Comment (by Ben Gamari <ben@…>):

 In [changeset:"d75bba852db208b1d9fcb84dab01598a765d2534/ghc" d75bba8/ghc]:
 {{{
 #!CommitTicketReference repository="ghc"
 revision="d75bba852db208b1d9fcb84dab01598a765d2534"
 Add rtsopts ignore and ignoreAll.

 These ignore commandline arguments for ignore and commandline as well as
 GHCRTS arguments for ignoreAll. Passing RTS flags given on the command
 line along to the program by simply skipping processing of these flags
 by the RTS.

 This fixes #12870.

 Test Plan: ./validate
