//! Example usage:

//! ./gen_stubs /path/to/musl/build-all >libc.S
|
|
//!
|
|
//! The directory 'build-all' is expected to contain these subdirectories:
|
|
//! arm x86 mips mips64 powerpc powerpc64 riscv64 x86_64
|
|
//!
|
|
//! ...each with 'lib/libc.so' inside of them.
|
|
//!
|
|
//! When building the resulting libc.S file, these defines are required:
|
|
//! * `-DPTR64`: when the architecture is 64-bit
|
|
//! * One of the following, corresponding to the CPU architecture:
|
|
//! - `-DARCH_riscv64`
|
|
//! - `-DARCH_mips`
|
|
//! - `-DARCH_mips64`
|

//! - `-DARCH_i386`
|

//! - `-DARCH_x86_64`
|

//! - `-DARCH_aarch64`

|
// TODO: pick the best index to put them into instead of at the end
|
|
// - e.g. find a common previous symbol and put it after that one
|
