Firstly, Thanks for your help.
I find that describe() function was call only in the
Interpreter::dumpRegisters function, and dumpCallFrame will call the
dumpRegisters , but i cann't find the place that call the dumpCallFrame .

I would still suggest you look at the tag/payload ordering. If it's flipped,
you'll see this error.
Try using the describe() function in jsc in addition to using print(). That
will do a dump of the internal structure of the JSValue. If it's flipped, then
you'll know where to look.

What is the endianness of your platform? I think that the big endian code in
JavaScriptCore may have rotted.
This smells to me like the tag and payload getting flipped around, which might
happen if there are parts of the code that are assuming little endian and your
hardware is big endian.

Hi,
I have test with follow case, and cann't get correct reslut. I find that
Floating-point operations is error, and I don't know where shold start to
fixed this question. so if anybody can give some information for which function
i should to check.
Any help explaining this would be much appreciated!
My Compiler:MSVS
ARCH:SH4
Feature:JIT
Javascript code of test case
function jitTestCode() {
var tmp = -1*0;
debug("tmp:" + tmp);
var result = tmp + 1;
debug("The result should be 1,result:" + result); //print
var item1 = result - 1;
debug("The item1 should be 0,item1:" + item1); //print
var item2 = result - 2;
debug("The item2 should be -1,item2:" + item2); //print
}
And the log information are:
[CONSOLE-DEBUG]Message is :'tmp:0'
[CONSOLE-DEBUG]Message is :'The result should be 1,result:0.0078125'
[CONSOLE-DEBUG]Message is :'The item1 should be 0,item1:0'
[CONSOLE-DEBUG]Message is :'The item2 should be -1,item2:-0.0078125'
