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

146 Change internal representation of HSA registers. Instead
147 representing HSA's untyped registers as unsigned int the gccbrig

216 * brig-lang.c: Improved support for function and module scope
217 group segment variables. PRM specs defines function and module
218 scope group segment variables as an experimental feature. However,
219 PRM test suite uses and hcc relies on them. In addition, hcc
220 assumes certain group variable layout in its dynamic group segment
221 allocation code. We cannot have global group memory offsets if we
222 want to both have kernel-specific group segment size and multiple
223 kernels calling the same functions that use function scope group memory
224 variables. Now group segment is handled by separate book keeping of
225 module scope and function (kernel) offsets. Each function has a "frame"
226 in the group segment offset to which is given as an argument.
