[rvm-core] Should we remove pre-pass instruction scheduling?

[Erik B. <eri...@gm...>]

Hi,

the source tree currently contains code for pre-pass instruction scheduling in the org.jikesrvm.compilers.opt.instrsched package. The code is deactivated by default on PPC and not used at all on IA32. AFAIK it was never switched on by default in any public version of Jikes RVM.

I'm not sure if the code ever worked; it certainly doesn't work right now. Even if the code is updated to work with current CompilerPhase infrastructure, it fails later in OperatorClass.

Should we remove the phase or is there anybody who could commit to do the work to fix it?


Kind regards,

Erik Brangs
