Pragmas for code generation

Doc ID 018512 Rev 2

169/185

Remarks

This pragma reverses the bitfield allocation, so that bitfields are arranged from the opposite

side of the storage unit from that ordinarily used on the target. The compiler still orders the

bits within a single bitfield such that the lowest-valued bit is in the right-most position.

This pragma does not correspond to any panel setting. By default, this pragma is disabled.

Note:

Limitation: please be aware of the following limitations when this pragma is set to on:

- the data types of the bit-fields must be the same data type

- the structure (struct) or class must not contain non-bit-field members; however, the

structure (struct) can be the member of another structure

store_object_files

Controls the storage location of object data, either in the target data directory or as a

separate file.

Syntax

#pragma store_object_files on | off | reset

Remarks

By default, the IDE writes object data to the project’s target data directory. When this

pragma is on, the object data is written to a separate object file.

Note:

For some targets, the object file emitted may not be recognized as actual object data.

This pragma does not correspond to any panel setting. By default, this pragma is off.
