Chris Lattner 8ec6e8af60 add a handy helper method to instruction, useful for determining 
whether it is used outside of some block.  This can be used to see
if there are any non-local references, for example.

Chris Lattner b3b6007c8b Add a new Jump Threading pass, which will handle cases 
such as those in PR2235.  Right now the pass is not very
effective. :)

 2008-04-20 19:59:12 +00:00
Chris Lattner 14cd1ee95f Two improvements to initializer parsing: 
1. If we hit a semantic error, try harder to recover to emit
   diagnostics for later initializer errors (PR2241).
2. Don't leak parsed initializers on an error.

 2008-04-20 19:07:56 +00:00
Chris Lattner 4885b97664 for exponent-related errors, emit the diagnostic on the 'e' or 'p'.

 2008-04-20 18:47:55 +00:00
Chris Lattner 48a9b9beeb when emitting diagnostics about some character in a numeric 
literal, indicate what character the error is about or where
it would be.  For example:

pr2241.c:1:17: error: exponent has no digits
float f[] = { 1e  , 1ee0 };
                ^

Nicolas Geoffray 568f9818f7 Do not hold the JIT lock when materializing a function and verify if the 
function has already been codegen'd. This is required by the Java class loading
mechanism which executes Java code when materializing a function.

Chris Lattner 2cc4e23252 Restructure and simplify Sema::ObjCQualifiedIdTypesAreCompatible, 
deleting dead code, making other code more obvious, and fixing a
bug.  This fixes these (bogus) warnings in release mode:

SemaExprObjC.cpp:383: warning: 'RHSProtoE' may be used uninitialized in this function
SemaExprObjC.cpp:383: warning: 'RHSProtoI' may be used uninitialized in this function

Dale Johannesen 64bbdb17f5 Check that APFloat::convert is not trying to target 
ppc long double, which doesn't work.

This may break some stuff temporarily, but I want to
avoid the propagation of code that assumes this works.
