2129b1e27d knc.h: Fixed __rsqrt_varying_float() to use _mm512_invsqrt_ps() instead of _mm512_invsqrt_pd() 
This was a typo.

Fix a bug where an unsigned index variable in subscript is sxt to 64 bit
 2012-11-05 21:51:38 -08:00
Peng Tu
04d32ae3e6 Inside LLVM, both signed and unsigned integer are represented with the same type - i32 - effectively a signed int32. On 64 bit target, we must generate explicit sxt/zxt during the LLVM IR creation to promote the array index into 64 bit. Otherwise, an unsigned int index becomes signed int index in the LLVM IR. 
I limit the fix to uniformed index to avoid widening a varying index vector to 64 bits.  This means that the 32 bit values in the varying indices must be positive and smaller than 2^31 at the runtime for a program to behave correctly.

6412876f64 Remove unused __reduce_add_uint{32,64} target functions. 
The stdilb code just calls the signed int{32,64} functions,
which gives the right result for the unsigned case anyway.
The various targets didn't consistently define the unsigned
variants in any case.

3dd9ff3d84 knc.h: 
Properly pick up on ISPC_FORCE_ALIGNED_MEMORY when --opt=force-aligned-memory is used
	Fixed usage of loadunpack and packstore to use proper memory offset
	Fixed implementation of __masked_load_*() __masked_store_*() incorrectly (un)packing the lanes loaded
	Cleaned up usage of _mm512_undefined_*(), it is now mostly confined to constructor
	Minor cleanups

be2108260e Add --opt=force-aligned-memory option. 
This forces all vector loads/stores to be done assuming that the given
pointer is aligned to the vector size, thus allowing the use of sometimes
more-efficient instructions.  (If it isn't the case that the memory is
aligned, the program will fail!).

05a5a42a08 Don't force loads/stores from varying types to be unaligned. 
These should always actually be aligned in memory.
