.clangd

# clangd only; the real build flags live in the Makefile and compiler.mk. The
# point here is to make the editor see the same world the cross-compiler
# does: AmigaOS headers, no host glibc, 32-bit pointers, and the
# per-directory flags the Makefile's pattern rules add.
#
# Paths are absolute because clangd expands neither ~ nor $HOME, and because a
# relative -I would resolve against each file's own directory. Adjust them if
# the toolchain or this checkout lives elsewhere.

    # supply.

    # must be told to leave it alone.
