           Summary: llvm-gcc should pass -fast to llc when compiling at -O0
           Product: new-bugs
           Version: unspecified
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: new bugs
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: baldrick at free.fr


If compiling at -O0 then no optimizations should be performed [*].
However it looks like codegen still performs optimizations -
passing -fast to llc would disable these.

[*] People compiling at -O0 might want speed, or an unoptimized
baseline for debugging purposes etc.
