# Check that ptrauth edges are _not_ lowered for noalloc sections.
#
# Ptrauth edges are lowered to signing function instructions, so any ptrauth
# edge in a noalloc section will introduce signing instructions that operate
# illegally on linker working memory, rather than executor memory (this will
# usually lead to a crash, but may silently corrupt memory in in-process JITs).
#
# By ignoring these edges during ptrauth lowering we prevent illegal signing
# instructions from being generated, and the ptrauth edges error out in
# applyFixup instead.
#

# CHECK: llvm-jitlink error: {{.*}} unsupported edge kind Pointer64Authenticated
