# Check for an issue in GDB where buildsym_compunit::record_line was
|
|
# removing duplicate line table entries, but skip_prologue_using_sal
|
|
# depends on these duplicates to spot the end of the prologue.
|
|
#
|
|
# When the de-duplication was added this regression was not spotted as
|
|
# it requires a particular combination of a (very) small function
|
|
# being inlined into an also very small outer function.

|
#
|
|
# See also gdb.dwarf/dw2-inline-small-func.exp for a version of this
|
|
# test that makes use of the Dejagnu DWARF compiler.
|
|
#
|
|
# This test simply compiles with optimization and checks that GDB can
|
|
# do something suitable with the compiled binary. Problems with this
|
|
# test are most likely to occur when GDB asks the target specific code
|
|
# to skip the prologue (gdbarch_skip_prologue). Some targets make use
|
|
# of skip_prologue_using_sal, which should be fine, however, some
|
|
# targets make a poor attempt to duplicate parts of
|
|
# skip_prologue_using_sal, these targets could easily fail this test.
|
|
# This is not (necessarily) a problem with this test, but could
|
|
# indicate a weakness with the target in question.
