2.6. Pragmas

The following pragmas are supported by the tiarmclang compiler:

• clang section text
• clang section data

2.6.1. clang section text

The clang section text pragma will place enclosed functions within a named section, which can then be placed with the linker using a linker command file.

Syntax

#pragma clang section text=”scn_name”

The setting is reset to the default section name using

#pragma clang section text=”“

Example

The following use of the clang section text pragma will cause the enclosed function to be included in a section called .text.functions

#include <stdio.h>

#pragma clang section text=".text.functions"

int main() {
  emit_msg();
  emit_msg();
  emit_msg();
}

#pragma clang section text=""

2.6.2. clang section data

The clang section data pragma will place enclosed variables within a named section, which can then be placed with the linker using a linker command file.

Syntax

#pragma clang section data=”scn_name”

The setting is reset to the default section name using

#pragma clang section data=”“

Example

The following use of the clang section data pragma will cause the enclosed variables to be included in a section called .data.variables

#include <stdio.h>

#pragma clang section data=".data.variables"

int var1 = 39;
char *myString = "this is a test";

#pragma clang section data=""

extern void func(int, char*);

int main() {
  func(var1, myString);
}
