Subject: [PATCH 1/2] [Flang][OpenMP] Use simdloop operation only for omp simd
pragma
OpenMP standard differentiates between omp simd (2.9.3.1) and
omp do/for simd (2.9.3.2 for OpenMP 5.0 standard) pragmas.
The first one describes the loop which needs to be vectorized.
The second pragma describes the loop which needs to be workshared
between existing threads. Each thread can use SIMD instructions
to execute its chunk of the loop.
That's why we need to model
!$omp simd
do-loop
as omp.simdloop operation and add compiler hints for vectorization.
The worksharing loop:
!$omp do simd
do-loop
should be represented as worksharing loop.
Currently Flang denotes both type of OpenMP pragmas by omp.simdloop
operation. In consequence we cannot differentiate between:
!$omp parallel simd
do-loop
and
!$omp parallel do simd
do-loop
The second loop should be workshared between multiple threads.
The first one describes the loop which needs to be redundantly
executed by multiple threads. Current Flang implementation
does not perform worksharing for `!$omp do simd` pragma and
generates valid code only for first case.
