Hello Kate,
which compiler and which S32DS you mean?
The offline documentation for GCC is available here (the same way for ARM, but there is ARM instead of Power):
"<S32DS_Power...>\Cross_Tools\powerpc-eabivle-4_9\powerpc-eabivle\share\docs\pdf"
"<S32DS_Power...>\Cross_Tools\powerpc-eabivle-4_9\powerpc-eabivle\share\docs\pdf\gcc\"
Some useful information can be found in the gcc release notes:
"<S32DS_Power...>\Cross_Tools\powerpc-eabivle-4_9\releasenotes.pdf"
Regards,
Martin
