C/C++ Compiler and Run-Time Library
Support for G21-Based Options And Extensions
The compiler supports most of the switches and extensions of the
cc219x
previous GNU-based compiler release. For a list of absolute or modified
options, see "Compiler Switch Modifications" on page
ANSI C Extensions
The following extensions are no longer supported, or their functions have
been modified:
•
typeof
expression.
• Complex types:
sions were used to define complex numbers. Although you cannot
write complex number literals, you can have a complex type
defined with real and imaginary components. These types need to
be managed by the programmer. Support for complex types using
such an approach is used in the
ous complex types.
• Compound statements within expressions — This extension was
used to declare variables within an expression. You can achieve
these results using
• Iterator types:
expressions that were used as a shorthand for working with arrays.
• Assigning variables to specific registers:
used to declare a variable and specify a machine register in which to
store it.
If you use any of these extensions in your C source code, revise that
source.
