From 54b8a8918bb63c98a8f58e823033232243647562 Mon Sep 17 00:00:00 2001 From: zinc Date: Wed, 14 Oct 2026 10:39:47 +0000 Subject: zc: add the defer statement defer expr; and defer { ... } register code that runs when the enclosing block ends: at the end of the block, and at return, break and continue that leave it. the tokens are kept at the defer and compiled again at each exit (block_close, body, kw_return, kw_break, kw_continue), newest first, before the block's variables are released, so the analyzer sees a deferred rt.free(p) as the transfer of p where it runs. names mean what they meant at the defer; values are read when it runs. return, break and continue inside a deferred statement are errors, reported once. works in unchecked code and closures (own base per function context). --- src/compiler/analyzer.zc | 1 + 1 file changed, 1 insertion(+) (limited to 'src/compiler/analyzer.zc') diff --git a/src/compiler/analyzer.zc b/src/compiler/analyzer.zc index 505ac09..8c63bdf 100644 --- a/src/compiler/analyzer.zc +++ b/src/compiler/analyzer.zc @@ -682,6 +682,7 @@ int local_hints(int from) { // object is an error, not a free. int block_close(int save) { int i = save, k; + defer_run(fdepth, 1); // deferred statements of this block, before its variables go af_close(save); local_hints(save); if (o3on) { -- cgit v1.2.3
