+ * ld-elf/comm-data.exp: Use check_shared_lib_support rather than
+ explicit patterns for test target qualification. Define extra
+ tool flags for *-*-hpux* and tic6x-*-* targets. Link with a
+ linker script. Use alternative patterns for targets that do not
+ eliminate copy relocs, currently mn10300-*-* and vax-*-*.
+ * ld-elf/comm-data2.s: Handle HPUX's `.comm' syntax.
+ * ld-elf/comm-data2.ld: New test linker script.
+ * ld-elf/comm-data2.xd: Match section's VMA too. Ignore ASCII
+ data dump.
+ * ld-elf/comm-data2r.rd: New test pattern.
