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

5 | |||
6 | Fixed the problem related to the fixup/relocations TLSTPREL. | ||
7 | When the fixup is applied the addend is not added at the correct offset | ||
8 | of the instruction. The offset is hard coded considering its big endian | ||
9 | and it fails for Little endian. This patch allows support for both | ||
10 | big & little-endian compilers | ||

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

6 | |||
7 | gdbserver needs to initialise the microblaze registers | ||
8 | |||
9 | other archs use this step to run a *_arch_setup() to carry out all | ||
10 | architecture 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 | ||
