Don't require that, during template deduction, a template specialization type as a function parameter has at least as many template arguments as one used in a function argument (not even if the argument has been resolved to an exact type); the additional parameters might be provided by default template arguments in the template. We don't need this check, since we now implement [temp.deduct.call]p4 with an additional check after deduction. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169475 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-05Format strings: offer a cast to 'unichar' for %C in Objective-C contexts.Jordan Rose
For most cases where a conversion specifier doesn't match an argument, we usually guess that the conversion specifier is wrong. However, if the argument is an integer type and the specifier is %C, it's likely the user really did mean to print the integer as a character. (This is more common than %c because there is no way to specify a unichar literal -- you have to write an integer literal, such as '0x2603', and then cast it to unichar.) This does not change the behavior of %S, since there are fewer cases where printing a literal Unicode *string* is necessary, but this could easily be changed in the future. <rdar://problem/11982013> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169400 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-05Format strings: add more expression types that don't need parens to cast.Jordan Rose

2012-12-05Format strings: a character literal should be printed with %c, not %d.Jordan Rose
The type of a character literal is 'int' in C, but if the user writes a character /as/ a literal, we should assume they meant it to be a character and not a numeric value, and thus offer %c as a correction rather than %d. There's a special case for multi-character literals (like 'MooV'), which have implementation-defined value and usually cannot be printed with %c. These still use %d as the suggestion. In C++, the type of a character literal is 'char', and so this problem doesn't exist. <rdar://problem/12282316> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169398 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-05Format strings: the correct conversion for 'char' is %c, not %d or %hhd.Jordan Rose
We tried to account for 'uint8_t' by saying that /typedefs/ of 'char' should be corrected as %hhd rather than %c, but the condition was wrong. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169397 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-04Add -whole-archive around the ASan runtime archive in the link command.Chandler Carruth
This ensures that even though it comes first, we pick up its .o files. Note that if we can use this (or something similar / equivalent) on other platforms, we could potentially remove ReplaceOperatorsNewAndDelete from the ASan runtimes. We should probably do something similar for TSan and MSan as well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169328 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-04Use the 'count' attribute to calculate the upper bound of an array.Bill Wendling
The count attribute is more accurate with regards to the size of an array. It also obviates the upper bound attribute in the subrange. We can also better handle an unbound array by setting the count to -1 instead of the lower bound to 1 and upper bound to 0. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169311 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-04Currently, with -fsanitize=address, the driver appends libclang_rt.asan.a toMatt Beaumont-Gay
the link command. This all works fine when the driver is also responsible for adding -lstdc++ to the link command. But, if -lstdc++ (or libstdc++.a, etc) is passed explicitly to the driver, the ASan runtime will appear in the link command after the standard library, leading to multiple-definition errors for the global 'operator new' and 'operator delete'. Fix this in a painfully simple way, by inserting libclang_rt.asan.a at the start of the link command instead of the end. If we need to do something more clever, we can walk the link command looking for something that resembles libstdc++ and insert libclang_rt.asan.a as late as possible, but the simple solution works for now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169310 91177308-0d34-0410-b5e6-96231b3b80d8

The count field is necessary because there isn't a difference between the 'lo' and 'hi' attributes for a one-element array and a zero-element array. When the count is '0', we know that this is a zero-element array. When it's >=1, then it's a normal constant sized array.
