Sometimes, symbols are present that point to the end of a section (i.e., one-past the highest valid address). Currently, BOLT either rejects those symbols when they don't point to another existing section, or errs when they do and the other section is not executable. I suppose BOLT would accept the symbol when it points to an executable section. In any case, these symbols should not be considered while discovering functions and should not result in an error. This patch implements that. Note that this patch checks explicitly for symbols whose value equals the end of their section. It might make more sense to verify that the symbol's value is within [section start, section end). However, I'm not sure if this could every happen *and* its value does not equal the end. Another way to implement this is to verify that the BinarySection we find at the symbol's address actually corresponds to the symbol's section. I'm not sure what the best approach is so feedback is welcome. Reviewed By: yota9, rafauler Differential Revision: https://reviews.llvm.org/D146215 |
