Sun Studio 12 C compiler for Linux is so slow

Question

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.

Answer 1

-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.
