Re: More on byte compilation

How did you generate this disassembly? By hand?
Is there a tcl command to do it?

Compile Tcl (preferably the HEAD) with the configure option --enable-
symbols=compile and then use a script like this:

proc dumpCompilations script {
set script "set ::tcl_traceCompile 2;$script"
catch { uplevel 1 $script } msg opt
set ::tcl_traceCompile 0
return -options $opt $msg
}
proc B x { ... }
dumpCompilations {
# Remember, procedures are compiled lazily...
B foo bar anything to trigger compilation
}

Note that you don't want to set tcl_traceCompile when it is compiling
interactive commands; it adds a lot to the noise. Especially if you
get bits of the [history] mechanism in there.

I'm familiar with a few assembly languages, so this
bytecode disassembly looks quite readable to me.

Thanks on the readability point; I've been working to improve it
somewhat in 8.5. :-)
