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

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

242
243 * brig-lang.c: Improved support for function and module scope
244 group segment variables. PRM specs defines function and module
245 scope group segment variables as an experimental feature. However,
246 PRM test suite uses and hcc relies on them. In addition, hcc
247 assumes certain group variable layout in its dynamic group segment
248 allocation code. We cannot have global group memory offsets if we
249 want to both have kernel-specific group segment size and multiple
250 kernels calling the same functions that use function scope group memory
251 variables. Now group segment is handled by separate book keeping of
252 module scope and function (kernel) offsets. Each function has a "frame"
253 in the group segment offset to which is given as an argument.
