The only non-renamed symbols are linkset delimiters and 117# the GOT, which are more a property of the compiler than the kernel. 118# 119# Some toolchains generate unresolved symbols which are supposed to be 120# satisfied by the toolchain itself when the program is linked. 121# Unfortunately, we do not know which of the symbols are generated by 122# the toolchain. Worse, they vary from platform to platform and 123# toolchain to toolchain.
