Bill Wendling bb455154a1 Remove the 'unaligned load' builtins now that they're no longer used in the *mmintrin.h files.
llvm-svn: 131300
2011-05-13 18:52:28 +00:00
Bill Wendling e106c34817 LLVM doesn't always optimize away the four loads from this:
(__m128){ p[0], p[1], p[2], p[3] }

which produces really bad code. This could be done in instcombine, but it's
probably better to do it in the front-end instead.

Chris Lattner 30107ed600 fold memcpy/set/move_chk to llvm.memcpy/set/move when the sizes
are trivial.  This exposes opportunities earlier, and allows fastisel
to do good things with these at -O0.

This addresses rdar://9289468 - clang doesn't fold memset_chk at -O0

John McCall 20f6ab828a Fix a latent bug where, after emitting an expression statement, we would
delete the block we began emitting into if it had no predecessors.  We never
want to do this, because there are several valid cases during statement
emission where an existing block has no known predecessors but will acquire
some later.  The case in my test case doesn't inherently fall into this 
category, because we could safely emit the case-range code before the statement
body, but there are examples with labels that can't be fallen into 
that would also demonstrate this bug.

Chandler Carruth bc8cab16c5 Improve the representation of the atomic builtins in a few ways. First, we make
their call expressions synthetically have the "deduced" types based on their
first argument. We only insert conversions in the AST for arguments whose
values require conversion to match the value type expected. This keeps PR7600
closed by maintaining the return type, but avoids assertions due to unexpected
implicit casts making the type unsigned (test case added from Daniel).

The magic is moved into the codegen for the atomic builtin which inserts the
casts as needed at the IR level to raise the type to an integer suitable for
the LLVM intrinsic. This shouldn't cause any real change in functionality, but
now we can make the builtin be more truly polymorphic.

John McCall b6cc2c0439 Inspired by seeing "MIPS" go by in the commits, I've gone ahead and
implemented a (codegen) target hook for __builtin_extend_pointer.
I'm also making it return a uint64_t instead of an unsigned word;  this
comports with typical usage (i.e. the one use I know of).

I don't know if any of the existing targets requires this hook to be
set (other than x86 and x86_64, which I know do not).

Daniel Dunbar a7566f163a IRgen: Add CreateMemTemp, for creating an temporary memory object for a particular type, and flood fill. - CreateMemTemp sets the alignment on the alloca correctly, which fixes a great many places in IRgen where we were doing the wrong thing.
- This fixes many many more places than the test case, but my feeling is we need to audit alignment systematically so I'm not inclined to try hard to test the individual fixes in this patch. If this bothers you, patches welcome!

The decl wasn't being passed down, which meant that function attributes were not

wrong calling convention, and instcombine would come along and merrily shred all
the calls to it. :)
