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

[John Criswell]

Changes in directory llvm/lib/Target/CBackend:

Writer.cpp updated: 1.241 -> 1.242
---
Log message:

Fixed PR#596:
Add parenthesis around the value being negated; that way, if the value
begins with a minus sign (e.g. negative integer), we won't generate a
C predecrement operator by mistake.
