=== v1.0.3 === (not yet released)
|
|
|
|
In initializer expressions with variable declarations, it is no longer
|
|
legal to initialize arrays and structs with single scalar values that then
|
|
initialize their members; they now must be initialized with initializer
|
|
lists in braces (or initialized after of the initializer with a loop over
|
|
array elements, etc.)
|
|
|
|
Added another shuffle() function to the standard library:
|
|
"<type> shuffle(<type> v0, <type> v1, int permute)", where the permutation
|
|
vector indexes over the concatenation of the two vectors (e.g. the value
|
|
0 corresponds to the first element of v0, the value 2*programCount-1
|
|
corresponds to the last element of v1, etc.)
|
|
|
|
=== v1.0.2 === (1 July 2011)
|
|
|
|
Floating-point hexidecimal constants are now parsed correctly on Windows
|
|
(fixes issue #16).
|
|
|
|
SSE2 is now the default target if --cpu=atom is given in the command line
|
|
arguments and another target isn't explicitly specified.
|
|
|
|
The standard library now provides broadcast(), rotate(), and shuffle()
|
|
routines for efficient communication between program instances.
|
|
|
|
The MSVC solution files to build the examples on Windows now use
|
|
/fpmath:fast when building.

|
=== v1.0.1 === (24 June 2011)
|
|
|
|
ispc no longer requires that pointers to memory that are passed in to ispc
|
|
have alignment equal to the targets vector width; now alignment just has to
|
|
be the regular element alignment (e.g. 4 bytes for floats, etc.) This
|
|
change also fixed a number of cases where it previously incorrectly
|
|
generated aligned load/store instructions in cases where the address wasn't
|
|
actually aligned (even if the base address passed into ispc code was).
