Fix SPARC64 handling of R_SPARC_H34 (bug 24231).
Building glibc with -Wextra shows a -Wimplicit-fallthrough warning for SPARC64 that appears to be a real bug in glibc. The dynamic linker handling of R_SPARC_H34 falls through to that of R_SPARC_H44, which in the case of this code is nonsensical (it means the value computed for R_SPARC_H34 gets overwritten by one computed with the different logic for R_SPARC_H44). Thus, this patch adds the missing break there. Note: I do not have a testcase to demonstrate this bug. Tested with build-many-glibcs.py. [BZ #24231] * sysdeps/sparc/sparc64/dl-machine.h (elf_machine_rela): Add break after R_SPARC_H34 case.
