test/Shell/SymbolFile/DWARF/wasm-function-display-name.yaml

# A function whose DWARF DW_AT_linkage_name is present but is NOT a mangled
# name -- it differs from DW_AT_name. This happens on WebAssembly, where
# wasi-libc renames `main` to its `__main_argc_argv` argv-passing wrapper:
# the DWARF keeps DW_AT_name "main" but records DW_AT_linkage_name
# "__main_argc_argv". Here the same shape is produced with an asm() rename.
#
# LLDB must display the source name (DW_AT_name, "impl") rather than the raw,
# un-demanglable linkage name, while still keeping the linkage name as the
# symbol so a breakpoint set by either name resolves.

# RUN: yaml2obj %s -o %t
# RUN: %lldb %t \
# RUN:   -o "image lookup -v -n impl" \
# RUN:   -o "breakpoint set -n impl" \
# RUN:   -o exit 2>&1 | FileCheck %s

# The function is displayed by its source name, with the linkage name kept as
# the symbol; a breakpoint set by the source name resolves and displays it too.
# CHECK: Function: {{.*}}name = "impl", mangled = "renamed_export"
# CHECK: Breakpoint 1: where = {{.*}}`impl
