Bug ID: 20068
Summary: LinkModules with PreserveSource doesn't retain type
names
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Linker
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
Created attachment 12674
--> http://llvm.org/bugs/attachment.cgi?id=12674&action=edit
Code to reproduce the bug.
In the attached example, calling:
Linker::LinkModules(dest, src, Linker::PreserveSource, 0);
removes the type names from the src module, making them anonymous and
preventing src from being used to link to other modules.
src module before linking:
%mytype = type { i8 }
define %mytype @baz(%mytype %bar) {
ret %mytype %bar
}
src module after linking:
%0 = type { i8 }
define %0 @baz(%0 %bar) {
ret %0 %bar
}
$ llvm-config --version
