+Subject: PATCH add Wl,-z,noseparate-code for so
+binutils 2.31 add a separate-code(default)/noseparate-code link option to separate
+.rodata from .text segment. Cause this is a dubious feature that intends to
+reduce the number of ROP gadgets, and this will reduce batch program's
+performance, like unixbench shell program, it will reduce 8%~10%. So
+add 'Wl,-z,noseparate-code' to disable this feature.
