--- Comment #2 from Manjunath S Matti <mmatti at linux dot vnet.ibm.com> ---
If glibc is configured without 'CFLAGS=3D-O2 -mcpu=3Dpower9', i.e.

$ ./configure --prefix=3D/usr --with-headers=3D/usr/include --build=3Dppc64=
le-linux
--with-cpu=3Dpower10

$ make=20

This successfully builds glibc. Comparing the pass case with the fail case =
of
acct.os we get=20

     5c:  08 00 00 48     b       64 <__GI_acct+0x64>
   60:  20 00 e3 4c     bnslr+
   64:  00 00 00 48     b       64 <__GI_acct+0x64>
-                       64: R_PPC64_REL24_NOTOC __syscall_error
+                       64: R_PPC64_REL24       __syscall_error
        ...
   70:  40 20 0c 00     .long 0xc2040
   74:  68 00 00 00     .long 0x68


The build goes through because R_PPC64_REL24_NOTOC is generated.

--=20
