Escape # and $ in dependency files. Fixes PR15642. llvm-svn: 178540

// PR15642
Simplify depfile quoting test. With -MG we don't actually need to create the files with funky names. Also use a more sensible check-prefix for the NMAKE case. llvm-svn: 235908

Support generating NMake/Jom-style depfiles. NMake is a Make-like builder that comes with Microsoft Visual Studio. Jom (https://wiki.qt.io/Jom) is an NMake-compatible build tool. Dependency files for NMake/Jom need to use double-quotes to wrap filespecs containing special characters, instead of the backslash escapes that GNU Make wants. Adds the -MV option, which specifies to use double-quotes as needed instead of backslash escapes when writing the dependency file.

#include "normal.h"
Fix dependency file escaping. When writing a dependency (.d) file, if space or # is immediately preceded by one or more backslashes, escape the backslashes as well as the space or # character. Otherwise leave backslash alone. This straddles the fence between BSD Make (which does no escaping at all, and does not support space or # in filespecs) and GNU Make (which does support escaping, but will fall back to the filespec as-written if the escaping doesn't match an existing file).

Break \# in a depfile the same way as gcc. Backslash followed by # in a filename should have both characters escaped, if you do it the way GNU Make wants. GCC doesn't, so we do it the way GCC does rather than the way GNU Make wants. llvm-svn: 237304

// Backslash followed by # or space should escape both characters, because
// that's what GNU Make wants. GCC does the right thing with space, but not
// #, so Clang does too. (There should be 3 backslashes before the #.)
// CHECK: a\b\\#c\\\ d.h
