[Bug 262706] Build on arm64 fails to find libclang_rt.asan-aarch64.a
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=262706 --- Comment #20 from Dimitry Andric --- (In reply to feh from comment #19) It looks rather different: this bug was originally about aarch64 not supporting some (or all) of the sanitizers. Later, it became about some refactoring in the Makefiles causing libraries for some architectures to be erroneously skipped. In your case, it looks like you used freebsd-update? And maybe it was not aware that you had the /usr/lib/clang directory at all, so it did not update it? How did you upgrade, exactly? -- You are receiving this mail because: You are the assignee for the bug.

`_aarch64_ctx` is a Linux-specific context struct from
/usr/include/aarch64-linux-gnu/asm/sigcontext.h:
/*
* Header to be used at the beginning of structures extending the user
* context. Such structures must be placed after the rt_sigframe on the stack
* and be 16-byte aligned. The last structure must be a dummy one with the
* magic and size set to 0.
*/
struct _aarch64_ctx {
__u32 magic;
__u32 size;
};
but obviously it doesn't exist in FreeBSD. Similarly, struct ucontext and
mcontext have different members, and aren't generally compatible.
I think the only way to get this implemented is to have somebody with aarch64
knowledge, who can attempt to fix them up and submit reviews upstream.
