Re: [PATCH v2] C-SKY: Support -mfloat-abi=hard.

Hi Jojo,

Nowhere is this rule directly stated. But there are indent options 
showed in 
https://www.gnu.org/prep/standards/html_node/Formatting.html#Formatting 
corresponding to recommendations of C formatting style, which use the 
defualt 8 clumns tab wide.

Hi,

        Is there coding rule with it ?

        I can not find it from 
https://www.gnu.org/prep/standards/html_node/index.html
        and https://gcc.gnu.org/codingconventions.html

        Could you give me any hints ?

        Thanks.

These is one more thing you shoud pay attention to, if the spaces number
reaches 8 at begining of a line, you should use tab instead of 8 spaces.


Thanks,
