The Intel® C++ Compiler supports the following pragmas to ensure compatibility with other compilers.
The following pragmas are compatible with the Microsoft* compiler. For more information about these pragmas, go to the Microsoft* Developer Network (http://msdn.microsoft.com).
Pragma |
Description |
---|---|
alloc_text |
Names the code section where the specified function definitions are to reside. |
auto_inline |
Excludes any function defined within the range where off is specified from being considered as candidates for automatic inline expansion. |
bss_seg |
Indicates to the compiler the segment where uninitialized variables are stored in the .obj file. |
check_stack |
The on argument indicates that stack checking should be enabled for functions that follow and the off argument indicates that stack checking should be disabled for functions that follow. |
code_seg |
Specifies a code section where functions are to be allocated. |
comment |
Places a comment record into an object file or executable file. |
component |
Controls collecting of browse information or dependency information from within source files. |
conform |
Specifies the run-time behavior of the /Zc:forScope compiler option. |
const_seg |
Specifies the segment where functions are stored in the .obj file. |
data_seg |
Specifies the default section for initialized data. |
deprecated |
Indicates that a function, type, or any other identifier may not be supported in a future release or indicates that a function, type, or any other identifier should not be used any more. |
fenv_access |
Informs an implementation that a program may test status flags or run under a non-default control mode. |
float_control |
Specifies floating-point behavior for a function. |
fp_contract |
Allows or disallows the implementation to contract expressions. |
loop |
Controls how the loop code will be considered or excluded from consideration by the auto-vectorizer. |
init_seg |
Specifies the section to contain C++ initialization code for the translation unit. |
message |
Displays the specified string literal to the standard output device (stdout). |
optimize |
Specifies optimizations to be performed on functions below the pragma or until the next optimize pragma; implemented to partly support the Microsoft* implementation of same pragma; for the Intel® C++ Compiler implementation, see the optimize reference page. |
pointers_to_members |
Specifies whether a pointer to a class member can be declared before its associated class definition and is used to control the pointer size and the code required to interpret the pointer. |
pop_macro |
Sets the value of the specified macro to the value on the top of the stack. |
push_macro |
Saves the value of the specified macro on the top of the stack. |
region/endregion |
Specifies a code segment in the Microsoft* Visual Studio* Code Editor that expands and contracts by using the outlining feature. |
section |
Creates a section in an .obj file. Once a section is defined, it remains valid for the remainder of the compilation. |
vtordisp |
The on argument enables the generation of hidden vtordisp members and the off disables them. push argument pushes the current vtordisp setting to the internal compiler stack. pop argument removes the top record from the compiler stack and restores the removed value of vtordisp. |
warning |
Allows selective modification of the behavior of compiler warning messages. |
weak |
Declares symbol you enter to be weak. |
The following pragmas are compatible with other compilers. For more information about these pragmas, see the documentation for the specified compiler.
Pragma |
Description |
---|---|
include_directory |
HP-compatible pragma. It appends the string argument to the list of places to search for #include files. |
poison |
GCC-compatible pragma. It labels the identifiers you want removed from your program; an error results when compiling a "poisoned" identifier; #pragma POISON is also supported. |
options |
GCC-compatible pragma; It sets the alignment of fields in structures. |
weak |
GCC-compatible pragma, it declares the symbol you enter to be weak. |
