I was writing real-time signal processing software for POWER as recently as three years ago. I'm not even aware that was IBM's position, and they were our partners on the venture.
That said, it really didn't matter because all our software had to build and run on x86-64 anyway, so all the endian-specific code was wrapped in preprocessor directives. We could have changed the endianness with a single makefile change.
- bandrami 12y agoI'm not even aware that was IBM's position Yeah, I said it badly. IBM wouldn't guarantee Apple that Power would always support BE, so Apple pushed (or tried to) developers not to assume that.
- vonmoltke 12y agoThat makes sense. IBM knew we were focused on the POWER7 blades and that our backup plan was their Intel blades, so they probably figured the warning wouldn't be relevant to us.
