-Subject: [PATCH] Fixup MicroBlaze debug_loc sections after linker relaxation
-
-Fixup debug_loc sections after linker relaxation Adds a new reloctype
-R_MICROBLAZE_32_NONE, used for passing reloc info from the assembler to
-the linker when the linker manages to fully resolve a local symbol
-reference.
-
-This is a workaround for design flaws in the assembler to
-linker interface with regards to linker relaxation.
-
-03/2018
-Rebased for binutils 2.30
