From 6186de5c54b580414b2d162e0f335b62b3d9812c Mon Sep 17 00:00:00 2001 From: Bradley Smith Date: Fri, 1 Nov 2013 13:27:35 +0000 Subject: [ARM] Add Virtualization subtarget feature and more build attributes in this area Add a Virtualization ARM subtarget feature along with adding proper build attribute emission for Tag_Virtualization_use (encodes Virtualization and TrustZone) and Tag_MPextension_use. Also rework test/CodeGen/ARM/2010-10-19-mc-elf-objheader.ll testcase to something that is more maintainable. This changes the focus of this testcase away from testing CPU defaults (which is tested elsewhere), onto specifically testing that attributes are encoded correctly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193859 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/ARM/ARMSubtarget.h | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'lib/Target/ARM/ARMSubtarget.h') diff --git a/lib/Target/ARM/ARMSubtarget.h b/lib/Target/ARM/ARMSubtarget.h index 41aa2adbbc..0eb0a4463e 100644 --- a/lib/Target/ARM/ARMSubtarget.h +++ b/lib/Target/ARM/ARMSubtarget.h @@ -150,6 +150,10 @@ protected: /// extension (ARMv7 only). bool HasMPExtension; + /// HasVirtualization - True if the subtarget supports the Virtualization + /// extension. + bool HasVirtualization; + /// FPOnlySP - If true, the floating point unit only supports single /// precision. bool FPOnlySP; @@ -260,6 +264,7 @@ public: bool hasNEON() const { return HasNEON; } bool hasCrypto() const { return HasCrypto; } bool hasCRC() const { return HasCRC; } + bool hasVirtualization() const { return HasVirtualization; } bool useNEONForSinglePrecisionFP() const { return hasNEON() && UseNEONForSinglePrecisionFP; } -- cgit v1.2.3
