# Rename library symbols before use. If a symbol does not already belong
|
|
# to a rump namespace ("rump" or "RUMP"), prefix it with "rumpns". This
|
|
# avoids accidentally linking any kernel symbol against host platform
|
|
# libraries. The only non-renamed symbols are linkset delimiters and
|
|
# the GOT, which are more a property of the compiler than the kernel.
|
|
#
|
|
# Some toolchains generate unresolved symbols which are supposed to be
|
|
# satisfied by the toolchain itself when the program is linked.
|
|
# Unfortunately, we do not know which of the symbols are generated by
|
|
# the toolchain. Worse, they vary from platform to platform and
|
|
# toolchain to toolchain. The good news, however, is that this will
|
|
# be detected by a compile-time failure, so we can fairly easily manage
|
|
# a quirktable here.
