MoarVM is the Rakudo compiler's virtual machine for the Raku Programming Language.

Installation

`+jit`	Enable Just-In-Time-Compiler. Has no effect except on AMD64 and Darwin.
`asan`	Enable clang's Address Sanitizer functionality. Expect longer compile time.
`clang`	Use clang compiler instead of GCC
`debug`	Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces
`doc`	Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
`optimize`	Enable optimization via CFLAGS
`static-libs`	Build static versions of dynamic libraries as well
`ubsan`	Enable clang's Undefined Behavior Sanitizer functionality. Expect longer compile time.

MVM_JIT_DISABLE (bool) Disables the just-in-time compiler. JIT compilation is enabled by default.
MVM_SPESH_DISABLE (bool) Disables the runtime bytecode optimizer. This optimization is enabled by default.
MVM_SPESH_INLINE_DISABLE (bool) Disables inlining of call frames by the bytecode optimizer. This optimization is enabled by default.
MVM_SPESH_OSR_DISABLE (bool) Disables the on-stack replacement of bytecode by the optimizer. This optimization is enabled by default.
MVM_CROSS_THREAD_WRITE_LOG (bool) Produce warnings when a thread does a write to an object it didn't allocate and doesn't have a lock for.
MVM_CROSS_THREAD_WRITE_LOG_INCLUDE_LOCKED (bool) Extend the above to include objects that are locked as well.

MoarVM is a dependency of Rakudo, the Raku compiler. As such it's not typically installed or removed on its own.
