[#68506] Seven stacks (and two questions) — Jakub Trzebiatowski <jaktrze1@...>
The Ruby Hacking Guide says that Ruby has窶ヲ seven stacks. Is it an implementation choice (and it could be implemented with one stack), or is there really a need for seven logical stacks? For example, Lua has one stack, and still closures with upvalues are totally possible (it窶冱 like Ruby窶冱 blocks that can reference local variables of their enclosing method, but it works for any function with any upvalues).

hi tony,
[ruby-core:68420] [Ruby trunk - Bug #10931] [PERF]bm_app_mandelbrot.rb 20% slower.

nobu@...

ruby-core #68420
Issue #10931 has been updated by Nobuyoshi Nakada.
On MacBook Pro late 2013, OSX 10.10.2, 2.6GHz 16GiB.
At a git-svn working directory, (`$build` is the build directory):
~~~
$ execs=; for c in `git log --since=2015/2/1 --format=%H --reverse -- complex.c`; do v=`git log -1 $c | sed '/git-svn-id:/!d;s/.*@//;s/ .*//'`; git co $c -- complex.c numeric.c && echo $'#define RUBY_REVISION '$v$'\n#define RUBY_BRANCH_NAME "bm_complex"' > revision.h && rm -f $build/{complex,numeric,version}.o && make -C $build EXEEXT=-$v mini && execs="${execs};r$v::$build/miniruby-$v"; done && ruby benchmark/driver.rb -fm -e "${execs}" -p mandel
~~~
