If -fno-assume-phsa is given, these optimizations are disabled. With this flag, gccbrig can generate GENERIC that assumes we are targeting a phsa-runtime based implementation, which allows us to expose the work-item context accesses to retrieve WI IDs etc. which helps optimizers. First optimization that takes advantage of this is to get rid of the setworkitemid calls whenever we have non-inlined calls that use IDs internally. Other optimizations added in this commit: - expand absoluteid to similar level of simplicity as workitemid. At the moment absoluteid is the best indexing ID to end up with WG vectorization. - propagate ID variables closer to their uses. This is mainly to avoid known useless casts, which confuse at least scalar evolution analysis. - use signed long long for storing IDs. Unsigned integers have defined wraparound semantics, which confuse at least scalar evolution analysis, leading to unvectorizable WI loops. - also refactor some BRIG function generation helpers to brig_function. - no point in having the wi-loop as a for-loop. It's really a do...while and SCEV can analyze it just fine still. - add consts to ptrs etc. in BRIG builtin defs. Improves optimization opportunities. - add qualifiers to generated function parameters. Const and restrict on the hidden local/private pointers, the arg buffer and the context pointer help some optimizations. * brigfrontend/brig-basic-inst-handler.cc: See above. * brigfrontend/brig-branch-inst-handler.cc: See above. * brigfrontend/brig-cmp-inst-handler.cc: See above. * brigfrontend/brig-code-entry-handler.cc: See above. * brigfrontend/brig-code-entry-handler.h: See above. * brigfrontend/brig-control-handler.cc: See above. * brigfrontend/brig-cvt-inst-handler.cc: See above. * brigfrontend/brig-function-handler.cc: See above. * brigfrontend/brig-function.cc: See above. * brigfrontend/brig-function.h: See above. * brigfrontend/brig-label-handler.cc: See above. * brigfrontend/brig-lane-inst-handler.cc: See above. * brigfrontend/brig-mem-inst-handler.cc: See above. * brigfrontend/phsa.h: See above. * lang.opt: See above. 2018-05-04 Pekka Jääskeläinen * brigfrontend/brig-function-handler.cc: Skip multiple forward declarations of the same function. 2018-05-04 Pekka Jääskeläinen * brig-lang.c: Do not allow optimizations based on known C builtins. 2018-05-04 Pekka Jääskeläinen * brig-lang.c: Allow controlling strict aliasing from cmd line. 2018-05-04 Pekka Jääskeläinen * brigfrontend/brig-code-entry-handler.cc: The modulo in ID computation should not be needed. 2018-05-04 Pekka Jääskeläinen * brig-lang.c: Add support for whole program optimizations by marking the kernels externally visible. * brigfrontend/brig-branch-inst-handler.cc: See above. * brigfrontend/brig-function-handler.cc: See above. * brigfrontend/brig-function.cc: See above. * brigfrontend/brig-to-generic.cc: See above. * brigfrontend/brig-to-generic.h: See above. * brigfrontend/brig-variable-handler.h: See above. 2018-01-03 Richard Sandiford Alan Hayward David Sherwood * brigfrontend/brig-to-generic.cc (get_unsigned_int_type): Handle polynomial TYPE_VECTOR_SUBPARTS. * brigfrontend/brig-util.h (gccbrig_type_vector_subparts): Likewise. 2018-01-03 Jakub Jelinek Update copyright years. 2018-01-03 Richard Sandiford Alan Hayward David Sherwood * brigfrontend/brig-util.h (gccbrig_type_vector_subparts): New function. * brigfrontend/brig-basic-inst-handler.cc (brig_basic_inst_handler::build_shuffle): Use it instead of TYPE_VECTOR_SUBPARTS.

PRM specs defines function and module scope group segment variables as an experimental feature. However, PRM test suite uses and hcc relies on them. In addition, hcc assumes certain group variable layout in its dynamic group segment allocation code. We cannot have global group memory offsets if we want to both have kernel-specific group segment size and multiple kernels calling the same functions that use function scope group memory variables. Now group segment is handled by separate book keeping of module scope and function (kernel) offsets. Each function has a "frame" in the group segment offset to which is given as an argument. * brigfrontend/brig-branch-inst-handler.cc: See above. * brigfrontend/brig-code-entry-handler.cc: See above. * brigfrontend/brig-fbarrier-handler.cc: See above. * brigfrontend/brig-function-handler.cc: See above. * brigfrontend/brig-function.cc: See above. * brigfrontend/brig-function.h: See above. * brigfrontend/brig-to-generic.cc: See above. * brigfrontend/brig-to-generic.h: See above. * brigfrontend/brig-util.cc: See above. * brigfrontend/brig-util.h: See above. * brigfrontend/brig-variable-handler.cc: See above. 2017-09-25 Pekka Jääskeläinen * brigfrontend/brig-to-generic.cc: Ensure per WI copies of private variables are aligned too. 2017-09-17 Thomas Schwinge * Make-lang.in (GO_TEXI_FILES): Rename to...
