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

132 Change internal representation of HSA registers. Instead
133 representing HSA's untyped registers as unsigned int the gccbrig
134 analyzes brig code and builds the register variables as a type
135 used in tree expressions at most. This gives better chance to
136 optimize CONVERT_VIEW_EXPRs away.

169 * brigfrontend/brig-to-generic.cc: Support BRIG_KIND_NONE
170 directives. These directives are legal everywhere. They
171 can be used to patch away BRIG entries at the binary level.
172 Also add extra error detection for zeroed regions: make sure
173 the byteCount field is never zero.
174 * brig/brigfrontend/phsa.h: Added a new error prefix for
175 errors which are due to corrupted BRIG modules.
177 2017-10-09 Henry Linjamäki <henry.linjamaki@parmance.com>

180 still failed a few test cases. Now all PRM cases pass again.

184 * brigfrontend/brig-branch-inst-handler.cc: Fix (more) crash with
185 calls with more than 4 args. It missed a reference which is required
186 because vector expansion can move the object to another location.
188 2017-09-29 Henry Linjamäki <henry.linjamaki@parmance.com>
190 * brigfrontend/brig-branch-inst-handler.cc: Fix crash with
191 calls with more than 4 args. Also fix a misexecution issue
192 with kernels that have both unexpanded ID functions and
193 calls to subfunctions.
195 2017-09-28 Henry Linjamäki <henry.linjamaki@parmance.com>
197 * brig-lang.c: Added function attributes and their handlers.
198 Make BRIGFE 3-level optimize by default.
200 2017-09-27 Pekka Jääskeläinen <pekka.jaaskelainen@parmance.com>
202 * brig-lang.c: Improved support for function and module scope
203 group segment variables. PRM specs defines function and module
204 scope group segment variables as an experimental feature. However,
205 PRM test suite uses and hcc relies on them. In addition, hcc
206 assumes certain group variable layout in its dynamic group segment
207 allocation code. We cannot have global group memory offsets if we
208 want to both have kernel-specific group segment size and multiple
209 kernels calling the same functions that use function scope group memory
210 variables. Now group segment is handled by separate book keeping of
211 module scope and function (kernel) offsets. Each function has a "frame"
212 in the group segment offset to which is given as an argument.
