Hm, worked for me last time. Re-checking with r166798. Tonto works for me. Created attachment 22429 [details]
The src.alt for 465.tonto
Can you try this alternate source for tonto with
-O3 -funroll-loops -ffast-math -fwhole-program -flto=jobserver -fuse-linker-plugin
I have different alternate source, calling destroy_ptr_part_ instead. But I can't parse the perl patch, so I'm not 100% sure. As of revision 166870, tonto failed with test input, "-i test", and passed with normal input. Tonto also failed without LTO on test input:
Running 465.tonto test base lnx32e-gcc default

Miscompare of stdout
*** Bug 46842 has been marked as a duplicate of this bug. *** This is not a optimization bug because it fails with -O0. I am seeking a working src_alt. Thanks. Tonto always fails with test input. Ignore it. It is a real bug. Dup. *** This bug has been marked as a duplicate of bug 46842 *** |
