question about ecj integration

[Jakob Praher]

hi,

I am sorry to not attending this years FOSDEM. I know it was great. :-(
I hope to make it next year.

Since you really consider using ecj as the "jstage2" java frontend, I
have a question:

How do you generate code with ecj?
-> Do you have a CNI interface to gcc's TREE language?
-> Do you directly generate gnu assmembler (which is not a real option,
since you miss all the GIMPLE/SSA and RTL optimization passes)

I think I remember to having heard that you use the jc1 compiler to
compile the ecj source files to native code in the first run.

Are the folks at eclipse restricting ecj to java 1.4 language features?
Or do you provide patches for converting the ecj features to whatever
jc1 is able to compile?

I am just courious. Thanks in advance
