[PATCH] D64706: [tools] [llvm-objdump] Default to reading from stdin not a.out

[Saleem Abdulrasool via Phabricator via llvm-commits]

compnerd added a comment.

`objcopy` is often used in autotools to run tests of what the compiler is doing.  I'm afraid that changing that behaviour will break the autoconf tests which rely on the behaviour (`a.out` is what the compiler generates by default, and that is why the tool defaults to that filename).  So, if you have something like the following:

  cc test.c
  objcopy --extract-dwo

to test whether you can do split-debug with dwarf packages, it will break.
