2008-03-15Make a major restructuring of the clang tree: introduce a top-levelChris Lattner
lib dir and move all the libraries into it. This follows the main llvm tree, and allows the libraries to be built in parallel. The top level now enforces that all the libs are built before Driver, but we don't care what order the libs are built in. This speeds up parallel builds, particularly incremental ones. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48402 91177308-0d34-0410-b5e6-96231b3b80d8

2007-12-12TargetInfo no longer includes a reference to SourceManager.Ted Kremenek
Moved all clients of Diagnostics to use FullSourceLoc instead of SourceLocation. Added many utility methods to FullSourceLoc to provide shorthand for: FullLoc.getManager().someMethod(FullLoc.getLocation()); instead we have: FullLoc.someMethod(); Modified TextDiagnostics (and related classes) to use this short-hand. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44957 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-29Support floating point literals of the form "1e-16f" which specify an ↵Christopher Lamb
exponent but no decimal point. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44431 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-29Removed potential buffer overrun (spotted by Neil Booth) when ↵Ted Kremenek
NumericLiteralParser converts a parsed literal into an APFloat. We are still performing a copy of the string, which hopefully will be removed eventually for performance reasons. This version now is at least safe. Changed rounding in APFloat construction in NumericLiteralParser from rmTowardsZero to rmNearestTiesToEven. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44422 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-26Added optional pass-by-reference argument "isExact" toTed Kremenek
NumericLiteralParser::GetFloatValue(). Upon method return, this flag has the value true if the returned APFloat can exactly represent the number in the parsed text, and false otherwise. Modified the implementation of GetFloatValue() to parse literals using APFloat's convertFromString method (which allows us to set the value of isExact). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44339 91177308-0d34-0410-b5e6-96231b3b80d8

2) Add support for lexing imaginary constants (a GCC extension): t.c:5:10: warning: imaginary constants are an extension A = 1.0iF; ^ 3) Make the 'invalid suffix' diagnostic pointer more accurate: t.c:6:10: error: invalid suffix 'qF' on floating constant A = 1.0qF; ^ instead of: t.c:6:10: error: invalid suffix 'qF' on floating constant A = 1.0qF; ^ git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41411 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-20At one point there were going to be lexer and parser tokens.Chris Lattner
Since that point is now long gone, we should rename LexerToken to Token, as it is the only kind of token we have. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40105 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-17strtod is more portable than strtof apparently. Instead of making this ↵Chris Lattner
conditional, just always use strtod. This is temporary code anyway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@39972 91177308-0d34-0410-b5e6-96231b3b80d8

2007-07-16Make octal constant lexing use AdvanceToTokenCharacter to give moreChris Lattner
accurate diagnostics. For test/Lexer/comments.c we now emit: int x = 000000080; /* expected-error {{invalid digit}} */ ^ constants.c:7:4: error: invalid digit '8' in octal constant 00080; /* expected-error {{invalid digit}} */ ^ The last line is due to an escaped newline. The full line looks like: int y = 0000\ 00080; /* expected-error {{invalid digit}} */ Previously, we emitted: constants.c:4:9: error: invalid digit '8' in octal constant int x = 000000080; /* expected-error {{invalid digit}} */ ^ constants.c:6:9: error: invalid digit '8' in octal constant int y = 0000\ ^ which isn't too bad, but the new way is better for the user, regardless of whether there is an escaped newline or not. All the other lexer-related diagnostics should switch over to using AdvanceToTokenCharacter where appropriate. Help wanted :). This implements test/Lexer/constants.c. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@39906 91177308-0d34-0410-b5e6-96231b3b80d8
