Hi,
This fixes up documentation for the -marm option and changes the
behaviour of mthumb to reject the negative options to bring this to
behave similar to the marm option. The option needs to be documented
since we now have situations where toolchains default to Thumb state and
folks need a way of overriding this. I would like a review of this
before committing it since this is a change to the command line options.
Tested by building a cross toolchain to arm-linux-gnueabi and verified
that -mno-thumb is rejected and looking up the documentation after it
was rebuilt.
Ok ?
cheers
Ramana
