# Test that we report pcpair ranges from DIEs that have:
# 0x00000010:   DW_TAG_subprogram
#                 DW_AT_low_pc	(0x0000000000001000)
#                 DW_AT_high_pc	(0x0000000000001010)
#
# This is the most common way of getting data for the compileunits
# data source.

# RUN: %yaml2obj %s --docnum=1 -o %t.obj
# RUN: %yaml2obj %s --docnum=2 -o %t.dwo
# RUN: %bloaty %t.obj --debug-file %t.dwo -d compileunits --raw-map --domain=vm | %FileCheck %s
