I follow the instructions from this
website:http://gcc.gnu.org/wiki/DebuggingGCC.
but things is not going to be correct.
bacause when cc1 build libgcc2.c, some error occurred. I have debug
cc1. But If I have to build libgcc2.c, some complex parameter have to
pass.
I don't know what's xgcc is, but it seems mandatory. Maybe xgcc will
trigger the cc1, after xgcc processes some preprocessing.
Anyway, I don't know.
Does anybody have some relevant materials or website, which can give
me an overview.
And this is the debug problem. And hope somebody can give me a clue.
