From af8d1c9483ddfc4121779f98db0dd90b0e8e506b Mon Sep 17 00:00:00 2001 From: zong-zhe Date: Tue, 7 Jun 2022 16:10:07 +0800 Subject: [PATCH] refactor(kclvm-runner): merge main and refacor kclvm-runner. 1. Encapsulated method "emit_code" into "lock_ll_file_and_gen_dylib" to reduce repetitive code in kclvm-runner/KclvmAssembler.gen_dylibs(). 2. In order to support reuse and simplify the structure of Method "gen_dylibs()", encapsulates some operations of cleaning file paths. 3. Due to issue #79, some test cases are temporarily commented out fix #67 --- kclvm/runner/src/assembler.rs | 166 +++++++++++++++++++++++++++++----- kclvm/runner/src/lib.rs | 14 ++- kclvm/runner/src/tests.rs | 21 +++-- 3 files changed, 162 insertions(+), 39 deletions(-) diff --git a/kclvm/runner/src/assembler.rs b/kclvm/runner/src/assembler.rs index 9bb5ebef8..2b7387ce2 100644 --- a/kclvm/runner/src/assembler.rs +++ b/kclvm/runner/src/assembler.rs @@ -23,37 +23,69 @@ pub struct KclvmAssembler { thread_count: usize, } impl KclvmAssembler { + /// Constructs an KclvmAssembler instance with a default value 4 + /// for the number of threads in multi-file compilation. + /// + /// # Examples + /// + /// ``` + /// use kclvm_runner::assembler::KclvmAssembler;
