| Subject: sparc32: Add -Av8 to assembler command line. |
| |
| From: "David S. Miller" <davem@davemloft.net> |
| |
| commit e0adb9902fb338a9fe634c3c2a3e474075c733ba upstream. |
| |
| Newer version of binutils are more strict about specifying the |
| correct options to enable certain classes of instructions. |
| |
| The sparc32 build is done for v7 in order to support sun4c systems |
| which lack hardware integer multiply and divide instructions. |
| |
| So we have to pass -Av8 when building the assembler routines that |
| use these instructions and get patched into the kernel when we find |
| out that we have a v8 capable cpu. |
