[PATCH 10/10] libcc1: use unique_ptr more

This changes libcc1 to use unique_ptr in a few more places, removing some manual memory management. libcc1/ChangeLog 2021-01-03 Tom Tromey * libcp1.cc (struct libcp1) : Use unique_ptr. (~libcp1): Remove. (libcp1_compile, libcp1_set_triplet_regexp) (libcp

[PATCH 09/10] libcc1: add more uses of 'deleter'

This changes libcc1 to use the 'deleter' template in a few more places. The template and basic specializations are moved to a new header, then some unmarshall functions are changed to use this code. This change avoids the need to repeat cleanup code in the unmarshallers. libcc1/ChangeLog 2021-01-

[PATCH 08/10] libcc1: add deleter objects

This adds deleter objects for various kinds of protocol pointers to libcc1. Existing specializations of argument_wrapper are then replaced with a single specialization that handles all pointer types via the appropriate deleter. The result here is a bit nicer because the argument_wrapper boilerpla

[PATCH 04/10] libcc1: delete copy constructor and assignment operators

Change libcc1 to use "= delete" for the copy constructor and assignment operator, rather than the old approach of private methods that are nowhere defined. libcc1/ChangeLog 2021-01-03 Tom Tromey * rpc.hh (argument_wrapper): Use delete for copy constructor. * connection.hh (clas

[PATCH 06/10] libcc1: use variadic templates for "rpc"

This changes libcc1 to use variadic templates for the "rpc" functions. This simplifies the code and removes some possibility for mistakes. libcc1/ChangeLog 2021-01-03 Tom Tromey * libcp1.cc (rpc): Use variadic template. Remove overloads. * libcc1.cc (rpc): Use variadic templat

[PATCH 07/10] libcc1: use std::vector when building function types

This changes libcc1 to use std::vector in the code that builds function types. This avoids some explicit memory management. libcc1/ChangeLog 2021-01-03 Tom Tromey * libcp1plugin.cc (plugin_build_function_type): Use std::vector. * libcc1plugin.cc (plugin_build_function_type): U

[PATCH 05/10] libcc1: use variadic templates for "call"

This changes libcc1 to use variadic templates for the "call" functions. The primary benefit is that this simplifies the code. libcc1/ChangeLog 2021-01-03 Tom Tromey * rpc.hh (call): Use variadic template. Remove overloads. * marshall.hh (marshall): Add base overload. Use var

[PATCH 01/10] libcc1: use templates to unmarshall enums

Now that C++11 can be used in GCC, libcc1 can be changed to use templates and type traits to handle unmarshalling all kinds of enums. libcc1/ChangeLog 2021-01-03 Tom Tromey * marshall.hh (cc1_plugin::unmarshall): Use type traits. * marshall-cp.hh (cc1_plugin::unmarshall): Remov

[PATCH 00/10] C++11-based improvements for libcc1

This short series uses C++11 features to simplify libcc1. This brings the code closer to how I pictured it when I first wrote it. (It would be further improved by std::apply, but this isn't available until C++17.) I built and tested this against git GDB on x86-64 Fedora 32. Note that the C++ pl

[PATCH] loop-niter: Recognize popcount idioms even with char, short and __int128 [PR95771]

Hi! As the testcase shows, we punt unnecessarily on popcount loop idioms if the type is smaller than int or larger than long long. Smaller type than int can be handled by zero-extending the argument to unsigned int, and types twice as long as long long by doing __builtin_popcountll on both halves
