Building Single Tree for a Specific Set of CFLAGS

Hi For RTEMS, we normally build a multilib'ed gcc+newlib, but I have a case where the CPU model is something not covered by our multilibs and not one we are keen to add. I've looked around but not found anything that makes me feel confident. What's the magic for building a gcc+newlib with a singl

gmplib.org Down

Hi In the RTEMS Source Builder, we fetch GMP directly from gmplib.org. It has been down a few hours. We have been telling people to either fetch it from ftp.gnu.org or http://gcc.gnu.org/pub/gcc/infrastructure/ for now. Does anyone have any insight into gmplib.org being down? Is there any reason

Re: GCC for C6x DSPs

Hi again, Richard probably knows this but the gcc docs from the git master have this: '-march=NAME' This specifies the name of the target architecture. GCC uses this name to determine what kind of instructions it can emit when generating assembly code. Permissible names are: 'c

Use of register keyword for Globals

Hi In the SPARC port of RTEMS, there is a global variable assigned to a register for performance reasons. This is the near decade old line of code: register struct Per_CPU_Control *_SPARC_Per_CPU_current __asm__( "g6" ); Per https://gcc.gnu.org/onlinedocs/gcc/Global-Register-Variables.html, this
