>>> People are running into problems with PICL on Solaris. First of all we linked with libpicl on x86 and we shouldn’t because it’s not really require here. Secondly, in some situations (like Solaris zones) PICL is not installed by default. Nevertheless it remains the only reasonable way to determine cache line sizes on SPARC (which we need to properly use BIS instructions), so we’d like to keep using it. The only solution I see is to link manually and display a warning if PICL is not installed.
