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

 178         Change internal representation of HSA registers. Instead
 179         representing HSA's untyped registers as unsigned int the gccbrig
 180         analyzes brig code and builds the register variables as a type
 181         used in tree expressions at most. This gives better chance to

 218         Also add extra error detection for zeroed regions: make sure
 219         the byteCount field is never zero.

 221         errors which are due to corrupted BRIG modules.

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