描述
This is probably a trivial issue, but compiling an ASM with the emcc options below including -s MIN_IE_VERSION=11 produces an asm that has functions that cause an exception on IE11. The one I've caught so far is Object doesn't support property or method 'startsWith' (see screenshot).
This is compiled with the latest (as of today) official docker container of emsdk. When I compiled with the same commandline a year ago (roughly), this produced a asm that ran perefectly in IE11.
It would be trivial to substitute startsWith with something like:
! c.indexOf("data:application/octet-stream;base64,")
or else include the simple MDN polyfill.
