The ARM compiler recognizes pragmas of the following form:
#pragma [no_]feature‑name
Note
Pragmas override related command‑line options. For example, #pragma arm overrides the ‑‑thumb command‑line option.
For more information see the relevant section in the Compiler Reference Guide:
- Pragmas for saving and restoring the pragma state
The following pragmas enable you to save and restore the pragma state:
- Pragmas controlling multiple optimizations
These pragmas enable you to assign multiple optimizations on individual functions. The pragmas must be placed outside of a function, and you cannot apply more than one of these optimizations on a function. The following pragmas control these optimizations:
- Pragmas controlling code generation
The following pragmas control how code is generated:
- Pragmas controlling
PreCompiled Header(PCH) processing The following pragmas control PCH processing:
- Pragmas controlling anonymous structures and unions
The following pragma controls the use of anonymous structures and unions:
- Pragmas controlling diagnostic messages
The following pragmas control the output of the diagnostic messages that have a
‑Dpostfix in the message number:
