Alexey Bataev	9aba41c822	[OPENMP] Temporary fix for processing of global variables in loops. Currently there is a bug in processing of global variables used as loop control variables in 'omp for/simd' constructs: these globals must be captured as private variables, but currently they are nor. This is a temporary bug fix for this problem until the correct solution is prepared. If a global var used as lcv without explicit mark as a private/linear/lastprivate the error message is emitted. llvm-svn: 221970	2014-11-14 04:08:45 +00:00
Alexander Musman	a5f070aec0	[OPENMP] Loop collapsing and codegen for 'omp simd' directive. This patch implements collapsing of the loops (in particular, in presense of clause 'collapse'). It calculates number of iterations N and expressions nesessary to calculate the nested loops counters values based on new iteration variable (that goes from 0 to N-1) in Sema.

[OPENMP] Loop collapsing and codegen for 'omp simd' directive.

This patch implements collapsing of the loops (in particular, in
presense of clause 'collapse'). It calculates number of iterations N
and expressions nesessary to calculate the nested loops counters
values based on new iteration variable (that goes from 0 to N-1)
in Sema. It also adds Codegen for 'omp simd', which uses
(and tests) this feature.
