Bug ID: 48096
Summary: Non-constructor function pointers in .ctors are
dropped
Product: lld
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: ELF
Assignee: unassignedb...@nondot.org
Reporter: d...@google.com
CC: llvm-bugs@lists.llvm.org, mask...@google.com,

LLD seems to drop function pointers in the `.ctors` section that are not C++
constructors.
Example:

There's a lot going on here with priority ordering, but the upshot that BFD LD
preserves function pointers (which are not C++ constructors) explicitly placed
into `.ctors` or `.ctors.*` with both GCC and Clang, but Clang+LLD drops them.
(The same happens with C, where there are no actual C++ constructors:
