Re: [Dotgnu-pnet] [patch #6799] libJIT 1.2.5 + / 1.2 1/2 Release (code name: libJIT-ON-TESTOSTERONE)

[Boris Manojlovic]

Hello,

this patch is NOT serious patch as it is just cosmetics to be able compiling it on x86_64 but anyway it compiles :) and
it of course seg fault under dpas test cases.. 


small part of debug....

optimization)
       * Fast liveness analysis (level 2 of optimization)
       * Dead-code elimination (level 4 of optimization)
       * Full liveness analysis (level 3, 4 of optimization)
       * Linear scan register allocator algorithm (level 2)
       * Bin packing register allocator algorithm (level 3, 4)
