Per section 3.18 of GCC manual, GCC should recognize the "-fdump-rtl-sibling"
option. When I try to invoke this option, GCC gives my following error: "
g++ -fdump-rtl-sibling test.cc
cc1plus: error: unrecognized command-line option ‘-fdump-rtl-sibling’
"
I am unsure to which component this sort of bugs should go, so I file this
under "other" category.
