Release Notes for Intel(R) Cilk(TM) Plus for GCC Release 1.0
This release of Intel Cilk Plus language extensions for GCC implements the
following features from the Intel Cilk Plus Language Specification:
* Keywords for Tasking: _Cilk_spawn, _Cilk_sync, and _Cilk_for, as well as
the pragma to allow users to control the grainsize of the _Cilk_for loop.
* Hyperobjects: Full support for reducers is provided for both C and C++.
* SIMD Loops : Pragma SIMD support and the following clauses:
- vectorlength
- linear
- assert
- reduction
- private
Note: These pragmas are supported for the innermost loops only.
* Array Notations: Array notations are supported for C and C++. Along with
this, we have also implemented the following builtin reduction functions:
- __sec_reduce_add
- __sec_reduce_mul
- __sec_reduce_max
- __sec_reduce_min
- __sec_reduce_max_ind
- __sec_reduce_min_ind
- __sec_reduce_all_zero
- __sec_reduce_all_nonzero
- __sec_reduce_any_zero
- __sec_reduce_any_nonzero
- __sec_implicit_index
* Elemental functions: Elemental functions allow the compiler to create vector
version of a function so that the vectorizer can use them to vectorize
functions.
Known Issues:
* Exception support - Exceptions are not supported for Cilk keywords.
