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

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

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