[llvm-bugs] [Bug 36122] New: Incorrect codegen flags initialization (LTO)

2018-01-27 Thread via llvm-bugs 
https://bugs.llvm.org/show_bug.cgi?id=36122

Bug ID: 36122
   Summary: Incorrect codegen flags initialization (LTO)
   Product: lld
   Version: unspecified
  Hardware: PC
OS: Windows NT
Status: NEW
  Severity: normal
  Priority: P
 Component: COFF
  Assignee: unassignedb...@nondot.org
  Reporter: ignacio.slipk...@gmail.com
CC: llvm-bugs@lists.llvm.org

The function InitTargetOptionsFromCodeGenFlags which is called from LTO.cpp
should get its flags from somewhere else if invoked from linker, because things
like FunctionSections are false even if /Gy is passed to the compiler.

Not sure if it affects ELF linker too.
