Hi, I have been looking at enabling libsanitizer for aarch64 GCC compilers.
To make the build succeed, I had to modify libsanitizer code: - some syscalls are not available on aarch64 (libsanitizer uses some legacy ones such as open, readlink, stat, ...) - unwinding code needs to be added. What's the way of discussing such patches? On GCC lists or elsewhere? Then arises a runtime problem: aarch64's frame grows upward which is not supported: how long would it take to develop this support if at all possible? I have not looked at tsan in detail yet, it currently does not build for aarch64 either. Thanks, Christophe.
