changes in my tree, so I don't have a testcase which affects trunk.

as far as I can tell, and it fixes code like test/CodeGen/functions.c.

(Whatever performance effect it might have, crashing on a 
construct like this isn't really acceptable; I've run into this 
multiple times.)

implement bitfield codegen (although I don't envy the person who 
implements it).  This also prevents a crash on code like that from PR2309
(it's still broken, but it fails more gracefully).

they were causing bad code to be emitted.  There are two fixes here: one 
makes sure we emit a string that is long enough, and one makes sure we 
properly handle string initialization in init lists.

used for _Bool is not the same as the primitive width (which for _Bool 
is 1 bit).  The load and store changes add some casts to make the 
types consistent.  The EmitLValue changes make sure that the pointer is 
of an appropriate type for loading the bitfield.

This isn't perfect, but it's an improvement, and getting everything 
right depends on actually laying out structs in an ABI-compliant way.

expressing the full flexibility of the LLVM shufflevector instruction.  
The expected immediate usage is in *mmintrin.h, so that they don't 
depend on the mess of gcc-inherited (and not completely implemented)
shuffle builtins.

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.

llvm-svn: 50892

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.

targets that do not support recursion (and thus codegen stack variables
as globals).

type should be internal, not weak/linkonce.

reimplemented in Sema someday.  This is tracked in PR2236.  Until then
disabling it removes some bogus diagnostics (see 2236).
