indexing an empty std::vector.

Updates to all clients.

mnemonics from their operands instead of single spaces. This makes the
assembly output a little more consistent with various other compilers
(f.e. GCC), and slightly easier to read. Also, update the regression
tests accordingly.

llvm-svn: 40648

Fix GLIBCXX_DEBUG error owing to dereference of end iterator.  There's
no guarantee that an instruction returned by getDependency exists in
the maps.

Redo and generalize previously removed opt for pinsrw: (vextract (v4i32 bc (v4f32 s2v (f32 load ))), 0) -> (i32 load )

Use simple analysis interface to preserve analysis info maintained by other loop passes.

Right now, this interface provides hooks for only to operations, 1) clone basic block 2) delete value.

function result to be passed in a register. This implements the GCC regparm
function attribute for llvm by translation to the InReg parameter attribute 
and fixes test/CFrontend/2002-07-30-SubregSetAssertion.c

llvm-svn: 40619

front end converts regparm attribute on the gcc function into InReg attribute 
on the llvm function. This fixes test/CFrontend/2002-07-30-SubrefSetAssertion.c
