* Lex: Use the correct types for MS integer suffixesDavid Majnemer2014-06-21
| | | | | | | | | | | | | | | | Something went wrong with r211426, it is an older version of this code and should not have been committed. It was reverted with r211434. Original commit message: We didn't properly implement support for the sized integer suffixes. Suffixes like i16 were essentially ignored instead of mapping them to the appropriately sized integer type. This fixes PR20008.

* Remove limits on the number of fix-it hints and ranges in the DiagnosticsEngine.Alexander Kornienko2014-05-22
| | | | | | | | | | | | | | | | | | | Summary: The limits on the number of fix-it hints and ranges attached to a diagnostic are arbitrary and don't apply universally to all users of the DiagnosticsEngine. The way the limits are enforced may lead to diagnostics generating invalid sets of fixes. I suggest removing the limits, which will also simplify the implementation.

* Rename CanFitInto64Bits to alwaysFitsInto64Bits per discussion on IRC.Jordan Rose2012-09-25
| | | | | | | | | | | | | This makes the behavior clearer concerning literals with the maximum number of digits. For a 32-bit example, 4,000,000,000 is a valid uint32_t, but 5,000,000,000 is not, so we'd have to count 10-digit decimal numbers as "unsafe" (meaning we have to check for overflow when parsing them, just as we would for numbers with 11 digits or higher). This is the same, only with 64 bits to play with. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164639 91177308-0d34-0410-b5e6-96231b3b80d8
