2 * This file is used to test dsymutil support for call site entries
3 * (DW_TAG_call_site / DW_AT_call_return_pc).
4 *
5 * Instructions for regenerating binaries (on Darwin/x86_64):
6 *
7 * 1. Copy the source to a top-level directory to work around having absolute
8 * paths in the symtab's OSO entries.
9 *
10 * mkdir -p /Inputs/ && cp call-site-entry.c /Inputs && cd /Inputs
11 *
12 * 2. Compile with call site info enabled.
13 *
14 * clang -g -O1 -Xclang -disable-llvm-passes call-site-entry.c -c -o call-site-entry.macho.x86_64.o
15 * clang call-site-entry.macho.x86_64.o -o call-site-entry.macho.x86_64
16 *
17 * 3. Copy the binaries back into the repo's Inputs directory. You'll need
18 * -oso-prepend-path=%p to link.
