Summary: need to pass codegen options through to lto
Product: tools
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: lto
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected], [email protected]
Some LTO options such as PIC and FP elimination should be passed from the
frontend through to the backend. For debugging, it'd be nice to pass -fast
through too.
Some of the options (like target triple) are stored in the .bc, but we need to
sort out what options go where and how we make them flow through from llvm-gcc
to the gold plugin, into libLTO and make it all the way to codegen. Every
option that llvm-gcc supports should probably have a matching option unless
it's in the bitcode.
