            Bug ID: 112563
           Summary: [14 regression] libsanitizer doesn't assemble with
                    Solaris/sparc as
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: sanitizer
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---
              Host: sparc-sun-solaris2.11
            Target: sparc-sun-solaris2.11
             Build: sparc-sun-solaris2.11

The recent libsanitizer import broke bootstrap with the native Solaris/sparc
as:

/usr/ccs/bin/as: ".libs/sanitizer_errno.s", line 4247: error: symbol
"__sanitizer_internal_memset" is used but not defined
/usr/ccs/bin/as: ".libs/sanitizer_errno.s", line 4247: error: symbol
"__sanitizer_internal_memcpy" is used but not defined
/usr/ccs/bin/as: ".libs/sanitizer_errno.s", line 4247: error: symbol
"__sanitizer_internal_memmove" is used but not defined

make[4]: *** [Makefile:623: sanitizer_errno.lo] Error 1

The code in question is

        memcpy =3D __sanitizer_internal_memcpy
        memmove =3D __sanitizer_internal_memmove
        memset =3D __sanitizer_internal_memset

which is from libsanitizer/sanitizer_common/sanitizer_redefine_builtins.h.

I'm currently continuing the build with that hack disabled on Solaris/sparc
(it isn't easy to distinguish between as and gas toolchains here).=
