[PATCH] D145726: Fix assembler error when -g and -gdwarf-* is passed with -fno-integrated-as.

[Eli Friedman via Phabricator via cfe-commits]

efriedma added a comment.

Following reproduces for me (clang from main, Ubuntu 16.04).

  $ cat test.cpp
  int foo()
  {
          int i=6;
          do --i; while (!(i%3));
          do {} while (!(i%5));
          return 0;
  }
  $ clang++ test.cpp -c -fno-integrated-as -gdwarf-4 -O2 -fno-finite-loops
  /tmp/test-f97496.s: Assembler messages:
  /tmp/test-f97496.s:18: Error: file number 1 already allocated
  clang++: error: assembler command failed with exit code 1 (use -v to see invocation)

I think it triggers when the assembly file contains code before the first ".file" directive.
