# Verify that we split C string literals on null-terminators, rather than on
|
|
# symbol boundaries. We expect four dead-stripped symbols: l_str.0, l_str.2,
|
|
# L_str.3, l_str.4, and the auto-generated symbol for the start of the "defghi"
|
|
# string. We also verify that there are only two dead-stripped blocks, since
|
|
# l_str.3 should not have split the block started at "def"... (since this is a
|
|
# C string section we should be splitting on null characters instead of
|
|
# symbols).
