Processors with support for compact branch instructions & methods

After a compiler inserts a branch instruction into an object file 309, it examines the next instruction to be inserted 314. If that instruction is allowed after a branch, it is inserted 316. If it is not allowed, the compiler attempts to identify a different instruction, which may be inserted 320. I...

Summary:After a compiler inserts a branch instruction into an object file 309, it examines the next instruction to be inserted 314. If that instruction is allowed after a branch, it is inserted 316. If it is not allowed, the compiler attempts to identify a different instruction, which may be inserted 320. If such an instruction is identified it is inserted 325. Otherwise, the compiler determines whether the target architecture supports generating exceptions when a forbidden instruction is detected after a branch 322. If exceptions are supported, the original instruction is inserted 328. Otherwise a no-op instruction is inserted 318. The compiler may be a high level language pre-execution compiler or a byte code just in time compiler.
