/usr/bin/clang-linker-wrapper

C language family frontend for LLVM 15

From clang-15 15.0.7-r32 (os), captured 2026-11-05 by running clang-linker-wrapper --help (exit 0). permalink

OVERVIEW:
A wrapper utility over the host linker. It scans the input files
for sections that require additional processing prior to linking.
The will then transparently pass all arguments and input to the
specified host linker to create the final binary.
