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

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

199 directives. These directives are legal everywhere. They
200 can be used to patch away BRIG entries at the binary level.
201 Also add extra error detection for zeroed regions: make sure
202 the byteCount field is never zero.
203 * brig/brigfrontend/phsa.h: Added a new error prefix for
204 errors which are due to corrupted BRIG modules.

231 * brig-lang.c: Improved support for function and module scope
232 group segment variables. PRM specs defines function and module
233 scope group segment variables as an experimental feature. However,
234 PRM test suite uses and hcc relies on them. In addition, hcc
235 assumes certain group variable layout in its dynamic group segment
236 allocation code. We cannot have global group memory offsets if we
237 want to both have kernel-specific group segment size and multiple
238 kernels calling the same functions that use function scope group memory
239 variables. Now group segment is handled by separate book keeping of
240 module scope and function (kernel) offsets. Each function has a "frame"
241 in the group segment offset to which is given as an argument.
