... to customize the tombstone value we use for an absolute relocation referencing a discarded symbol. This can be used as a workaround when some debug processing tool has trouble with current -1 tombstone value (https://bugs.chromium.org/p/chromium/issues/detail?id=1102223#c11 ) For example, to get the current built-in rules (not considering the .debug_line special case for ICF): ``` -z dead-reloc-in-nonalloc='.debug_*=0xffffffffffffffff' -z dead-reloc-in-nonalloc=.debug_loc=0xfffffffffffffffe -z dead-reloc-in-nonalloc=.debug_ranges=0xfffffffffffffffe ``` To get GNU ld (as of binutils 2.35)'s behavior: ``` -z dead-reloc-in-nonalloc='*=0' -z dead-reloc-in-nonalloc=.debug_ranges=1 ``` This option has other use cases. For example, if we want to check whether a non-SHF_ALLOC section has dead relocations. With this patch, we can run a regular LLD and run another with a special -z dead-reloc-in-nonalloc=, then compare their output.
