Hi,
As I known,the .md file will be needed:the parse
tree is used to generate an RTL insn list based
on named instruction patterns,then the insn list
is matched against the RTL templates to produce
assembler code.So .md file is needed.
But I dont know the sequence of function calling,
Since I did not debug cc1,and I am a newbie on
GCC developing.
Regards,
Alan
