| | | | | | | | Switch some warnings over to errors which should never have been warnings in the first place. (Also, a minor fix to the preprocessor rules for integer literals while I'm here.) llvm-svn: 186903

| | | | | | | Nearly all of these changes are one-to-one replacements; the few that aren't have to do with custom identifier validation. llvm-svn: 174768

* PR15067: Don't assert when a UCN appears in a C90 file.Jordan Rose2013-01-271-1/+1
| | | | | | | Unfortunately, we can't accept the UCN as an extension because we're required to treat it as two tokens for preprocessing purposes. llvm-svn: 173622

I also manually added quite a few missing headers that were uncovered by shuffling the order or moving headers up to be main-module-headers. llvm-svn: 169237
* LiteralSupport: Don't overflow the temporary buffer when decoding invalid ↵Benjamin Kramer2012-11-081-5/+6

* Rename CanFitInto64Bits to alwaysFitsInto64Bits per discussion on IRC.Jordan Rose2012-09-251-2/+2
| | | | | | | | | | | | | 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. llvm-svn: 164639
* Optimize NumericLiteralParser::GetIntegerValue().Dmitri Gribenko2012-09-251-9/+21
| | | | | | | It does a conservative estimate on the size of numbers that can fit into uint64_t. This bound is improved. llvm-svn: 164624
* Small cleanup of literal semantic analysis: hiding 'char *' pointers behindDmitri Gribenko2012-09-241-11/+11
| | | | | | | StringRef makes code cleaner. Also, make the temporary buffer smaller: 512 characters is unreasonably large for integer literals. llvm-svn: 164484

* Unify naming of LangOptions variable/get function across the Clang stack ↵David Blaikie2012-03-111-6/+6
| | | | | | | | | | (Lex to AST). The member variable is always "LangOpts" and the member function is always "getLangOpts". Reviewed by Chris Lattner llvm-svn: 152536

| | | | | | | | | | | | | | | | | | | | Updates ProcessUCNExcape() for C++. C++11 allows UCNs in character and string literals that represent control characters and basic source characters. Also C++03 allows UCNs that refer to surrogate codepoints. UTF-8 sequences in character literals are now handled as single c-chars. Added error for multiple characters in Unicode character literals. Added errors for when a the execution charset encoding of a c-char cannot be represented as a single code unit in the associated character type. Note that for the purposes of this error the asso- ciated character type for a narrow character literal is char, not int, even though in C narrow character literals have type int. llvm-svn: 148389
