Adding a new file libomp.rc.var in anticipation of more
name change commits.  This file is a copy of libiomp.rc.var.

The CMAKE_OSX_ARCHITECTURES CMake variable allows users to build
universal fat libraries that contain both i386 and x86_64 code.  These
changes allow this build by having the z_Linux_asm.s file detect the architecture
itself instead of receiving it through the build system.

Also, there was a LIBOMP_OSX_ARCHITECTURES CMake variable added to allow
people to only build libomp as a fat library and not the entire LLVM/Clang system.

A while back, Hal mentioned fixing a comment concerning balanced affinity.
http://lists.cs.uiuc.edu/pipermail/openmp-dev/2014-December/000358.html
I forgot about fixing it until now, but now is better than never.

Change check of __GNUC__ macro from:
__GNUC__ == 4 to __GNUC__ >= 4

llvm-svn: 238347

A while back, Hal suggested updating the GUIDEDLL_EXPORTS macro guard to 
a more descriptive name.  It represents a dynamic library build so 
KMP_DYNAMIC_LIB is a more suitable name.

The variable j is now checked so there is no possible
out-of-bounds issue when accessing __kmp_nested_nth.nth[] array.

llvm-svn: 238216

This off-by-one error could lead to an out-of-bounds access on the
cons_text_c[] array.

These fixes make doxygen happy.

These spelling errors are in comments and some debug messages.

Should be looking at parent_task->td_flags.final instead of the recently allocated task.

llvm-svn: 237959

The fix simply syncs up the new threads to have the same task_state and
task_team as the old threads.  The master thread is skipped,
because it shouldn't at this point have the team's task_team value yet
-- it should still have parent_team's task_team.  It gets pointed at
the new team's task_team later, after __kmp_allocate_team returns, and
the master has stored a memo of it's old task_state.

Remove runtime/CMakeLists.txt.old and runtime/src/CMakeLists.txt as
they no longer worked and were not being kept up to date.

D9302.partial2: cleanup of ittnotify checks, that eliminats redundant notifications in case of nested regions.

llvm-svn: 236631

llvm-svn: 236623

llvm-svn: 236619

ittnotify: change default notification mode to 3, which includes parallel regions, barriers + imbalance, loops, single regions reporting.

These are the actual changes in the runtime to issue OMPT-related functions. All of them are surrounded by #if OMPT_SUPPORT and can be disabled (which is the default).

This is a preparation patch to get information about the actual release status from nested locks for OMPT.

llvm-svn: 236114

The generation of the hierarchy used by hierarchical barrier improved in how the generation reacts to affinity set to none, or disabled, or no affinity available, or oversubscription. Some cleanup actions based on review comments to follow: need to use meaningful names instead of digital constants, e.g. use enumerators.

Replace some unsafe API calls with safe alternatives on Windows, prepare code for similar actions on other platforms - wrap unsafe API calls into macros.

llvm-svn: 233915

Eliminated the write to depth field of the machine_hierarchy data structure in __kmp_get_hierarchy(), thus fixing race condition. Now local variable used by each thread.
