[Dotgnu-pnet-commits] CVS: pnet/engine md_arm.h, 1.8, 1.9 md_x86.h, 1.6, 1.7 unroll_branch.c, 1.1, 1.2

[Rhys Weatherley <address@hidden>]

Update of /cvsroot/dotgnu-pnet/pnet/engine
In directory subversions:/tmp/cvs-serv25553/engine

Modified Files:
        md_arm.h md_x86.h unroll_branch.c 
Log Message:


Introduce some extra instructions for unsigned comparisons because
PPC cannot set the condition codes for both signed and unsigned
results at the same time like x86 and ARM can.
