URL: https://github.com/llvm/llvm-project/commit/a6fa21c5aabb9e7d47c221aa8403d96cb154d549 DIFF: https://github.com/llvm/llvm-project/commit/a6fa21c5aabb9e7d47c221aa8403d96cb154d549.diff LOG: [CIR] Upstream basic CodeGen tests from incubator (#183998) This PR upstreams `expressions.cpp` and `c89-implicit-int.c` from the ClangIR incubator to the mainline. Following the incremental approach discussed in #156747 and the feedback from the closed PR #157333, I have: 1. Copied the files directly from the incubator to preserve history. 2. Updated the `RUN` lines to use the `--check-prefix=CIR` flag. 3. Converted `CHECK:` lines to `CIR:`. 4. Standardized variable captures using the `%[[VAR:.*]]` regex syntax (in `expressions.cpp`). Verified locally with `llvm-lit`. This is a partial fix for #156747. *Note: As suggested in previous reviews, I am focusing only on the `CIR` checks for now to keep the upstreaming incremental. OGCG/LLVM verification can be added in a follow-up PR once the base tests land.* Added: clang/test/CIR/CodeGen/c89-implicit-int.c clang/test/CIR/CodeGen/expressions.cpp Modified: Removed: ################################################################################ diff --git a/clang/test/CIR/CodeGen/c89-implicit-int.c b/clang/test/CIR/CodeGen/c89-implicit-int.c new file mode 100644 index 0000000000000..f7e6153cbfbf2 --- /dev/null +++ b/clang/test/CIR/CodeGen/c89-implicit-int.c @@ -0,0 +1,11 @@ +// RUN: %clang_cc1 -triple x86_64-unknown-linux-gnu -std=c89 -emit-cir %s -o %t.cir +// RUN: FileCheck --input-file=%t.cir %s --check-prefix=CIR + +// Implicit int return type. +test = 0; +func (void) { + return 0; +} + +// CIR: cir.global external @test = #cir.int<0> : !s32i +// CIR: cir.func {{.*}} @func() -> !s32i diff --git a/clang/test/CIR/CodeGen/expressions.cpp b/clang/test/CIR/CodeGen/expressions.cpp new file mode 100644 index 0000000000000..50bffbfb68739 --- /dev/null +++ b/clang/test/CIR/CodeGen/expressions.cpp @@ -0,0 +1,11 @@ +// RUN: %clang_cc1 -std=c++17 -triple x86_64-unknown-linux-gnu -fclangir -emit-cir %s -o %t.cir +// RUN: FileCheck --input-file=%t.cir %s --check-prefix=CIR + +void test(int a) { + // Should generate LValue parenthesis expression. + (a) = 1; +} + +// CIR: cir.func {{.*}} @{{.+}}test +// CIR: %[[CONST:.*]] = cir.const #cir.int<1> : !s32i +// CIR: cir.store{{.*}} %[[CONST]], %{{.+}} : !s32i, !cir.ptr<!s32i> _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
