26 | # The goal of this program is to verify if --icf=safe works with | |
27 | # -pie as expected. File icf_safe_test.cc is in this test. This | |
28 | # program checks if only ctors and dtors are folded, except for | |
29 | # the architectures which use relocation types and instruction | |
30 | # opcodes to detect if function pointers are taken. | |
