Bug #: 13182
Summary: -flto and -Wl,--as-needed combination removes needed
libraries
Product: binutils
Version: 2.21
Status: NEW
Severity: normal
Priority: P2
Component: ld
AssignedTo: unassig...@sources.redhat.com
ReportedBy: krisztian.koc...@optimaster.eu
Classification: Unclassified
Created attachment 5929

Verbose linker output.
When I try to build udev with gcc-4.6.1 and binutils-2.21.1, the accelerometer
module fails to link because of undefined references to sqrt, atan, etc.
Unfortunately -lm is explicitly specified. If I remove -flto or
-Wl,--as-needed, the module links successfully.
Verbose linker output is attached.
