Hi everyone,
I was looking at this page Instrumentation Options (Using the GNU Compiler Collection (GCC))<https://gcc.gnu.org/onlinedocs/gcc/Instrumentation-Options.html> and it says "-fsanitize=address" is only supported on AArch64. However, I was able to compile my code on x86-64 CPU with -fsanitize=address flag.
Is the document out-of-date? Or, does it mean the result of ASan is not guaranteed on any platform other than AArch64?
Thanks in advance for your help!
Best regards,
Qingnan Duan

I think the part "Note that the only target this option is currently supported on is AArch64. "
is specific for option “-fsanitize=hwaddress” not for option "-fsanitize=address".
Only aarch64 port re-defines TARGET_MEMTAG_CAN_TAG_ADDRESSES which is used for -fsanitize=hwaddress,
that matches the wordings.
By the way, I also felt a bit confused without digging, not sure whether it's confusing from
native speaker's perspective. If yes, maybe it's worth to revise it somehow. :)

Yes, the documentation should be fixed. As currently written it's incorrect.
Could you please file a bug?
