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

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