From 8030e1a0df630ec6ed1cd5ec673f6472558a4dbe Mon Sep 17 00:00:00 2001 From: Craig Topper Date: Wed, 25 Apr 2012 06:56:34 +0000 Subject: [PATCH] Add ifdef around getSubtargetFeatureName in tablegen output file so that only targets that want the function get it. This prevents other targets from getting an unused function warning. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155538 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/ARM/AsmParser/ARMAsmParser.cpp | 1 + utils/TableGen/AsmMatcherEmitter.cpp | 10 +++++++--- 2 files changed, 8 insertions(+), 3 deletions(-) diff --git a/lib/Target/ARM/AsmParser/ARMAsmParser.cpp b/lib/Target/ARM/AsmParser/ARMAsmParser.cpp index cbd9bdb77ca..3fe681f4520 100644 --- a/lib/Target/ARM/AsmParser/ARMAsmParser.cpp +++ b/lib/Target/ARM/AsmParser/ARMAsmParser.cpp @@ -7595,5 +7595,6 @@ extern "C" void LLVMInitializeARMAsmParser() { } #define GET_REGISTER_MATCHER +#define GET_SUBTARGET_FEATURE_NAME #define GET_MATCHER_IMPLEMENTATION #include "ARMGenAsmMatcher.inc" diff --git a/utils/TableGen/AsmMatcherEmitter.cpp b/utils/TableGen/AsmMatcherEmitter.cpp index 03807b10926..837516882ea 100644 --- a/utils/TableGen/AsmMatcherEmitter.cpp +++ b/utils/TableGen/AsmMatcherEmitter.cpp @@ -2395,13 +2395,17 @@ void AsmMatcherEmitter::run(raw_ostream &OS) { OS << "#endif // GET_REGISTER_MATCHER\n\n"; - - OS << "\n#ifdef GET_MATCHER_IMPLEMENTATION\n"; - OS << "#undef GET_MATCHER_IMPLEMENTATION\n\n"; + OS << "\n#ifdef GET_SUBTARGET_FEATURE_NAME\n"; + OS << "#undef GET_SUBTARGET_FEATURE_NAME\n\n"; // Generate the helper function to get the names for subtarget features. emitGetSubtargetFeatureName(Info, OS); + OS << "#endif // GET_SUBTARGET_FEATURE_NAME\n\n"; + + OS << "\n#ifdef GET_MATCHER_IMPLEMENTATION\n"; + OS << "#undef GET_MATCHER_IMPLEMENTATION\n\n"; + // Generate the function that remaps for mnemonic aliases. bool HasMnemonicAliases = emitMnemonicAliases(OS, Info); -- 2.34.1
