602a67cbea sim: trace: drop unused trace_one_insn 
Everyone has migrated to the split functions (trace_prefix + trace_generic)
a while ago, so we can drop this one now.

9b6025d169 sim: trace: rename debug_printf fully 
Rather than redirect using a define, just rename the symbol fully.

fa8f87e53b sim: trace: add a basic cpu register class 
The bfin/msp430 ports already had trace logic set up for reading/writing
cpu registers, albeit using different unrelated levels (core & vpu).  Add
a proper register class for these and for other ports.

cf304b56ca sim: trace: add set of system helpers 
Some code paths trace on a system instance and not a cpu instance (like
the events code), so add some helpers for those cases.

e750549018 sim: common: replace SIM_FILTER_PATH with lbasename 
This helper macro has largely the same behavior as libiberty's lbasename.
There is a slight nuance related to colons, but it's not clear what the
point of that is, and the code implies that it just wants the basename.

8d0978fb4b sim: use AS_HELP_STRING everywhere 
This helps standardize the configure --help output.

4953dc2094 sim: trace: do not enable internal debug by default 
Since --trace-debug is for people hacking on the sim sources rather than
people just using the sim, default it to off.  This matches the behavior
of other debug knobs we have.

b50a153264 sim: assume recentish compiler/systems 
Assume the build system supports stdint.h/stdarg.h as those have been
around long enough and we don't care about pre-stdc compilers anymore.

ccd4b2953b sim: common: add basic model assert 
If the configured in default doesn't match a known value, throw an
assertion failure rather than segfaulting deeper down.

f55b33d51b sim: common: use standard intXX_t types for signedXX 
Let's assume that the system supports the POSIX int8/16/32/64_t types
as this collapses the logic significantly.

618b526e31 sim: common: standardize multiple include defines 
We use SIM_xxx_H in most headers, so convert _SIM_xxx_H_ over to it.

57b42d6489 sim: syscall: simplify unknown syscall trace 
Since we always include the raw syscall number when tracing, also
including it in the name when it's unknown is redundant.  Simplify
the code by using a constant string.

7aec3bb968 sim: callback: fix sentinel testing when walking maps 
The new helpers for walking the maps tested the wrong value for exiting
the for loop.  This caused crashes when looking up entries that were not
in the map.

7d5c6c43ca sim: syscall: add common sim_syscall helpers 
Many ports have the same sim syscall logic, so add some helpers to handle
all the common details.  The arches still have to deal with the unpacking
and packing of the syscall arguments, but the rest of the sim<->callback
glue is now shared.

61a0c964e6 sim: syscall: unify memory helpers 
Almost every port implements these two callbacks in the same way, so
unify them in the common layer.

6362a3f875 sim: callback: add human readable strings for debugging to maps 
When tracing, we often want to display the human readable name for the
various syscall/errno values.  Rather than make each target duplicate
the lookup, extend the existing maps to include the string directly,
and add helper functions to look up the constants.

While most targets are autogenerated (from libgloss), the bfin/cris
targets have custom maps for the Linux ABI which need to be updated
by hand.

a348708291 sim: drop -DTRACE from configure 
No code uses this anymore and the symbol conflicts with the new TRACE
helper.  Punt it from configure.

5b064994f0 sim: msp430: use new common trace print helpers 
Replace the "if (TRACE_xxx_P) trace_generic" form with "TRACE_xxx".
The output is the same, but the code is nicer to read.

0054dcd7b6 sim: moxie: use new common trace defines 
Now that there's common helpers for printing trace data, switch to that
to restore the insn tracing support for this target.

bb11f3ed2b sim: trace: add common macros for logging info 
The Blackfin port had some TRACE_xxx macros for easily logging trace data.
Use these as a base for common ones that have a simple form and match the
existing sets of helper macros.

29bc024d07 sim: mips: switch to common WITH_TRACE_ANY_P 
We want to add new common trace helpers including "TRACE", so change the
mips one to the new WITH_TRACE_ANY_P macro since they do the same thing.
 2015-06-12 06:28:17 -04:00
Mike Frysinger
bffcfec8c3 sim: trace: add WITH_TRACE_ANY_P helper 
We have STRACE_ANY_P and TRACE_ANY_P, so add WITH_TRACE_ANY_P to fill
out the API.  This lets us wrap the internal configure symbol.

53d2389fd0 sim: moxie: rename TRACE to MOXIE_TRACE_INSN 
We want to add new common trace helpers including "TRACE", so rename the
moxie one to MOXIE_TRACE_INSN.  This also matches what the code is doing.

db7858e227 sim: cgen: namespace custom trace functions 
The cgen code declares some macros/funcs using the trace_xxx prefix, but
the code isn't generic and only works with cgen targets.  This is blocking
the creation of new common trace functions.

Let's blindly add cgen_xxx prefixes to all these symbols.  Some already
use this convention to avoid conflicts, so it makes sense to align them.
In the future we might want to move some to the common trace core, but
one thing at a time.

c1d8560ea5 sim: msp430: delete unused trace macros 
These macros were copied from the Blackfin port but never used, so delete
them as part of the trace unification work.

83034798de sim: trace: centralize the system tracing 
First we convert the ETRACE_P to STRACE_EVENTS_P.  This means we move from
using the sim_events.trace storage to the common sim_state_base.trace_data
array.  With that deleted, the common trace init code can be simplified so
the sim state works the same as the sim cpu.

ce4eda4a58 sim: trace: add STRACE_xxx_P macros 
These are the parallel to the TRACE_xxx_P macros and fill out the full
set to match the existing debug one.

a6c2a374e0 sim: trace: use existing defines for the useful mask

keep that all unified.

9b9c712ceb sim: trace: create a common WITH_TRACE_P macro

encoding of the WITH_TRACE define in multiple places.

66a19e2f81 sim: frv: drop custom debug mask 
This is the only sim that sets up its own WITH_TRACE mask and it conflicts
with the user setting their own list at configure time.  Drop it to match
all the other sims.

a84f8df0e2 sim: m68hc11: switch to common sim_resume

drop it and pull in the common code.

96eaf29ec4 sim: mn10300: delete unused exception/exited/debug state 
The syscall path was the only code checking the custom exception state
after recent cleanups.  Once we change that to the common engine halt
function, we can delete that state entirely.

This also helps highlight some other dead code that we can cull.

b0e4c8a581 sim: mn10300: use common size types

already that give the right answer.
