2020-12-16rs6000: Use subreg for QI/HI vector initKewen Lin3-11/+5
This patch is to use paradoxical subreg instead of zero_extend for promoting QI/HI to SI/DI when we want to construct one vector with these modes. Since we do the gpr->vsx movement and vector merge or pack later, the high part is useless and safe to use paradoxical subreg. It can avoid useless rlwinms generated for signed cases. Bootstrapped/regtested on powerpc64le-linux-gnu P9. gcc/ChangeLog: * config/rs6000/rs6000.c (rs6000_expand_vector_init): Use paradoxical subreg instead of zero_extend for QI/HI promotion. gcc/testsuite/ChangeLog: * gcc.target/powerpc/pr96933-1.c: Adjusted to check no rlwinm. * gcc.target/powerpc/pr96933-2.c: Likewise.

2020-12-15compiler: discard global sink variables with static initializersIan Lance Taylor4-2/+31
This is specifically for the test fixedbugs/issue23781.go, which builds a large static array. The code does compile and work without this change, but it takes a long time and generates a large object file. Discarding the unnecessary static initializer makes this test much faster.

2020-12-15c++: Fix return type deduction during satisfactionPatrick Palka2-2/+13
During satisfaction that's entered through the three-parameter version of satisfy_declaration_constraints, current_function_decl gets set to the dependent DECL_TEMPLATE_RESULT for sake of access checking. This makes the predicate in_template_function return true during satisfaction from this entrypoint, which in turn makes calls to mark_used exit early before it does its full processing. This leads to us accepting the invalid testcase below due to mark_used never attempting to deduce the return type of A::foo() and detecting failure thereof. It seems wrong for in_template_function to be true during instantiation or during satisfaction, so this patch makes in_template_function inspect the less volatile cfun->decl instead of current_function_decl. gcc/cp/ChangeLog: * pt.c (in_template_function): Inspect cfun->decl instead of current_function_decl. gcc/testsuite/ChangeLog: * g++.dg/cpp2a/concepts-requires23.C: New test.
