Question about gimple frontend

[Lyu Mitnick]

Hello all,

I notice that there is a project Gimple FE - A Gimple Front End
(http://gcc.gnu.org/wiki/GimpleFrontEnd).
I have read the GCC document to find how to use. And I found the
option, -fdump-tree-gimple, which can
be used to output gimple. However I cannot find any option to read
gimple in, and continues compiling.
Would you mind to tell me how to do it?

Thanks a lot

It's a project.  It's not complete and it's not part of mainline GCC.
As the wiki page says, the work is being done on the gimple-front-end
branch.

Hello Ian,

Thanks for your reply. I have check out the source code from gimple-front-end
branch, and build gimple1 successfully. However neither took the example of
GimpleFrontEnd wiki nor *.gimple in gcc/testsuite/gimple.dg as input, gimple1
just check/parse but output nothing in *.s. My running script is as follows:

$ gimple1 20120523-1.gimple

I am wondering whether I misuse gimple1 or the project status is systax checking
only.

Thanks a lot

I have not used that project.  You will have to ask one of the
developers working on it.
