  79         Add flag -fassume-phsa that is on by default. If -fno-assume-phsa
  80         is given, these optimizations are disabled.  With this flag, gccbrig
  81         can generate GENERIC that assumes we are targeting a phsa-runtime
  82         based implementation, which allows us to expose the work-item context
  83         accesses to retrieve WI IDs etc.  which helps optimizers.
  84         First optimization that takes advantage of this is to get rid of
  85         the setworkitemid calls whenever we have non-inlined calls that
  86         use IDs internally.  Other optimizations added in this commit:
  87         - expand absoluteid to similar level of simplicity as workitemid.
  88         At the moment absoluteid is the best indexing ID to end up with
  89         WG vectorization.
  90         - propagate ID variables closer to their uses. This is mainly
  91         to avoid known useless casts, which confuse at least scalar
  92         evolution analysis.
  93         - use signed long long for storing IDs. Unsigned integers have
  94         defined wraparound semantics, which confuse at least scalar
  95         evolution analysis, leading to unvectorizable WI loops.
  96         - also refactor some BRIG function generation helpers to brig_function.
  97         - no point in having the wi-loop as a for-loop. It's really
  98         a do...while and SCEV can analyze it just fine still.
  99         - add consts to ptrs etc. in BRIG builtin defs.
 100         Improves optimization opportunities.
 101         - add qualifiers to generated function parameters.
 102         Const and restrict on the hidden local/private pointers,
 103         the arg buffer and the context pointer help some optimizations.

 274         * brig-lang.c: Improved support for function and module scope
 275         group segment variables.  PRM specs defines function and module
 276         scope group segment variables as an experimental feature. However,
 277         PRM test suite uses and hcc relies on them. In addition, hcc
 278         assumes certain group variable layout in its dynamic group segment
 279         allocation code.  We cannot have global group memory offsets if we
 280         want to both have kernel-specific group segment size and multiple
 281         kernels calling the same functions that use function scope group memory
 282         variables.  Now group segment is handled by separate book keeping of
 283         module scope and function (kernel) offsets. Each function has a "frame"
 284         in the group segment offset to which is given as an argument.
