I download and tried it today.
It compiles my project but "suncc" is even slower then "gcc" which is famous for its leisureliness. I just -xO1 which i thought should do no optimizations. I have a lot of inline declared C functions. Is there a way to disable the inlining or anything else to make it compile faster.
-xO1 does basic optimizations. According to the Sun documentation:
On x86 platforms:
-xO1 Preloads arguments from memory, cross-jumping
(tail-merging), as well as the single pass of the
default optimization.
If you don't want any optimization, remove any -xOn options.
