Owen Anderson 36b48de43c Duncan convinced me that it's not possible to transform control-based escapes into 
data-based ones.  Just be conservative when analyzing control-based escapes.

ivar.

Chris Lattner 7c2e9809b1 Simplify raw mode lexing by treating an unterminate /**/ comment the 
same we we do an unterminated string or character literal.  This makes
it so we can guarantee that the lexer never calls into the 
preprocessor (which would be suicide for a raw lexer).

Chris Lattner 6b0c5ad096 add a comment.

 2008-10-12 01:23:27 +00:00
Chris Lattner 50c9050037 Change how raw lexers are handled: instead of creating them and then 
using LexRawToken, create one and use LexFromRawLexer.  This avoids
twiddling the RawLexer flag around and simplifies some code (even 
speeding raw lexing up a tiny bit).

This change also improves the token paster to use a Lexer on the stack
instead of new/deleting it.

Chris Lattner da435910e8 Fix PR2697 by rewriting the '(X / pos) op neg' logic. This also changes 
a couple other cases for clarity, but shouldn't affect correctness.

Chris Lattner 2753955fc0 Change CALLSEQ_BEGIN and CALLSEQ_END to take TargetConstant's as 
parameters instead of raw Constants.  This prevents the constants from
being selected by the isel pass, fixing PR2735.

Dale Johannesen 05b54c2af4 Fix SSE4.1 roundss, roundsd. While the instructions have 
the same pattern as roundpd/roundps, the Intel compiler 
builtins do not:  rounds* has an extra operand.  Fixes
