GNUARM GCC Signal Reserved Names Documentation?

Greetings:

Please direct me to documentation that describes the ARM unique features of GNUARM GCC. Is there a special GCCARM library manual that defines the unique, non ANSI syntax signal names and any special ARM library functions?

Many thanks in advance!

Oooops! - Just in case there are other GNU_ARM_GCC newbees expecting to find the ARM specific documentation in a separate supplement it is in fact covered within the main GCC manual which includes documentation for many hardware ports of GCC:

Many thanks to those that contributed to this comprehensive GCC documentation package!
