[cfe-users] Clang optimization options with out dead code elimination?

[Guofeng Zhang via cfe-users]

Hi,

We use clang 8+. Does clang have options (not -O0) that do not remove dead
code when clang optimize the code?

We have a old project, now migrating to Clang. It works well with -O0, but
failed when use -O1 to -O3.

Thanks,

Guofeng
