I was testing out LTO and found -fdump-tree-all did not work. I even made sure that -fdump-tree-all was added to the command line: /home/pinskia/lto-gcc/libexec/gcc/x86_64-unknown-linux-gnu/4.5.0/lto1 -quiet -dumpbase lua.o -mtune=generic -auxbase-strip /tmp/ccMdUKXU.lto.o -O2 -Wall -version -fdump-tree-all @t.sh
And it still does not work. -- Summary: -fdump-tree-all does not work with lto Product: gcc Version: 4.5.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: lto AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: pinskia at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41564
