From 9b4baf169299141692e07adedeff691b71e95fda Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Mon, 24 Sep 2007 05:27:37 +0000 Subject: claim that "st" is from the 80-bit register file. This causes x87-using inline asm to die with: ScheduleDAG.cpp:269: failed assertion `false && "Couldn't find the register class"' instead of: failed assertion `RegMap->getRegClass(VReg) == RC && "Register class of operand and regclass of use don't agree!"' yay. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42259 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/X86/X86ISelLowering.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/lib/Target/X86/X86ISelLowering.cpp b/lib/Target/X86/X86ISelLowering.cpp index e52b653..1e5e478 100644 --- a/lib/Target/X86/X86ISelLowering.cpp +++ b/lib/Target/X86/X86ISelLowering.cpp @@ -5279,7 +5279,7 @@ X86TargetLowering::getRegForInlineAsmConstraint(const std::string &Constraint, // GCC calls "st(0)" just plain "st". if (StringsEqualNoCase("{st}", Constraint)) { Res.first = X86::ST0; - Res.second = X86::RSTRegisterClass; + Res.second = X86::RFP80RegisterClass; } return Res; -- cgit v1.1
