PatchSet 5089 
Date: 2004/08/22 13:31:24
Author: guilhem
Branch: HEAD
Tag: (none) 
Log:
Fixed double/float to int conversion on sparc/jit.

        * config/sparc/jit-icode.h, config/i386/jit-icode.h,
        config/alpha/jit-icode.h, config/arm/jit-icode.h,
        config/m68k/jit-icode.h
        (HAVE_cvt_double_int_ieee, HAVE_cvt_float_int_ieee): New define
        symbols.

        * kaffe/kaffevm/jit/icode.c
        (cvt_double_int): New JIT codelet to use non Java-compatible
        floating point to integer converting instruction.
        (cvt_float_int): New JIT codelet to use non Java-compatible
        floating point to integer converting instruction.

        * test/internal/TypeConversion.java: Check for NaN (float or
        double) to int conversion.

        * test/internal/jitBasic.c: Fixed a memory overreading.
