2019-11-28rs6000: Use memory_operand for all simple {l,st}*brx instructionsSegher Boessenkool2-4/+13
We run fwprop before combine, very early even in the case of fwprop1; and fwprop1 will change memory addressing to what it considers cheaper. After the "common" change, it now changes the indexed store instruction in the testcase to be to a constant address. But that is not an improvement at all: the byte reverse instructions only exist in the indexed form, so they will not match anymore. This patch changes the patterns for the byte reverse instructions to allow plain memory_operand, letting reload fix this up.

This patch fixes profile updates while cloning. When new clone is produced its global profile is subtracted from the original function. If the original function profile drops to 0 we want to switch from global profiles to global0 profiles which is implemented by combine_with_ipa_count_within. However this is done on all edges independnetly and it may happen that we end up combining global and globa0 profiles in one functions which is not a good idea.

This patch fixes problem in profile_count::to_sreal_scale. We our porfile counters can be function local, global (ipa) or function local but globally 0. The last is used to hold static estimates for functions executed 0 times in profile. Now only one 64bit value is stored and if we compute frequency of global0 counter in global counter we mix them up and return non-zero value incorrectly. I also implemented unit test, but will commit sanity checking separately from fixes: there are multiple bugs in this area I tracked down. * profile-count.c (profile_count::to_sreal_scale): Handle correctly combination of globa0 and global counters..

This patch implements C++20 class template argument deduction for alias templates, which works by a moderately arcane transformation of the deduction guides for the underlying class template.

2019-11-27PR c++/92206 - ICE with typedef to dependent alias.Jason Merrill8-39/+89
rsandifo's patch for 92206 demonstrated a problem with the existing checking for alias template specializations: they were returning false for a typedef to an alias template specialization. Which is sometimes what the caller wants, and sometimes not: Sometimes we're interested in whether the type was written as an alias template-id, and sometimes whether it represents one. The testcase illustrates a case that remained wrong with the earlier patch: if the typedef is itself an alias template specialization, we can't strip an underlying dependent alias. * pt.c (dependent_alias_template_spec_p) (alias_template_specialization_p): Add transparent_typedefs parameter.
