[llvm-commits] CVS: llvm/lib/Target/CBackend/Writer.cpp

[Reid Spencer]

Changes in directory llvm/lib/Target/CBackend:

Writer.cpp updated: 1.283 -> 1.284
---
Log message:

When truncating to bool, it is necessary to & with 1 for all casts that
can result in a bool. Previously PtrToInt, FPToUI and FPToSI were missing
this operation.
