I have tried in both GDB and Insight, the md file doesn't appear. The
list you mentioned is at left-top of the Insight GUI?
There is no such file in that list.
I don't know what 's the "a target triple " mean. Sorry.

You solution seems to make sense, but I 've already tried your
solution to remove the -gdwarf-2 and -g3  flag.
And the md file still does not appear in Insight.

There is no assembler. it compile the c language to my machine assemble.
MD file is compounded with RTL (GCC intermediate language), which used
to describe machine instruction pattern, and C language.

HiThanks.
