Bug ID: 71317
   Summary: Compiling gnat for rtems fails at s-taprop.adb
   Product: gcc
   Version: 6.1.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: ada
  Assignee: unassigned at gcc dot gnu.org
  Reporter: soja-lists at aries dot uberspace.de
  Target Milestone: ---

Recent versions of gnat fail to build for RTEMS because of missing/wrong
declarations in s-osinte-rtems.ads which is inculded in s-taprop.

I will provide a patch for gcc-5, gcc-6 and trunk.

--- Comment #2 from Jan Sommer  ---
It's an undefined reference to clock_getres and warnings that there are
multiple definitions in Get_Page_Size.

I submitted a patch which adds the clock_getres declaration and fixes the
Get_Page_Size declaration to be like in other s-osinte-*.ads files.

[Bug ada/68169] New: s-osinte-rtems.ads is out of synch with type definitions of current newlib

Bug ID: 68169
   Summary: s-osinte-rtems.ads is out of synch with type
definitions of current newlib
   Product: gcc
   Version: 4.9.4
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: ada
  Assignee: unassigned at gcc dot gnu.org
  Reporter: soja-lists at aries dot uberspace.de
  Target Milestone: ---

For rtems the type definition of phtread_attr_t in s-osinte-rtems.ads and the
corresponding one of current newlib are not equivalent.

Thus not enough memory is reserved by ada for this type and the call to the
initializer will cause a stack corruption at least for arm-rtems4.11-targets.

I have tested the problem with the gcc4_9-branch and will provide a patch.
The rtems-developers are aware of the problem.
