From 957da9056c36a5eea15c6058701f7465b31f64a8 Mon Sep 17 00:00:00 2001 From: Kimplul Date: Sun, 30 Mar 2025 22:36:53 +0300 Subject: WIP: rewrite C++ backend to be C + C allows for a bit more control, and we can manually handle closure contexts. For example `examples/fib.fwd` now works for effectively any `n`, pretty cool. + Fairly slow Fibonacci, I must admit. Initial profiling indicates it's mainly due to branch mispredictions, but I'll have to look into this a bit deeper. + The code is a bit hacked together, for now I'm more interested in getting things working, I'll worry about making things pretty later. + For testing, there's also initial support for modules, just so I can print stuff to the terminal + This commit is way too big, lol --- examples/sum.fwd | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) create mode 100644 examples/sum.fwd (limited to 'examples/sum.fwd') diff --git a/examples/sum.fwd b/examples/sum.fwd new file mode 100644 index 0000000..89a2d11 --- /dev/null +++ b/examples/sum.fwd @@ -0,0 +1,23 @@ +print_int(i64 a); +print_nl(); + +sum_inner(i64 s, i64 n, (i64) res) +{ + if n <= 0 { + res(s); + } else { + sum_inner(s + n, n - 1, res); + } +} + +sum(i64 n, (i64) res) +{ + sum_inner(0, n, res); +} + +main() +{ + sum(1000000000) => i64 s; + print_int(s); + print_nl(); +} -- cgit v1.2.3
