Hello Aldy,
Some of the middle end changes I made in the previous patch was not
flying for the C++. Here is a fixed patch where the middle-end changes will
work for both C and C++.
With this email, I am attaching the patch for C along with the middle
end changes. Is this Ok for the branch?
Here are the ChangeLog entries:
gcc/ChangeLog
2013-11-30 Balaji V. Iyer <balaji.v.i...@intel.com>
* omp-low.c (expand_simd_clones): Added a new parameter called "type."
(ipa_omp_simd_clone): Added a call to expand_simd_clones when Cilk Plus
is enabled.
gcc/c-family/ChangeLog
2013-11-30 Balaji V. Iyer <balaji.v.i...@intel.com>
* c-common.c (c_common_attribute_table): Added "cilk plus elemental"
attribute.
gcc/c/ChangeLog
2013-11-30 Balaji V. Iyer <balaji.v.i...@intel.com>
* c-parser.c (struct c_parser::elem_fn_tokens): Added new field.
(c_parser_declaration_or_fndef): Added a check if elem_fn_tokens
field in parser is not empty. If not-empty, call the function
c_parser_finish_omp_declare_simd.
(c_parser_elem_fn_vectorlength): New function.
(c_parser_elem_fn_expr_list): Likewise.
(c_finish_elem_fn_tokens): Likewise.
(c_parser_attributes): Added a elem_fn_tokens parameter. Added a
check for vector attribute and if so call c_parser_elem_fn_expr_list.
Also, called c_finish_elem_fn_tokens when Cilk Plus is enabled.
(c_finish_omp_declare_simd): Added a check if elem_fn_tokens in
parser field is non-empty. If so, parse them as you would parse
the omp declare simd pragma.
gcc/testsuite/ChangeLog
2013-11-30 Balaji V. Iyer <balaji.v.i...@intel.com>
* c-c++-common/cilk-plus/EF/ef_test.c: New test.
* c-c++-common/cilk-plus/EF/ef_test2.c: Likewise.
* c-c++-common/cilk-plus/EF/vlength_errors.c: Likewise.
* c-c++-common/cilk-plus/EF/ef_error.c: Likewise.
* c-c++-common/cilk-plus/EF/ef_error2.c: Likewise.
* gcc.dg/cilk-plus/cilk-plus.exp: Added calls for the above tests.
Thanks,
Balaji V. Iyer.
