Bug ID: 38797
Summary: lld-link compatibility: reading manifestdpendency from
.drectve
Product: lld
Version: unspecified
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: COFF
Assignee: unassignedb...@nondot.org

cc file using pragma comment to inject /manifestdependency option to the linker
Several of the Visual Studio project templates that produce GUI apps use
#pragma comment(linker, "/manifestdependency:...") directives to add support
for themed controls (WinXP+). lld-link currently errors if it encounters a
/manifestdependency option in the .drectve section.
The project templates place the directive in the PCH file, so multiple .obj
files will include the option.
It's relatively easy enough to workaround, e.g. see
https://github.com/google/UIforETW/pull/123, but obviously lld-link supporting
it would be keen.
>type ManifestDependency.cc
#pragma comment(linker,"/manifestdependency:\"type='win32'
name='Microsoft.Windows.Common-Controls' version='6.0.0.0'
processorArchitecture='*' publicKeyToken='6595b64144ccf1df' language='*'\"")
int main()
{
}
>clang-cl -m32 ManifestDependency.cc
>lld-link ManifestDependency.obj
lld-link.exe: error: /manifestdependency: is not allowed in .drectve
>lld-link --version
LLD 8.0.0
The lld-link binary specifically comes from the installer generated based on
r339039.
