RUN: llvm-mc -filetype=obj -triple=wasm32-unknown-unknown %p/Inputs/start.s -o %t.o
RUN: llvm-mc -filetype=obj -triple=wasm32-unknown-unknown %p/Inputs/ret32.s -o %t.ret32.o
RUN: rm -f %t.a
RUN: llvm-ar rcs %t.a %t.ret32.o

Should not add symbols from the archive by default as they are not required
RUN: wasm-ld --no-gc-sections -o %t.wasm %t.o %t.a
RUN: obj2yaml %t.wasm | FileCheck --check-prefix=NOTADDED %s
NOTADDED: FunctionNames:
NOTADDED-NOT: Name: ret32
NOTADDED: ...

Should add symbols from the archive if --whole-archive is used
RUN: wasm-ld --no-gc-sections -o %t.wasm %t.o --whole-archive %t.a
RUN: obj2yaml %t.wasm | FileCheck --check-prefix=ADDED %s
ADDED: FunctionNames:
ADDED:   Name: ret32
ADDED: ...

--no-whole-archive should restore default behaviour
RUN: wasm-ld --no-gc-sections -o %t.wasm %t.o --whole-archive --no-whole-archive %t.a
RUN: obj2yaml %t.wasm | FileCheck --check-prefix=NOTADDED %s

--whole-archive and --no-whole-archive should affect only archives which follow them
RUN: wasm-ld --no-gc-sections -o %t.wasm %t.o %t.a --whole-archive --no-whole-archive
RUN: obj2yaml %t.wasm | FileCheck --check-prefix=NOTADDED %s
RUN: wasm-ld --no-gc-sections -o %t.wasm %t.o --whole-archive %t.a --no-whole-archive
RUN: obj2yaml %t.wasm | FileCheck --check-prefix=ADDED %s

--whole-archive should also work with thin archives
RUN: rm -f %tthin.a
RUN: llvm-ar --format=gnu rcsT %tthin.a %t.ret32.o
RUN: wasm-ld --no-gc-sections -o %t.wasm %t.o --whole-archive %tthin.a
RUN: obj2yaml %t.wasm | FileCheck --check-prefix=ADDED %s
