It also has (read-rtl.c example): Stage 2: -g -gtoggle Stage 3: -g Being successful for the comparison it does not leave . . ./work/. . . havi= ng copies of the likes of the compared stage2 and stage3 read-rtl.o files : ju= st the one final one at . . ./work/.build/gcc/build/read-rtl.o . Still it suggests that Stage 2 had debug information turned off by -gtoggle while Stage 3 had it turned on --yet the comparison passed. Unfortunately this might mean having to look at the details of the comparis= on technique for powerpc and the data it was processing to find what makes it classify its read-rtl.o's as mismatched. Merely noting the variations in having debug information vs. not is apparen= tly not enough to have a mismatch as the classification. Bad assumption on my p= art, just like the tie to WITH_DEBUG was a bad assumption on my part. Still 32-bit powerpc does fail its comparison so the bugzilla report still applies overall. It just would read better and quicker if I could eliminate= my false assumptions from the description and comments. --=20 You are receiving this mail because: You are the assignee for the bug.=
