- In the ispc-generated header files, a #define now indicates which compilation target
was used.
- The examples use utility routines from the new file examples/cpuid.h to check the
system's CPU's capabilities to see if it supports the ISA that was used for
compiling the example code and print error messages if things aren't going to
work...
Fixes bug #55. A number of tests were crashing on Windows due to the task
launch code using alloca to allocate space for the tasks' parameters. On
Windows, the stack isn't generally big enough for this to be a good idea.
Also added an alignment parmaeter to ISPCMalloc() to pass the alignment
requirement along.
Link the appropriate clang libraries to make the preprocessor
stuff work on Windows builds. Also updated the solution files
for the examples to stop using cl.exe for preprocessing but to
just call ispc directly. Finishes fixes for issue #32.
were expecting vector-width-aligned pointers where in point of fact,
there's no guarantee that they would have been in general.
Removed the aligned memory allocation routines from some of the examples;
they're no longer needed.
No perf. difference on Core2/Core i5 CPUs; older CPUs may see some
regressions.
Still need to update the documentation for this change and finish reviewing
alignment issues in Load/Store instructions generated by .cpp files.
