1 2018-05-18  Richard Sandiford  <richard.sandiford@linaro.org>
3         * brigfrontend/brig-function.cc
4         (brig_function::get_builtin_for_hsa_opcode): Use BUILT_IN_FMA
5         for BRIG_OPCODE_FMA.
6         (brig_function::get_tree_code_for_hsa_opcode): Treat BUILT_IN_FMA
7         as a call.
9 2018-05-04  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
11         * brig/brigfrontend/brig-basic-inst-handler.cc:  Fix handling of NOPs.
13 2018-05-04  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
15         Add flag -fassume-phsa that is on by default. If -fno-assume-phsa
16         is given, these optimizations are disabled.  With this flag, gccbrig
17         can generate GENERIC that assumes we are targeting a phsa-runtime
18         based implementation, which allows us to expose the work-item context
19         accesses to retrieve WI IDs etc.  which helps optimizers.
20         First optimization that takes advantage of this is to get rid of
21         the setworkitemid calls whenever we have non-inlined calls that
22         use IDs internally.  Other optimizations added in this commit:
23         - expand absoluteid to similar level of simplicity as workitemid.
24         At the moment absoluteid is the best indexing ID to end up with
25         WG vectorization.
26         - propagate ID variables closer to their uses. This is mainly
27         to avoid known useless casts, which confuse at least scalar
28         evolution analysis.
29         - use signed long long for storing IDs. Unsigned integers have
30         defined wraparound semantics, which confuse at least scalar
31         evolution analysis, leading to unvectorizable WI loops.
32         - also refactor some BRIG function generation helpers to brig_function.
33         - no point in having the wi-loop as a for-loop. It's really
34         a do...while and SCEV can analyze it just fine still.
35         - add consts to ptrs etc. in BRIG builtin defs.
36         Improves optimization opportunities.
37         - add qualifiers to generated function parameters.
38         Const and restrict on the hidden local/private pointers,
39         the arg buffer and the context pointer help some optimizations.

71 2018-05-04  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
73         * brig/brigfrontend/brig-code-entry-handler.cc: The modulo in

88             Alan Hayward  <alan.hayward@arm.com>
89             David Sherwood  <david.sherwood@arm.com>
91         * brigfrontend/brig-to-generic.cc (get_unsigned_int_type): Handle
92         polynomial TYPE_VECTOR_SUBPARTS.
93         * brigfrontend/brig-util.h (gccbrig_type_vector_subparts): Likewise.
95 2018-01-03  Jakub Jelinek  <jakub@redhat.com>
97         Update copyright years.

103         * brigfrontend/brig-util.h (gccbrig_type_vector_subparts): New
104         function.
105         * brigfrontend/brig-basic-inst-handler.cc
106         (brig_basic_inst_handler::build_shuffle): Use it instead of
107         TYPE_VECTOR_SUBPARTS.
108         (brig_basic_inst_handler::build_unpack): Likewise.

120         * brig-lang.c (brig_attribute_table): Swap affects_type_identity
121         and handler fields, adjust comments.

136         on 32b machines.
138 2017-11-16  Henry Linjamäki  <henry.linjamaki@parmance.com>
140         Change internal representation of HSA registers. Instead
141         representing HSA's untyped registers as unsigned int the gccbrig
142         analyzes brig code and builds the register variables as a type
143         used in tree expressions at most. This gives better chance to
144         optimize CONVERT_VIEW_EXPRs away.
145         * brigfrontend/brig-code-entry-handler.cc: Add analysis method for
146         register type usage. Handle any-typed register variables.
147         * brigfrontend/brig-code-entry-handler.h: New declarations for the
148         above.
149         * brigfrontend/brig-copy-move-inst-handler.cc: Handle any-typed
150         register variables.
151         * brigfrontend/brig-cvt-inst-handler.cc: Likewise.
152         * brigfrontend/brig-function.cc: Build register variables as a
153         type based on results of analysis phase.
154         * brigfrontend/brig-function.h: Move HSA register count defines to
155         brig-utils.h.
156         * brigfrontend/brig-to-generic.cc: New analysis handler. Analyze
157         HSA register usage.
158         * brigfrontend/brig-to-generic.h: New declarations.
159         * brigfrontend/brig-util.cc: New utility functions.
160         * brigfrontend/brig-util.h: New declarations for the above.
162 2017-11-16  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
164         * gccbrig.texi: Added some documentation.
166 2017-10-31  Henry Linjamäki  <henry.linjamaki@parmance.com>
168         * brig-lang.c (brig_langhook_type_for_mode): Fix PR 82771.
170 2017-10-23  Richard Sandiford  <richard.sandiford@linaro.org>
172         * brig-lang.c (brig_langhook_type_for_mode): Use scalar_int_mode
173         and scalar_float_mode.
175 2017-10-09  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
177         * brigfrontend/brig-to-generic.cc: Support BRIG_KIND_NONE
178         directives.  These directives are legal everywhere.  They
179         can be used to patch away BRIG entries at the binary level.
180         Also add extra error detection for zeroed regions: make sure
181         the byteCount field is never zero.
182         * brig/brigfrontend/phsa.h: Added a new error prefix for
183         errors which are due to corrupted BRIG modules.
185 2017-10-09  Henry Linjamäki  <henry.linjamaki@parmance.com>
187         * brigfrontend/brig-branch-inst-handler.cc: The call code
188         still failed a few test cases. Now all PRM cases pass again.
190 2017-10-03  Henry Linjamäki  <henry.linjamaki@parmance.com>
192         * brigfrontend/brig-branch-inst-handler.cc: Fix (more) crash with
193         calls with more than 4 args.  It missed a reference which is required
194         because vector expansion can move the object to another location.
196 2017-09-29  Henry Linjamäki  <henry.linjamaki@parmance.com>
198         * brigfrontend/brig-branch-inst-handler.cc: Fix crash with
199         calls with more than 4 args. Also fix a misexecution issue
200         with kernels that have both unexpanded ID functions and
201         calls to subfunctions.
203 2017-09-28  Henry Linjamäki  <henry.linjamaki@parmance.com>
205         * brig-lang.c: Added function attributes and their handlers.
206         Make BRIGFE 3-level optimize by default.
208 2017-09-27  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
210         * brig-lang.c: Improved support for function and module scope
211         group segment variables.  PRM specs defines function and module
212         scope group segment variables as an experimental feature. However,
213         PRM test suite uses and hcc relies on them. In addition, hcc
214         assumes certain group variable layout in its dynamic group segment
215         allocation code.  We cannot have global group memory offsets if we
216         want to both have kernel-specific group segment size and multiple
217         kernels calling the same functions that use function scope group memory
218         variables.  Now group segment is handled by separate book keeping of
219         module scope and function (kernel) offsets. Each function has a "frame"
220         in the group segment offset to which is given as an argument.

233 2017-09-25  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
235         * brigfrontend/brig-to-generic.cc: Ensure per WI copies of
236         private variables are aligned too.
238 2017-09-17  Thomas Schwinge  <thomas@codesourcery.com>
240         * Make-lang.in (GO_TEXI_FILES): Rename to...
241         (BRIG_TEXI_FILES): ... this.
242         (doc/gccbrig.info, doc/gccbrig.dvi, doc/gccbrig.pdf, brig.info)
243         (brig.srcinfo, brig.man, brig.srcman, brig.install-man)
244         ($(DESTDIR)$(man1dir)/$(GCCBRIG_INSTALL_NAME)$(man1ext)):
245         Uncomment/enable targets.
246         (gccbrig.pod): New target.
247         * gccbrig.texi: New file.
249 2017-08-04  Henry Linjamäki  <henry.linjamaki@parmance.com>
251         Fix PR 81713
252         * brigfrontend/brig-basic-inst-handler.cc: replace build_int_cst with
253         bitsize_int in building BIT_FIELD_REF.
254         * brigfrontend/brig-code-entry-handler.cc: likewise.
256 2017-07-05  Richard Sandiford  <richard.sandiford@linaro.org>
257             Alan Hayward  <alan.hayward@arm.com>
258             David Sherwood  <david.sherwood@arm.com>
260         * brig-c.h (brig_type_for_mode): Remove "enum" before "machine_mode".
261         * brig-lang.c (brig_langhook_type_for_mode): Likewise.
263 2017-07-04  Jakub Jelinek  <jakub@redhat.com>
265         * brigfrontend/brig-function.cc: Include profile-count.h.
266         * brigfrontend/brig-to-generic.cc: Likewise.
268 2017-05-18  Thomas Schwinge  <thomas@codesourcery.com>
270         * brigfrontend/brig-to-generic.h (class brig_to_generic): Use
271         "dump_flags_t" for "m_dump_flags" member.
273 2017-05-13  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
275         * brigfrontend/brig-code-entry-handler.cc
276         (brig_code_entry_handler::build_address_operand): Fix
277         an assertion when doing an 'lda' of a private array
278         offset.
280 2017-05-03  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
282         * brigfrontend/brig-code-entry-handler.cc
283         (brig_code_entry_handler::build_address_operand): Fix a bug
284         with reg+offset addressing on 32b segments. In large mode,
285         the offset is treated as 32bits unless it's global, readonly or
286         kernarg address space.
288 2016-02-01  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
