X86: Fix kernel Input/Output GetElementPtr offset issue
7d6cde16bde7c6c65d47b51bb992bdfb94077393 21-Oct-2015 Yong Chen <yong.a.chen@intel.com> X86: Fix kernel Input/Output GetElementPtr offset issue


The disagreement between module and x86 target datalayout causes
mismatched size calculation of structs with 64-bit scalar fields.

This patch solves the issue by treating input and output pointers as
byte* pointers, indexing them with explicit byte offsets computed using
a modified data layout for x86, with alignment for 64-bit scalars set to
8-bytes, and casting the indexed pointers back to the real type.

57fd9f882f3359be4201c42b02aebf785d311df2 08-Apr-2016 David Gross <dgross@google.com> If a general reduction kernel lacks a combiner function, synthesize one.

The CPU reference driver can only go multithreaded for a reduction kernel
if that kernel has a combiner function.

ba1a8f1e6f3eb5b7069e9ba1575f16e393c84c23 25-Nov-2015 Dean De Leo <dean@codeplay.com> Make RSKernelExpand use memory rather than registers.

The RSKernelExpand pass generates a loop around the main kernel body.
This patch changes it to use LLVM memory with loads and stores rather
than generating the SSA directly. This is required in order to be able
to attach debugging information to the memory location associated with
the loop iteration index variable, enabling the debugger to inspect
current thread coordinate. The regular SSA form of LLVM IR doesn't allow
this to be done efficiently.

If optimizations are enabled, the subsequent passes promote memory back
to registers, avoiding potential performance regressions.

forEach kernel expansion.

InStep and OutStep are not used by expanded new-style forEach kernels.
Instead, the strides are inferred from the type information available
to the kernel expansion pass.

Bug: 22631253

Rename the RSForEachExpand pass / source file to RSKernelExpand. In
addition to already being responsible for expanding foreach-style
kernels, RSKernelExpand now expands reduce-style kernels from

define foo @func(foo %a, foo %b)


define void @func.expand(i8* %inBuf, i8* %outBuf, i32 len)

The expanded function reduces a sub-range of its input.
