Pragmas for code generation

Doc ID 018512 Rev 2

21.7

instmgr_file

Controls where the instance manager database is written, to the target data directory or to a

separate file.

Syntax

#pragma instmgr_file "name"

Remarks

When the Use Instance Manager option is on, the IDE writes the instance manager

database to the project’s data directory. If the #pragma instmgr_file is used, the

database is written to a separate file.

Also, a separate instance file is always written when the command-line tools are used.

Note:

Should you need to report a bug, you can use this option to create a separate instance

manager database, which can then be sent to technical support with your bug report.

21.8

longlong

Controls the availability of the long long type.

Syntax

#pragma longlong on | off | reset

Remarks

When this pragma is enabled and the compiler is translating “C90” source code (ISO/IEC

9899-1990 standard), the compiler recognizes a data type named long long. The long

long

type holds twice as many bits as the long data type.

By default, this pragma is on for processors that support this type. It is off when generating

code for processors that do not support, or cannot turn on, the long long type.

21.9

longlong_enums

Controls whether or not enumerated types may have the size of the long long type.

Syntax

#pragma longlong_enums on | off | reset

Remarks

This pragma lets you use enumerators that are large enough to be long long integers. It

is ignored if you enable the enumsalwaysint pragma (described in enumsalwaysint).

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

21.10

min_enum_size

Specifies the size, in bytes, of enumeration types.
