Hello,
Assuming a plugin (e.g. MELT) add a new pragma using PLUGIN_PRAGMAS, is
this pragma usable from Ada or Fortran code?
I am not very familiar with Ada or Fortran. I believe Ada has some
syntax for pragmas -but do Ada pragma have the same API inside GCC
plugins as C or C++ pragmas?- and I am

Actually tree-if-conversion does take care of transforming the inner loop
into one BB to enable vectorization. So we don't have the cross-BB
combine problem.

In PR43902, Jim has posted a patch to add support for widening
multiply-accumulate to tree-ssa-math-opts. They are represented as a
GIMPLE_SINGLE_RHS with a WIDEN_MULT_PLUS_EXPR tree which holds the
actual operands of the multiply-accumulate. I've modified this a bit so
that we now support gimple
