            Bug ID: 113525
           Summary: GCC does not recognize "-fdump-rtl-sibling" command
                    line option
           Product: gcc
           Version: 13.2.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: other
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

My GCC config: 
Using built-in specs.

gcc version 13.2.1 20230801 (GCC) 

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.

The pass named sibling was removed a long time ago but the documentation was
not updated ...

It was removed in r0-115834-gbe147e848b387d for GCC 4.8.0 .


unshare was also removed at the same time too.

Confirmed. Just a documentation not being in sync with the source.


Note seqabstr was also removed at r0-92254-g824523999285e7 (for 4.5.0).
