Enum solana_rbpf::program::SBPFVersion

pub enum SBPFVersion {
    V1,
    V2,
    V3,
}

Defines a set of sbpf_version of an executable

Variants

V1

The legacy format

V2

The current format

V3

The future format with BTF support

Implementations

impl SBPFVersion

pub fn enable_le(&self) -> bool

Enable the little-endian byte swap instructions

pub fn enable_neg(&self) -> bool

Enable the negation instruction

pub fn swap_sub_reg_imm_operands(&self) -> bool

Swaps the reg and imm operands of the subtraction instruction

pub fn disable_lddw(&self) -> bool

Disable the only two slots long instruction: LD_DW_IMM

pub fn enable_pqr(&self) -> bool

Enable the BPF_PQR instruction class

pub fn callx_uses_src_reg(&self) -> bool

Use src reg instead of imm in callx

pub fn reject_rodata_stack_overlap(&self) -> bool

Ensure that rodata sections don’t exceed their maximum allowed size and overlap with the stack

pub fn enable_elf_vaddr(&self) -> bool

Allow sh_addr != sh_offset in elf sections. Used in V2 to align section vaddrs to MM_PROGRAM_START.

pub fn dynamic_stack_frames(&self) -> bool

Use dynamic stack frame sizes

pub fn static_syscalls(&self) -> bool

Support syscalls via pseudo calls (insn.src = 0)

Trait Implementations

impl Clone for SBPFVersion

fn clone(&self) -> SBPFVersion

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SBPFVersion

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for SBPFVersion

fn eq(&self, other: &SBPFVersion) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
