Unexpected -Wvolatile-register-var warnings when using volatile qualifier for memory‑mapped registers
When developing Embedded C code, engineers enable diagnostics such as -Wall -Wextra -Wvolatile-register-var to catch problematic register accesses while using #pragma GCC diagnostic push/pop or #pragma diag_suppress to silence the warning in specific blocks. The goal is to retain useful alerts for genuine issues without exposing notification noise from known
