Michael J. Spencer 4992ca4b17 Reorganize predefined macros for all Windows targets. 
This adds an option to set the _MSC_VER macro without
recompiling. This is very useful when testing compatibility
with the Windows SDK and c++stdlib headers.

-fmsc-version=<version> (defaults to VS2003 (1300))

Chris Lattner a09e8efd1f Per discussion with Sanjiv, remove the PIC16 target from mainline. When/if 
it comes back, it will be largely a rewrite, so keeping the old codebase
in tree isn't helping anyone.

Daniel Dunbar 092b6fb187 Driver: Add a -stdlib= argument which can be used to select the C++ standard 
library to use.
 - This is currently useful for testing libc++; you can now use 'clang++
   -stdlib=libc++ t.cpp' to compile using it if installed.

 - In the future could also be used to select other standard library choices if
   alternatives become available (for example, to use an alternate C library).

Jeffrey Yasskin caa710dfd2 PR7245: Make binding a reference to a temporary without a usable copy 
constructor into an extension warning into the error that C++98 requires.

llvm-svn: 105529
 2010-06-07 15:58:05 +00:00
Jeffrey Yasskin 2f96e9f5c9 Add an extension to avoid an error when a global template has the same name as 
a member template, and you try to call the member template with an explicit
template argument.  See PR7247 

For example, this downgrades the error to a warning in:

template<typename T> struct set{};
struct Value {
    template<typename T>
    void set(T value) {
    }
};
void foo() {
    Value v;
    v.set<double>(3.2);  // Warning here.
}

Douglas Gregor ffed1cb339 Introduce a limit on the depth of the template instantiation backtrace 
we will print with each error that occurs during template
instantiation. When the backtrace is longer than that, we will print
N/2 of the innermost backtrace entries and N/2 of the outermost
backtrace entries, then skip the middle entries with a note such as:

  note: suppressed 2 template instantiation contexts; use
  -ftemplate-backtrace-limit=N to change the number of template
  instantiation entries shown

This should eliminate some excessively long backtraces that aren't
providing any value.

Chris Lattner b35583df52 add a new driver-level -ferror-limit=412 option, which causes clang to stop 
emitting diagnostics after it has produced that many errors.  Give this a
default value of 20 which produces plenty of errors for people to fix before
recompiling but not so many that their entire console scrolls away when the
compiler gets confused.  The experience looks like this:

$ clang foo.c
<tons of crap>
foo.c:102:3: error: unknown type name 'somethingbad'
  somethingbad x;
  ^
fatal error: too many errors emitted, stopping now
36 warnings and 20 errors generated.
