From 287f56c465806d3147e2d63c1c1c050f62db1f60 Mon Sep 17 00:00:00 2001 From: NAKAMURA Takumi Date: Wed, 16 Sep 2015 06:22:55 +0000 Subject: [PATCH] Copy back Inputs/gmlt.ll. Also DebugInfo/X86/gmlt.test uses it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@247777 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/DebugInfo/Inputs/gmlt.ll | 153 ++++++++++++++++++++++++++++++++++ 1 file changed, 153 insertions(+) create mode 100644 test/DebugInfo/Inputs/gmlt.ll diff --git a/test/DebugInfo/Inputs/gmlt.ll b/test/DebugInfo/Inputs/gmlt.ll new file mode 100644 index 00000000000..d73fef3b1de --- /dev/null +++ b/test/DebugInfo/Inputs/gmlt.ll @@ -0,0 +1,153 @@ +; REQUIRES: object-emission +; RUN: %llc_dwarf -O0 -filetype=obj < %s | llvm-dwarfdump - | FileCheck %s + +; Generated from the following source compiled with clang++ -gmlt: +; void f1() {} +; void __attribute__((section("__TEXT,__bar"))) f2() {} +; void __attribute__((always_inline)) f3() { f1(); } +; void f4() { f3(); } + +; Check that +; * -gmlt includes no DW_TAG_subprograms for subprograms without inlined +; subroutines. +; * yet still produces DW_AT_ranges and a range list in debug_ranges that +; describes those subprograms + +; CHECK: DW_TAG_compile_unit +; CHECK: DW_AT_ranges [DW_FORM_sec_offset] (0x00000000 +; CHECK-NOT: {{DW_TAG|NULL}} + +; Omitting the subprograms without inlined subroutines is not possible +; currently on Darwin as dsymutil will drop the whole CU if it has no subprograms +; (which happens with this optimization if there are no inlined subroutines). + +; DARWIN: DW_TAG_subprogram +; DARWIN-NOT: DW_TAG +; DARWIN: DW_AT_name {{.*}} "f1" +; DARWIN-NOT: {{DW_TAG|NULL}} +; DARWIN: DW_TAG_subprogram +; DARWIN-NOT: DW_TAG +; DARWIN: DW_AT_name {{.*}} "f2" +; DARWIN-NOT: {{DW_TAG|NULL}} +; DARWIN: DW_TAG_subprogram +; DARWIN-NOT: DW_TAG +; Can't check the abstract_origin value across the DARWIN/CHECK checking and +; ordering, so don't bother - just trust me, it refers to f3 down there. +; DARWIN: DW_AT_abstract_origin +; DARWIN-NOT: {{DW_TAG|NULL}} + + +; FIXME: Emitting separate abstract definitions is inefficient when we could +; just attach the DW_AT_name to the inlined_subroutine directly.
