2017-12-12sim: or1k: add or1k target to simStafford Horne
This adds the OpenRISC 32-bit sim target. The OpenRISC sim is a CGEN based sim so the bulk of the code is generated from the .cpu files by CGEN. The engine decode and execute logic in mloop uses scache with pseudo-basic-block extraction and supports both full and fast (switch) modes. The sim does not implement an mmu at the moment. The sim does implement fpu instructions via the common sim-fpu implementation. sim/ChangeLog: 2017-12-12 Stafford Horne <shorne@gmail.com> Peter Gavin <pgavin@gmail.com> * configure.tgt: Add or1k sim. * or1k/README: New file. * or1k/Makefile.in: New file. * or1k/configure.ac: New file. * or1k/mloop.in: New file. * or1k/or1k-sim.h: New file. * or1k/or1k.c: New file. * or1k/sim-if.c: New file. * or1k/sim-main.h: New file. * or1k/traps.c: New file.

FT32B is a new FT32 family member. This patch adds support for the compressed instructions to gdb and sim. gdb/ChangeLog: * ft32-tdep.c (ft32_fetch_instruction): New function.

2017-10-12FT32: support for FT32B processor - part 1James Bowman
FT32B is a new FT32 family member. It has a code compression scheme, which requires the use of linker relaxations. The change is quite large, so submission is in several parts. Part 1 adds a 15-bit instruction field, and CPU-specific functions for the code compression that are used in binutils and GDB. bfd/ChangeLog: 2017-10-12 James Bowman <james.bowman@ftdichip.com> * bfd-in2.h: Regenerate. * libbfd.h: Regenerate. * elf32-ft32.c: Add HOWTO R_FT32_15. * reloc.c: Add BFD_RELOC_FT32_15. gas/ChangeLog: 2017-10-12 James Bowman <james.bowman@ftdichip.com> * config/tc-ft32.c (md_assemble): Replace FT32_FLD_K8 with K15.

This patch fixes the build failure by using disassembler to get disassemble function pointer, and do the disassembly, because print_insn_little_arm is no longer visible outside opcodes/ binutils-gdb/sim/arm/wrapper.c:98:10: error: implicit declaration of function 'print_insn_little_arm' [-Werror=implicit-function-declaration] size = print_insn_little_arm (0, & info); ^ sim/arm: 2017-09-21 Yao Qi <yao.qi@linaro.org> * wrapper.c (print_insn): Use disassembler instead of print_insn_little_arm.

2017-09-04Define an error function in the PPC simulator library.John Baldwin
Previously this used the error function from GDB directly when linked against GDB instead of the error method in the host callbacks structure. This was exposed via a link error when GDB was converted to C++. The error function invokes the error callback similar to sim_io_error. Note that there are also error functions in sim/ppc/main.c and sim/ppc/misc.c. The ppc libsim.a expects each consumer to provide several symbols used by the library including "error". sim-calls.c provides these symbols when the library is linked into gdb. The dgen, igen, tmp-filter, tmp-ld-decode, tmp-ld-cache, and tmp-ld-insn programs use the functions from misc.c. psim uses the functions from main.c. sim/ppc/ChangeLog: PR sim/20863 * sim_calls.c (error): New function.

2017-05-24Refactor disassembler selectionYao Qi
Nowadays, opcodes/disassemble.c:disassembler selects the proper disassembler according to ABFD only. However, it actually selects disassemblers according to arch, mach, endianess, and abfd. This patch adds them to the parameters of disassembler, so that its caller can still select disassemblers in case that abfd is NULL (a typical case in GDB). There isn't any functionality change. binutils: 2017-05-24 Yao Qi <yao.qi@linaro.org> * objdump.c (disassemble_data): Caller update. include: 2017-05-24 Yao Qi <yao.qi@linaro.org> * dis-asm.h (disassembler): Update declaration. opcodes: 2017-05-24 Yao Qi <yao.qi@linaro.org> * disassemble.c (disassembler): Add arguments a, big and mach.

The common sim tracing code already handles loading and tracking of symbols from the target program so that it can show symbol info in trace/disassembly calls.
