Product: libraries
Version: trunk

OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: Scalar Optimizations
AssignedTo: [EMAIL PROTECTED]

GCC supports -fno-builtin-abs and other to selectively disable builtins. This
does not work sometimes because SimplifyLibCalls is not informed about this.
One solution is to use an attribute on call instruction.
