2017-06-25 Graham Markall <graham.markall@embecosm.com>
* targets/picorv32/Picorv32.cpp: (RUN_SAMPLE_PERIOD) Add.
(resume) When step is CONTINUE, step for RUN_SAMPLE_PERIOD
instructions; if timeout expired, return TIMEOUT.
Otherwise, repeat. Default timeout if none supplied is
zero, resulting in single-stepping.
2017-06-24 Graham Markall <graham.markall@embecosm.com>
Partially-working implementation of Picorv32
Reading and writing memory and registers works, as does
single-stepping instructions. Breakpoints are not presently
working.
* server/GdbServer.cpp: (RISCV_PC_REGNUM) Remove, as it seems a
bit specific to Picorv32 (it handles the PC differently to the
rest of the register file).
* targets/picorv32/Picorv32.cpp: (RISCV_PC_REGNUM) Add.
(resume) Implement, but only single-stepping - no mutiple steps
with timeouts. (terminate) Add comment. (reset)
Implement. (readRegister, writeRegister) Fix handling of PC, which
is a special case.
2017-06-24 Graham Markall <graham.markall@embecosm.com>
* targets/picorv32/Picorv32.cpp: (readRegister, writeRegister)
(read, write) Implement.
2017-06-24 Graham Markall <graham.markall@embecosm.com>
Although this builds, the Picorv32 implementation is not yet
functioning because the functions of Picorv32 are not yet
implemented. Mostly they will be able to call into the
Picorv32Impl class, but some of the functions will need a little
more work.
class should be very similar to the original Cpu class
implementation, and the Picorv32 class adapts it and implements
the ITarget interface.
Some of the choices made here are not completely future-proof;
when we add a second core (RI5CY) we may have problems with
linking.
* Makefile.in: Regenerate.
* server/Makefile.am: Link with Verilated Picorv32 libraries.
* server/Makefile.in: Regenerate.
* targets/picorv32/Makefile.am: Compile Picorv32.cpp and
Picorv32Impl.cpp. Include target, target/common, and verilated
Picorv32 folders. Don't warn on unused params.
* targets/picorv32/Makefile.in: Regenerate.
* targets/picorv32/Picorv32.cpp: Replace old Cpu implementation
