| Fix In Release: | ARMCLANG_5.0.0.LTS* |
| Affected Platform/Device: | default |
| Workaround: | - Use only a single optimization option on the command line
- Follow the precedence rules described |
| Description |
|
When the compiler is invoked with multiple optimization flags on the command line, the goal of linktime optimization may not agree with the goal of the first optimization. Expectation When multiple optimization options are passed to the compiler, the last one seen takes precedence for both the initial compilation as well as LTO Observation tiarmclang -O3 -O0 -flto project.c -Wl,lnk.cmd Correctly compiles project.c with no optimization (-O0) |
