From 9fad4cf8036bd18040c8f350a19c3d3a1c62d0d0 Mon Sep 17 00:00:00 2001 From: Hal Finkel Date: Sun, 20 May 2012 17:11:24 +0000 Subject: [PATCH] Add a missing PPC 64-bit stwu pattern. This seems to fix the remaining compile-time failures on PPC64 when compiling with -enable-ppc-preinc. llvm-svn: 157159 --- lib/Target/PowerPC/PPCInstr64Bit.td | 8 ++++++++ test/CodeGen/PowerPC/stwu8.ll | 28 ++++++++++++++++++++++++++++ 2 files changed, 36 insertions(+) create mode 100644 test/CodeGen/PowerPC/stwu8.ll diff --git a/lib/Target/PowerPC/PPCInstr64Bit.td b/lib/Target/PowerPC/PPCInstr64Bit.td index 7f67a4159df..920fa1a3b89 100644 --- a/lib/Target/PowerPC/PPCInstr64Bit.td +++ b/lib/Target/PowerPC/PPCInstr64Bit.td @@ -660,6 +660,14 @@ def STHU8 : DForm_1a<45, (outs ptr_rc:$ea_res), (ins G8RC:$rS, iaddroff:$ptroff))]>, RegConstraint<"$ptrreg = $ea_res">, NoEncode<"$ea_res">; +def STWU8 : DForm_1a<37, (outs ptr_rc:$ea_res), (ins G8RC:$rS, + symbolLo:$ptroff, ptr_rc:$ptrreg), + "stwu $rS, $ptroff($ptrreg)", LdStStore, + [(set ptr_rc:$ea_res, + (pre_truncsti32 G8RC:$rS, ptr_rc:$ptrreg, + iaddroff:$ptroff))]>, + RegConstraint<"$ptrreg = $ea_res">, NoEncode<"$ea_res">; + def STDU : DSForm_1a<62, 1, (outs ptr_rc:$ea_res), (ins G8RC:$rS, s16immX4:$ptroff, ptr_rc:$ptrreg), "stdu $rS, $ptroff($ptrreg)", LdStSTD, diff --git a/test/CodeGen/PowerPC/stwu8.ll b/test/CodeGen/PowerPC/stwu8.ll new file mode 100644 index 00000000000..fabf7636acf --- /dev/null +++ b/test/CodeGen/PowerPC/stwu8.ll @@ -0,0 +1,28 @@ +; RUN: llc -enable-ppc-preinc < %s | FileCheck %s +target datalayout = "E-p:64:64:64-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:64:64-f32:32:32-f64:64:64-v128:128:128-n32:64" +target triple = "powerpc64-unknown-linux-gnu" + +%class.spell_checker.21.103.513.538 = type { %"class.std::map.20.102.512.537" } +%"class.std::map.20.102.512.537" = type { %"class.std::_Rb_tree.19.101.511.536" } +%"class.std::_Rb_tree.19.101.511.536" = type { %"struct.std::_Rb_tree, std::pair, int>, std::_Select1st, int>>, std::less>, std::allocator, int>> >::_Rb_tree_impl.18.100.510.535" } +%"struct.std::_Rb_tree, std::pair, int>, std::_Select1st, int>>, std::less>, std::allocator, int>> >::_Rb_tree_impl.18.100.510.535" = type { %"struct.std::less.16.98.508.533", %"struct.std::_Rb_tree_node_base.17.99.509.534", i64 } +%"struct.std::less.16.98.508.533" = type { i8 } +%"struct.std::_Rb_tree_node_base.17.99.509.534" = type { i32, %"struct.std::_Rb_tree_node_base.17.99.509.534"*, %"struct.std::_Rb_tree_node_base.17.99.509.534"*, %"struct.std::_Rb_tree_node_base.17.99.509.534"* } + +define void @test1(%class.spell_checker.21.103.513.538* %this) unnamed_addr align 2 { +entry: + %_M_header.i.i.i.i.i.i = getelementptr inbounds %class.spell_checker.21.103.513.538* %this, i64 0, i32 0, i32 0, i32 0, i32 1 + %0 = bitcast %"struct.std::_Rb_tree_node_base.17.99.509.534"* %_M_header.i.i.i.i.i.i to i8* + call void @llvm.memset.p0i8.i64(i8* %0, i8 0, i64 40, i32 4, i1 false) nounwind + store %"struct.std::_Rb_tree_node_base.17.99.509.534"* %_M_header.i.i.i.i.i.i, %"struct.std::_Rb_tree_node_base.17.99.509.534"** undef, align 8, !tbaa !0 + unreachable +} + +; CHECK: @test1 +; CHECK: stwu + +declare void @llvm.memset.p0i8.i64(i8* nocapture, i8, i64, i32, i1) nounwind + +!0 = metadata !{metadata !"any pointer", metadata !1} +!1 = metadata !{metadata !"omnipotent char", metadata !2} +!2 = metadata !{metadata !"Simple C/C++ TBAA"}
