Thu Dec 14 18:49:34 1995 Andrew Cagney <cagney@highland.com.au>
* lf.c (lf_print_function_type): New function. Munges a function
type so that the prefix (eg INLINE...) is inserted after the type
but before any `*'.
* igen.c: Change to output functions using this.
Wed Dec 13 23:47:00 1995 Andrew Cagney <cagney@highland.com.au>
FIXME: Emul CHIRP does not correctly implement the find device
function.
FIXME: Emul CHIRP and device do not implement device instance
operations.
Wed Dec 13 23:47:00 1995 Andrew Cagney <cagney@highland.com.au>
* options.c (options_inline): Function to output meaningful
description of the INLINE options.
* configure.in (inline): Replace inline magic numbers with macro
names. Map 1->LOCALS_INLINE and 2->ALL_INLINE.
* inline.h, inline.c: update to use inline method.
* std-config.h (CPU_INLINE), cpu.h, inline.h, inline.c: make cpu.h
inline always.
* std-config.h (EVENTS_INLINE): Inline events in psim.
Wed Dec 13 22:01:21 1995 Andrew Cagney <cagney@highland.com.au>
* device_table.c (htab_sum_binary): DMA binaries to correct byte
within a page.
Tue Dec 12 22:51:18 1995 Andrew Cagney <cagney@highland.com.au>
* psim.c (psim_merge_device_file): Change `=' to `==', was this an
error?
Tue Dec 5 11:56:14 1995 Andrew Cagney <cagney@highland.com.au>
* ppc-instructions (ppc_nr_mtcrf_crs, ppc_branch_conditional_name,
ppc_function_unit_name): Simplify by declaring these arrays as
pure and simple static (instead of STATIC_MODEL).
Tue Dec 5 00:45:34 1995 Andrew Cagney <cagney@highland.com.au>
* sim_calls.c (sim_create, sim_load), main.c (main), psim.c: Pass
an options device into psim_create() so that options can be merged
into the tree.
* device.c (*add*): Change semantics so the add functions only add
when the new device (or property) doesn't already exist. This
allows merging of options and data.
Mon Dec 4 17:12:13 1995 Andrew Cagney <cagney@highland.com.au>
* Makefile.in (BASICS_H): Didn't include basics.h in the list of
header files to depend on.
Mon Dec 4 17:12:13 1995 Andrew Cagney <cagney@highland.com.au>
* std-config.h: (*_MODULE): Extend the <module>_inline macro's so
that they also allow control over static functions. Rewrite
document to reflect this.
* std-config.h: (INLINE): Simplify definition, the above and
earlier changes to igen.h eliminate the need to be defensive about
enabling the inline of static functions.
* std-config.h: (SIM_ENDIAN_INLINE, BITS_INLINE): Document limited
suport for inlineing of modules for all callers. Adjust relevant
macro's so that DEFAULT_INLINE will enable this.
* basics.h: Re-order #includes and definitions so that c-code for
basic include files does not call functions delcared in later
#includes.
* basics.h (__attribute__), sim_callbacks.h: Move attribute macro
to basics.h and add hack (include <stdio.h>) to try and bring that
and other possible conflicting macros into scope much earler.
* sim-endian.h,c (SIM_ENDIAN_INLINE) bits.h,c (BITS_INLINE):
Change to use the updated inline definitions. If enabled
immediatly include the corresponding c-code so that it will inline
for all modules.
* inline.h, inline.c (SIM_ENDIAN_INLINE, BITS_INLINE): Remove
these cases, moved to module specific header files.
Sat Dec 2 18:37:51 1995 Andrew Cagney <cagney@highland.com.au>
* vm.c, vm_n.c: Fix htab code.
* vm.c (vm_data_map_read_buffer): Was using EA not RA when reading
the data from core.
* device.c: Fix htab create code.
Fri Nov 24 23:10:09 1995 Andrew Cagney <cagney@highland.com.au>
* bits.h, bits.c (EXTRACTED): Convert to function, fix - had &&
instead of &.
* sim-endian.h (SWAP_N), sim-endian-n.h, sim-endian.c: How
embarasing - fix yet another bug in the swap code! Simplify
everything by using more functions. Add host to big-endian byte
swapping support.
Fri Nov 24 23:10:09 1995 Andrew Cagney <cagney@highland.com.au>
* devices.h, devices.c: delete, replaced by the files
device_table.[ch] and device.[ch].

* device_table.h, device_table.c: New files. Contain a table of
devices.
* device.h, device.c, Makefile.in, std-config.h (DEVICE_INLINE),
options.c (print_options): New files. Define the device object
along with any attached properties.
* device_tree.h, device_tree.c: Update to use new device object.
For convenience, change the printd functions into device_tree_add
functions.
* psim.c (create_*_tree): Use new device_tree create functions.
* corefile.h, corefile.c corefile-n.h (core_n.h): Update to use
the new device.h / device_table.h interface. Rename core_n.h to
corefile-n.h to be consistent with other n files.
* Makefile.in (run): add corefile-n.h to dependencies for
corefile.
* basics.h (device_instance), device.h, device.c, device_table.h,
device_table.c: Add the concept of a device instance and operators
on these instances - corresponds to ihandle in OpenBoot speak.
Don't yet implement it.
Tue Nov 14 12:27:08 1995 Andrew Cagney <cagney@highland.com.au>
* emul_generic.h, emul_generic.c (emul_syscall_enter,

inline.h, inline.c: New to allow control over inline of
corresponding code files.
* ppc-instructions (instruction_call): Add illegal instruction to
call the instruction-call emulation handler.
* interrupts.c (system_call_interrupt): Call renamed
os_emul_system_call function().
* emul_netbsd.c: Update to interface to generic emulation. Since
all its functions are called via a table don't worry about any
inline.
* emul_generic.h, emul_generic.c, spa-*(delete): Remove references
and code for spa, no longer to be used.
* psim.c (create_chirp_device_tree): Fill out what was previously
the openboot create function so that it starts to create a full
OpenBoot device tree.
Tue Nov 28 21:48:06 1995 Andrew Cagney <cagney@highland.com.au>
* debug.h, debug.c: pte trace is made redundant by htab trace,
delete it. Add vm to list of options. Simplify tracing output so
lines are not as long.
Tue Nov 14 12:27:08 1995 Andrew Cagney <cagney@highland.com.au>
* events.h, events.c (event_queue_init), psim.c (psim_init): (re)

KNOWN FEATURES
KNOWN FEATURES:
SMP: A Symetric Multi-Processor configuration is suported. This
includes modeling of the PowerPC load word and reserve instructions
(if intending to use this feature you are well advised to read the the
source code for the reservation instructions so that you are aware of
any potential limitations in the model). The number of processors is
selected during startup.
SMP: It is possible to configure this simulator so that it implements
a restricted model of a Symetric Multi-Processor architecture. It is
important to note that the SMP model has limitations. In particular,
the PowerPC's load word and reserve (etc) instructions do not model
the behavour defined in the Architecture manual. People intending to
use this feature should read the code implementing those instructions.
DUAL-ENDIAN: Both little and big endian models are suported. The
execution of instruction sequences that switch between the two modes,
however, is not. The endianess is selected during startup.
ENDIAN SUPORT: Pure big, pure little and PowerPC little endian (xor
endian) models are suported.
UIEA, VEA and OEA: The PowerPC architecture defines three levels of
the PowerPC architecture. This simulator, to a reasonable degree, is
capable of modeling all three. That is the User Instruction Set
Architecture, the Virtual Environment Architecture and finally the
Operating Environment Architecture. The environment is selected
during startup. The OEA model is still under development.
Operating Environment Architecture.
HARDWARE DEVICE TREE: In the OEA, the model of the target machines
hardware is built from a tree of devices (bit like Open Boot).
Included in this is the ability to model bus hierachies and
runtime-configurable devices (eg PCI). The device tree used to create
the hardware model is created during startup. This device tree is
still under development.
runtime-configurable devices (eg PCI).
VEA SYSTEM CALLS: In user mode, basic system calls (read, write, open,
close ...) are emulated. Under NetBSD (simply because that is what my
machine at home runs) the list is more extensive.
OS EMULATION: Suport for os/firmware emulations (system or rom-calls)
is included. At present limited implemtations of two emulations are
included:NetBSD (UEA model) and OpenBoot (OEA model).
PEDANTIC VEA MEMORY MODEL: This model implements the break (brk, sbrk)
system calls. Further, the user model has very strict memory access
controls. User programs can not assume that they can stray off the
end of valid memory areas. This model defines valid memory addresses
in strict accordance to the executable and does not page allign their
values. At first this was a bug but since then has turned up several
problems in user code so it is now described as a feature.

PROFILING: The simulation is able to count the number and type of
instructions issued and the number of loads and stores. This feature
is still under development.
PERFORMANCE MONITORING: This simulation is able to monitor things such
as cpu/io read/writes and register allocation.

PERFORMANCE: In its default configuration PSIM is configured so that
it will compile fast and run slow. Through the enabling of more
agressive compile options (and the disabling of unwanted features) the
build can be changed to compile slow and run fast.

/* Data transfers:
A device may permit the reading/writing (IO) of its registers in
one or more address spaces. For instance, a PCI device may have
config registers in its config space and control registers in both
the io and memory spaces of a PCI bus.
Similarly, a device may initiate a data transfer (DMA) by passing
such a request up to its parent.
Init:
As part of its initialization (not creation) and possibly also as a
consequence of IO a device may attach its self to one or more of
the address spaces of its parent device.
For instance, a PCI device, during initialization would attach its
config registers (space=0?, base=0, nr_bytes=64) to its parent PCI
bridge. Later, due to a write to this config space, the same
device may in turn find it necessary to also attach its self to
it's parent's `memory' or `io' space.
To perform these operations, a device will call upon its parent
using either device_attach_address or device_detach_address.
* Any address specified is according to what the device expects to
see.
* Any detach operation must exactly match a previous attach.
* included with the attach or detach is the devices name, the
parent may use this as part of determining how to map map between a
child's address + space and its own.
* at any time, at most one device can have a default mapping
registered.
IO:
A device receives requests to perform reads/writes to its registers
or memory either A. from a processor or B. from a parent device.
The device may then in turn either A. resolve the IO request
locally by processing the data or trigering an exception or
B. re-mapping the access onto one of its local address spaces and
then in turn passing that on to one of its children.
* Any address passed is relative to the local device. Eg for PCI
config registers, the address would (normally) be in the range of 0
to 63.
* Any exception situtation triggered by an IO operation (processor
!= NULL) is handled in one of the following ways: 1. Machine check
(and similar): issued immediatly by restarting the cpu; 2. External
exception: issue delayed (using events.h) until the current
instruction execution cycle is completed; 3. Slave device (and
similar): the need for the interrupt is passed on to the devices
parent (which being an interrupt control unit will in turn take one
of the actions described here); 4. Forget it.
* Any exception situtation trigered by a non IO operation
(processor == NULL) is handled buy returning 0.
* Transfers of size <= 8 and of a power of 2 *must* be correctly
aligned and should be treated as a `single cycle' transfer.
DMA:
A device initiates a DMA transfer by calling its parent with the
request. At the top level (if not done earlier) this is reflected
back down the tree as io read/writes to the target device.
This function is subject to change ...

by the device should be created/initialized.
2. It is initialized. Before a simulation run, each device in the
device tree is initialized in prefix order. As part of this
initialization, a device should (re)attach its self to its parent
as needed.

/* Data transfers:
A device may permit the reading/writing (IO) of its registers in
one or more address spaces. For instance, a PCI device may have
config registers in its config space and control registers in both
the io and memory spaces of a PCI bus.
Similarly, a device may initiate a data transfer (DMA) by passing
such a request up to its parent.
Init:
As part of its initialization (not creation) and possibly also as a
consequence of IO a device may attach its self to one or more of
the address spaces of its parent device.
For instance, a PCI device, during initialization would attach its
config registers (space=0?, base=0, nr_bytes=64) to its parent PCI
bridge. Later, due to a write to this config space, the same
device may in turn find it necessary to also attach its self to
it's parent's `memory' or `io' space.
To perform these operations, a device will call upon its parent
using either device_attach_address or device_detach_address.
* Any address specified is according to what the device expects to
see.
* Any detach operation must exactly match a previous attach.
* included with the attach or detach is the devices name, the
parent may use this as part of determining how to map map between a
child's address + space and its own.
* at any time, at most one device can have a default mapping
registered.
IO:
A device receives requests to perform reads/writes to its registers
or memory either A. from a processor or B. from a parent device.
The device may then in turn either A. resolve the IO request
locally by processing the data or trigering an exception or
B. re-mapping the access onto one of its local address spaces and
then in turn passing that on to one of its children.
* Any address passed is relative to the local device. Eg for PCI
config registers, the address would (normally) be in the range of 0
to 63.
* Any exception situtation triggered by an IO operation (processor
!= NULL) is handled in one of the following ways: 1. Machine check
(and similar): issued immediatly by restarting the cpu; 2. External
exception: issue delayed (using events.h) until the current
instruction execution cycle is completed; 3. Slave device (and
similar): the need for the interrupt is passed on to the devices
parent (which being an interrupt control unit will in turn take one
of the actions described here); 4. Forget it.
* Any exception situtation trigered by a non IO operation
(processor == NULL) is handled buy returning 0.
* Transfers of size <= 8 and of a power of 2 *must* be correctly
aligned and should be treated as a `single cycle' transfer.
DMA:
A device initiates a DMA transfer by calling its parent with the
request. At the top level (if not done earlier) this is reflected
back down the tree as io read/writes to the target device.
This function is subject to change ...

/* Interrupts:
The code below handles two different types of interrupts.
Synchronous and Asynchronous.
Synchronous:
Interrupts that must immediately force either an abort or restart
of a current instruction are implemented by forcing an instruction
restart. (or to put it another way, long jump). In looking at the
code it may occure to you that, for some interrupts, they could
return instead of restarting the cpu (eg system_call). While true
(it once was like that) I've decided to make the behavour of all
interrupt routines roughly identical.
Because, a cpu's recorded state (ie what is in the cpu structure)
is allowed to lag behind the cpu's true current state (eg PC not
updated) sycnronous interrupt handers are parameterized with the
the cpu being interrupted so that, as part of moddeling the
interrupt, the cpu's state can be updated.
Asynchronous:

* fmt_error - the name of an error : 0, EISDIR, -1
* fmt_open_flags - the flags to open : O_RDONLY, O_WRONLY|0x14, 0xffffffff
* fmt_unknown - representation unknown : .., .., ..
* fmt_string - if the null termintated string at word is printable displays
* the string within quotes, otherwise displays like fmt_ptr
* fmt_post_string - displays like fmt_ptr, value of word is also saved,
* following the system call a printable string exists at
* address word the address and the string will be displayed
* fmt_data - only permitted in argument lists, next argument must be
* format_data_size, if printable data exists at word having length
* specified by the next argument it is printed, otherwise displays
* like fmt_ptr
* fmt_data_size - displays like FMT_SIZE
* fmt_post_data - displays like fmt_ptr, value of word is also saved,
* following call if a printable length delimited string exists
* it will be displayed
* fmt_post_data_size - displays like FMT_SIZE, value is saved for use as
* length for fmt_post_data display format
* fmt_string_array - word is the address of a null terminted array of strings
* to be printed if possible
*
* Unlike the string formats which typically represent filenames it is not so
* important that length delimited data be fully displayed. When printable,
* it will be truncate much more harshly than the string formats.
*
* Only one item can be pending for display at the end of a system call.
*
* At a later date this program may be extended to display length delimited
* data as a hex dump if it is not printable.
*
* The following macros are employed to make it easy to alter how a whole
* class of values is displayed by changing their definition.
*
* FMT_STATUS - function calls that return 0 on success and -1 on error
* FMT_FLAGS - bit field objects
* FMT_SIZE - length of an object in bytes

GCC -O3 attempts to inline any function or procedure in scope. The
options below facilitate fine grained control over what is and what
isn't made inline. For instance it can control things down to a

two parts. Doing this allows the compiler to both eliminate the

to both eliminate the overhead of function calls and (as a

Experementing with CISC (x86) I've found that I can achieve an
order of magintude speed improvement (x3-x5). In the case of RISC
(sparc) while the performance gain isn't as great it is still
significant.
On a CISC (x86) I've found that I can achieve an order of magintude
speed improvement (x3-x5). In the case of RISC (sparc) while the
performance gain isn't as great it is still significant.
Part One - Static functions: It is possible to control how static
functions within each module are to be compiled. On a per module
or global basis, it is possible to specify that a modules static
functions should be compiled inline. This is controled by the the
macro's STATIC_INLINE and INLINE_STATIC_<module>.
Each module is controled by the macro <module>_INLINE which can
have the values described below
Part Two - External functions: Again it is possible to allow the
inlining of calls to external functions. This is far more
complicated and much heaver on the compiler. In this case, it is
controled by the <module>_INLINE macro's. Where each can have a
value:
0 Do not inline any thing for the given module
0 Make a normal external call to functions in the module.
The following additional values are `bit fields' and can be
combined.
1 Include the module but to not inline functions within it.
This allows functions within the module to inline functions
from other modules that have been included.
1 Include the C file for the module into the file being compiled
but do not make the functions within the module inline.
2 Both include the module and inline functions contained within
it.
While of no apparent benefit, this makes it possible for the
included module, when compiled to inline its calls to what
would otherwize be external functions.
Finally, this is not for the faint harted. I've seen GCC get up to
200mb trying to compile what this can create */
2 Make external functions within the module `inline'. Thus if
the module is included into a file being compiled, calls to
its funtions can be eliminated. 2 implies 1.
4 Make internal (static) functions within the module `inline'.
In addition to this, modules have been put into two categories.
Simple modules - eg sim-endian.h bits.h
Because these modules are small and simple and do not have
any complex interpendencies they are configured, if
<module>_INLINE is so enabled, to inline themselves in all
modules that include those files.
For the default build, this is a real win as all byte
conversion and bit manipulation functions are inlined.
Complex modules - the rest
These are all handled using the files inline.h and inline.c.
psim.c includes the above which in turn include any remaining
code.
IMPLEMENTATION:
The inline ability is enabled by prefixing every data / function
declaration and definition with one of the following:
INLINE_<module>
Prefix to any global function that is a candidate for being
inline.
values - `', `static', `static INLINE'
EXTERN_<module>
Prefix to any global data structures for the module. Global
functions that are not to be inlined shall also be prefixed
with this.
values - `', `static', `static'
STATIC_INLINE_<module>
Prefix to any local (static) function that is a candidate for
being made inline.
values - `static', `static INLINE'
static
Prefix all local data structures. Local functions that are not
to be inlined shall also be prefixed with this.
values - `static', `static'
nb: will not work for modules that are being inlined for every
use (white lie).
extern
#ifndef _INLINE_C_
#endif
Prefix to any declaration of a global object (function or
variable) that should not be inlined and should have only one
definition. The #ifndef wrapper goes around the definition
propper to ensure that only one copy is generated.
nb: this will not work when a module is being inlined for every
use.
STATIC_<module>
Replaced by either `static' or `EXTERN_MODULE'.
REALITY CHECK:
This is not for the faint hearted. I've seen GCC get up to 200mb
trying to compile what this can create.
Some of the modules do not yet implement the WITH_INLINE_STATIC
option. Instead they use the macro STATIC_INLINE to control their
local function.
Because of the way that GCC parses __attribute__(), the macro's
need to be adjacent to the functioin name rather then at the start
of the line vis:
int STATIC_INLINE_MODULE f(void);
void INLINE_MODULE *g(void);
