+Subject: [PATCH 04/52] [LOCAL]: Fix relaxation of assembler resolved
+ references,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.

-Subject: [PATCH 06/40] microblaze: 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.

+Subject: [PATCH 48/52] bfd/elf*-microblaze.c: Remove obsolete entries
+
+Replace microblaze_elf_merge_private_bfd_data with a direct call to
+_bfd_generic_verify_endian_match, this simplifies the implementation.
+
+Remove microblaze_elf_gc_sweep_hook, removed in 2017.

-Subject: [PATCH 20/58] [Patch,microblaze]: Inline Expansion of fsqrt builtin.
-
-The changes are made in the patch for the inline expansion of
-the fsqrt builtin with fqrt instruction. The sqrt math function
-takes double as argument and return double as argument. The
-pattern is selected while expanding the unary op through
-expand_unop which passes DFmode and the DFmode pattern was
-not there returning zero. Thus the sqrt math function is not
-inlined and expanded. The pattern with DFmode argument is added.
-Also the source and destination argument is not same the DF
-through two different consecutive registers with lower 32 bit
-is the argument passed to sqrt and the higher 32 bit is zero.
-If the source and destinations are different the DFmode 64 bits
-registers is not set properly giving the problem in runtime. Such
-changes are taken care in the implementation of the pattern for
-DFmode for inline expansion of the sqrt.

-Subject: [PATCH 25/58] [Patch,rtl Optimization]: Better register pressure
- estimate for loop invariant code motion
-
-Calculate the loop liveness used for regs for calculating the register pressure
-in the cost estimation.  Loop liveness is based on the following properties.
-We only need to find the set of objects that are live at the birth or the header
-of the loop. We don't need to calculate the live through the loop by considering
-live in and live out of all the basic blocks of the loop. This is based on the
-point that the set of objects that are live-in at the birth or header of the loop
-will be live-in at every node in the loop.
-
-If a v live is out at the header of the loop then the variable is live-in at every node
-in the loop. To prove this, consider a loop L with header h such that the variable v
-defined at d is live-in at h. Since v is live at h, d is not part of L. This follows i
-from the dominance property, i.e. h is strictly dominated by d. Furthermore, there
-exists a path from h to a use of v which does not go through d. For every node p in
-the loop, since the loop is strongly connected and node is a component of the CFG,
-there exists a path, consisting only of nodes of L from p to h. Concatenating these
-two paths proves that v is live-in and live-out of p.
-
-Calculate the live-out and live-in for the exit edge of the loop. This patch considers
-liveness for not only the loop latch but also the liveness outside the loops.
-
-ChangeLog:
-2016-01-22  Ajit Agarwal  <ajitkum@xilinx.com>
-
-	* loop-invariant.c
-	(find_invariants_to_move): Add the logic of regs_used based
-	on liveness.
-	* cfgloopanal.c
-	(estimate_reg_pressure_cost): Update the heuristics in presence
-	of call_p.

-Subject: [PATCH 26/58] [Patch, microblaze]: Correct the const high double
- immediate value
-
-With this patch the loading of the DI mode immediate values will be
-using REAL_VALUE_FROM_CONST_DOUBLE and REAL_VALUE_TO_TARGET_DOUBLE
-functions, as CONST_DOUBLE_HIGH was returning the sign extension value
-even of the unsigned long long constants also

- *microblaze.c (print_operand): Use REAL_VALUE_FROM_CONST_DOUBLE &
-        REAL_VALUE_TO_TARGET_DOUBLE
- *long.c (new): Added new testcase

+Subject: [PATCH 04/52] [LOCAL]: Fix relaxation of assembler resolved
+ references,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.

-Subject: [PATCH 06/40] microblaze: 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.

+ldemul.o:(.data.rel+0x828): undefined reference to `ld_elf64microblaze_emulation'
+
+The error appears to be that the elf64 files were referencing the elf32 emulation.

+Subject: [PATCH 48/52] bfd/elf*-microblaze.c: Remove obsolete entries
+
+Replace microblaze_elf_merge_private_bfd_data with a direct call to
+_bfd_generic_verify_endian_match, this simplifies the implementation.
+
+Remove microblaze_elf_gc_sweep_hook, removed in 2017.
