Re: [TCLCORE] TIP 720: Updated Tcl Bytecode Opcodes CFV (NOTE: NO DELAY)

[<apn...@ya...>]

TIP #720: YES

 

A final note, using the tcltest and tcltests packages as a sample, there is
roughly 60% increase in bytecode size. That is acceptable in my view as
bytecode is a small component in memory usage.

 

TIP 720

Number of procs: 200

Code size: 88280

As promised, I've done a TIP for the updates to the bytecode compiler. It's
largely there to document the notable features of a substantial changeset.

 

https://core.tcl-lang.org/tips/doc/trunk/tip/720.md

 

It covers the essentials; of particular note is that no true public API is
affected. That said, tcl::unsupported::assemble is affected, but via
enhancement (it gets new opcodes), and tdkcompiler/tbcload will definitely
need more work due to the new auxiliary structure type (for a numeric jump
table).

 

Given the lack of public surface changes - if you're not messing with
compilation guts, you shouldn't need to care - I'm going to call a vote on
this TIP immediately.

TIP 720: YES
