# Tests RISC-V relocations. We provide a .debug_info section with multiple
# DW_AT_high_pc entries (that's one of the attributes for which relocations are
# resolved by llvm-dwarfdump) and we add a relocation for each of them.
#
# RUN: yaml2obj %s | llvm-dwarfdump - | FileCheck %s
# To add more tests you need to modify the Content of the .debug_abbrev and
# .debug_info sections. To do that create a test.s which matches the assembly
# code below, run the command that follows and copy over the "Content" value of
# the respective sections:
#
# ```
# $ cat test.s
# .section .debug_abbrev,"",@progbits
# .byte 1 # Abbreviation Code
# .byte 0x11 # DW_TAG_compile_unit
# .byte 0 # DW_CHILDREN_no
#
# # Add a DW_AT_high_pc for each relocation we test.
