99270 2012-10-14 13:05:34 -0700 REGRESSION(126886): Fat binary builds don't know how to handle architecture variants to which the LLInt is agnostic 2012-10-14 19:33:25 -0700 1 1 1 Unclassified WebKit JavaScriptCore 528+ (Nightly build) All All RESOLVED FIXED P2 Normal --- 90098 1 fpizlo fpizlo barraclough ddkilzer ggaren mark.lam mhahnenberg msaboff oliver oldest_to_newest 741585 0 fpizlo 2012-10-14 13:05:34 -0700 This comes up with ARMv7s, where the C++ toolchain handles it as a separate architecture and may end up compiling the code in a substantially different way, while the LLInt doesn't care. The fix for https://bugs.webkit.org/show_bug.cgi?id=90098 causes the offlineasm's knowledge of ARMv7s to be dropped, since it assumes that if the offsets are the same then the configuration is the same. That's just plain wrong, since it's the configuration index (identifying the combination of settings flags) that should be uniq'd, not the offsets. 741587 1 168588 fpizlo 2012-10-14 13:11:05 -0700 Created attachment 168588 the patch 741665 2 168588 ggaren 2012-10-14 19:08:08 -0700 Comment on attachment 168588 the patch r=me 741678 3 fpizlo 2012-10-14 19:33:25 -0700 Landed in http://trac.webkit.org/changeset/131287 168588 2012-10-14 13:11:05 -0700 2012-10-14 19:08:08 -0700 the patch fixofflineasm_1.patch text/plain 1946 fpizlo SW5kZXg6IFNvdXJjZS9KYXZhU2NyaXB0Q29yZS9DaGFuZ2VMb2cKPT09PT09PT09PT09PT09PT09 PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PQotLS0gU291 cmNlL0phdmFTY3JpcHRDb3JlL0NoYW5nZUxvZwkocmV2aXNpb24gMTMxMjY5KQorKysgU291cmNl L0phdmFTY3JpcHRDb3JlL0NoYW5nZUxvZwkod29ya2luZyBjb3B5KQpAQCAtMSwzICsxLDE1IEBA CisyMDEyLTEwLTE0ICBGaWxpcCBQaXpsbyAgPGZwaXpsb0BhcHBsZS5jb20+CisKKyAgICAgICAg UkVHUkVTU0lPTigxMjY4ODYpOiBGYXQgYmluYXJ5IGJ1aWxkcyBkb24ndCBrbm93IGhvdyB0byBo YW5kbGUgYXJjaGl0ZWN0dXJlIHZhcmlhbnRzIHRvIHdoaWNoIHRoZSBMTEludCBpcyBhZ25vc3Rp YworICAgICAgICBodHRwczovL2J1Z3Mud2Via2l0Lm9yZy9zaG93X2J1Zy5jZ2k/aWQ9OTkyNzAK KworICAgICAgICBSZXZpZXdlZCBieSBOT0JPRFkgKE9PUFMhKS4KKworICAgICAgICBUaGUgZml4 IGlzIHRvIGhhc2ggY29ucyB0aGUgb2Zmc2V0cyBiYXNlZCBvbiBjb25maWd1cmF0aW9uIGluZGV4 LCBub3QgdGhlIG9mZnNldHMKKyAgICAgICAgdGhlbXNlbHZlcy4KKworICAgICAgICAqIG9mZmxp bmVhc20vb2Zmc2V0cy5yYjoKKwogMjAxMi0xMC0xNCAgRmlsaXAgUGl6bG8gIDxmcGl6bG9AYXBw bGUuY29tPgogCiAgICAgICAgIEZpeCB0aGUgYnVpbGQgb2YgdW5pdmVyc2FsIGJpbmFyeSB3aXRo IEFSTXY3cyBvZiBKYXZhU2NyaXB0Q29yZQpJbmRleDogU291cmNlL0phdmFTY3JpcHRDb3JlL29m ZmxpbmVhc20vb2Zmc2V0cy5yYgo9PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09 PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09Ci0tLSBTb3VyY2UvSmF2YVNjcmlwdENvcmUv b2ZmbGluZWFzbS9vZmZzZXRzLnJiCShyZXZpc2lvbiAxMzEyNjIpCisrKyBTb3VyY2UvSmF2YVNj cmlwdENvcmUvb2ZmbGluZWFzbS9vZmZzZXRzLnJiCSh3b3JraW5nIGNvcHkpCkBAIC02MCw3ICs2 MCw3IEBAIGVuZAogCiAjCiAjIG9mZnNldHNBbmRDb25maWd1cmF0aW9uSW5kZXgoYXN0LCBmaWxl KSAtPgotIyAgICAge1tvZmZzZXRzLCBpbmRleF0sIC4uLn0KKyMgICAgIFtbb2Zmc2V0cywgaW5k ZXhdLCAuLi5dCiAjCiAjIFBhcnNlcyB0aGUgb2Zmc2V0cyBmcm9tIGEgZmlsZSBhbmQgcmV0dXJu cyBhIGxpc3Qgb2Ygb2Zmc2V0cyBhbmQgdGhlCiAjIGluZGV4IG9mIHRoZSBjb25maWd1cmF0aW9u IHRoYXQgaXMgdmFsaWQgaW4gdGhpcyBidWlsZCB0YXJnZXQuCkBAIC0xNTQsMTYgKzE1NCwxOSBA QCBkZWYgb2Zmc2V0c0FuZENvbmZpZ3VyYXRpb25JbmRleChmaWxlKQogICAgICAgICAgICAgICAg ICAgICB8IGRhdGEgfAogICAgICAgICAgICAgICAgICAgICBvZmZzZXRzIDw8IHJlYWRJbnQoZW5k aWFubmVzcywgZGF0YSkKICAgICAgICAgICAgICAgICB9Ci0gICAgICAgICAgICAgICAgaWYgbm90 IHJlc3VsdC5oYXNfa2V5PyhvZmZzZXRzKQotICAgICAgICAgICAgICAgICAgICByZXN1bHRbb2Zm c2V0c10gPSBpbmRleAotICAgICAgICAgICAgICAgIGVuZAorICAgICAgICAgICAgICAgIHJlc3Vs dFtpbmRleF0gPSBvZmZzZXRzCiAgICAgICAgICAgICB9CiAgICAgICAgIGVuZAogICAgIH0KICAg ICAKICAgICByYWlzZSBNaXNzaW5nTWFnaWNWYWx1ZXNFeGNlcHRpb24gdW5sZXNzIHJlc3VsdC5s ZW5ndGggPj0gMQogICAgIAotICAgIHJlc3VsdAorICAgICMgcmVzdWx0IGlzIHtpbmRleDE9Pm9m ZnNldHMxLCBpbmRleDI9Pm9mZnNldHMyfSBidXQgd2Ugd2FudCB0byByZXR1cm4KKyAgICAjIFtb b2Zmc2V0czEsIGluZGV4MV0sIFtvZmZzZXRzMiwgaW5kZXgyXV0uCisgICAgcmV0dXJuIHJlc3Vs dC5tYXAgeworICAgICAgICB8IHBhaXIgfAorICAgICAgICBwYWlyLnJldmVyc2UKKyAgICB9CiBl bmQKIAogIwo=
