Subject: [PATCH] Makefile: Don't specify mabi or march
|

|
||||
To avoid
|

can't link double-float modules with soft-float modules
|
||||
errors when building 32-bit openSBI don't specify mabi or march.

Subject: [PATCH] Makefile: unconditionally disable SSP
|
||||
|
||||
Though -nostdlib is passed in {C,+AS,DTSCPP}FLAGS, -fno-stack-protector
|
||||
must also be passed to avoid linking errors related to undefined
|
||||
references to '__stack_chk_guard' and '__stack_chk_fail' if toolchain
|
||||
enforces -fstack-protector.
