// 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)
