With PR #107223 and PR #107403, ASan testing can be enabled on SPARC. This patch does so, 32-bit only on both Solaris and Linux. There is no 64-bit support even in GCC. Apart from the obvious CMake changes, this patch includes a couple of testcase adjustments necessary for SPARC: - In `asan_oob_test.cpp`, the `OOB_int` subtest needs to be disabled: it performs unaligned accesses that cannot work on a strict-alignment target like SPARC. - `asan_test.cpp` needs to disable subtests that depend on support for `__builtin_setjmp` and `__builtin_longjmp`. - `zero_page_pc.cpp` reports `0x5` as the faulting address on access to `0x4`. I don't really know why, but it's consistent between Solaris and Linux. Tested on `sparcv9-sun-solaris2.11` and `sparc64-unknown-linux-gnu`.
