3         PR hsa/86371
4         * Make-lang.in (BRIGINCLUDES): Remove erroneous include path in $HOME.

10 2018-06-08  David Malcolm  <dmalcolm@redhat.com>
12         * brigfrontend/brig-to-generic.cc
13         (brig_to_generic::write_globals): Use TDF_NONE rather than 0.
14         (dump_function): Likewise.
16 2018-05-18  Richard Sandiford  <richard.sandiford@linaro.org>
18         * brigfrontend/brig-function.cc
19         (brig_function::get_builtin_for_hsa_opcode): Use BUILT_IN_FMA
20         for BRIG_OPCODE_FMA.
21         (brig_function::get_tree_code_for_hsa_opcode): Treat BUILT_IN_FMA
22         as a call.
24 2018-05-04  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
26         * brig/brigfrontend/brig-basic-inst-handler.cc:  Fix handling of NOPs.
28 2018-05-04  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
30         Add flag -fassume-phsa that is on by default. If -fno-assume-phsa
31         is given, these optimizations are disabled.  With this flag, gccbrig
32         can generate GENERIC that assumes we are targeting a phsa-runtime
33         based implementation, which allows us to expose the work-item context
34         accesses to retrieve WI IDs etc.  which helps optimizers.
35         First optimization that takes advantage of this is to get rid of
36         the setworkitemid calls whenever we have non-inlined calls that
37         use IDs internally.  Other optimizations added in this commit:
38         - expand absoluteid to similar level of simplicity as workitemid.
39         At the moment absoluteid is the best indexing ID to end up with
40         WG vectorization.
41         - propagate ID variables closer to their uses. This is mainly
42         to avoid known useless casts, which confuse at least scalar
43         evolution analysis.
44         - use signed long long for storing IDs. Unsigned integers have
45         defined wraparound semantics, which confuse at least scalar
46         evolution analysis, leading to unvectorizable WI loops.
47         - also refactor some BRIG function generation helpers to brig_function.
48         - no point in having the wi-loop as a for-loop. It's really
49         a do...while and SCEV can analyze it just fine still.
50         - add consts to ptrs etc. in BRIG builtin defs.
51         Improves optimization opportunities.
52         - add qualifiers to generated function parameters.
53         Const and restrict on the hidden local/private pointers,
54         the arg buffer and the context pointer help some optimizations.

103             Alan Hayward  <alan.hayward@arm.com>
104             David Sherwood  <david.sherwood@arm.com>
106         * brigfrontend/brig-to-generic.cc (get_unsigned_int_type): Handle
107         polynomial TYPE_VECTOR_SUBPARTS.
108         * brigfrontend/brig-util.h (gccbrig_type_vector_subparts): Likewise.
110 2018-01-03  Jakub Jelinek  <jakub@redhat.com>

153 2017-11-16  Henry Linjamäki  <henry.linjamaki@parmance.com>
155         Change internal representation of HSA registers. Instead
156         representing HSA's untyped registers as unsigned int the gccbrig
157         analyzes brig code and builds the register variables as a type
158         used in tree expressions at most. This gives better chance to
159         optimize CONVERT_VIEW_EXPRs away.
160         * brigfrontend/brig-code-entry-handler.cc: Add analysis method for
161         register type usage. Handle any-typed register variables.
162         * brigfrontend/brig-code-entry-handler.h: New declarations for the
163         above.
164         * brigfrontend/brig-copy-move-inst-handler.cc: Handle any-typed
165         register variables.
166         * brigfrontend/brig-cvt-inst-handler.cc: Likewise.
167         * brigfrontend/brig-function.cc: Build register variables as a
168         type based on results of analysis phase.
169         * brigfrontend/brig-function.h: Move HSA register count defines to
170         brig-utils.h.
171         * brigfrontend/brig-to-generic.cc: New analysis handler. Analyze
172         HSA register usage.
173         * brigfrontend/brig-to-generic.h: New declarations.
174         * brigfrontend/brig-util.cc: New utility functions.
175         * brigfrontend/brig-util.h: New declarations for the above.
177 2017-11-16  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
179         * gccbrig.texi: Added some documentation.
181 2017-10-31  Henry Linjamäki  <henry.linjamaki@parmance.com>
183         * brig-lang.c (brig_langhook_type_for_mode): Fix PR 82771.
185 2017-10-23  Richard Sandiford  <richard.sandiford@linaro.org>
187         * brig-lang.c (brig_langhook_type_for_mode): Use scalar_int_mode
188         and scalar_float_mode.
190 2017-10-09  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
192         * brigfrontend/brig-to-generic.cc: Support BRIG_KIND_NONE
193         directives.  These directives are legal everywhere.  They
194         can be used to patch away BRIG entries at the binary level.
195         Also add extra error detection for zeroed regions: make sure
196         the byteCount field is never zero.
197         * brig/brigfrontend/phsa.h: Added a new error prefix for
198         errors which are due to corrupted BRIG modules.
200 2017-10-09  Henry Linjamäki  <henry.linjamaki@parmance.com>
202         * brigfrontend/brig-branch-inst-handler.cc: The call code
203         still failed a few test cases. Now all PRM cases pass again.
205 2017-10-03  Henry Linjamäki  <henry.linjamaki@parmance.com>
207         * brigfrontend/brig-branch-inst-handler.cc: Fix (more) crash with
208         calls with more than 4 args.  It missed a reference which is required
209         because vector expansion can move the object to another location.
211 2017-09-29  Henry Linjamäki  <henry.linjamaki@parmance.com>
213         * brigfrontend/brig-branch-inst-handler.cc: Fix crash with
214         calls with more than 4 args. Also fix a misexecution issue
215         with kernels that have both unexpanded ID functions and
216         calls to subfunctions.
218 2017-09-28  Henry Linjamäki  <henry.linjamaki@parmance.com>
220         * brig-lang.c: Added function attributes and their handlers.
221         Make BRIGFE 3-level optimize by default.
223 2017-09-27  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
225         * brig-lang.c: Improved support for function and module scope
226         group segment variables.  PRM specs defines function and module
227         scope group segment variables as an experimental feature. However,
228         PRM test suite uses and hcc relies on them. In addition, hcc
229         assumes certain group variable layout in its dynamic group segment
230         allocation code.  We cannot have global group memory offsets if we
231         want to both have kernel-specific group segment size and multiple
232         kernels calling the same functions that use function scope group memory
233         variables.  Now group segment is handled by separate book keeping of
234         module scope and function (kernel) offsets. Each function has a "frame"
235         in the group segment offset to which is given as an argument.
236         * brigfrontend/brig-branch-inst-handler.cc: See above.

248 2017-09-25  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
250         * brigfrontend/brig-to-generic.cc: Ensure per WI copies of
251         private variables are aligned too.
253 2017-09-17  Thomas Schwinge  <thomas@codesourcery.com>
255         * Make-lang.in (GO_TEXI_FILES): Rename to...

258         (brig.srcinfo, brig.man, brig.srcman, brig.install-man)
259         ($(DESTDIR)$(man1dir)/$(GCCBRIG_INSTALL_NAME)$(man1ext)):
260         Uncomment/enable targets.
261         (gccbrig.pod): New target.
262         * gccbrig.texi: New file.
264 2017-08-04  Henry Linjamäki  <henry.linjamaki@parmance.com>
266         Fix PR 81713
267         * brigfrontend/brig-basic-inst-handler.cc: replace build_int_cst with
268         bitsize_int in building BIT_FIELD_REF.
269         * brigfrontend/brig-code-entry-handler.cc: likewise.
271 2017-07-05  Richard Sandiford  <richard.sandiford@linaro.org>
272             Alan Hayward  <alan.hayward@arm.com>
273             David Sherwood  <david.sherwood@arm.com>
275         * brig-c.h (brig_type_for_mode): Remove "enum" before "machine_mode".
276         * brig-lang.c (brig_langhook_type_for_mode): Likewise.
278 2017-07-04  Jakub Jelinek  <jakub@redhat.com>
280         * brigfrontend/brig-function.cc: Include profile-count.h.
281         * brigfrontend/brig-to-generic.cc: Likewise.
283 2017-05-18  Thomas Schwinge  <thomas@codesourcery.com>
285         * brigfrontend/brig-to-generic.h (class brig_to_generic): Use
286         "dump_flags_t" for "m_dump_flags" member.
288 2017-05-13  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
290         * brigfrontend/brig-code-entry-handler.cc
291         (brig_code_entry_handler::build_address_operand): Fix
292         an assertion when doing an 'lda' of a private array
293         offset.
295 2017-05-03  Pekka Jääskeläinen  <pekka.jaaskelainen@parmance.com>
297         * brigfrontend/brig-code-entry-handler.cc
298         (brig_code_entry_handler::build_address_operand): Fix a bug
299         with reg+offset addressing on 32b segments. In large mode,
300         the offset is treated as 32bits unless it's global, readonly or
301         kernarg address space.
