+Subject: [PATCH] Add relocation type R_X86_64_REX_GOTPCRELX
+
+Summary:
+Adding support for the `R_X86_64_REX_GOTPCRELX` relocation type.
+This relocation is treated by the linker the same as the `R_X86_64_GOTPCRELX` type
+`G + GOT + A - P` to generate relative offsets to the GOT.
+The `REX` prefix has no influence in this stage.
+
+This is based on https://github.com/hjl-tools/x86-psABI/wiki/x86-64-psABI-r252.pdf
