From 6ff46266d1071e3330506470ab91f4d6873ac0a4 Mon Sep 17 00:00:00 2001 From: Craig Topper Date: Sun, 17 Apr 2016 17:37:33 +0000 Subject: [PATCH] Declare MVT::SimpleValueType as an int8_t sized enum. This removes 400 bytes from TargetLoweringBase and probably other places. This required changing several places to print VT enums as strings instead of raw ints since the proper method to use to print became ambiguous. This is probably an improvement anyway. This also appears to save ~8K from an x86 self host build of llc. llvm-svn: 266562 --- llvm/include/llvm/CodeGen/MachineValueType.h | 18 +++++++++--------- llvm/include/llvm/CodeGen/ValueTypes.td | 16 ++++++++-------- llvm/lib/Target/BPF/BPFISelLowering.cpp | 2 +- llvm/lib/Target/MSP430/MSP430ISelLowering.cpp | 2 +- llvm/lib/Target/XCore/XCoreISelLowering.cpp | 2 +- llvm/test/TableGen/intrinsic-long-name.td | 2 +- llvm/utils/TableGen/DAGISelMatcher.cpp | 8 +++++--- 7 files changed, 26 insertions(+), 24 deletions(-) diff --git a/llvm/include/llvm/CodeGen/MachineValueType.h b/llvm/include/llvm/CodeGen/MachineValueType.h index 8cfd5fe2b608..0bb53d1a5374 100644 --- a/llvm/include/llvm/CodeGen/MachineValueType.h +++ b/llvm/include/llvm/CodeGen/MachineValueType.h @@ -28,7 +28,7 @@ namespace llvm { /// type can be represented by an MVT. class MVT { public: - enum SimpleValueType { + enum SimpleValueType : int8_t { // INVALID_SIMPLE_VALUE_TYPE - Simple value types less than zero are // considered extended value types.
