Subject: [PATCH 18/62] Make.default: use correct flags to disable unaligned
|
|||
|
|
access for 32 bit ARM

The GCC flag to disable unaligned access on 32bit ARM is
|
|||
|
|
-mno-unaligned-access, not -mstrict-align (which is used on aarch64):

|
|||
|
|
|
|||
|
|
Otherwise build dies with:
|
|||
|
|
arm-linux-gnueabihf-gcc: error: unrecognized command line option
|
|||
|
|
‘-mstrict-align’; did you mean ‘-Wstrict-aliasing’?
