one small moment: when you add precompile block to previous ones, e.g.:

// RISC0
#[cfg(all(target_os = "zkvm", target_vendor = "risc0"))]
{ /* ... */ }

#[cfg(all(target_os = "zkvm", target_vendor = "zisk"))]
{ /* your code */ }

// SP1
#[cfg(all(target_os = "zkvm", target_vendor = "sp1"))]
{ /* ... */ }

can you please move your patch to the bottom, and include comment:

// RISC0
#[cfg(all(target_os = "zkvm", target_vendor = "risc0"))]
{ /* ... */ }

- #[cfg(all(target_os = "zkvm", target_vendor = "zisk"))]
- { /* your code */ }

// SP1
#[cfg(all(target_os = "zkvm", target_vendor = "sp1"))]
{ /* ... */ }

+ // Zisk
+ #[cfg(all(target_os = "zkvm", target_vendor = "zisk"))]
+ { /* your code */ }

thank you 🙏

better not to add publicly-available functions, that are zkvm-specific. If you need this function outside this file, you can make it pub(crate), to expose only to current crate.

same as previous one, should be private or pub(crate)
