| // The goal with this test is: |
| // 1. Have main() followed by foo() |
| // 2. Have the no-return call to abort() in main be the last instruction |
| // 3. Have the next instruction be the start of foo() |
| // 4. The debug info for argv uses a location list. |
| // clang at -O1 on x86_64 or arm64 has debuginfo like |
| // DW_AT_location (0x00000049: |
| // [0x0000000100003f15, 0x0000000100003f25): DW_OP_reg4 RSI |
| // [0x0000000100003f25, 0x0000000100003f5b): DW_OP_reg15 R15) |
