            Bug ID: 98437
           Summary: confusing wording in the description of option
                    -fsanitize=address
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: other
          Assignee: unassigned at gcc dot gnu.org
          Reporter: linkw at gcc dot gnu.org
  Target Milestone: ---

As Qingnan's question[1] in the mail list gcc-help, the last part in the
current description of option -fsanitize=address looks confusing. Manual users
are easy to misunderstand the below wording

   "Note that the only target this option is currently supported on is
AArch64." 

is specific for option -fsanitize=address.  But it's intended to note the
option -fsanitize=hwaddress which can not be combined with option
-fsanitize=address.

Both hook TARGET_MEMTAG_CAN_TAG_ADDRESSES and commit r11-5375 shows only option
-fsanitize=hwaddress is aarch64 specific.

    docs: Fix wording describing the hwaddress sanitizer

    The original documentation added to mention the clash between
    -fsanitize=address and -fsanitize=hwaddress used confusing wording trying
    to say that -fsanitize=hwaddress is only available on AArch64.

    It read as if -fsanitize=address were only supported on AArch64.

    This patch fixes that wording by being more explicit.

    gcc/ChangeLog:

            clash with -fsanitize=hwaddress.
