+Subject: [PATCH] riscv: Generate frametable in data section to improve code
+ relocatability (#11042)
+
+Similar to what PowerPC and System-Z have done in commit 24980d3fd9848e281761ef2b8fe383e71261789b
+
+With this commit ocamlopt produces .so shared libraries and PIE relocatable
+executables that contain no relocations in the text segment.
+
+Upstream status: merged in 4.14 and 5.x
