2021-05-02sim: add default cases to two switches in sim-options.cSimon Marchi2-0/+7
This is the next compilation error I hit when I build all targets with Clang: /home/simark/src/binutils-gdb/sim/aarch64/../common/sim-options.c:234:12: error: no case matching constant switch condition '0' [-Werror] switch (WITH_ENVIRONMENT) ^~~~~~~~~~~~~~~~ ./config.h:215:26: note: expanded from macro 'WITH_ENVIRONMENT' #define WITH_ENVIRONMENT ALL_ENVIRONMENT ^~~~~~~~~~~~~~~ /home/simark/src/binutils-gdb/sim/aarch64/../common/sim-options.c:276:15: error: no case matching constant switch condition '0' [-Werror] switch (WITH_ALIGNMENT) ^~~~~~~~~~~~~~ /home/simark/src/binutils-gdb/sim/aarch64/../common/sim-config.h:220:24: note: expanded from macro 'WITH_ALIGNMENT' #define WITH_ALIGNMENT 0 ^ This is a little bit special because these are switches on compile-time value. But regardless, the idea is that we logically can't reach the switches if WITH_ENVIRONMENT == 0 or WITH_ALIGNMENT == 0, so the code is correct. In addition to getting rid of the compiler warning, adding default cases to these switches ensure that if we do get in an unexpected situation, it is caught. In GDB, I'd use gdb_assert_not_reached, I don't know if there is something similar in sim so I went with abort. sim/common/ChangeLog: * sim-options.c (standard_option_handler): Add default cases to switches.

2021-05-02sim: replace custom attributes with ansidecl.hMike Frysinger20-63/+79
A lot of this code predates the common attributes. We had already started migrating over piece by piece, so just do a pass across all the attributes and replace most of them.
2021-05-01sim: bfin: move option inits to respective modulesMike Frysinger4-13/+30
Now that modules can self declare their own init funcs, change the mmu and mach logic to use it. We don't need to export the option symbols or specifically call this logic from the sim_open function anymore.
2021-05-01sim: options: fix --help outputMike Frysinger2-0/+5
The hash table rewrite broke --help output due to subtle behavior: calling dup_arg_p(NULL) will create & clear the table, not just create it. The --help output relies on this to clear the table before it shows things.
2021-05-01sim: dv-sockser: localize init callbackMike Frysinger4-12/+12

2021-05-01sim: add framework for declaring init callbacks locallyMike Frysinger4-16/+74
To facilitate decentralized module initialization/registration with an eye towards multi-target support, add a framework to detect init calls declared in the source and automatically call them. This is akin to gdb's _initialize_xxx framework for letting modules autodiscover.

2021-05-01sim: nrun: add local strsignal prototypeMike Frysinger97-62/+386

2021-05-01sim: rx: cast bfd_vma when printingMike Frysinger2-1/+5
A bit of a hack, but it's what we've been doing so far when printing bfd_vma's since bfd doesn't provide PRI helper types for us to use.

2021-05-01sim: aarch64: use PRIx64 for formatting 64-bit typesMike Frysinger2-5/+12
We can't assume that %lx is big enough for 64-bit types as it isn't on most 32-bit builds. Use the standard format define for this instead.
2021-05-01sim: aarch64: fix 64-bit immediate shiftsMike Frysinger2-2/+6
Trying to shift immediates 63 bits fails on 32-bit systems since UL is only 32-bits, not 64-bits. Switch to ULL to guarantee at least 64-bits here.
2021-05-01sim: arm: move build logic to source filesMike Frysinger3-9/+25
This simplifies the build logic a bit by just having source file inputs. It also simplifies code that assumes there's a source file for each object.
2021-05-01sim: callback: inline wrap helperMike Frysinger2-25/+66
This is annoying as it requires inlining boiler plate, but we don't have much choice: the wrap helper assumes the return value is always an int, but that's already not the case with some of the callbacks which use long. GCC has extensions to define macros-as-functions, but we can't assume GCC.

2021-04-30Do not separately read type unitsTom Tromey2-133/+69
Currently, the DWARF reader has a separate pass to read type units -- create_all_type_units. While working on other patches, I discovered that this caused DWARF 5 type units to be read twice, once by create_all_comp_units and once by create_all_type_units. There's no need any more (if there ever was) to treat type units differently from CUs. So, this patch removes create_all_type_units and unifies the code paths. Note that the DWO code still has a second pass. I haven't looked into this code yet; perhaps it can also be simplified.

2021-04-30Remove dwarf2_per_bfd::all_type_unitsTom Tromey4-123/+87
I don't think there is any deep reason to separate CUs and TUs in dwarf2_per_bfd. This patch removes all_type_units and unifies these two containers.

2021-04-30Allocate dwarf2_per_cu_data with 'new'Tom Tromey4-208/+265
In a patch series I am working on, I'd like to have a non-POD member in dwarf2_per_cu_data. This currently can't be done because dwarf2_per_cu_data is allocated on an obstack and initialized with memset. This patch changes the DWARF reader to allocate objects of this type with 'new'. The various "subclasses" of this type (signatured_type in particular) are now changed to derive from dwarf2_per_cu_data, and also use 'new' for allocation.

2021-04-29x86: allow @size to also (sensibly) apply to sectionsJan Beulich5-7/+36
So far this (counter-intuitively) produced the size as recorded in the (section) symbol. Obtain the section's size instead for section symbols. (I wonder whether STT_SECTION symbols couldn't properly hold the section's size in their st_size field, which in turn would likely mean the internal symbol would also have its size properly updated.) Note that this is not the same as the .sizeof.() pseudo-operator: @size yields the local file's contribution to a section, while .sizeof.() gets resolved by the linker to produce the final full section's size. As to the 3rd each of the expected output lines in the changed testcase: I can't find justification for zzz to come after yyy despite them being defined in the opposite order in source. Therefore I think it's better to permit both possible outcomes.
