<p>GCC supports several types of pragmas, primarily in order to compile
|
||
|
|
code originally written for other compilers. Note that in general
|
||
|
|
we do not recommend the use of pragmas; See <a href="Function-Attributes.html#Function-Attributes">Function Attributes</a>,
|
||
|
|
for further explanation.
