unspec_volatile is documented in the gcc internals manual. There are many examples of using it in the existing gcc backends. The purpose is to permit describing instructions which can not be adequately expressed in RTL, such as the x86 cld instruction. > somebody can explain the procedure for gcc debugging ? http://gcc.gnu.org/wiki/DebuggingGCC The mailing list gcc@gcc.gnu.org is intended for use by the gcc developers. Please consider taking general questions to the mailing list gcc-h...@gcc.gnu.org. Thanks. Ian
