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).
|
||
