#4223: LLVM slower then NCG, C example
-------------------------------+--------------------------------------------
Reporter: dterei | Owner: dterei
Type: bug | Status: new
Priority: normal | Component: Compiler (LLVM)
Version: 6.12.3 | Keywords:
Os: Linux | Testcase:
Architecture: x86_64 (amd64) | Failure: Runtime performance bug
-------------------------------+--------------------------------------------
Comment(by dterei):
Here are the different LLVM opt flag timings on Windows/32bit:
{{{
* llvm (O0): 2.033s
* llvm (O3): 2.041s
}}}
Basically no difference (within the variation amount). So not worse but we
are still wasting compile time with no gain!
