From f1b0e05b3d5728d54b664885ef91a555d632be4c Mon Sep 17 00:00:00 2001 From: David Mak Date: Wed, 6 Sep 2023 14:02:06 +0800 Subject: [PATCH] core: Rename IR variables Because it is unclear which variables are expressions and subexpressions, all variables which are previously anonymous are named using (1) the control flow statement if available, (2) the possible name of the variable as inferred from the variable name in Rust, and (3) the "addr" prefix to indicate that the values are pointers. These three strings are joint together using '.', forming "for.i.addr" for instance. --- nac3artiq/src/codegen.rs | 8 ++++---- nac3core/src/codegen/expr.rs | 6 +++--- nac3core/src/codegen/stmt.rs | 12 ++++++------ 3 files changed, 13 insertions(+), 13 deletions(-) diff --git a/nac3artiq/src/codegen.rs b/nac3artiq/src/codegen.rs index 94563bab..cbadad49 100644 --- a/nac3artiq/src/codegen.rs +++ b/nac3artiq/src/codegen.rs @@ -84,7 +84,7 @@ impl<'b> CodeGenerator for ArtiqCodeGenerator<'b> { .try_as_basic_value() .left() .unwrap();
