# commit a8de15f66a51d273cefa07eed0d8fd2952e92387
# Author: Andrew Kelley <andrew@ziglang.org>
# Date:   Mon Apr 24 13:29:42 2023 -0700
#
#     update zig1.wasm
#
#     Needed due to the compiler depending on standard library APIs such as
#     ArrayList that contain `@memset` and `@memcpy` calls in them. The number
#     of parameters changed, so this is necessary for the compiler to build.

# commit 22c6b6c9a9378aaca75c83c2182a6d94298f6bc2
# Author: Matthew Lugg <mlugg@mlugg.co.uk>
# Date:   2023-06-14T03:09:23+03:00
#
#     Update zig1.wasm
#
#     This is needed in order to remove math.{min,max} from std in favour of
#     the builtins, since the builtins need the behavior fix from the previous
#     commit.
#
#     Note from Andrew: I updated this commit with zig1.wasm built by me.
