From a10fd6d3d1027b3903d27af701f876e36c1725c0 Mon Sep 17 00:00:00 2001 From: Jakob Stoklund Olesen Date: Tue, 2 Apr 2013 04:09:06 +0000 Subject: [PATCH] Add predicates for distinguishing 32-bit and 64-bit modes. The 'sparc' architecture produces 32-bit code while 'sparcv9' produces 64-bit code. It is also possible to run 32-bit code using SPARC v9 instructions with: llc -march=sparc -mattr=+v9 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178524 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/Sparc/SparcInstrInfo.td | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/lib/Target/Sparc/SparcInstrInfo.td b/lib/Target/Sparc/SparcInstrInfo.td index 3a5200d48d3..1c1bb9826cb 100644 --- a/lib/Target/Sparc/SparcInstrInfo.td +++ b/lib/Target/Sparc/SparcInstrInfo.td @@ -21,6 +21,12 @@ include "SparcInstrFormats.td" // Feature predicates. //===----------------------------------------------------------------------===// +// True when generating 32-bit code. +def Is32Bit : Predicate<"!Subtarget.is64Bit()">; + +// True when generating 64-bit code.
