Modified Files: src/lib/csu/common: crtbegin.c Log Message: PR toolchain/51121: __CTOR_LIST__ and __CTOR_LIST_END__ are logically the same object, but due to the start marker, the former has to be declared as array of fixed size. Newer GCC versions take the liberty of exploiting the UB of accessing global objects past the end to unconditionally load zero values in that case. Two fixes are possible: (1) Pruning via inline assembler as done by GCC's own CRT copy. (2) Pruning via weak references as done for linker sets. Since the second part is known and required to work anyway, prefer this approach. In theory, the labels could be replaced completely, except that GNU as doesn't provide start/end symbols for sections containing dots.
