38235e2eec move JSOP_DOUBLE impl to, er, JSOP_DOUBLE (wtf?) 2008-07-06 09:33:13 -04:00

2d307b4b59 Implement JSOP_DOUBLE. 2008-07-06 07:28:36 -04:00

100f4ea5e0 Added support for semi-stable loop variables. Compiling for(...) q += 2.5; is ridiculously difficult because it flip-flops between int and double. Add support to promote integer values to doubles at the loop tail if at loop entry we expect a double. Since this isn't possible the other way around, we have to get luck that we catch a path into the loop where q is already double. For this we add 3 trigger points (10, 13, 37). We will try three times to record a trace at those iteration counts of a loop. If none succeed the loop is blacklisted. This probably needs more tuning down the road. 2008-07-05 23:21:53 -07:00

a48c36fae3 Added FuncFilter from tamarin core (not part of nanojit yet since its slightly VM dependant). 2008-07-05 22:20:35 -07:00

0245a6ba7c Believe it or not NEG can actually overflow the int32 range, so add an overflow bailout. This will only trap for -0x80000000. 2008-07-05 19:25:38 -07:00

48e459ba73 Added blacklisting of recording points where we failed to complete a trace (overly aggressive at this point, needs tuning, we want to try several times for each point.) 2008-07-05 19:15:00 -07:00

19152ffb1f Signal error from the boxing/unboxing using magic cookies since gcc seems to very seriously object to the use of uint64 return values during a fastcall (horribly inefficient code). 2008-07-05 16:28:03 -07:00

ba7e66df92 Code generators to access object slots and native code callouts (builtins) for boxing doubles and ints. Ints have to be boxed through a native code helper on read and write (BoxInt32 and UnboxInt32), because we sometimes have to cast internally to double to store 32-bit values. We don't want a separate trace in this case, so we have to do this inline in a helper. Also a couple of modifications to shaver's code. Always make sure to check types (JSOP_NEG). 2008-07-05 11:35:55 -07:00

2df2214a9e Introduce asInt and asDouble to check for the type of values based on the actual value since some 32-bit integers hide out in doubles. 2008-07-04 23:53:29 -07:00
Andreas Gal
cef5e9becc Make trace-code 32-bit clean and extend interpreter state to carry the current context (cx). The recorder still has to record a 31-bit int path through the loop, but the emitted code is able to stay in the tree even if values bump over to 32-bit ints. 2008-07-04 16:24:42 -07:00
