Description

I get this error when trying to compile the Tango user library (0.99.8) using ldc tip (r1297):

ldc: /build/buildd-llvm_2.5-2-i386-G3bib9/llvm-2.5/lib/Target/X86/X86FloatingPoint.cpp:1072: void<unnamed>::FPS::handleSpecialFP(llvm::ilist_iterator<llvm::MachineInstr>&): Assertion `Op.isUse() && (Op.isKill() || getFPReg(Op) == FirstFPRegOp || MI->killsRegister(Op.getReg())) && "Ret only defs operands, and values aren't live beyond it"' failed.

Compilation of tango/math/Math.d failed

Building the compiler and the runtime works fine.

I believe this is a bug in LLVM 2.5. Please try using LLVM svn.

  • status changed from new to closed.
  • resolution set to invalid.

Seems to work with LLVM trunk.

I had to make an undocumented hack to compile ldc against LLVM trunk though:

ccmake ./ -DCMAKE_CXX_FLAGS:string=-DLLVM_REV=71035

(thanks impulze for the help!)
