Mikhail Glushenkov 22ce861ffe Reapply 50867: A small refactoring (extract method) + some comment fixes. 
Fixed the build breakage, sorry for that.

Nate Begeman f322eabbce Extend vector member references to include {.hi, .lo, .e, .o} which return a 
vector of the same element type and half the width, with the high, low, even,
and odd elements respectively.

Allow member references to member references, so that .hi.hi gives you the high
quarter of a vector.  This is fairly convenient syntax for some insert/extract
operations.

Remove some unnecessary methods/types in the ExtVectorElementExpr class.

Chris Lattner 2fdcddd78d Don't call into objc front-end when not parsing objc code. This avoids 
crashes because objc types aren't set up right.

Ted Kremenek 0ae11a6f2e Added initial support for supporting __NSString__ in attribute "format". 
Still need to iron out some of the semantics (fixmes are present).

Chris Lattner 49a594e6ab More than just loads can read from memory: readonly calls like strlen 
also need to be checked for memory modifying instructions before we
can sink them.  THis fixes the second half of PR2297.

llvm-svn: 50860
 2008-05-08 17:37:37 +00:00
Chris Lattner 4fa09669d8 Make instcombine's DSE respect loads as well as stores. It is not safe to 
delete the first store in:

store x -> p
load p
store y -> p

This is for PR2297.

llvm-svn: 50859

Instruction::mayWriteToMemory stronger for invokes.

Duncan Sands 9897eee483 Get exception handling working again on 64 bit 
Darwin.  This is a hack of course, but it does
at least look at the right thing: gotpcrel means
that this is already an offset, so an explicit
offset is not needed (and wrong).  I think this
is good enough for the moment: Anton is working
on something better.

Sanjiv Gupta 15cb669039 Added -g command line options to clang for generating source level debug information. This patch currently enables generation of line number debug information (stoppoints) and region begin/end debug information. The new files CGDebugInfo.h and CGDebugInfo.cpp implements the debug info manager class CGDebugInfo.

Chris Lattner b781dc79aa Add basic support for the pic-* target triples and add support for 
targets that do not support recursion (and thus codegen stack variables
as globals).

Chris Lattner d330036c06 The awesome GNU "comma elision extension" works with both the standard 
__VA_ARGS__ syntax as well as with the amazingly awesome GNU "named
