From 7a85ad151daece3d0bba3c8d23081502a0956c95 Mon Sep 17 00:00:00 2001 From: mlugg Date: Sat, 19 Aug 2023 02:35:00 +0100 Subject: cbe: elide block result allocation for 0-bit types This logic already existed for the void type, but is also necessary for other 0-bit types. Without it, we try to alloc a local for a 0-bit type which gets translated to a local of type `void` which C doesn't like. --- src/codegen/c.zig | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/codegen') diff --git a/src/codegen/c.zig b/src/codegen/c.zig index bea3c02985..330a9b33e8 100644 --- a/src/codegen/c.zig +++ b/src/codegen/c.zig @@ -4285,7 +4285,7 @@ fn airBlock(f: *Function, inst: Air.Inst.Index) !CValue { const writer = f.object.writer(); const inst_ty = f.typeOfIndex(inst); - const result = if (inst_ty.ip_index != .void_type and !f.liveness.isUnused(inst)) + const result = if (inst_ty.hasRuntimeBitsIgnoreComptime(mod) and !f.liveness.isUnused(inst)) try f.allocLocal(inst, inst_ty) else .none; -- cgit v1.2.3
