The --extension feature requires that all symbols in extension.o
be available when the libraries are dynamically loaded by dlopen.
Prepending extension.o to the linker command adds the otherwise
omitted symbols to spike's dynamic symbol table.
In general, the strategy has been that the disassembler enables a
maximal set of non-conflicting extensions, thereby doing the right thing
for the largest number of users.
This change lets me test OpenOCD's behavior when harts become available.
It only affects how things look to the debugger. Harts that are
"unavailable" still execute code as usual.
Control is implemented through the 2 LSBs of the DMCUSTOM register in
the Debug Module.
Plugins should now implement and register a device_factory_t to
configure how that device should be parsed from a FDT, and an optional
default DTS string.
This drops support for command-line flag-based device configuration
Add disassembler support for all instructions in Zvk extensions:
- Zvbb (bitmanip)
- Zvbc (carryless multiplication)
- Zvkg (GMAC)
- Zvkned (AES)
- Zvknha / Zvknhb (SHA-256, SHA-512)
- Zvksed (SM4)
- Zvksh (SM3)
Macros are used to limit code duplication, following the example
of the base V extension. Because the V extension undefines some
of its macros after their use, there Zvk support does define some
similar macros.

Implement the Zvksh sub-extension, "ShangMi Suite: SM3 Hash
Function Instructions":
- vsm3me.vv, message expansion,
- vsm3c.vi, compression rounds.
This also introduces a SM3 specific header for common logic.

Implement the instructions part of the Zvknha and Zvknhb
sub-extensions:
- vsha2ms.vv, message schedule
- vsha2ch.vv / vsha2cl.vv, compression rounds
A header files for common macros is added.

Implement the proposed instruction in Zvkg, vghmac.vv,
Vector Carryless Multiply Accumulate over GHASH Galois-Field.
The instruction performs one step of GHASH routine as described
in "NIST Special Publication 800-38D" a.k.a the AES-GCM specification.
The logic was written to closely track the pseudo-code
in the Zvk specification.
