05bd86e2ed use upper 32 bits of mask in pickRegisterTarget when picking register for high word; set Target::Impossible to 5 since 4 is a valid cost 2009-01-11 16:42:41 -07:00

5a76277b84 remove dead buddies from values so they don't accumulate without bound; when resolving sites, avoid picking those which belong to other values; various bugfixes 2009-01-11 15:53:51 -07:00
Joel Dice
e3976e66d3 avoid using all registers when marshalling sites, since we need at least one register free for memory-to-memory moves; various bugfixes 2009-01-11 11:48:02 -07:00
Joel Dice
54ad7c4e98 tolerate ConstantValue attributes on non-static fields, since the compiler ensures that they are initialized in any constructors for that class (i.e., the VM does not need to do anything special to initialize them) 2009-01-10 12:25:52 -07:00

Joel Dice
4717e94fa3 remove value buddies after setting sites to junction sites, not after populating junction sites 
This mirrors how snapshots are captured and restored for branch events.
Also, switch back to resolving junction sites before capturing fork
snapshots so we capture the true state of each value immediately before
the branch.

Joel Dice
8b2a6f85fc remove divideCR and remainderCR 
This forces the compiler to explicitly move the constant operand into
a register, avoiding the possibility that AX or DX might be unavailable
when the assembler needs them.

db3434001f Use mingw32 'strip' when compiling for Windows. 
This fixes the error when using /usr/bin/strip on
Ubuntu 8.10 when it believes the target file is of
an "ambiguous format".
