I use gcc 3.4 with "--with-debug" options. And now I'm sure3.4 mis-compiled "lisparit.o". And I compared the assembly code compiled by 3.4 and 3.3. But the difference is so big (the output of "diff" is about 228423 lines). Do you have any suggestion on find out the problematic part from the difference . 4. figure out which function is miscompiled (e.g., by using binary search) What you mean by "using binary search" Thanks -Charles He |
