2024-01-03sim: ppc: unify igen filter modulesMike Frysinger10-171/+60
The common igen code was forked from the ppc long ago. The filter module is still pretty similar in API, so we can unfork them with a little bit of effort. The filter.c module is still here because of the unique it_is API. The common igen code doesn't seem to have an equiv API as this only operates on two strings and not an actual filter object, and it's easy enough to leave behind to unfork the rest.
2024-01-03sim: ppc: unify igen line number output modulesMike Frysinger12-665/+145
The common igen code was forked from the ppc long ago. The lf module is still pretty similar in API, so we can unfork them with a little bit of effort. Some of the generated ppc code is now slightly different, but that's because of fixes the common igen code has gained, but not the ppc igen code (e.g. fixing of #line numbers). The ppc code retains lf_print__c_code because the common igen code rewrote the logic to a new table.c API. Let's delay that in the ppc code to at least unfork all this code.
2024-01-03sim: ppc: switch to common endian codeMike Frysinger4-438/+0
The common sim-endian is a forked & updated version of the ppc code. Fortunately, they didn't diverge from the basic APIs, so they are still compatible, which means we can just delete the ppc version now that the build env is merged at the top-level.
2024-01-03sim: ppc: rename local ALU SIGNED64 macrosMike Frysinger1-6/+6
The common/ code has macros with the same name but different behavior: it's for declaring integer constants as 64-bit, not for casting them. Rename ppc's local variant since it's only used in this file in order to avoid conflicts.
2024-01-03sim: ppc: sync WITH_TARGET_{ADDRESS,CELL}_BITSIZE with common/Mike Frysinger1-0/+8
This will make it easier to share common/ code that rely on these additional defines.
2024-01-03sim: ppc: hoist compilation up to top-levelMike Frysinger2-581/+2
This removes all recursive makes from the ppc port.
2024-01-03sim: ppc: move libsim.a creation to top-levelMike Frysinger2-14/+49
The objects are still compiled in the subdir, but the creation of the archive itself is in the top-level. This is a required step before we can move compilation itself up, and makes it easier to review. The downside is that each object compile is a recursive make instead of a single one. It adds some overhead, so it's not great, but it shouldn't be a big deal. This will go away once compilation is hoisted up.
2024-01-03sim: ppc: move main.o compilation to top-levelMike Frysinger2-14/+14
2024-01-02sim: ppc: hoist pk.h creation to top-levelMike Frysinger3-33/+30
2024-01-02sim: ppc: hoist hw.[ch] creation to top-levelMike Frysinger2-35/+45
2024-01-02sim: ppc: hoist igen execution to top-levelMike Frysinger2-62/+64
Invoke ppc's igen from the top-level like we do for all other ports.
2024-01-02sim: ppc: merge configure logic into top-levelMike Frysinger4-3261/+6
Now that the ppc configure script is just namespaced options, we can move it to ppc/acinclude.m4 and include it directly in the top-level configure script and kill off the last subdir configure script.
2024-01-02sim: ppc: scope configure options to --enable-sim-ppc-xxxMike Frysinger3-395/+398
To prepare for moving these into the top-level configure, namespace then with the port name like we do with all other ports.
2024-01-02sim: ppc: standardize configure option processingMike Frysinger2-248/+161
Switch from ad-hoc $silent checks & echo calls to standard AC_MSG_CHECKING & AC_MSG_RESULT calls. Also delete pointless variable setting after calling AC_MSG_ERROR.
2024-01-02sim: ppc: switch to AS_HELP_STRING for automatic formattingMike Frysinger2-36/+51
2024-01-02sim: ppc: drop now unused config.inMike Frysinger1-19/+0
2024-01-02sim: ppc: move defines.h generation to the top-levelMike Frysinger2-8/+11
Since we rely on the top-level config.h now, the defines.h generation step should live here too.
2024-01-02sim: ppc: drop configure compiler checksMike Frysinger2-1118/+1
Now that the ppc script only checks configure options and sets up variables in the Makefile from those, delete all the compile related logic to greatly simplify the configure script.
2024-01-02sim: ppc: drop custom config.h headerMike Frysinger4-255/+50
Now that everything has moved to the top-level, we can drop the custom ppc config.h and reuse the common one.
2024-01-02sim: ppc: stop including headers from gdb/Mike Frysinger1-2/+1
The common sim code doesn't snoop in gdb/, and the ppc code doesn't need to either. Any common code we pull from gnulib/ now only.
2024-01-02sim: ppc: move termios probes to top-levelMike Frysinger3-273/+0
This is the last compile-time logic in the ppc subdir.
2024-01-02sim: ppc: switch to AC_CACHE_CHECKMike Frysinger2-61/+65
This macro replaces the AC_MSG_CHECKING+AC_CACHE_VAL+AC_MSG_RESULT which reduces the boilerplate in here a little bit.
2024-01-02sim: ppc: switch struct member checks to AC_CHECK_MEMBERMike Frysinger2-68/+99
This covers a lot of the AC_MSG_CHECKING+AC_TRY_COMPILE+AC_MSG_RESULT boilerplate and matches what we do in the top-level platform checks.
2024-01-02sim: ppc: move termio defines to config.hMike Frysinger4-15/+28
Move the defines from explicit -D options to config.h defines to simplify the build and make it easier to move to the top-level configure.
2024-01-02sim: ppc: move struct statfs to top-levelMike Frysinger3-71/+0
2024-01-02sim: ppc: move long long test to top-levelMike Frysinger3-651/+2
While the sim code doesn't utilize HAVE_LONG_LONG itself, other code (like libiberty) seem to, so check for it in the top-level for all ports to leverage.
2024-01-02sim: ppc: hoist sysv tests to top-levelMike Frysinger3-189/+1
Now that the sysv tests turn into config.h defines and everything checks that, we can move the tests to the top-level and out of the ppc subdir.
2024-01-02sim: ppc: always compile in the sysv sem & shm device filesMike Frysinger5-14/+46
Move the stub logic to the device files themselves. This makes the configure & build logic more static which will make it easier to move to the top-level build, and matches what we did with the common/ hw tree already. This also decouples the logic from the two -- in the past, you needed both sem & shm in order to enable the device models, but now each one is tied to its own independent knob. Practically speaking, this will probably not make a difference, but it simplifies the build a bit.
2024-01-02sim: ppc: change SysV sem & shm tests to compile-timeMike Frysinger2-110/+87
Instead of executing code to see if SysV semaphores & shared memory are available, switch to just a compile-time test. The system used to compile might not match the system used to run the code wrt the current kernel & OS settings, but the library APIs should. So move the failures from compile-time to runtime so the program is more portable, and works correctly even when cross-compiling.
2024-01-02sim: ppc: merge System V semaphores checksMike Frysinger2-83/+13
Compile tests can use earlier defines, so hoist the HAVE_UNION_SEMUN define to before the semaphore check, and use it in the test so that we can merge the 2 versions into one. This also defines HAVE_UNION_SEMUN even when ac_cv_sysv_sem is not set, but that's OK as this define is only about a type existing, not about whether the overall code is usable.
2024-01-02sim: ppc: fix bad AC_CACHE_CHECK call with semunMike Frysinger2-9/+4
The first arg is the cache var name, and this one was typoed relative to what the call actually set. We also don't need the manual call to AC_MSG_RESULT as the AC_CACHE_CHECK takes care of it for us.
2024-01-02sim: ppc: delete unused build compile & link settingsMike Frysinger1-3/+0
These should have been removed as part of the ppc/igen merging into the top-level, but they were missed. Clean up now.
2024-01-01sim: ppc: merge misc igen APIsMike Frysinger9-286/+73
The common igen code provides the same misc APIs as the ppc version, so delete the ppc code and pull in the common one. There is one minor difference: the ppc code has a unique dumpf function. The common code switched to lf_printf for the same functionality, but since that requires changes throughout the igen codebase, delay that cleanup for now so we can merge the rest.
2024-01-01sim: ppc: rework igen error to match commonMike Frysinger10-22/+25
Switch to an ERROR macro and tweak the error signature to match the common igen version in preparation for merging the two implementations.
2024-01-01sim: ppc: rename igen max_insn_bit_sizeMike Frysinger3-5/+5
We want to avoid conflicts with the common igen enums. This should get migrated over to the common parsing logic, but for now, switch the name to avoid redefinition.
2024-01-01sim: ppc: unify igen filter_filename implementationsMike Frysinger6-84/+4
Now that both igen implementations are in the top-level, we can unify the filter_filename implementation between them since they're the same (literally the same code).
2024-01-01sim: ppc: replace filter_filename with lbasenameMike Frysinger2-15/+8
The lbasename function from libiberty provides the same API as this custom function. The common/ code already made the switch, so make the same change to the ppc code to avoid target duplication.
2024-01-01sim: ppc: hoist igen compilation into top-levelMike Frysinger2-60/+64
This simplifies the build a bit (especially for deps in port subdirs), and avoids recursive make. This in turn speeds up the build, and lets us reuse existing build-time vs host-time logic from Makefile.am.
2024-01-01sim: ppc: drop build-config.h usageMike Frysinger8-73/+0
This header is only used by the igen tool, and none of the igen code depends on the configure-time checks. Delete the logic to simplify to prepare for moving it to the local.mk code.
2024-01-01sim: ppc: simplify filter_host.c logicMike Frysinger2-7/+19
Switch this from a build-time generation to a static include. This makes the build rules a bit simpler, especially as we move them to Automake from hand-written makefiles.
2024-01-01sim: ppc: drop unused host bitsize settingsMike Frysinger3-5/+0
This is never set anywhere, so it's always empty. Scrub it.
2024-01-01sim: fix pervasive typoTom Tromey4-21/+21
I noticed a typo in a sim constant. This patch fixes it. permenant -> permanent
2023-12-22sim: ppc: fix -Wshadow=local warningsMike Frysinger1-3/+3
Use a local name in the macro to avoid shadowing wherever it's used.
2023-12-21sim: ppc: igen: fix -G handlingMike Frysinger1-2/+9
We weren't using the enable_p flag to see whether the option should be enabled or disabled, and we weren't breaking out when done parsing.
2023-12-21sim: ppc: fix -Wimplicit-fallthrough warningsMike Frysinger1-1/+1
Replace some fall through comments with the attribute.
2023-12-21sim: add ATTRIBUTE_FALLTHROUGH for local codeMike Frysinger1-0/+3
We'll replace various /* fall through */ comments so compilers can actually understand what the code is doing.
2023-12-21sim: ppc: phb: add missing break to address decoderMike Frysinger1-0/+1
I don't know what this emulation does exactly, but it missing a break statement seems kind of obvious based on the 32-bit case above it.
2023-12-21sim: ppc: mark halt & restart funcs as noreturnMike Frysinger3-6/+6
This helps the compiler with optimization and fixes fallthru warnings.
2023-12-07sim: ppc: fix -Wunused-but-set-variable warningsMike Frysinger1-2/+0
2023-12-04sim: ppc: fix implicit enum conversionMike Frysinger1-3/+3
This code tries to use attach_type enums as hw_phb_decode, and while they're setup to have compatible values, the compiler doesn't like it when the cast is missing. So cast it explicitly and then use that. sim/ppc/hw_phb.c:322:28: error: implicit conversion from enumeration type 'attach_type' (aka 'enum _attach_type') to different enumeration type 'hw_phb_decode' [-Werror,-Wenum-conversion]
