2024-01-03sim: ppc: unify igen filter modulesMike Frysinger1-1/+1
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 Frysinger1-6/+6
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.
2024-01-01sim: ppc: rework igen error to match commonMike Frysinger1-2/+2
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 Frysinger1-2/+2
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: drop build-config.h usageMike Frysinger1-1/+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.
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.
2023-12-04sim: ppc: fix -Wmisleading-indentation warningsMike Frysinger1-1/+1
Fix building with -Wmisleading-indentation.
2022-10-29sim, sim/{m32c,ppc,rl78}: Use getopt_longTsukasa OI1-3/+6
Because of a Libiberty hack, getopt on GNU libc (2.25 or earlier) is currently unusable on sim, causing a regression on CentOS 7. This is caused as follows: 1. If HAVE_DECL_GETOPT is defined (getopt declaration with known prototype is detected while configuration), a declaration of getopt in "include/getopt.h" is suppressed. The author started to define HAVE_DECL_GETOPT in sim with the commit 340aa4f6872c ("sim: Check known getopt definition existence"). 2. GNU libc (2.25 or earlier)'s <unistd.h> includes <getopt.h> with a special purpose macro defined to declare only getopt function but due to include path (not tested while configuration), it causes <unistd.h> to include Libiberty's "include/getopt.h". 3. If both 1. and 2. are satisfied, despite that <unistd.h> tries to declare getopt by including <getopt.h>, "include/getopt.h" does not do so, causing getopt function undeclared. Getting rid of "include/getopt.h" (e.g. renaming this header file) is the best solution to avoid hacking but as a short-term solution, this commit replaces getopt with getopt_long under sim/.
2022-10-19sim/ppc: fix warnings related to printf format stringsAndrew Burgess1-1/+1
This commit is a follow on to: commit 182421c9d2eea8c4877d983a2124e591f0aca710 Date: Tue Oct 11 15:02:08 2022 +0100 sim/ppc: fixes for arguments to printf style functions where commit 182421c9d2ee addressed issues with printf format arguments that were causing the compiler to give an error, this commit addresses issues that caused the compiler to emit a warning. This commit is mostly either changing the format string to match the argument, or in some cases, excess, unused arguments are removed.
2021-10-31sim: ppc: use silent build rules here tooMike Frysinger1-0/+2
The ppc codebase is unique and doesn't leverage common/, so have to add silent rules to it specifically.
2021-06-17sim: ppc: avoid "PAGE_SIZE" nameMike Frysinger1-1/+1
This define is used for a particular target and depends on the simulated CPU hardware. It has no relation to the host CPU that the sim is running on. So rename the common "PAGE_SIZE" here to better reflect its usage and avoid conflicts with system headers.
2021-05-15sim: ppc: clean up various warningsMike Frysinger1-0/+1
A random grab bag of minor fixes to enable -Werror for this port. Cast address vars to long when the format was using %l. Use %zu with sizeof operations. Add const to a bunch of strings. Trim unused variables. Fix sizeof call to calculate target storage and not the pointer itself.
2021-01-04sim: include stdlib.h for atoi()Mike Frysinger1-2/+1
Make sure the files using atoi() include stdlib.h for its prototype. These files were relying on it being included implicitly by others which isn't guaranteed, and newer toolchains produce warnings.
