2022-11-05sim: build: move install steps to the top-levelMike Frysinger8-103/+107
We still have to maintain custom install rules due to how we rename arch-specific files with an arch prefix in their name, but we can at least unify the logic in the common dir.
2022-11-05sim: cris: move rvdummy linking to top-levelMike Frysinger3-56/+77
This is only used by `make check`, so we can move it out of the default build too.
2022-11-05sim: build: add SIM_HW_CFLAGS to top-level build tooMike Frysinger2-3/+6
This matches what we do with targets already.
2022-11-05sim: drop unused SIM_HARDWARE variableMike Frysinger1-2/+1
This hasn't been used since the refactor way back in commit f872d0d643968c1101bb8c07b252edd54f626da2 ("Only enable H/W on some mips targets."), so punt it.
2022-11-05sim: adjust sim_hw options styleMike Frysinger4-8/+12
We use uppercase for other variables, and are already turning it to uppercase in the arch-subdir.mk, so convert it in the configure step.
2022-11-05sim: ppc: drop unused /dev/zero logicMike Frysinger4-84/+1
Nothing in the tree checks this option, or has checked for decades. The pre-cvs-import ChangeLog suggests this was added & removed back then, but can't be sure as that history doesn't exist in the VCS.
2022-11-05sim: ppc: delete unused host bitsize settingsMike Frysinger4-32/+2
Nothing checks this define anywhere, so drop all the logic. We don't want this to be a configure option in the first place as all such usage should be automatic & following proper types.
2022-11-05sim: ppc: inline the sim-packages optionMike Frysinger4-63/+12
This has only ever had a single option that's enabled by default. The objects it adds are pretty small and don't add overhead at runtime if it isn't used, so just enable it all the time to make the build code simpler.

2022-11-04[testsuite] gdb.base/dlmopen: Fix test name and use gdb_attachLancelot SIX1-1/+3
One test name in gdb.base/dlmopen.exp changes from run to run since it includes a process id: PASS: gdb.base/dlmopen.exp: attach 3442682 This is not convenient do diff gdb.sum files to compare test runs. Fix by using gdb_attach helper function to handle attaching to the process as it produce a constant test name. While at it also check gdb_attach's return value to only run the rest of the test if the attach was successful. Approved-By: Simon Marchi <simon.marchi@efficios.com>
2022-11-04PowerPC update comments for the MMA instruction name changes.Carl Love3-30/+56
The mnemonics for the pmxvf16ger*, pmxvf32ger*,pmxvf64ger*, pmxvi4ger8*, pmxvi8ger4*, and pmxvi16ger2* instructions were officially changed to pmdmxbf16ger*, pmdmxvf32ger*, pmdmxvf64ger*, pmdmxvi4ger8*, pmdmxvi8ger4*, pmdmxvi16ger* respectively.

The above commit results in about 224 failures on Power 10 since the disassembled names do not match the expected names in the test.

There are no functional changes in file gdb.arch/powerpc-power10.c.
2022-11-04Powerpc fix for gdb.base/unwind-on-each-insn.expCarl Love1-0/+22
The test disassembles function foo and searches for the line "End of assembler dump" to determing the last address in the function. The assumption is the last instruction will be given right before the line "End of assembler dump". This assumption fails on PowerPC. The PowerPC disassembly of the function foo looks like: Dump of assembler code for function foo: # => 0x00000000100006dc <+0>: std r31,-8(r1) # 0x00000000100006e0 <+4>: stdu r1,-48(r1) # 0x00000000100006e4 <+8>: mr r31,r1 # 0x00000000100006e8 <+12>: nop # 0x00000000100006ec <+16>: addi r1,r31,48 # 0x00000000100006f0 <+20>: ld r31,-8(r1) # 0x00000000100006f4 <+24>: blr # 0x00000000100006f8 <+28>: .long 0x0 # 0x00000000100006fc <+32>: .long 0x0 # 0x0000000010000700 <+36>: .long 0x1000180 # End of assembler dump. The blr instruction is the last instruction in function foo. The lines with .long following the blr instruction need to be ignored. This patch adds a new condition to the gdb_test_multiple "disassemble foo" test to ignore the lines with the .long. The patch has been tested on PowerPC and Intel X86-64.

2022-11-04opcodes/arm: silence compiler warning about uninitialized variable useAndrew Burgess1-1/+3
After this commit: commit 6576bffe6cbbb53c5756b2fccd2593ba69b74cdf Date: Thu Jul 7 13:43:45 2022 +0100 opcodes/arm: add disassembler styling for arm Some people were seeing their builds failing with complaints about a possible uninitialized variable usage. I previously fixed an instance of this issue in this commit: commit 2df82cd4b459fbc32120e0ad1ce19e26349506fe Date: Tue Nov 1 10:36:59 2022 +0000 opcodes/arm: silence compiler warning about uninitialized variable use which did fix the build problems that the sourceware buildbot was hitting, however, an additional instance of the same problem was brought to my attention, and that is fixed in this commit. Where commit 2df82cd4b4 fixed the uninitialized variable problem in print_mve_unpredictable, this commit fixes the same problem in print_mve_undefined. As with the previous commit, I don't believe we could really ever get an uninitialized variable usage, based on the current usage of the function, so I have just initialized the reason variable to "??".
2022-11-04sim: rx: drop unused $arch settingMike Frysinger1-2/+0
This is only needed for CGEN ports which RX isn't, so drop it.
2022-11-04sim: build: remove various obsolete generation dep variablesMike Frysinger13-239/+4
These manual settings were necessary when we weren't doing automatic header dependency tracking. That was changed a while ago, and we use automake now to do it all for us. As a result, many of these vars aren't even referenced anymore. Further, some of the source file generation (e.g. .c files, or igen, or cgen outputs) were moved to the common automake build, and it takes care of dependency tracking for us with the object files.
2022-11-04sim: don't hardcode -ldl for SDL supportMike Frysinger4-11/+17
Since we use AC_SEARCH_LIBS to find dlopen, we don't need to hardcode -ldl when using SDL ourselves.

2022-11-04sim: drop -lm from SIM_EXTRA_LIBSMike Frysinger7-9/+2
We have configure tests for this in the top-level configure script to link this when necessary, so we don't need to explicitly list it for specific ports.
2022-11-04sim: build: change AC_CHECK_LIB to AC_SEARCH_LIBSMike Frysinger3-107/+150
With more C libraries moving functions entirely into the main -lc, change the AC_CHECK_LIB calls to AC_SEARCH_LIBS so we look in there first and avoid extra linkage when possible.
2022-11-04sim: build: drop duplicate $(LIBS) usageMike Frysinger1-2/+1
COMMON_LIBS is set to $(LIBS), and CONFIG_LIBS is set to that plus @LIBS@. This leds to the values being used twice. Inline the CONFIG_LIBS variable without @LIBS@ since it's used only once.
2022-11-04sim: build: switch to bfd & opcodes libtool linker scriptsMike Frysinger9-431/+18
Now that we use libtool to link, we don't need to duplicate all the libs that bfd itself uses. This simplifies the configure & Makefile.
2022-11-04sim: build: switch to libtool for linkingMike Frysinger4-7/+19
The top-level already sets up a libtool script for the host, so use that when linking rather than invoking CC directly. This will also happen when we (someday) move the building to pure automake.

2022-11-04sim: testsuite: fix cris stat3 in diff setupsMike Frysinger1-6/+10
This test uses the test itself as an input to stating regular files. This gets funky though: when we run check in parallel, the output object dir is the subdir that matches the .exp file. When we run with -j1, the output object dir is the sim builddir itself. The old test would append argv[0] to find the file, while the new test uses basename on it. Each method works in only one of the aforementioned build scenarios. Rather than complicate this any more, switch to a different file that we know will always exist: the Makefile.
2022-11-04sim: testsuite: fix cris badarch in multi-target buildsMike Frysinger1-1/+1
This test assumes that /bin/sh will never be a CRIS ELF by way of assuming that the current bfd cannot load it (since a basic cris cross-compiler only understands CRIS ELFs). In a multi-target build though, bfd understands just about every ELF out there, so we're able to read the /bin/sh format before failing at a diff point in the cris code. Let's switch to using / instead since it'll fail for a similar reason (at least similar enough for what this test is testing).
2022-11-04sim: cleanup unused SIM_EXTRA_CFLAGSMike Frysinger3-7/+0

2022-11-04sim: m32c/rx: drop useless $(ENDLIST)Mike Frysinger2-10/+4
This is used to allow for dangling \ in object lists, but these are the only ports that do it, and it isn't really necessary. Punt it to keep the various makefiles harmonized.
2022-11-04sim: mips: simplify fpu configure logicMike Frysinger2-22/+14
The configure code always defaults to HARD_FLOATING_POINT, so inline that value and drop redundant target checks as a result.
2022-11-04sim: erc32: link sis to run programMike Frysinger1-6/+3
The erc32 sim does a lot itself, including handling of the CLI. It used to provide a run-compatible interface in the pre-nrun days, but it was dropped when the old run interface was punted. Since the old commit 465fb143c87076b6416a8d0d5dd79bb016060fe3 ("sim: make nrun the default run program"), the erc32 run & sis programs have been the same, and erc32 hasn't provide a real run-compatible interface. Simplify this by linking the two programs via ln/cp instead of running the linking phase twice to produce the same result. If/when we fix up the erc32 port to have a proper run interface, it should be easy to split these back apart into real programs. Note: the interf.o reference in here is a bit of a misdirect. Since that object is placed into libsim.a, it's never been linked into the programs since the linker ignores objects that aren't referenced, and only gdb uses those symbols.

2022-11-03sim: v850: switch to standard (high-level) trace definesMike Frysinger3-6/+2
The v850 port uses -DDEBUG to control whether to enable internal tracing. We already have such options via the common trace framework, and those can be controlled at build time via configure flags (which the v850 code currently cannot). So switch it over to WITH_TRACE_ANY_P to simplify the v850 build code even if it doesn't (yet) respect any other trace options.

2022-11-03gdb: Fix issue with Clang CLI macrosBruno Larsen10-11/+179
Clang up to version 15 (current) adds macros that were defined in the command line or by "other means", according to the Dwarf specification, after the last DW_MACRO_end_file, instead of before the first DW_MACRO_start_file, as the specification dictates. When GDB reads the macros after the last file is closed, the macros never end up "in scope" and so we can't print them. This has been submitted as a bug to Clang developers (https://github.com/llvm/llvm-project/issues/54506), and PR macros/29034 was opened for GDB to keep track of this. Seeing as there is no expected date for it to be fixed, add a workaround for all current versions of Clang. The workaround detects when the main file would be closed and if the producer is Clang, and turns that operation into a noop, so we keep a reference to the current_file as those macros are read. A test case was added to confirm the functionality, and the KFAIL for running gdb.base/macro-source-path when using clang.

2022-11-03sim: move common flags to default AM_CPPFLAGSMike Frysinger5-175/+39
Since all host files we compile use these settings, move them out of libcommon.a and into the default AM_CPPFLAGS. This has the effect of dropping the custom per-target automake rules. Currently it saves us ~150 lines, but since it's about ~8 lines per object, the overhead will increase quite a bit as we merge more files into a single build. This also changes the object output names, so we have to tweak the rules that were pulling in the common objects when linking.

A bunch of these paths don't include any headers, and most likely never will, so there's no real need to keep them. This will let us harmonize paths with the top-level Makefile more easily, which will in turn make it easier to move more compile steps there.
