+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 07/40] upstream change to garbage collection sweep causes mb
+ regression
+
+Upstream change for PR13177 now clears the def_regular during gc_sweep of a
+section. (All other archs in binutils/bfd/elf32-*.c received an update
+to a warning about unresolvable relocations - this warning is not present
+in binutils/bfd/elf32-microblaze.c, but this warning check would not
+prevent the error being seen)
+
+The visible issue with this change is when running a c++ application
+in Petalinux which links libstdc++.so for exception handling it segfaults
+on execution.
+
+This does not occur if static linking libstdc++.a, so its during the
+relocations for a shared lib with garbage collection this occurs

+Subject: [PATCH 10/40] Add new bit-field instructions
+
+This patches adds new bsefi and bsifi instructions.
+BSEFI- The instruction shall extract a bit field from a
+register and place it right-adjusted in the destination register.
+The other bits in the destination register shall be set to zero
+BSIFI- The instruction shall insert a right-adjusted bit field
+from a register at another position in the destination register.
+The rest of the bits in the destination register shall be unchanged

++   There is some attempt to make this function usable for many architectures,
++   both USE_REL and USE_RELA ['twould be nice if such a critter existed],
++   if only to serve as a learning tool.
++
++   The RELOCATE_SECTION function is called by the new ELF backend linker
++   to handle the relocations for a section.
++
++   The relocs are always passed as Rela structures; if the section
++   actually uses Rel structures, the r_addend field will always be
++   zero.
++
++   This function is responsible for adjust the section contents as
++   necessary, and (if using Rela relocs and generating a
++   relocatable output file) adjusting the reloc addend as
++   necessary.
++
++   This function does not have to worry about setting the reloc
++   address or the reloc symbol index.
++
++   LOCAL_SYMS is a pointer to the swapped in local symbols.
++
++   LOCAL_SECTIONS is an array giving the section in the input file
++   corresponding to the st_shndx field of each local symbol.
++
++   The global hash table entry for the global symbols can be found
++   via elf_sym_hashes (input_bfd).
++
++   When generating relocatable output, this function must handle
++   STB_LOCAL/STT_SECTION symbols specially.  The output symbol is
++   going to be the section symbol corresponding to the output
++   section, which means that the addend must be adjusted
++   accordingly.  */

+
+The base system expect md_pseudo_table to be constant, Changing the
+definition will break other architectures when compiled with a
+unified source code.
+
+Patch reverts the change away from const, and implements a newer
+dynamic handler that passes the correct argument value based on word
+size.

+Subject: [PATCH 34/40] Add initial port of linux gdbserver add
+ gdb_proc_service_h to gdbserver microblaze-linux
+
+gdbserver needs to initialise the microblaze registers
+
+other archs use this step to run a *_arch_setup() to carry out all
+architecture specific setup - may need to add in future
+
+ * add linux-ptrace.o to gdbserver configure
+ * Update breakpoint opcode
+ * fix segfault on connecting gdbserver
+ * add microblaze_linux_memory_remove_breakpoint
+ * add set_solib_svr4_fetch_link_map_offsets
+ * add set_gdbarch_fetch_tls_load_module_address
+ * Force reading of r0 as 0, prevent stores

+ msmall-divides flag
+
+Compiler is crashing when we use msmall-divides and mxl-barrel-shift flag.
+This is because when use above flags microblaze_expand_divide function will be
+called for division operation. In microblaze_expand_divide function we are
+using sub_reg but MicroBlaze doesn't have subreg register due to this compiler
+was crashing. Changed the logic to avoid sub_reg call

+Subject: [PATCH 16/58] [Patch, microblaze]: Add INIT_PRIORITY support
+
+Added TARGET_ASM_CONSTRUCTOR and TARGET_ASM_DESTRUCTOR macros.
+
+These macros allows users to control the order of initialization
+of objects defined at namespace scope with the init_priority
+attribute by specifying a relative priority, a constant integral
+expression currently bounded between 101 and 65535 inclusive.
+
+Lower numbers indicate a higher priority.
+
+Changelog
+
+2013-11-26  Nagaraju Mekala <nagaraju.mekala@xilinx.com>

+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 22/58] [PATCH] microblaze.md: Improve 'adddi3' and 'subdi3'
+ insn definitions
+
+Change adddi3 to handle DI immediates as the second operand, this
+requires modification to the output template however reduces the need to
+specify seperate templates for 16-bit positive/negative immediate
+operands. The use of 32-bit immediates for the addi and addic
+instructions is handled by the assembler, which will emit the imm
+instructions when required. This conveniently handles the optimizable
+cases where the immediate constant value does not need the higher half
+words of the operands upper/lower words.
+
+Change the constraints of the subdi3 instruction definition such that it
+does not match the second operand as an immediate value. This is because
+there is no definition to handle this case nor is it possible to
+implement purely with instructions as microblaze does not provide an
+instruction to perform a forward arithmetic subtraction (it only
+provides reverse 'rD = IMM - rA').

+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.
+

+This patch will change the calculation of high word in a long long 64-bit.
+Earlier to this patch the high word of long long word (0xF0000000ULL) is
+coming to be 0xFFFFFFFF and low word is 0xF0000000. Instead the high word
+should be 0x00000000 and the low word should be 0xF0000000. This patch
+removes the condition of checking high word = 0 & low word < 0.
+This check is not required for the correctness of calculating 32-bit high

+Subject: [PATCH 29/58] [Patch, microblaze]: Add new bit-field instructions
+
+This patches adds new bsefi and bsifi instructions.
+BSEFI- The instruction shall extract a bit field from a
+register and place it right-adjusted in the destination register.
+The other bits in the destination register shall be set to zero
+BSIFI- The instruction shall insert a right-adjusted bit field
+from a register at another position in the destination register.
+The rest of the bits in the destination register shall be unchanged

+Subject: [PATCH 53/58] [Patch, microblaze]: MB-64 removal of barrel-shift
+ instructions from default
+
+By default MB-64 is generatting barrel-shift instructions. It has been
+removed from default. Barrel-shift instructions will be generated only if
+barrel-shifter is enabled. Similarly to double instructions as well.

+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 07/40] upstream change to garbage collection sweep causes mb
+ regression
+
+Upstream change for PR13177 now clears the def_regular during gc_sweep of a
+section. (All other archs in binutils/bfd/elf32-*.c received an update
+to a warning about unresolvable relocations - this warning is not present
+in binutils/bfd/elf32-microblaze.c, but this warning check would not
+prevent the error being seen)
+
+The visible issue with this change is when running a c++ application
+in Petalinux which links libstdc++.so for exception handling it segfaults
+on execution.
+
+This does not occur if static linking libstdc++.a, so its during the
+relocations for a shared lib with garbage collection this occurs

+Subject: [PATCH 08/40] Fix bug in TLSTPREL Relocation
+
+Fixed the problem related to the fixup/relocations TLSTPREL.
+When the fixup is applied the addend is not added at the correct offset
+of the instruction. The offset is hard coded considering its big endian
+and it fails for Little endian. This patch allows support for both
+big & little-endian compilers

+Subject: [PATCH 10/40] Add new bit-field instructions
+
+This patches adds new bsefi and bsifi instructions.
+BSEFI- The instruction shall extract a bit field from a
+register and place it right-adjusted in the destination register.
+The other bits in the destination register shall be set to zero
+BSIFI- The instruction shall insert a right-adjusted bit field
+from a register at another position in the destination register.
+The rest of the bits in the destination register shall be unchanged

++   There is some attempt to make this function usable for many architectures,
++   both USE_REL and USE_RELA ['twould be nice if such a critter existed],
++   if only to serve as a learning tool.
++
++   The RELOCATE_SECTION function is called by the new ELF backend linker
++   to handle the relocations for a section.
++
++   The relocs are always passed as Rela structures; if the section
++   actually uses Rel structures, the r_addend field will always be
++   zero.
++
++   This function is responsible for adjust the section contents as
++   necessary, and (if using Rela relocs and generating a
++   relocatable output file) adjusting the reloc addend as
++   necessary.
++
++   This function does not have to worry about setting the reloc
++   address or the reloc symbol index.
++
++   LOCAL_SYMS is a pointer to the swapped in local symbols.
++
++   LOCAL_SECTIONS is an array giving the section in the input file
++   corresponding to the st_shndx field of each local symbol.
++
++   The global hash table entry for the global symbols can be found
++   via elf_sym_hashes (input_bfd).
++
++   When generating relocatable output, this function must handle
++   STB_LOCAL/STT_SECTION symbols specially.  The output symbol is
++   going to be the section symbol corresponding to the output
++   section, which means that the addend must be adjusted
++   accordingly.  */

+Subject: [PATCH 34/40] Add initial port of linux gdbserver add
+ gdb_proc_service_h to gdbserver microblaze-linux
+
+gdbserver needs to initialise the microblaze registers
+
+other archs use this step to run a *_arch_setup() to carry out all
+architecture specific setup - may need to add in future
+
+ * add linux-ptrace.o to gdbserver configure
+ * Update breakpoint opcode
+ * fix segfault on connecting gdbserver
+ * add microblaze_linux_memory_remove_breakpoint
+ * add set_solib_svr4_fetch_link_map_offsets
+ * add set_gdbarch_fetch_tls_load_module_address
+ * Force reading of r0 as 0, prevent stores
