How this entity was disambiguated
This entity first appeared as the object of triple T2716453 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: libc++abi Context triple: [LLVM, hasComponent, libc++abi]
-
A.
Microsoft C++ ABI
The Microsoft C++ ABI is the application binary interface that defines how C++ code is represented, called, and linked on Microsoft platforms, ensuring binary compatibility between compilers and libraries in the Windows ecosystem.
-
B.
Itanium C++ ABI
The Itanium C++ ABI is a widely adopted application binary interface specification that standardizes C++ object layout, name mangling, and calling conventions across many non-Windows platforms and compilers.
-
C.
GNU C Library
The GNU C Library (glibc) is the GNU Project’s core implementation of the standard C library, providing fundamental system call wrappers and APIs used by most GNU/Linux and Unix-like systems.
-
D.
o32 ABI
o32 ABI is a widely used 32-bit application binary interface for MIPS architectures that defines calling conventions, data types, and binary formats for compiled programs.
-
E.
compiler-rt
compiler-rt is the LLVM runtime library project that provides low-level compiler support routines such as builtins, sanitizers, and profiling helpers used by code generated with LLVM-based toolchains.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: libc++abi Description of subject: libc++abi is the LLVM project's C++ ABI support library that provides low-level runtime features such as exception handling and type information for the libc++ standard library.
