[PATCH] Export _NCPUWORDS as variable for access from within the gnat-rts

Hi, This patch will make the define _NCPUWORDS accessible for the ada runtime. It is necessary to model the pthread_attr_t implementation for rtems in Ada. We had a stack corruption because the C an Ada declarations of the type where out of synch. I will send the updated s-osinte-rtems.ads to

Sorry. I am trying to use j...@rtems.org more and this actually bounced from the rtems devel mailing list. I have a habit to break. :( On 10/29/2015 8:14 AM, Jan Sommer wrote: Hi, This patch will make the define _NCPUWORDS accessible for the ada runtime. It is necessary to model the pthread_at

_NCPUWORDS is defined in newlib in newlib/libc/sys/rtems/sys/cpuset.h and used to define the type cpu_set_t there. typedef struct _cpuset { cpu_set_word_t __bits[_NCPUWORDS]; } cpu_set_t; cpu_set_t is used for a field in the struct pthread_attr_t in file newlib/libc/include/types.h The Gnat Ad

Re: [PATCH 2/2] Export _NCPUWORDS for Ada

How is this tackled in the glibc/Linux support? Is the exact layout of the structures really interesting for Ada? I guess its sufficient to tell Ada the size and alignment of pthread_attr_t for example. On 29/10/15 22:10, Jan Sommer wrote: _NCPUWORDS is defined in newlib in newlib/libc/sys/rte
