25.4.13 Assigning Objects to Sections

The __section() specifier can be used to indicate that an object should be located in the named section. This is typically used when the object has special and unique linking requirements that cannot be addressed by existing compiler features.

Use the native keywords discussed in the Differences section to look up information on the semantics of this specifier.

Example

The following shows a variable which uses the __section keyword.

int __section("comSec") commonFlag;

Differences

When targeting AVR MCUs using the MPLAB XC8 compiler or when using the other compilers, the section attribute has been used to indicate a different destination section name. The __section() specifier works in a similar way to the attribute.

Migration to the CCI

When building with MPLAB XC16, XC-DSC or XC32 compilers, or with the MPLAB XC8 compiler for AVR MCUs, change any occurrence of the section attribute, for example, from:

int __attribute__((section("myVars"))) intMask;

to:

int __section("myVars") intMask;

Caveats

None.
