* Add field PaddingType to ABIArgInfo which specifies the type of padding thatAkira Hatanaka2012-01-071-6/+15
| | | | | | | | | | is inserted before the real argument. Padding is needed to ensure the backend reads from or writes to the correct argument slots when the original alignment of a byval structure is unavailable due to flattening. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147699 91177308-0d34-0410-b5e6-96231b3b80d8

* fix PR5179 and correctly fix PR5831 to not miscompile.Chris Lattner2010-07-301-23/+32
| | | | | | | | | | | | | | | | | | | | | The X86-64 ABI code didn't handle the case when a struct would get classified and turn up as "NoClass INTEGER" for example. This is perfectly possible when the first slot is all padding (e.g. due to empty base classes). In this situation, the first 8-byte doesn't take a register at all, only the second 8-byte does. This fixes this by enhancing the x86-64 abi stuff to allow and handle this case, reverts the broken fix for PR5831, and enhances the target independent stuff to be able to handle an argument value in registers being accessed at an offset from the memory value. This is the last x86-64 calling convention related miscompile that I'm aware of. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109848 91177308-0d34-0410-b5e6-96231b3b80d8

* Kill off the 'coerce' ABI passing form. Now 'direct' and 'extend' alwaysChris Lattner2010-07-291-16/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | have a "coerce to" type which often matches the default lowering of Clang type to LLVM IR type, but the coerce case can be handled by making them not be the same. This simplifies things and fixes issues where X86-64 abi lowering would return coerce after making preferred types exactly match up. This caused us to compile: typedef float v4f32 __attribute__((__vector_size__(16))); v4f32 foo(v4f32 X) { return X+X; } into this code at -O0: define <4 x float> @foo(<4 x float> %X.coerce) nounwind { entry: %retval = alloca <4 x float>, align 16 ; <<4 x float>*> [#uses=2] %coerce = alloca <4 x float>, align 16 ; <<4 x float>*> [#uses=2] %X.addr = alloca <4 x float>, align 16 ; <<4 x float>*> [#uses=3] store <4 x float> %X.coerce, <4 x float>* %coerce %X = load <4 x float>* %coerce ; <<4 x float>> [#uses=1] store <4 x float> %X, <4 x float>* %X.addr %tmp = load <4 x float>* %X.addr ; <<4 x float>> [#uses=1] %tmp1 = load <4 x float>* %X.addr ; <<4 x float>> [#uses=1] %add = fadd <4 x float> %tmp, %tmp1 ; <<4 x float>> [#uses=1] store <4 x float> %add, <4 x float>* %retval %0 = load <4 x float>* %retval ; <<4 x float>> [#uses=1] ret <4 x float> %0 } Now we get: define <4 x float> @foo(<4 x float> %X) nounwind { entry: %X.addr = alloca <4 x float>, align 16 ; <<4 x float>*> [#uses=3] store <4 x float> %X, <4 x float>* %X.addr %tmp = load <4 x float>* %X.addr ; <<4 x float>> [#uses=1] %tmp1 = load <4 x float>* %X.addr ; <<4 x float>> [#uses=1] %add = fadd <4 x float> %tmp, %tmp1 ; <<4 x float>> [#uses=1] ret <4 x float> %add } This implements rdar://8248065 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109733 91177308-0d34-0410-b5e6-96231b3b80d8
