| 4 | Subject: [PATCH 16/40] gcc: armv4: pass fix-v4bx to linker to support EABI. |
| 5 | |
| 6 | The LINK_SPEC for linux gets overwritten by linux-eabi.h which |
| 7 | means the value of TARGET_FIX_V4BX_SPEC gets lost and as a result |
| 8 | the option is not passed to linker when chosing march=armv4 |
| 9 | This patch redefines this in linux-eabi.h and reinserts it |
| 10 | for eabi defaulting toolchains. |
| 11 | |
| 12 | We might want to send it upstream. |
