| 4 | Subject: [PATCH] mpn/arm/udiv.asm: workaround binutils bug #14887 |
| 5 | |
| 6 | Old binutils versions are affected by bug #14887, |
| 7 | https://sourceware.org/bugzilla/show_bug.cgi?id=14887, which causes a |
| 8 | build failure when a register specification is surrounded by |
| 9 | whitespaces. Removing those whitespaces works around the issue. |
