Hmm... for myself, during this week end, I shall: 1. construct the related environments. make x86, h8300 cross-compiler (disable-release, enable-debug). let them compile the same file which can cause issue under h8300. 2. learn about these .i files. know about .i files. compare the related .i files between x86, arm, h8300. know the direct cause. 3. can debug gcc (may with .i file) with gdb. Welcome any additional information or suggestions. :-) > jeff > > > Thanks -- Chen Gang
