    • [Ada] Crash on inherited private operation in child package · 7f8ad8f0 
      2019-12-13  Ed Schonberg  <schonberg@adacore.com>

gcc/ada/

	* sem_ch7.adb (Analyze_Package_Body_Helper): Do not call
	Declare_Inherited_Private_Subprograms on s child body: the
	required operations have already been created when analyzing the
	corresponding package declaration. This prevents a redeclaration
	of inehrited operation, and a crash when inserting the new
	operation in the current scope.

    • [rs6000] Adjust vectorization cost for scalar COND_EXPR · 396c2a98 
      We found that the vectorization cost modeling on scalar COND_EXPR is a bit off
on rs6000.  One typical case is 548.exchange2_r, -Ofast -mcpu=power9 -mrecip
-fvect-cost-model=unlimited is better than -Ofast -mcpu=power9 -mrecip (the
default is -fvect-cost-model=dynamic) by 1.94%.  Scalar COND_EXPR is expanded
into compare + branch or compare + isel normally, either of them should be
priced more than the simple FXU operation.  This patch is to add additional
vectorization cost onto scalar COND_EXPR on top of builtin_vectorization_cost.
The idea to use additional cost value 2 instead of the others: 1) try various
possible value candidates from 1 to 5, 2 is the best measured on Power9.  2) 
from latency view, compare takes 3 cycles and isel takes 2 on Power9, it's 
2.5 times of simple FXU instruction which takes cost 1 in the current
modeling, it's close.  3) get fine SPEC2017 ratio on Power8 as well.

gcc/ChangeLog

    * config/rs6000/rs6000.c (adjust_vectorization_cost): New function.
    (rs6000_add_stmt_cost): Call adjust_vectorization_cost and update
    stmt_cost.
