44 Add flag -fassume-phsa that is on by default. If -fno-assume-phsa
45 is given, these optimizations are disabled. With this flag, gccbrig
46 can generate GENERIC that assumes we are targeting a phsa-runtime
47 based implementation, which allows us to expose the work-item context
48 accesses to retrieve WI IDs etc. which helps optimizers.
49 First optimization that takes advantage of this is to get rid of
50 the setworkitemid calls whenever we have non-inlined calls that
51 use IDs internally. Other optimizations added in this commit:
52 - expand absoluteid to similar level of simplicity as workitemid.
53 At the moment absoluteid is the best indexing ID to end up with
55 - propagate ID variables closer to their uses. This is mainly
56 to avoid known useless casts, which confuse at least scalar
58 - use signed long long for storing IDs. Unsigned integers have
59 defined wraparound semantics, which confuse at least scalar
60 evolution analysis, leading to unvectorizable WI loops.
61 - also refactor some BRIG function generation helpers to brig_function.
62 - no point in having the wi-loop as a for-loop. It's really
63 a do...while and SCEV can analyze it just fine still.
64 - add consts to ptrs etc. in BRIG builtin defs.
65 Improves optimization opportunities.
66 - add qualifiers to generated function parameters.
67 Const and restrict on the hidden local/private pointers,
68 the arg buffer and the context pointer help some optimizations.

169 Change internal representation of HSA registers. Instead
170 representing HSA's untyped registers as unsigned int the gccbrig
171 analyzes brig code and builds the register variables as a type
172 used in tree expressions at most. This gives better chance to
173 optimize CONVERT_VIEW_EXPRs away.
174 * brigfrontend/brig-code-entry-handler.cc: Add analysis method for
175 register type usage. Handle any-typed register variables.
176 * brigfrontend/brig-code-entry-handler.h: New declarations for the

202 and scalar_float_mode.
204 2017-10-09 Pekka Jääskeläinen <pekka.jaaskelainen@parmance.com>
206 * brigfrontend/brig-to-generic.cc: Support BRIG_KIND_NONE
207 directives. These directives are legal everywhere. They
208 can be used to patch away BRIG entries at the binary level.
209 Also add extra error detection for zeroed regions: make sure
210 the byteCount field is never zero.
211 * brig/brigfrontend/phsa.h: Added a new error prefix for
212 errors which are due to corrupted BRIG modules.
214 2017-10-09 Henry Linjamäki <henry.linjamaki@parmance.com>
216 * brigfrontend/brig-branch-inst-handler.cc: The call code
217 still failed a few test cases. Now all PRM cases pass again.
219 2017-10-03 Henry Linjamäki <henry.linjamaki@parmance.com>
221 * brigfrontend/brig-branch-inst-handler.cc: Fix (more) crash with
222 calls with more than 4 args. It missed a reference which is required
223 because vector expansion can move the object to another location.
225 2017-09-29 Henry Linjamäki <henry.linjamaki@parmance.com>
227 * brigfrontend/brig-branch-inst-handler.cc: Fix crash with
228 calls with more than 4 args. Also fix a misexecution issue
229 with kernels that have both unexpanded ID functions and
230 calls to subfunctions.
232 2017-09-28 Henry Linjamäki <henry.linjamaki@parmance.com>
234 * brig-lang.c: Added function attributes and their handlers.
235 Make BRIGFE 3-level optimize by default.
237 2017-09-27 Pekka Jääskeläinen <pekka.jaaskelainen@parmance.com>
239 * brig-lang.c: Improved support for function and module scope
240 group segment variables. PRM specs defines function and module
241 scope group segment variables as an experimental feature. However,
242 PRM test suite uses and hcc relies on them. In addition, hcc
243 assumes certain group variable layout in its dynamic group segment
244 allocation code. We cannot have global group memory offsets if we
245 want to both have kernel-specific group segment size and multiple
246 kernels calling the same functions that use function scope group memory
247 variables. Now group segment is handled by separate book keeping of
248 module scope and function (kernel) offsets. Each function has a "frame"
249 in the group segment offset to which is given as an argument.

315 kernarg address space.
