[Sablevm-developer] problem with divisions, float, double

[Fabien R. <re...@ne...>]

Hello,

With Arith.java I have some problem with numbers :
[verbose class: loading "Arith"]
iadd
[verbose class: loading "java/lang/Integer"]
[verbose class: loading "java/lang/Number"]
        = 4
isub
        = 2
imul
        = 3
idiv
        = 3
irem
        = 0
ineg
        = -3
ladd
[verbose class: loading "java/lang/Long"]
        = 4
lsub
        = 2
lmul
        = 3
ldiv
        = 3
lrem
        = 0
lneg
        = -3
fadd
[verbose class: loading "java/lang/Float"]
[verbose class: loading "java/lang/Double"]
        = 3.0
fsub
        = 3.0
fmul
        = 0.0

Kaffe too has problems (crashs when there is a double)
