We do an execute() above it. It is asserting that if we need a watchpoint (i.e. the best proven structure was not the current structure) then it must be the future possible structure. But while that may have been true before execute(), it won't be true after. 946987 2 215992 fpizlo 2013-11-04 20:30:25 -0800 Created attachment 215992 the patch 947014 3 215992 ggaren 2013-11-04 21:36:09 -0800 Comment on attachment 215992 the patch r=me 947017 4 fpizlo 2013-11-04 21:40:08 -0800 Landed in http://trac.webkit.org/changeset/158646 215992 2013-11-04 20:30:25 -0800 2013-11-04 21:36:08 -0800 the patch blah.patch text/plain 2362 fpizlo SW5kZXg6IFNvdXJjZS9KYXZhU2NyaXB0Q29yZS9DaGFuZ2VMb2cKPT09PT09PT09PT09PT09PT09 PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PQotLS0gU291 cmNlL0phdmFTY3JpcHRDb3JlL0NoYW5nZUxvZwkocmV2aXNpb24gMTU4NjM5KQorKysgU291cmNl L0phdmFTY3JpcHRDb3JlL0NoYW5nZUxvZwkod29ya2luZyBjb3B5KQpAQCAtMSwzICsxLDI0IEBA CisyMDEzLTExLTA0ICBGaWxpcCBQaXpsbyAgPGZwaXpsb0BhcHBsZS5jb20+CisKKyAgICAgICAg aW50ZXJuYWwtanMtdGVzdHMueWFtbC9PY3RhbmUvc3RyZXNzLXRlc3RzL3BkZmpzLmpzLmRlZmF1 bHQ6IEFTU0VSVElPTiBGQUlMRUQ6IG1fc3RhdGUuZm9yTm9kZShjaGlsZCkubV9mdXR1cmVQb3Nz aWJsZVN0cnVjdHVyZS5pc1N1YnNldE9mKFN0cnVjdHVyZVNldChzdHJ1Y3R1cmUpKSBhdCBERkdD b25zdGFudEZvbGRpbmdQaGFzZS5jcHA6MjQ5CisgICAgICAgIGh0dHBzOi8vYnVncy53ZWJraXQu b3JnL3Nob3dfYnVnLmNnaT9pZD0xMjM3NzgKKworICAgICAgICBSZXZpZXdlZCBieSBOT0JPRFkg KE9PUFMhKS4KKyAgICAgICAgCisgICAgICAgIFRoaXMgYXNzZXJ0aW9uIHdhcyBqdXN0IHdyb25n OiBlZSBkbyBhbiBleGVjdXRlKCkgYWJvdmUgdGhlIGFzc2VydGlvbi4gVGhlIGFzc2VydGlvbgor ICAgICAgICBpcyBhc3NlcnRpbmcgdGhhdCBpZiB3ZSBuZWVkIGEgd2F0Y2hwb2ludCAoaS5lLiB0 aGUgYmVzdCBwcm92ZW4gc3RydWN0dXJlIHdhcyBub3QgdGhlCisgICAgICAgIGN1cnJlbnQgc3Ry dWN0dXJlKSB0aGVuIGl0IG11c3QgYmUgdGhlIGZ1dHVyZSBwb3NzaWJsZSBzdHJ1Y3R1cmUuICBC dXQgd2hpbGUgdGhhdCBtYXkKKyAgICAgICAgaGF2ZSBiZWVuIHRydWUgYmVmb3JlIGV4ZWN1dGUo KSwgaXQgd29uJ3QgYmUgdHJ1ZSBhZnRlciBpZiB0aGUgUHV0QnlJZCB3YXMgYQorICAgICAgICB0 cmFuc2l0aW9uLiBPZiBjb3Vyc2UsIHRoaXMgY2FuIG9ubHkgaGFwcGVuIGluIHRoZSBjb25jdXJy ZW50IEpJVCBpbiB3aGljaCBjYXNlIHRoZQorICAgICAgICBjb2RlIHdvdWxkIGJlIGludmFsaWRh dGVkIGFueXdheSBzaW5jZSB3ZSB3b3VsZCBvbmx5IHRyYW5zZm9ybSB0aGUgY29kZSBpbiBhIHdh eSB0aGF0CisgICAgICAgIGxldmVyYWdlZCB0aGUgbGFjayBvZiBhIHRyYW5zaXRpb24gaWYgd2Ug aW5zZXJ0ZWQgYSB3YXRjaHBvaW50LCBpbiB3aGljaCBjYXNlIHdlCisgICAgICAgIHdvdWxkIHJl YWxpemUgdGhhdCB0aGUgd2F0Y2hwb2ludCBoYWQgYmVlbiBmaXJlZCBkdXJpbmcgY29tcGlsYXRp b24uCisgICAgICAgIAorICAgICAgICBTaW5jZSB0aGlzIHJlcXVpcmVzIGNvbmN1cnJlbnQgSklU IGF3ZXNvbWVuZXNzLCBJIGRvbid0IGtub3cgaG93IHRvIHRlc3QgaXQuCisKKyAgICAgICAgKiBk ZmcvREZHQ29uc3RhbnRGb2xkaW5nUGhhc2UuY3BwOgorICAgICAgICAoSlNDOjpERkc6OkNvbnN0 YW50Rm9sZGluZ1BoYXNlOjpmb2xkQ29uc3RhbnRzKToKKwogMjAxMy0xMS0wNCAgRmlsaXAgUGl6 bG8gIDxmcGl6bG9AYXBwbGUuY29tPgogCiAgICAgICAgIERGRyBOZXdBcnJheS9OZXdBcnJheUJ1 ZmZlciBzaG91bGRuJ3QgYmUgY29uc3RydWN0aW5nIHdpdGggbmVnYXRpdmUgaW5kZXhpbmcKSW5k ZXg6IFNvdXJjZS9KYXZhU2NyaXB0Q29yZS9kZmcvREZHQ29uc3RhbnRGb2xkaW5nUGhhc2UuY3Bw Cj09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09 PT09PT09PT09PT0KLS0tIFNvdXJjZS9KYXZhU2NyaXB0Q29yZS9kZmcvREZHQ29uc3RhbnRGb2xk aW5nUGhhc2UuY3BwCShyZXZpc2lvbiAxNTg2MzkpCisrKyBTb3VyY2UvSmF2YVNjcmlwdENvcmUv ZGZnL0RGR0NvbnN0YW50Rm9sZGluZ1BoYXNlLmNwcAkod29ya2luZyBjb3B5KQpAQCAtMjQ2LDcg KzI0Niw2IEBAIHByaXZhdGU6CiAgICAgICAgICAgICAgICAgZWxpbWluYXRlZCA9IHRydWU7CiAg ICAgICAgICAgICAgICAgCiAgICAgICAgICAgICAgICAgaWYgKG5lZWRzV2F0Y2hwb2ludCkgewot ICAgICAgICAgICAgICAgICAgICBBU1NFUlQobV9zdGF0ZS5mb3JOb2RlKGNoaWxkKS5tX2Z1dHVy ZVBvc3NpYmxlU3RydWN0dXJlLmlzU3Vic2V0T2YoU3RydWN0dXJlU2V0KHN0cnVjdHVyZSkpKTsK ICAgICAgICAgICAgICAgICAgICAgbV9pbnNlcnRpb25TZXQuaW5zZXJ0Tm9kZSgKICAgICAgICAg ICAgICAgICAgICAgICAgIGluZGV4SW5CbG9jaywgU3BlY05vbmUsIFN0cnVjdHVyZVRyYW5zaXRp b25XYXRjaHBvaW50LCBjb2RlT3JpZ2luLAogICAgICAgICAgICAgICAgICAgICAgICAgT3BJbmZv KHN0cnVjdHVyZSksIGNoaWxkRWRnZSk7Cg==
