From fbb64aa69835c8e3e9efe0afc8a73058b5a0fb3c Mon Sep 17 00:00:00 2001 From: Yonghong Song Date: Tue, 17 Dec 2019 16:24:23 -0800 Subject: [PATCH] [BPF] extend BTF_KIND_FUNC to cover global, static and extern funcs Previously extern function is added as BTF_KIND_VAR. This does not work well with existing BTF infrastructure as function expected to use BTF_KIND_FUNC and BTF_KIND_FUNC_PROTO. This patch added extern function to BTF_KIND_FUNC. The two bits 0:1 of btf_type.info are used to indicate what kind of function it is: 0: static 1: global 2: extern Differential Revision: https://reviews.llvm.org/D71638 --- llvm/lib/Target/BPF/BTF.h | 7 ++ llvm/lib/Target/BPF/BTFDebug.cpp | 55 +++++++------ llvm/lib/Target/BPF/BTFDebug.h | 6 +- llvm/test/CodeGen/BPF/BTF/binary-format.ll | 4 +- llvm/test/CodeGen/BPF/BTF/extern-builtin.ll | 89 ++++++++++++++++++++ llvm/test/CodeGen/BPF/BTF/extern-func-arg.ll | 79 ++++++++++++++++++ llvm/test/CodeGen/BPF/BTF/extern-global-var.ll | 2 +- .../BPF/BTF/extern-var-func-weak-section.ll | 21 ++--- llvm/test/CodeGen/BPF/BTF/extern-var-func-weak.ll | 21 ++--- llvm/test/CodeGen/BPF/BTF/extern-var-func.ll | 21 ++--- llvm/test/CodeGen/BPF/BTF/extern-var-section.ll | 38 ++++----- .../test/CodeGen/BPF/BTF/extern-var-struct-weak.ll | 2 +- llvm/test/CodeGen/BPF/BTF/extern-var-struct.ll | 2 +- .../CodeGen/BPF/BTF/extern-var-weak-section.ll | 38 ++++----- llvm/test/CodeGen/BPF/BTF/filename.ll | 2 +- llvm/test/CodeGen/BPF/BTF/func-func-ptr.ll | 2 +- llvm/test/CodeGen/BPF/BTF/func-non-void.ll | 2 +- llvm/test/CodeGen/BPF/BTF/func-source.ll | 2 +- llvm/test/CodeGen/BPF/BTF/func-typedef.ll | 2 +- llvm/test/CodeGen/BPF/BTF/func-unused-arg.ll | 2 +- llvm/test/CodeGen/BPF/BTF/func-void.ll | 2 +- llvm/test/CodeGen/BPF/BTF/local-var.ll | 2 +- llvm/test/CodeGen/BPF/BTF/static-func.ll | 96 ++++++++++++++++++++++ .../CodeGen/BPF/BTF/static-var-derived-type.ll | 2 +- llvm/test/CodeGen/BPF/BTF/static-var-inited-sec.ll | 2 +- llvm/test/CodeGen/BPF/BTF/static-var-inited.ll | 2 +- .../CodeGen/BPF/BTF/static-var-readonly-sec.ll | 2 +- llvm/test/CodeGen/BPF/BTF/static-var-readonly.ll | 2 +- llvm/test/CodeGen/BPF/BTF/static-var-sec.ll | 2 +- .../CodeGen/BPF/BTF/static-var-zerolen-array.ll | 2 +- llvm/test/CodeGen/BPF/BTF/static-var.ll | 2 +- llvm/test/CodeGen/BPF/CORE/offset-reloc-basic.ll | 2 +- .../CodeGen/BPF/CORE/offset-reloc-multilevel.ll | 2 +- .../BPF/CORE/offset-reloc-struct-anonymous.ll | 2 +- .../CodeGen/BPF/CORE/offset-reloc-struct-array.ll | 2 +- llvm/test/CodeGen/BPF/CORE/offset-reloc-union.ll | 2 +- 36 files changed, 381 insertions(+), 142 deletions(-) create mode 100644 llvm/test/CodeGen/BPF/BTF/extern-builtin.ll create mode 100644 llvm/test/CodeGen/BPF/BTF/extern-func-arg.ll create mode 100644 llvm/test/CodeGen/BPF/BTF/static-func.ll diff --git a/llvm/lib/Target/BPF/BTF.h b/llvm/lib/Target/BPF/BTF.h index ee06176..ad3dcc1 100644 --- a/llvm/lib/Target/BPF/BTF.h +++ b/llvm/lib/Target/BPF/BTF.h @@ -176,6 +176,13 @@ struct BTFParam { uint32_t Type; }; +/// BTF_KIND_FUNC can be global, static or extern. +enum : uint8_t { + FUNC_STATIC = 0, + FUNC_GLOBAL = 1, + FUNC_EXTERN = 2, +}; + /// Variable scoping information. enum : uint8_t { VAR_STATIC = 0, ///< Linkage: InternalLinkage diff --git a/llvm/lib/Target/BPF/BTFDebug.cpp b/llvm/lib/Target/BPF/BTFDebug.cpp index 86e625b..a9fb04f 100644 --- a/llvm/lib/Target/BPF/BTFDebug.cpp +++ b/llvm/lib/Target/BPF/BTFDebug.cpp @@ -308,10 +308,11 @@ void BTFTypeFuncProto::emitType(MCStreamer &OS) { } } -BTFTypeFunc::BTFTypeFunc(StringRef FuncName, uint32_t ProtoTypeId) +BTFTypeFunc::BTFTypeFunc(StringRef FuncName, uint32_t ProtoTypeId, + uint32_t Scope) : Name(FuncName) { Kind = BTF::BTF_KIND_FUNC; - BTFType.Info = Kind << 24; + BTFType.Info = (Kind << 24) | Scope; BTFType.Type = ProtoTypeId; } @@ -897,8 +898,9 @@ void BTFDebug::beginFunctionImpl(const MachineFunction *MF) { visitSubroutineType(SP->getType(), true, FuncArgNames, ProtoTypeId); // Construct subprogram func type + uint8_t Scope = SP->isLocalToUnit() ?
