4Subject: [PATCH 05/43] [LOCAL]: Fixup debug_loc sections after linker
5 relaxation Adds a new reloctype R_MICROBLAZE_32_NONE, used for passing reloc
6 info from the assembler to the linker when the linker manages to fully
7 resolve a local symbol reference.
8
9This is a workaround for design flaws in the assembler to
10linker interface with regards to linker relaxation.

4Subject: [PATCH 06/43] upstream change to garbage collection sweep causes mb
5 regression
6
7Upstream change for PR13177 now clears the def_regular during gc_sweep of a
8section. (All other archs in binutils/bfd/elf32-*.c received an update
9to a warning about unresolvable relocations - this warning is not present
10in binutils/bfd/elf32-microblaze.c, but this warning check would not
11prevent the error being seen)
12
13The visible issue with this change is when running a c++ application
14in Petalinux which links libstdc++.so for exception handling it segfaults
15on execution.
16
17This does not occur if static linking libstdc++.a, so its during the
18relocations for a shared lib with garbage collection this occurs

4Subject: [PATCH 07/43] Fix bug in TLSTPREL Relocation
5
6Fixed the problem related to the fixup/relocations TLSTPREL.
7When the fixup is applied the addend is not added at the correct offset
8of the instruction. The offset is hard coded considering its big endian
9and it fails for Little endian. This patch allows support for both
10big & little-endian compilers

4Subject: [PATCH 10/43] Add new bit-field instructions
5
6This patches adds new bsefi and bsifi instructions.
7BSEFI- The instruction shall extract a bit field from a
8register and place it right-adjusted in the destination register.
9The other bits in the destination register shall be set to zero
10BSIFI- The instruction shall insert a right-adjusted bit field
11from a register at another position in the destination register.
12The rest of the bits in the destination register shall be unchanged

1079+ if only to serve as a learning tool.
1080+
1081+ The RELOCATE_SECTION function is called by the new ELF backend linker
1082+ to handle the relocations for a section.
1083+
1084+ The relocs are always passed as Rela structures; if the section
1085+ actually uses Rel structures, the r_addend field will always be
1086+ zero.
1087+
1088+ This function is responsible for adjust the section contents as
1089+ necessary, and (if using Rela relocs and generating a
1090+ relocatable output file) adjusting the reloc addend as
1091+ necessary.
1092+
1093+ This function does not have to worry about setting the reloc
1094+ address or the reloc symbol index.
1095+
1096+ LOCAL_SYMS is a pointer to the swapped in local symbols.
1097+
1098+ LOCAL_SECTIONS is an array giving the section in the input file
1099+ corresponding to the st_shndx field of each local symbol.
1100+
1101+ The global hash table entry for the global symbols can be found
1102+ via elf_sym_hashes (input_bfd).
1103+
1104+ When generating relocatable output, this function must handle
1105+ STB_LOCAL/STT_SECTION symbols specially. The output symbol is
1106+ going to be the section symbol corresponding to the output
1107+ section, which means that the addend must be adjusted

4Subject: [PATCH 32/43] Add initial port of linux gdbserver add
5 gdb_proc_service_h to gdbserver microblaze-linux
6
7gdbserver needs to initialise the microblaze registers
8
9other archs use this step to run a *_arch_setup() to carry out all
10architecture specific setup - may need to add in future
11
12 * add linux-ptrace.o to gdbserver configure
13 * Update breakpoint opcode
14 * fix segfault on connecting gdbserver
15 * add microblaze_linux_memory_remove_breakpoint
16 * add set_solib_svr4_fetch_link_map_offsets
17 * add set_gdbarch_fetch_tls_load_module_address
18 * Force reading of r0 as 0, prevent stores

11
12Update to match latest style of components, similar to ppc-linux-nat.c
13
14Update:
15 get_regcache_arch(regcache) to regcache->arch()
16 regcache_raw_supply(regcache, ...) to regcache->raw_supply(...)
17 regcache_raw_collect(regcache, ...) to regcache->raw_collect(...)
