44 2018-05-18  Richard Sandiford  <richard.sandiford@linaro.org>
46         * brigfrontend/brig-function.cc
47         (brig_function::get_builtin_for_hsa_opcode): Use BUILT_IN_FMA
48         for BRIG_OPCODE_FMA.
49         (brig_function::get_tree_code_for_hsa_opcode): Treat BUILT_IN_FMA
50         as a call.
52 2018-05-04  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
54         * brigfrontend/brig-basic-inst-handler.cc: Fix handling of NOPs.
56 2018-05-04  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
58         Add flag -fassume-phsa that is on by default. If -fno-assume-phsa
59         is given, these optimizations are disabled.  With this flag, gccbrig
60         can generate GENERIC that assumes we are targeting a phsa-runtime
61         based implementation, which allows us to expose the work-item context
62         accesses to retrieve WI IDs etc.  which helps optimizers.
63         First optimization that takes advantage of this is to get rid of
64         the setworkitemid calls whenever we have non-inlined calls that
65         use IDs internally.  Other optimizations added in this commit:
66         - expand absoluteid to similar level of simplicity as workitemid.
67         At the moment absoluteid is the best indexing ID to end up with
68         WG vectorization.
69         - propagate ID variables closer to their uses. This is mainly
70         to avoid known useless casts, which confuse at least scalar
71         evolution analysis.
72         - use signed long long for storing IDs. Unsigned integers have
73         defined wraparound semantics, which confuse at least scalar
74         evolution analysis, leading to unvectorizable WI loops.
75         - also refactor some BRIG function generation helpers to brig_function.
76         - no point in having the wi-loop as a for-loop. It's really
77         a do...while and SCEV can analyze it just fine still.
78         - add consts to ptrs etc. in BRIG builtin defs.
79         Improves optimization opportunities.
80         - add qualifiers to generated function parameters.
81         Const and restrict on the hidden local/private pointers,
82         the arg buffer and the context pointer help some optimizations.

114 2018-05-04  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
116         * brigfrontend/brig-code-entry-handler.cc: The modulo in
117         ID computation should not be needed.
119 2018-05-04  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
121         * brig-lang.c: Add support for whole program

131             Alan Hayward  <alan.hayward@arm.com>
132             David Sherwood  <david.sherwood@arm.com>
134         * brigfrontend/brig-to-generic.cc (get_unsigned_int_type): Handle
135         polynomial TYPE_VECTOR_SUBPARTS.
136         * brigfrontend/brig-util.h (gccbrig_type_vector_subparts): Likewise.
138 2018-01-03  Jakub Jelinek  <jakub@redhat.com>
140         Update copyright years.
142 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>

161 2017-12-15  Jakub Jelinek  <jakub@redhat.com>
163         * brig-lang.c (brig_attribute_table): Swap affects_type_identity
164         and handler fields, adjust comments.

179         on 32b machines.
181 2017-11-16  Henry Linjamäki  <henry.linjamaki@parmance.com>
183         Change internal representation of HSA registers. Instead
184         representing HSA's untyped registers as unsigned int the gccbrig
185         analyzes brig code and builds the register variables as a type
186         used in tree expressions at most. This gives better chance to
187         optimize CONVERT_VIEW_EXPRs away.
188         * brigfrontend/brig-code-entry-handler.cc: Add analysis method for
189         register type usage. Handle any-typed register variables.
190         * brigfrontend/brig-code-entry-handler.h: New declarations for the
191         above.
192         * brigfrontend/brig-copy-move-inst-handler.cc: Handle any-typed
193         register variables.
194         * brigfrontend/brig-cvt-inst-handler.cc: Likewise.
195         * brigfrontend/brig-function.cc: Build register variables as a
196         type based on results of analysis phase.
197         * brigfrontend/brig-function.h: Move HSA register count defines to
198         brig-utils.h.
199         * brigfrontend/brig-to-generic.cc: New analysis handler. Analyze
200         HSA register usage.
201         * brigfrontend/brig-to-generic.h: New declarations.
202         * brigfrontend/brig-util.cc: New utility functions.
203         * brigfrontend/brig-util.h: New declarations for the above.
205 2017-11-16  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
207         * gccbrig.texi: Added some documentation.
209 2017-10-31  Henry Linjamäki  <henry.linjamaki@parmance.com>
211         * brig-lang.c (brig_langhook_type_for_mode): Fix PR 82771.
213 2017-10-23  Richard Sandiford  <richard.sandiford@linaro.org>
215         * brig-lang.c (brig_langhook_type_for_mode): Use scalar_int_mode
216         and scalar_float_mode.
218 2017-10-09  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
220         * brigfrontend/brig-to-generic.cc: Support BRIG_KIND_NONE
221         directives.  These directives are legal everywhere.  They
222         can be used to patch away BRIG entries at the binary level.
223         Also add extra error detection for zeroed regions: make sure
224         the byteCount field is never zero.
225         * brigfrontend/phsa.h: Added a new error prefix for
226         errors which are due to corrupted BRIG modules.
228 2017-10-09  Henry Linjamäki  <henry.linjamaki@parmance.com>
230         * brigfrontend/brig-branch-inst-handler.cc: The call code
231         still failed a few test cases. Now all PRM cases pass again.
233 2017-10-03  Henry Linjamäki  <henry.linjamaki@parmance.com>
235         * brigfrontend/brig-branch-inst-handler.cc: Fix (more) crash with
236         calls with more than 4 args.  It missed a reference which is required
237         because vector expansion can move the object to another location.
239 2017-09-29  Henry Linjamäki  <henry.linjamaki@parmance.com>
241         * brigfrontend/brig-branch-inst-handler.cc: Fix crash with
242         calls with more than 4 args. Also fix a misexecution issue
243         with kernels that have both unexpanded ID functions and
244         calls to subfunctions.
246 2017-09-28  Henry Linjamäki  <henry.linjamaki@parmance.com>
248         * brig-lang.c: Added function attributes and their handlers.
249         Make BRIGFE 3-level optimize by default.
251 2017-09-27  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
253         * brig-lang.c: Improved support for function and module scope
254         group segment variables.  PRM specs defines function and module
255         scope group segment variables as an experimental feature. However,
256         PRM test suite uses and hcc relies on them. In addition, hcc
257         assumes certain group variable layout in its dynamic group segment
258         allocation code.  We cannot have global group memory offsets if we
259         want to both have kernel-specific group segment size and multiple
260         kernels calling the same functions that use function scope group memory
261         variables.  Now group segment is handled by separate book keeping of
262         module scope and function (kernel) offsets. Each function has a "frame"
263         in the group segment offset to which is given as an argument.
264         * brigfrontend/brig-branch-inst-handler.cc: See above.
265         * brigfrontend/brig-code-entry-handler.cc: See above.
266         * brigfrontend/brig-fbarrier-handler.cc: See above.

272         * brigfrontend/brig-util.cc: See above.
273         * brigfrontend/brig-util.h: See above.
274         * brigfrontend/brig-variable-handler.cc: See above.
276 2017-09-25  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
278         * brigfrontend/brig-to-generic.cc: Ensure per WI copies of
279         private variables are aligned too.
281 2017-09-17  Thomas Schwinge  <thomas@codesourcery.com>
283         * Make-lang.in (GO_TEXI_FILES): Rename to...
284         (BRIG_TEXI_FILES): ... this.
285         (doc/gccbrig.info, doc/gccbrig.dvi, doc/gccbrig.pdf, brig.info)
286         (brig.srcinfo, brig.man, brig.srcman, brig.install-man)
287         ($(DESTDIR)$(man1dir)/$(GCCBRIG_INSTALL_NAME)$(man1ext)):
288         Uncomment/enable targets.
289         (gccbrig.pod): New target.
290         * gccbrig.texi: New file.
292 2017-08-04  Henry Linjamäki  <henry.linjamaki@parmance.com>
294         Fix PR 81713
295         * brigfrontend/brig-basic-inst-handler.cc: replace build_int_cst with
296         bitsize_int in building BIT_FIELD_REF.
297         * brigfrontend/brig-code-entry-handler.cc: likewise.
299 2017-07-05  Richard Sandiford  <richard.sandiford@linaro.org>
300             Alan Hayward  <alan.hayward@arm.com>
301             David Sherwood  <david.sherwood@arm.com>
303         * brig-c.h (brig_type_for_mode): Remove "enum" before "machine_mode".
304         * brig-lang.c (brig_langhook_type_for_mode): Likewise.
306 2017-07-04  Jakub Jelinek  <jakub@redhat.com>
308         * brigfrontend/brig-function.cc: Include profile-count.h.
309         * brigfrontend/brig-to-generic.cc: Likewise.
311 2017-05-18  Thomas Schwinge  <thomas@codesourcery.com>
313         * brigfrontend/brig-to-generic.h (class brig_to_generic): Use
314         "dump_flags_t" for "m_dump_flags" member.
316 2017-05-13  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
318         * brigfrontend/brig-code-entry-handler.cc
319         (brig_code_entry_handler::build_address_operand): Fix
320         an assertion when doing an 'lda' of a private array
321         offset.
323 2017-05-03  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
325         * brigfrontend/brig-code-entry-handler.cc
326         (brig_code_entry_handler::build_address_operand): Fix a bug
327         with reg+offset addressing on 32b segments. In large mode,
328         the offset is treated as 32bits unless it's global, readonly or
329         kernarg address space.
331 2016-02-01  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
