Re: [PATCH v3] xtensa: add R_XTENSA_PDIFF_ULEB128 for DWARF uleb128 diffs
Alexey Lapshin is gently pinging for a review of a patch that adds the R_XTENSA_PDIFF_ULEB128 relocation type, intended for DWARF uleb128 diffs on Xtensa architectures. Without immediate review, they request that reloc type 63 be reserved for this purpose.
