Hi v8-dev,
I test some code like that:
function test(obj)
{
return obj.x;
}
var obj = {x:1};
test(obj);
test(obj);
obj.x;
obj.x;
and add --trace-ic, v8 output inline log:
[LoadIC in ~+116 at test.js:7 (0->.) #test]
[LoadIC in ~+140 at test.js:7 (0->.) #obj]
[LoadIC in ~test+38 at test.js:3 (0->.) #x]
[LoadIC in ~+179 at test.js:8 (.->1) #test]
[LoadIC in ~+203 at test.js:8 (.->1) #obj]
[LoadIC in ~test+38 at test.js:3 (.->1) #x]
[LoadIC in ~+259 at test.js:10 (0->.) #x]
[LoadIC in ~+294 at test.js:11 (0->.) #x]
it seems that direct call 'obj.x', inline stat always is '0'.
but in function test, it will change to (0->.->1);
so what's different between this?
Thanks in advance.
