CGEN is cool, but the BPF architecture is simply too bizarre for it.
The weird way of BPF to handle endianness in instruction encoding, the
weird C-like alternative assembly syntax, the weird abuse of
multi-byte (or infra-byte) instruction fields as opcodes, the unusual
presence of opcodes beyond the first 32-bits of some instructions, are
all examples of what makes it a PITA to continue using CGEN for this
port. The bpf.cpu file is becoming so complex and so nested with
p-macros that it is very difficult to read, and quite challenging to
update. Also, every time we are forced to change something in CGEN to
accommodate BPF requirements (which is often) we have to do extensive
testing to make sure we do not break any other target using CGEN.
This is getting un-maintenable.
So I have decided to bite the bullet and revamp/rewrite the port so it
no longer uses CGEN. Overall, this involved:
* To remove the cpu/bpf.{cpu,opc} descriptions.
* To remove the CGEN generated files.
* To replace the CGEN generated opcodes table with a new hand-written
opcodes table for BPF.
* To replace the CGEN generated disassembler wih a new disassembler
that uses the new opcodes.
* To replace the CGEN generated assembler with a new assembler that uses the
new opcodes.
* To replace the CGEN generated simulator with a new simulator that uses the
new opcodes. [This is pushed in GDB in another patch.]
* To adapt the build systems to the new situation.
Additionally, this patch introduces some extensions and improvements:
* A new BPF relocation BPF_RELOC_BPF_DISP16 plus corresponding ELF
relocation R_BPF_GNU_64_16 are added to the BPF BFD port. These
relocations are used for section-relative 16-bit offsets used in
load/store instructions.
* The disassembler now has support for the "pseudo-c" assembly syntax of
BPF. What dialect to use when disassembling is controlled by a command
line option.
* The disassembler now has support for dumping instruction immediates in
either octal, hexadecimal or decimal. The used output base is controlled
by a new command-line option.
* The GAS BPF test suite has been re-structured and expanded in order to
test the disassembler pseudoc syntax support. Minor bugs have been also
fixed there. The assembler generic tests that were disabled for bpf-*-*
targets due to the previous implementation of pseudoc syntax are now
re-enabled. Additional tests have been added to test the new features of
the assembler. .dump files are no longer used.
* The linker BPF test suite has been adapted to the command line options
used by the new disassembler.
The result is very satisfactory. This patchs adds 3448 lines of code
and removes 10542 lines of code.
Tested in:
* Target bpf-unknown-none with 64-bit little-endian host and 32-bit
little-endian host.
* Target x86-64-linux-gnu with --enable-targets=all
Note that I have not tested in a big-endian host yet. I will do so
once this lands upstream so I can use the GCC compiler farm.
I have not included ChangeLog entries in this patch: these would be
massive and not very useful, considering this is pretty much a rewrite
of the port. I beg the indulgence of the global maintainers.

-
-;;;; The ISAs
-
-;; Logically, eBPF comforms a single instruction set featuring two
-;; kind of instructions: 64-bit instructions and 128-bit instructions.
-;;
-;; The 64-bit instructions have the form:
-;;
-;; code:8 regs:8 offset:16 imm:32
-;;
-;; Whereas the 128-bit instructions (at the moment there is only one
-;; of such instructions, lddw) have the form:
-;;
-;; code:8 regs:8 offset:16 imm:32 unused:32 imm:32
-;;
-;; In both formats `regs' is itself composed by two fields:
-;;
-;; dst:4 src:4
-;;
-;; The ISA is supposed to be orthogonal to endianness: the endianness
-;; of the instruction fields follow the endianness of the host running
-;; the eBPF program, and that's all. However, this is not entirely
-;; true. The definition of an eBPF code in the Linux kernel is:
-;;
-;; struct bpf_insn {
-;; __u8 code; /* opcode */
-;; __u8 dst_reg:4; /* dest register */
-;; __u8 src_reg:4; /* source register */
-;; __s16 off; /* signed offset */
-;; __s32 imm; /* signed immediate constant */
-;; };
-;;
-;; Since the ordering of fields in C bitmaps is defined by the
-;; implementation, the impact of endianness in the encoding of eBPF
-;; instructions is effectively defined by GCC. In particular, GCC
-;; places dst_reg before src_reg in little-endian code, and the other
-;; way around in big-endian code.
-;;
-;; So, in reality, eBPF comprises two instruction sets: one for
-;; little-endian with instructions like:
-;;
-;; code:8 src:4 dst:4 offset:16 imm:32 [unused:32 imm:32]
-;;
-;; and another for big-endian with instructions like:
-;;
-;; code:8 dst:4 src:4 offset:16 imm:32 [unused:32 imm:32]
-;;
-;; where `offset' and the immediate fields are encoded in
-;; little-endian and big-endian byte-order, respectively.

- The parser represent a FSM for the grammar described above. So for example
- the following rule:
-
- ` bpf_alu_insn : BPF_REG bpf_alu_operator register_or_imm32'
-
- Is parser as follows:
-
- 1. It starts in state 0.
+/* Assemble a machine instruction in STR and emit the frags/bytes it
+ assembles to. */
- 2. Consumes next token, e.g: `BPF_REG' and set `state' variable to a
- particular state to helps to identify, in this case, that a register
- token has been read, a comment surrounded by a single quote in the
- pseudo-c token is added along with the new `state' value to indicate
- what the scanner has read, e.g.:
-
- state = 6; // dst_reg = str_cast ( 'src_reg'
-
- So, in `state 6' the scanner has consumed: a destination register
- (BPF_REG), an equal character (BPF_MOV), a cast token (BPF_CAST), an
- open parenthesis (BPF_CHR_OPEN_BR) and the source register (BPF_REG).
-
- 3. If the accumulated tokens represent a complete BPF pseudo-c syntax
- instruction then, a validation of the terms is made, for example: if
- the registers have the same sizes (32/64 bits), if a specific
- destination register must be used, etc., after that, a builder:
- build_bfp_{non_generic_load,atomic_insn,jmp_insn,arithm_insn,endianness,load_store_insn}
- is invoked, internally, it translates the BPF pseudo-c instruction to
- a BPF GAS instruction using the previous terms recollected by the
- scanner.
-
- 4. If a successful build of BPF GAS instruction was done, a final
- state is set to `ST_EOI' (End Of Instruction) meaning that is not
- expecting for more tokens in such instruction. Otherwise if the
- conditions to calling builder are not satisfied an error is emitted
- and `parse_err' is set.

The eBPF processor provides ten general-purpose 64-bit registers,
which are read-write, and a read-only frame pointer register:
+@noindent
+In normal syntax:
+
@table @samp
@item %r0 .. %r9
General-purpose registers.
@item %r10
-Frame pointer register.
+@itemx %fp
+Read-only frame pointer register.
@end table
-Some registers have additional names, to reflect their role in the
-eBPF ABI:
+All BPF registers are 64-bit long. However, in the Pseudo-C syntax
+registers can be referred using different names, which actually
+reflect the kind of instruction they appear on:
+
+@noindent
+In pseudoc syntax:
@table @samp
-@item %a
-This is @samp{%r0}.
-@item %ctx
-This is @samp{%r6}.
-@item %fp
-This is @samp{%r10}.
+@item r0..r9

-
-For example, to load the address of the pseudo map with file

-
-@smallexample

-@subsubsection Atomic instructions
+@subsection 32-bit jump instructions
-Atomic exchange-and-add instructions are provided in two flavors: one
-for swapping 64-bit quantities and another for 32-bit quantities.
+eBPF provides the following compare-and-jump instructions, which
+compare the 32-bit values of the two given registers, or the values of
+a register and an immediate, and perform a branch in case the
+comparison holds true.
-@table @code
-@item xadddw [%d+offset16],%s
-Exchange-and-add a 64-bit value at the specified location.
-@item xaddw [%d+offset16],%s
-Exchange-and-add a 32-bit value at the specified location.
-@end table
+These instructions are only available in BPF v3 or later.
-@node BPF Pseudo-C Syntax
-@section BPF Pseudo-C Syntax
+@table @code
+@item jeq32 rd, rs, disp16
+@itemx jeq32 rd, imm32, disp16
+@itemx if rd == rs goto disp16
+@itemx if rd == imm32 goto disp16
+Jump if equal, unsigned.
-This assembler supports another syntax to denote BPF instructions,
-which is an alternative to the normal looking syntax documented above.
-This alternatative syntax, which we call @dfn{pseudo-C syntax}, is
-supported by the LLVM/clang integrated assembler.
+@item jgt32 rd, rs, disp16
+@itemx jgt32 rd, imm32, disp16
+@itemx if rd > rs goto disp16
+@itemx if rd > imm32 goto disp16
+Jump if greater, unsigned.
-This syntax is very unconventional, but we need to support it in order
-to support inline assembly in existing BPF programs.
+@item jge32 rd, rs, disp16
+@itemx jge32 rd, imm32, disp16
+@itemx if rd >= rs goto disp16
+@itemx if rd >= imm32 goto disp16
+Jump if greater or equal.
-Note that the assembler is able to parse sources in which both
-syntaxes coexist: some instructions can use the usual assembly like
-syntax, whereas some other instructions in the same file can use the
-pseudo-C syntax.
+@item jlt32 rd, rs, disp16
+@itemx jlt32 rd, imm32, disp16

+@itemx jle32 rd, imm32, disp16
+@itemx if rd <= rs goto disp16
+@itemx if rd <= imm32 goto disp16
+Jump if lesser or equal.
-All BPF registers are 64-bit long. However, in the Pseudo-C syntax
-registers can be referred using different names, which actually
-reflect the kind of instruction they appear on:
+@item jset32 rd, rs, disp16
+@itemx jset32 rd, imm32, disp16
+@itemx if rd & rs goto disp16
+@itemx if rd & imm32 goto disp16
+Jump if signed equal.
-@table @samp
-@item r0..r9
-General-purpose register in an instruction that operates on its value

-In all the instructions below, the operations are 64-bit or 32-bit
-depending on the names used to refer to the registers. For example
-@code{r3 += r2} will perform 64-bit addition, whereas @code{w3 += w2}

-for example @code{r3 += w2}.
