Linux/PROCESSOR-SDK-AM437X: What options are used with arm-linux-gnueabihf-gcc?

Part Number: PROCESSOR-SDK-AM437X

Tool/software: Linux

I installed ti-processor-sdk-Linux-am437x-evm-05.02.00.10-linux-x86-Install.bin.

Under the install directory (/Linux-devkit/sysroots/...), there is a gcc compiler with a default Makefile and Rules.make.

In Rules.make, CFLAGS= -march=armv7-a -marm -mfpu=neon -mfloat-abi=hard

My Linux application compiles and executes with the default options.

Is that correct for the AM437x with ARM9? I don't think arm9 is a valid option.
