Description
Read sizeof(half) bytes of data from address (p +
offset). The data read is interpreted as a half value.
The half value is converted to a float value and the float value is returned. The
read address computed as (p + offset) must be
16-bit aligned.
Notes
Vector Data Load and Store Functions allow you to read and write vector types from a pointer to memory.
The suffix n in the function names
(i.e. vloadn, vstoren etc.)
represent n-element
vectors, where n = 2, 3, 4, 8 or 16.
The results of vector data
load and store functions are undefined if the address being read from or written to is
not correctly aligned. The pointer argument p can be a pointer to
global,
local, or
private
memory for store functions. The pointer argument
p can be a pointer to global, local,
constant or private memory for load functions.
NOTE: The vector data load and store functions variants that take pointer arguments which point to the generic address space are also supported.
