+ * elf/elf.h (R_PPC64_TLSGD, R_PPC64_TLSLD, R_PPC64_TOCSAVE): Define.
+ (R_PPC64_ADDR16_HIGH, R_PPC64_ADDR16_HIGHA): Likewise.
+ (R_PPC64_TPREL16_HIGH, R_PPC64_TPREL16_HIGHA): Likewise.
+ (R_PPC64_DTPREL16_HIGH, R_PPC64_DTPREL16_HIGHA): Likewise.
+
+ * sysdeps/powerpc/powerpc64/dl-machine.h (elf_machine_rela): Add
+ overflow checking for R_PPC64_ADDR16_HI, R_PPC64_ADDR16_HA,
+ R_PPC64_TPREL16_HI, and R_PPC64_TPREL16_HA.
+ Support new R_PPC64_ADDR16_HIGH, R_PPC64_ADDR16_HIGHA,
+ R_PPC64_TPREL16_HIGH, and R_PPC64_TPREL16_HIGHA relocations.
+ Fix overflow checking for R_PPC64_ADDR30 and R_PPC64_ADDR32.
