel Müller	1	-0/+12
	This change extends the type based tests with another struct type (in addition to a_struct) to check relocations against: a_complex_struct. This type is nested more deeply to provide additional coverage of certain paths in the type match logic.

2022-07-05	selftests/bpf: Add type-match checks to type-based tests	Daniel Müller	1	-1/+31
	Now that we have type-match logic in both libbpf and the kernel, this change adjusts the existing BPF self tests to check this functionality. Specifically, we extend the existing type-based tests to check the previously introduced bpf_core_type_matches macro.

2020-08-19	selftests/bpf: Add CO-RE relo test for TYPE_ID_LOCAL/TYPE_ID_TARGET	Andrii Nakryiko	1	-14/+0
	Add tests for BTF type ID relocations. To allow testing this, enhance core_relo.c test runner to allow dynamic initialization of test inputs. If Clang doesn't have necessary support for new functionality, test is skipped.

2020-08-19	selftests/bpf: Test TYPE_EXISTS and TYPE_SIZE CO-RE relocations	Andrii Nakryiko	1	-0/+124
	Add selftests for TYPE_EXISTS and TYPE_SIZE relocations, testing correctness of relocations and handling of type compatiblity/incompatibility. If __builtin_preserve_type_info() is not supported by compiler, skip tests.
