| Subject: [PATCH] Makefile.arm: remove -march flags |
| |
| The provided -march flags, especially for ARMv5 and ARMv6 may not |
| necessarily match the needed ones: for ARMv5, it might be armv5, |
| armv5te, armv5t, etc. If the wrong one is used, the incorrect toolchain |
| sysroot can be used in a multilib toolchain. |
| |
| Therefore, let the user building OpenBLAS pass the appropriate -march |
| flag. |
| |
| The other flags, such as -mfpu=vfp or -mfloat-abi=hard are kept, as they |
| are actually required for the build to proceed (OpenBLAS uses VFP |
| instructions, and assume an EABIhf ABI). |
| |
| [Peter: update for v0.2.20] |
