Subject: Get about 1/3rd of the tests running with MEMORY64=1, but the code noise level added... 
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=22f9ca64dbc0dabda72f8b1b5305c8d846d8e7a7;p=thirdparty%2Fsqlite.git

Get about 1/3rd of the tests running with MEMORY64=1, but the code noise level added by the BigInt/Number discrepancy is making this very unattractive. There are apparently irreconcilable differences between MEMORY64=1 and 2, in that they have different argument type expectations for methods such as WebAssembly.Table.get(), where MEMORY64=1 requires a BigInt a MEMORY64=2 requires a Number. We have no way to make that distinction from the JS code, and don't know what other APIs are affected by that quirk.
