From 1e07de352947aaf2f9137113cc594d8204da2b77 Mon Sep 17 00:00:00 2001 From: Reed Kotler Date: Fri, 9 Aug 2013 21:33:41 +0000 Subject: [PATCH] Add another intrinsic that LLVM gives an incorrect prototype to. I need to go through all the runtime routine list and see if there are any more I need to add for mips16 floating point. Prototypes must be correct or else I don't know to add a helper function call. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188106 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/Mips/Mips16ISelLowering.cpp | 1 + test/CodeGen/Mips/fixdfsf.ll | 18 ++++++++++++++++++ 2 files changed, 19 insertions(+) create mode 100644 test/CodeGen/Mips/fixdfsf.ll diff --git a/lib/Target/Mips/Mips16ISelLowering.cpp b/lib/Target/Mips/Mips16ISelLowering.cpp index 6ed1d9e1cba..c8d0a520eb8 100644 --- a/lib/Target/Mips/Mips16ISelLowering.cpp +++ b/lib/Target/Mips/Mips16ISelLowering.cpp @@ -90,6 +90,7 @@ static const Mips16Libcall HardFloatLibCalls[] = { }; static const Mips16IntrinsicHelperType Mips16IntrinsicHelper[] = { + {"__fixunsdfsi", "__mips16_call_stub_2" }, {"ceil", "__mips16_call_stub_df_2"}, {"ceilf", "__mips16_call_stub_sf_1"}, {"copysign", "__mips16_call_stub_df_10"}, diff --git a/test/CodeGen/Mips/fixdfsf.ll b/test/CodeGen/Mips/fixdfsf.ll new file mode 100644 index 00000000000..b08eefd7123 --- /dev/null +++ b/test/CodeGen/Mips/fixdfsf.ll @@ -0,0 +1,18 @@ +; RUN: llc -mtriple=mipsel-linux-gnu -march=mipsel -mcpu=mips16 -soft-float -mips16-hard-float -relocation-model=pic < %s | FileCheck %s -check-prefix=pic1 +; RUN: llc -mtriple=mipsel-linux-gnu -march=mipsel -mcpu=mips16 -soft-float -mips16-hard-float -relocation-model=pic < %s | FileCheck %s -check-prefix=pic2 + +@x = common global double 0.000000e+00, align 8 +@y = common global i32 0, align 4 + +; Function Attrs: nounwind optsize +define void @foo() { +entry: + %0 = load double* @x, align 8 + %conv = fptoui double %0 to i32 + store i32 %conv, i32* @y, align 4 +; pic1: lw ${{[0-9]+}}, %call16(__fixunsdfsi)(${{[0-9]+}}) +; pic2: lw ${{[0-9]+}}, %got(__mips16_call_stub_2)(${{[0-9]+}}) + ret void +} + + -- 2.34.1
