No, just the generic type (sparc or x86).

So are there any compiler flags that determine whether its for sparc or
x86? or just compiling it on AMD makes it portable to any x86?

To the best of my knowledge, Sun Studio does *NOT* support cross-compiling.
You have to use the x86 version to build x86 binaries, and the SPARC
version to build SPARC binaries.

This means that, in general, you shouldn't worry about 'portability' to a
specific platform, because by selecting a specific version of Sun Studio to
build your programs, you have implicitly picked the supported platform too.
