REQUIRES: x86
RUN: split-file %s %t.dir && cd %t.dir

Link to an import library containing EXPORTAS and verify that we use proper name for the import.

RUN: llvm-mc -filetype=obj -triple=x86_64-windows test.s -o test.obj
RUN: llvm-lib -machine:amd64 -out:test.lib -def:test.def
RUN: lld-link -out:out1.dll -dll -noentry test.obj test.lib
RUN: llvm-readobj --coff-imports out1.dll | FileCheck --check-prefix=IMPORT %s
IMPORT: Symbol: expfunc

Pass -export argument with EXPORTAS.

RUN: llvm-mc -filetype=obj -triple=x86_64-windows func.s -o func.obj
RUN: lld-link -out:out2.dll -dll -noentry func.obj -export:func,EXPORTAS,expfunc

IMPLIB:      Name type: export as
IMPLIB-NEXT: Export name: expfunc
IMPLIB-NEXT: Symbol: __imp_func

Use .drectve section with EXPORTAS.

RUN: llvm-mc -filetype=obj -triple=x86_64-windows drectve.s -o drectve.obj
RUN: lld-link -out:out3.dll -dll -noentry func.obj drectve.obj
RUN: llvm-readobj --coff-exports out3.dll | FileCheck --check-prefix=EXPORT %s
RUN: llvm-readobj out3.lib | FileCheck --check-prefix=IMPLIB %s

Use a .def file with EXPORTAS.

RUN: lld-link -out:out4.dll -dll -noentry func.obj -def:test.def
RUN: llvm-readobj --coff-exports out4.dll | FileCheck --check-prefix=EXPORT %s
RUN: llvm-readobj out4.lib | FileCheck --check-prefix=IMPLIB %s

Use a .def file with EXPORTAS in a forwarding export.

RUN: lld-link -out:out5.dll -dll -noentry func.obj -def:test2.def
RUN: llvm-readobj --coff-exports out5.dll | FileCheck --check-prefix=FORWARD-EXPORT %s
FORWARD-EXPORT:      Export {

Pass -export argument with EXPORTAS in a forwarding export.

RUN: lld-link -out:out6.dll -dll -noentry func.obj -export:func=otherdll.otherfunc,EXPORTAS,expfunc
RUN: llvm-readobj --coff-exports out6.dll | FileCheck --check-prefix=FORWARD-EXPORT %s
RUN: llvm-readobj out6.lib | FileCheck --check-prefix=FORWARD-IMPLIB %s

Pass -export argument with EXPORTAS in a data export.

RUN: lld-link -out:out7.dll -dll -noentry func.obj -export:func,DATA,@5,EXPORTAS,expfunc
RUN: llvm-readobj --coff-exports out7.dll | FileCheck --check-prefix=ORD %s
ORD:      Ordinal: 5
ORD-NEXT: Name: expfunc

ORD-IMPLIB:      Type: data
ORD-IMPLIB-NEXT: Name type: export as
ORD-IMPLIB-NEXT: Export name: expfunc
ORD-IMPLIB-NEXT: Symbol: __imp_func

Check invalid EXPORTAS syntax.

RUN: not lld-link -out:err1.dll -dll -noentry func.obj -export:func,EXPORTAS, 2>&1 | \
