## Test disassembling of functions which are spread over multiple sections (ELF

# RUN: ld.lld %t/file.o -o %t/file.out -T %t/file.lds
# RUN: %lldb %t/file.out -o "disassemble --name func1" -o exit | FileCheck %s
# CHECK: (lldb) disassemble --name func1
# CHECK: file.out`func1:
# CHECK-NEXT: file.out[0x0] <+0>: int $0x2a
# CHECK: file.out`func1:
# CHECK-NEXT: file.out[0x1000] <+4096>: int $0x2f

## Linker script placing the parts of the section into different segments
## (typically one of these would be for the "hot" code).
