# REQUIRES: x86 ## Test creating a DLL and linking against the DLL without using an import ## library. ## Test on i386 with stdcall/fastcall/vectorcall decorated symbols. ## Check that we normally warn about these fixups.

If we -stdcall-fixup (--enable-stdcall-fixup on the MinGW ## linker level) is passed, we don't warn about it at all. # RUN: split-file %s %t.dir # RUN: llvm-mc -filetype=obj -triple=i386-windows-gnu %t.dir/lib.s -o %t.lib.o # RUN: lld-link -safeseh:no -noentry -dll -def:%t.dir/lib.def %t.lib.o -out:%t.lib.dll -implib:%t.implib.lib # RUN: llvm-mc -filetype=obj -triple=i386-windows-gnu %t.dir/main.s -o %t.main.o # RUN: lld-link -lldmingw %t.main.o -out:%t.main.exe %t.lib.dll -opt:noref 2>&1 | FileCheck --check-prefix=LOG %s # RUN: llvm-readobj --coff-imports %t.main.exe | FileCheck %s # RUN: not lld-link -lldmingw %t.main.o -out:%t.main.exe %t.lib.dll -opt:noref -stdcall-fixup:no 2>&1 | FileCheck --check-prefix=ERROR %s # RUN: lld-link -lldmingw %t.main.o -out:%t.main.exe %t.lib.dll -opt:noref -stdcall-fixup 2>&1 | count 0 #--- lib.s .text .globl _stdcall@8 .globl @fastcall@8 .globl vectorcall@@8 .globl __underscored _stdcall@8: movl 8(%esp), %eax addl 4(%esp), %eax retl $8 @fastcall@8: movl 8(%esp), %eax addl 4(%esp), %eax retl $8 vectorcall@@8: movl 8(%esp), %eax addl 4(%esp), %eax retl $8 __underscored: ret #--- lib.def EXPORTS stdcall fastcall vectorcall _underscored #--- main.s .text .global _mainCRTStartup _mainCRTStartup: pushl $2 pushl $1 calll _stdcall@8 movl $1, %ecx movl $2, %edx calll @fastcall@8 movl $1, %ecx movl $2, %edx calll vectorcall@@8 pushl $2 pushl $1 calll __underscored addl $8, %esp xorl %eax, %eax popl %ebp retl # CHECK: Import { # CHECK-NEXT: Name: link-dll-stdcall.s.tmp.lib.dll # CHECK-NEXT: ImportLookupTableRVA: # CHECK-NEXT: ImportAddressTableRVA # CHECK-NEXT: Symbol: _underscored # CHECK-NEXT: Symbol: fastcall # CHECK-NEXT: Symbol: stdcall # CHECK-NEXT: Symbol: vectorcall # CHECK-NEXT: } # LOG-DAG: Resolving vectorcall@@8 by linking to _vectorcall # LOG-DAG: Resolving @fastcall@8 by linking to _fastcall # LOG-DAG: Resolving _stdcall@8 by linking to _stdcall # ERROR-DAG: undefined symbol: _stdcall@8 # ERROR-DAG: undefined symbol: @fastcall@8 # ERROR-DAG: undefined symbol: vectorcall@@8
