Hi, For those who are interested in looking at all changes for the fixed-point branch, I created a diff file of 147 files. This diff file doesn't have changes requested by Mark.
Because the diff file is large, I compressed it and posted it to the GCC wiki page (20070608gcc.diff.gz). http://gcc.gnu.org/wiki/FixedPointArithmetic?action=AttachFile To make the merging process manageable, we will have a plan to merge changes steps by steps to ensure that everything still works after every step. Thanks a lot! Regards, Chao-ying 1.
