Sometime recently the Altivec splat instructions seem to have gone south:

<http://gcc.gnu.org/bugzilla/show_bug.cgi?id=14426>

This was working a week or so ago and I was hoping to retest the example that caused me to log <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=14042> a while back (now that it is supposedly fixed). Unfortunately, I can't build even fairly simple Altivec programs with tree-ssa right now.

Both of these were broken by: 2004-02-21 Ziemowit Laski <zlaski@apple.com>

So I guess this answers a question I had -- apparently Apple doesn't have an internal (more comprehensive) Altivec test suite. Does Motorola or IBM have a test suite that could be used or would a volunteer need to build one?


It seems reasonable to expect a minimal test suite to at least:

- Call every PIM-specified function at least once, checking the output
	- Pseudo things like vec_splat
	- 'Real' instructions like vec_vspltisw
- Test error reporting for inputs (non-const arguments)
