Chris Lattner 51a53f92a5 fix PR3880, fixing a comma swallowing bug handling macros that only take
... arguments.

Chris Lattner beb9055000 remove some dead code. ArgTokens can never be empty, because it is always
terminated with an EOF token.  The condition it is trying to check for is
handled by this code above.

    // Empty arguments are standard in C99 and supported as an extension in
    // other modes.
    if (ArgTokens.empty() && !Features.C99)
      Diag(Tok, diag::ext_empty_fnmacro_arg);

Chris Lattner 73a7cab9e1 change the __VERSION__ string to be more sensible. It would be useful to include the clang version # too.

Chris Lattner 5030e5eabe The individual pieces of an invalid paste as still candidates for expansion.
This matters in assembler mode, where this is silently allowed.
This fixes rdar://6709206.

Ted Kremenek dc637a0be9 PTHManager::Create():
- Make the Diagnostic::Level for PTH errors to be specified by the caller

clang (driver):
- Set the PTHManager diagnostic level to "Diagnostic::Error" for -include-pth
  (a hard error) and Diagnostic::Warning for -token-cache (we can still
  proceed).

Chris Lattner 1d1d80e5f9 rename the <predefines> buffer to <built-in> to solve PR3849.
Add a #include directive around the command line buffer so that
diagnostics generated from -include directives get diagnostics
like:

In file included from <built-in>:98:
In file included from <command line>:3:
./t.h:2:1: warning: type specifier missing, defaults to 'int'
b;

Ted Kremenek 80e239abc0 PTHManager::Create() now creates a PTHManager even if the PTH file contains no
cached tokens. This is for use with -include-pth.

original source file (if any) that was used to generate the PTH cache.

Chris Lattner d14705b9b4 silence some errors that should not apply to .S files on code like:
''

2009-03-18 21:10:12 +00:00
Chris Lattner 2d17ab783b when preprocessing a .S file, unknown directives should just be passed through,
and the token after the # should be expanded if it is not a valid directive.
This allows us to transform things like:

#define FOO BAR
# FOO

into # BAR, even though FOO is not normally expanded for directives.

This should fix PR3833

Douglas Gregor 23d75bb326 Build system changes to use TableGen to generate the various
diagnostics. This builds on the patch that Sebastian committed and
then revert. Major differences are:

  - We don't remove or use the current ".def" files. Instead, for now,
    we just make sure that we're building the ".inc" files.
  - Fixed CMake makefiles to run TableGen and build the ".inc" files
    when needed. Tested with both the Xcode and Makefile generators
    provided by CMake, so it should be solid.
  - Fixed normal makefiles to handle out-of-source builds that involve
    the ".inc" files.

I'll send a separate patch to the list with Sebastian's changes that
eliminate the use of the .def files.

Chris Lattner 7253991f9d add \n characters to the scratch buffer *before* returned tokens.
This prevents caret diagnostics from the scratch buffer from 
including other tokens in the scratch buffer that occurred beforei
them.

Chris Lattner ddb7191920 Next step toward making string diagnostics correct: handle
escapes in the string for subtoken positioning.  This gives
us working examples like:

t.m:5:16: warning: field width should have type 'int', but argument has type 'unsigned int'
  printf("\n\n%*d", (unsigned) 1, 1);
               ^    ~~~~~~~~~~~~

where before the caret pointed two spaces to the left.

Chris Lattner ec396b5114 Fix some issues handling sub-token locations that come from macro expansions.
We now emit:

t.m:6:15: warning: field width should have type 'int', but argument has type 'unsigned int'
  printf(STR, (unsigned) 1, 1);
         ^    ~~~~~~~~~~~~
t.m:3:18: note: instantiated from:
#define STR "abc%*ddef"
                 ^

which has the correct location in the string literal in the note line.

Chris Lattner 5a2e9cb42d fix PR3579: __LINE__ expands to the presumed location of the
*end* of a macro instantiation, not the start of it.  This is
really all about bug-for-bug compatibility with GCC, but not
doing this breaks the FreeBSD kernel.

llvm-svn: 64604
2009-02-15 21:06:39 +00:00
Chris Lattner 9dc9c206d3 track "just a little more" location information for macro instantiations.
Now instead of just tracking the expansion history, also track the full
range of the macro that got replaced.  For object-like macros, this doesn't
change anything.  For _Pragma and function-like macros, this means we track
the locations of the ')'.

This is required for PR3579 because apparently GCC uses the line of the ')'
of a function-like macro as the location to expand __LINE__ to.
