scalar values (that ispc used to smear across the array/struct
elements). Now, initializers in variable declarations must be
{ }-delimited lists, with one element per struct member or array
element, respectively.
There were a few problems with the previous implementation of the
functionality to initialize from scalars. First, the expression
would be evaluated once per value initialized, so if it had side-effects,
the wrong thing would happen. Next, for large multidimensional arrays,
the generated code would be a long series of move instructions, rather
than loops (and this in turn made LLVM take a long time.)
While both of these problems are fixable, it's a non-trivial
amount of re-plumbing for a questionable feature anyway.
Fixes issue #50.

=== 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.)
|
|
|
|
=== 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).
