From 4b63d2ae1dd1cedbb0b2a61fa0da9559043dfabb Mon Sep 17 00:00:00 2001 From: Jim Grosbach Date: Fri, 18 May 2012 19:12:01 +0000 Subject: Refactor data-in-code annotations. Use a dedicated MachO load command to annotate data-in-code regions. This is the same format the linker produces for final executable images, allowing consistency of representation and use of introspection tools for both object and executable files. Data-in-code regions are annotated via ".data_region"/".end_data_region" directive pairs, with an optional region type. data_region_directive := ".data_region" { region_type } region_type := "jt8" | "jt16" | "jt32" | "jta32" end_data_region_directive := ".end_data_region" The previous handling of ARM-style "$d.*" labels was broken and has been removed. Specifically, it didn't handle ARM vs. Thumb mode when marking the end of the section. rdar://11459456 llvm-svn: 157062 --- llvm/test/CodeGen/ARM/data-in-code-annotations.ll | 42 +++++++++++++++++++++++ 1 file changed, 42 insertions(+) create mode 100644 llvm/test/CodeGen/ARM/data-in-code-annotations.ll (limited to 'llvm/test/CodeGen/ARM/data-in-code-annotations.ll') diff --git a/llvm/test/CodeGen/ARM/data-in-code-annotations.ll b/llvm/test/CodeGen/ARM/data-in-code-annotations.ll new file mode 100644 index 00000000000..a66a9d1292f --- /dev/null +++ b/llvm/test/CodeGen/ARM/data-in-code-annotations.ll @@ -0,0 +1,42 @@ +; RUN: llc < %s -mtriple=armv7-apple-darwin | FileCheck %s + +define double @f1() nounwind { +; CHECK: f1: +; CHECK: .data_region +; CHECK: .long 1413754129 +; CHECK: .long 1074340347 +; CHECK: .end_data_region + ret double 0x400921FB54442D11 +} + + +define i32 @f2() { +; CHECK: f2: +; CHECK: .data_region jt32 +; CHECK: .end_data_region + +entry: + switch i32 undef, label %return [ + i32 1, label %sw.bb + i32 2, label %sw.bb6 + i32 3, label %sw.bb13 + i32 4, label %sw.bb20 + ] + +sw.bb: ; preds = %entry + br label %return + +sw.bb6: ; preds = %entry + br label %return + +sw.bb13: ; preds = %entry + br label %return + +sw.bb20: ; preds = %entry + %div = sdiv i32 undef, undef + br label %return + +return: ; preds = %sw.bb20, %sw.bb13, %sw.bb6, %sw.bb, %entry + %retval.0 = phi i32 [ %div, %sw.bb20 ], [ undef, %sw.bb13 ], [ undef, %sw.bb6 ], [ undef, %sw.bb ], [ 0, %entry ] + ret i32 %retval.0 +} -- cgit v1.2.3
