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.

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.
(ft32_analyze_prologue): Use ft32_fetch_instruction().
sim/ChangeLog:
* ft32/interp.c (step_once): Add ft32 shortcode decoder.

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.

Now that cconfig.h doesn't exist, there's no need to build in the common
subdir anymore. We leave the configure/Makefile files in there as there
is a helper for developers to generate the nltvals.def file. Once that
gets cleaned up in the future though, we can drop the build logic too.
|
|
The common subdir sets up a cconfig.h file to hold checks for the common
code. In practice, most files still end up using config.h instead which
just leads to confusion.
Merge all the configure checks that went into cconfig.h into SIM_AC_COMMON
so we can drop the cconfig.h file altogether. Now there is only a single
config.h file like normal.
|
|
|
|
The simulator is including syscall.h which is not standard and apparently
not required (builds correctly without it on my machine).
|
|
No arch is using this anymore, and we want all new ports using the
hardware framework instead. Punt WITH_DEVICES and the two callbacks
device_io_{read,write}_buffer.
We can also punt the tconfig.h file as no port is using it anymore.
This fixes in-tree builds that get confused by picking up the wrong
one (common/ vs <port>/) caused by commit ae7d0cac8ce971f7108d270c.
Any port that needs to set up a global define can use their own
sim-main.h file that they must provide regardless.

Since the testsuite subdir has to handle dynamic arch values already,
there's no real value in requiring arches to opt in to it. Most have
a testsuite now anyways, and we're requiring it in the future.
|
|
Just enough to know the sim isn't totally broken.
|
|
FT32 is a new high performance 32-bit RISC core developed by FTDI for
embedded applications.
|
|
Rather than manually include tconfig.h when we think we'll need it (which
is error prone as it can define symbols we expect from config.h), have it
be included directly by config.h. Since we know we have to include that
header everywhere already, this will make sure tconfig.h isn't missed.
It should also be fine as tconfig.h is supposed to be simple and only set
up a few core defines for the target.
This allows us to stop symlinking it in place all the time and just use
it straight out of the respective source directory.
