;; Test embedding wasm and wat files into JS by replacing existing embedded modules.

;; Existing embedded modules will be replaced:
;; RUN: echo "good1(new Uint8Array([0x00, 0x61, 0x73, 0x6d, 0x01, 0x00, 0x00, 0x00, 0x00, 0x01, 0x2a]));" > %t.js

;; Non-wasm arrays are ignored:
;; RUN: echo "bad(new Uint8Array([0x00, 0xff, 0x73, 0x6d, 0x01]));" >> %t.js

;; Add a second valid embedded module without new Uint8Array:
;; RUN: echo "good2([0x00, 0x61, 0x73, 0x6d, 0x01, 0x00, 0x00, 0x00]);" >> %t.js

;; Assemble %t.wat with -g so %t.wasm contains a name custom section that would
;; be stripped if the module were reserialized. Pass %t.wasm as the first input
;; (verifying original binary bytes are preserved) and %t.wat as the second
;; input (verifying WAT is converted to binary before embedding).
;; RUN: echo "(module (func $foo))" > %t.wat
;; RUN: wasm-as %t.wat -g -o %t.wasm

;; RUN: wasm-embed %t.js %t.wasm %t.wat %t.out.js
