130614 2014-03-21 13:41:02 -0700 Refactoring the BytecodeGenerator to use a BytecodeGeneratorVector. 2014-03-21 13:54:49 -0700 1 1 1 Unclassified WebKit JavaScriptCore 528+ (Nightly build) Unspecified Unspecified RESOLVED INVALID P2 Normal --- 1 mark.lam mark.lam ggaren oliver oldest_to_newest 993304 0 mark.lam 2014-03-21 13:41:02 -0700 Introducing a BytecodeGeneratorVector for the purpose of pointing out the way the BytecodeGenerator uses element in those vectors i.e. it can retain references to elements in the vector while new elements are added, or some elements are removed. The BytecodeGeneratorVector is implemented as a SegmentedVector. The BytecodeGenerator will now use the BytecodeGeneratorVector instead of the SegmentedVector. 993305 1 227485 mark.lam 2014-03-21 13:46:09 -0700 Created attachment 227485 the patch. 993308 2 mark.lam 2014-03-21 13:54:41 -0700 Fil pointed out that the use of SegmentedVector already adequately indicate the information about how the BytecodeGenerator uses those vector elements. At this point, there's no added benefit to doing this. So, I'll retract the patch. 227485 2014-03-21 13:46:09 -0700 2014-03-21 13:54:49 -0700 the patch. bug-130614.patch text/plain 3101 mark.lam SW5kZXg6IFNvdXJjZS9KYXZhU2NyaXB0Q29yZS9DaGFuZ2VMb2cKPT09PT09PT09PT09PT09PT09 PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PQotLS0gU291 cmNlL0phdmFTY3JpcHRDb3JlL0NoYW5nZUxvZwkocmV2aXNpb24gMTY2MDk1KQorKysgU291cmNl L0phdmFTY3JpcHRDb3JlL0NoYW5nZUxvZwkod29ya2luZyBjb3B5KQpAQCAtMSwzICsxLDE5IEBA CisyMDE0LTAzLTIxICBNYXJrIExhbSAgPG1hcmsubGFtQGFwcGxlLmNvbT4KKworICAgICAgICBS ZWZhY3RvcmluZyB0aGUgQnl0ZWNvZGVHZW5lcmF0b3IgdG8gdXNlIGEgQnl0ZWNvZGVHZW5lcmF0 b3JWZWN0b3IuCisgICAgICAgIDxodHRwczovL3dlYmtpdC5vcmcvYi8xMzA2MTQ+CisKKyAgICAg ICAgUmV2aWV3ZWQgYnkgTk9CT0RZIChPT1BTISkuCisKKyAgICAgICAgSW50cm9kdWNpbmcgYSBC eXRlY29kZUdlbmVyYXRvclZlY3RvciBmb3IgdGhlIHB1cnBvc2Ugb2YgcG9pbnRpbmcgb3V0Cisg ICAgICAgIHRoZSB3YXkgdGhlIEJ5dGVjb2RlR2VuZXJhdG9yIHVzZXMgZWxlbWVudCBpbiB0aG9z ZSB2ZWN0b3JzIGkuZS4gaXQgY2FuCisgICAgICAgIHJldGFpbiByZWZlcmVuY2VzIHRvIGVsZW1l bnRzIGluIHRoZSB2ZWN0b3Igd2hpbGUgbmV3IGVsZW1lbnRzIGFyZSBhZGRlZCwKKyAgICAgICAg b3Igc29tZSBlbGVtZW50cyBhcmUgcmVtb3ZlZC4gIFRoZSBCeXRlY29kZUdlbmVyYXRvclZlY3Rv ciBpcyBpbXBsZW1lbnRlZAorICAgICAgICBhcyBhIFNlZ21lbnRlZFZlY3Rvci4gIFRoZSBCeXRl Y29kZUdlbmVyYXRvciB3aWxsIG5vdyB1c2UgdGhlCisgICAgICAgIEJ5dGVjb2RlR2VuZXJhdG9y VmVjdG9yIGluc3RlYWQgb2YgdGhlIFNlZ21lbnRlZFZlY3Rvci4KKworICAgICAgICAqIGJ5dGVj b21waWxlci9CeXRlY29kZUdlbmVyYXRvci5oOgorCiAyMDE0LTAzLTIxICBGaWxpcCBQaXpsbyAg PGZwaXpsb0BhcHBsZS5jb20+CiAKICAgICAgICAgQ29uc3RhbnRzIGZvbGRlZCBieSBERkc6OkJ5 dGVDb2RlUGFyc2VyIHNob3VsZCBub3QgYmUgZGVhZC4KSW5kZXg6IFNvdXJjZS9KYXZhU2NyaXB0 Q29yZS9ieXRlY29tcGlsZXIvQnl0ZWNvZGVHZW5lcmF0b3IuaAo9PT09PT09PT09PT09PT09PT09 PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09Ci0tLSBTb3Vy Y2UvSmF2YVNjcmlwdENvcmUvYnl0ZWNvbXBpbGVyL0J5dGVjb2RlR2VuZXJhdG9yLmgJKHJldmlz aW9uIDE2NjA2MykKKysrIFNvdXJjZS9KYXZhU2NyaXB0Q29yZS9ieXRlY29tcGlsZXIvQnl0ZWNv ZGVHZW5lcmF0b3IuaAkod29ya2luZyBjb3B5KQpAQCAtMTU1LDYgKzE1NSwxNCBAQCBuYW1lc3Bh Y2UgSlNDIHsKICAgICAgICAgVHJ5RGF0YSogdHJ5RGF0YTsKICAgICB9OwogCisgICAgLy8gVGhl IEJ5dGVjb2RlR2VuZXJhdG9yVmVjdG9yIGlzIGltcGxlbWVudGVkIHVzaW5nIGEgU2VnbWVudGVk VmVjdG9yIGJlY2F1c2UKKyAgICAvLyB0aGUgQnl0ZWNvZGVHZW5lcmF0b3IgbWF5IHJldGFpbiBw b2ludGVycyB0byBlbGVtZW50cyBpbiB0aGUgdmVjdG9yIHdoaWxlCisgICAgLy8gaXQgcHVzaGVz IGFuZCBwb3BzIG1vcmUgZWxlbWVudHMuIFRoZSBTZWdtZW50ZWRWZWN0b3IgZW5zdXJlcyB0aGF0 IHRoZQorICAgIC8vIHJldGFpbmVkIHBvaW50ZXJzIGRvIG5vdCBnZXQgaW52YWxpZGF0ZWQgYnkg dGhlIHZlY3RvciBiZWluZyByZXNpemVkLgorICAgIHRlbXBsYXRlPHR5cGVuYW1lIFQsIHNpemVf dCBpbmxpbmVDYXBhY2l0eSA9IDA+CisgICAgY2xhc3MgQnl0ZWNvZGVHZW5lcmF0b3JWZWN0b3Ig OiBwdWJsaWMgU2VnbWVudGVkVmVjdG9yPFQsIGlubGluZUNhcGFjaXR5PiB7CisgICAgfTsKKwog ICAgIGNsYXNzIEJ5dGVjb2RlR2VuZXJhdG9yIHsKICAgICAgICAgV1RGX01BS0VfRkFTVF9BTExP Q0FURUQ7CiAgICAgcHVibGljOgpAQCAtNjMzLDEwICs2NDEsMTAgQEAgbmFtZXNwYWNlIEpTQyB7 CiAgICAgICAgIFJlZ2lzdGVySUQqIG1fZW1wdHlWYWx1ZVJlZ2lzdGVyOwogICAgICAgICBSZWdp c3RlcklEKiBtX2dsb2JhbE9iamVjdFJlZ2lzdGVyOwogICAgICAgICBWZWN0b3I8SWRlbnRpZmll ciwgMTY+IG1fd2F0Y2hhYmxlVmFyaWFibGVzOwotICAgICAgICBTZWdtZW50ZWRWZWN0b3I8UmVn aXN0ZXJJRCwgMzI+IG1fY29uc3RhbnRQb29sUmVnaXN0ZXJzOwotICAgICAgICBTZWdtZW50ZWRW ZWN0b3I8UmVnaXN0ZXJJRCwgMzI+IG1fY2FsbGVlUmVnaXN0ZXJzOwotICAgICAgICBTZWdtZW50 ZWRWZWN0b3I8UmVnaXN0ZXJJRCwgMzI+IG1fcGFyYW1ldGVyczsKLSAgICAgICAgU2VnbWVudGVk VmVjdG9yPExhYmVsLCAzMj4gbV9sYWJlbHM7CisgICAgICAgIEJ5dGVjb2RlR2VuZXJhdG9yVmVj dG9yPFJlZ2lzdGVySUQsIDMyPiBtX2NvbnN0YW50UG9vbFJlZ2lzdGVyczsKKyAgICAgICAgQnl0 ZWNvZGVHZW5lcmF0b3JWZWN0b3I8UmVnaXN0ZXJJRCwgMzI+IG1fY2FsbGVlUmVnaXN0ZXJzOwor ICAgICAgICBCeXRlY29kZUdlbmVyYXRvclZlY3RvcjxSZWdpc3RlcklELCAzMj4gbV9wYXJhbWV0 ZXJzOworICAgICAgICBCeXRlY29kZUdlbmVyYXRvclZlY3RvcjxMYWJlbCwgMzI+IG1fbGFiZWxz OwogICAgICAgICBMYWJlbFNjb3BlU3RvcmUgbV9sYWJlbFNjb3BlczsKICAgICAgICAgUmVmUHRy PFJlZ2lzdGVySUQ+IG1fbGFzdFZhcjsKICAgICAgICAgaW50IG1fZmluYWxseURlcHRoOwpAQCAt NjUwLDcgKzY1OCw3IEBAIG5hbWVzcGFjZSBKU0MgewogICAgICAgICBWZWN0b3I8c3RkOjpwYWly PFJlZlB0cjxSZWdpc3RlcklEPiwgY29uc3QgRGVjb25zdHJ1Y3Rpb25QYXR0ZXJuTm9kZSo+PiBt X2RlY29uc3RydWN0ZWRQYXJhbWV0ZXJzOwogICAgICAgICAKICAgICAgICAgVmVjdG9yPFRyeVJh bmdlPiBtX3RyeVJhbmdlczsKLSAgICAgICAgU2VnbWVudGVkVmVjdG9yPFRyeURhdGEsIDg+IG1f dHJ5RGF0YTsKKyAgICAgICAgQnl0ZWNvZGVHZW5lcmF0b3JWZWN0b3I8VHJ5RGF0YSwgOD4gbV90 cnlEYXRhOwogCiAgICAgICAgIGludCBtX2ZpcnN0Q29uc3RhbnRJbmRleDsKICAgICAgICAgaW50 IG1fbmV4dENvbnN0YW50T2Zmc2V0Owo=
