Joel Dice	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
Joel Dice	04bc58fd95	reorder code in MemorySite::release so we can use low->size before it is overwritten	2009-01-11 16:24:25 -07:00
Joel Dice	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	7f4bd51464	don't use trySteal when moving sites between buddies	2008-12-13 13:54:26 -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.	2008-12-13 12:59:02 -07:00

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.	2008-12-11 18:08:16 -07:00
Joel Dice	aa7b47eec4	fix merge confict fallout in heapdump.cpp	2008-12-04 14:35:25 -07:00
