From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/cp/ChangeLog | 1562 +++ gcc/cp/ChangeLog-1993 | 613 ++ gcc/cp/ChangeLog-1994 | 5412 ++++++++++

X = 3" extension has been removed; you must now use "new X(3)". + +* G++ no longer allows in-class initializations of static data members + that do not have arithmetic or enumeration type. For example: + + struct S { + static const char* const p = "abc"; + }; + + is no longer accepted. + + Use the standards-conformant form: + + struct S { + static const char* const p; + }; + + const char* const S::p = "abc"; + + instead. + + (ISO C++ is even stricter; it does not allow in-class + initializations of floating-point types.) + +*** Changes in GCC 3.1: + +* -fhonor-std and -fno-honor-std have been removed. -fno-honor-std was + a workaround to allow std compliant code to work with the non-std + compliant libstdc++-v2. libstdc++-v3 is std compliant. + +* The C++ ABI has been fixed so that `void (A::*)() const' is mangled as + "M1AKFvvE", rather than "MK1AFvvE" as before. This change only affects + pointer to cv-qualified member function types. + +* The C++ ABI has been changed to correctly handle this code: + + struct A { + void operator delete[] (void *, size_t); + }; + + struct B : public A { + }; + + new B[10]; + + The amount of storage allocated for the array will be greater than + it was in 3.0, in order to store the number of elements in the + array, so that the correct size can be passed to `operator delete[]' + when the array is deleted. Previously, the value passed to + `operator delete[]' was unpredictable. + + This change will only affect code that declares a two-argument + `operator delete[]' with a second parameter of type `size_t' + in a base class, and does not override that definition in a + derived class. + +* The C++ ABI has been changed so that: + + struct A { + void operator delete[] (void *, size_t); + void operator delete[] (void *); + }; + + does not cause unnecessary storage to be allocated when an array of + `A' objects is allocated. + + This change will only affect code that declares both of these + forms of `operator delete[]', and declared the two-argument form + before the one-argument form. + +* The C++ ABI has been changed so that when a parameter is passed by value, + any cleanup for that parameter is performed in the caller, as specified + by the ia64 C++ ABI, rather than the called function as before. As a + result, classes with a non-trivial destructor but a trivial copy + constructor will be passed and returned by invisible reference, rather + than by bitwise copy as before. + +* G++ now supports the "named return value optimization": for code like + + A f () { + A a; + ... + return a; + } + + G++ will allocate 'a' in the return value slot, so that the return + becomes a no-op. For this to work, all return statements in the function + must return the same variable. + +*** Changes in GCC 3.0: + +* Support for guiding declarations has been removed. + +* G++ now supports importing member functions from base classes with a + using-declaration. + +* G++ now enforces access control for nested types. + +* In some obscure cases, functions with the same type could have the + same mangled name. This bug caused compiler crashes, link-time clashes, + and debugger crashes. Fixing this bug required breaking ABI + compatibility for the functions involved. The functions in questions + are those whose types involve non-type template arguments whose + mangled representations require more than one digit. + +* Support for assignment to `this' has been removed. This idiom + was used in the very early days of C++, before users were allowed + to overload `operator new'; it is no longer allowed by the C++ + standard. + +* Support for signatures, a G++ extension, have been removed. + +* Certain invalid conversions that were previously accepted will now + be rejected. For example, assigning function pointers of one type + to function pointers of another type now requires a cast, whereas + previously g++ would sometimes accept the code even without the + cast. + +* G++ previously allowed `sizeof (X::Y)' where Y was a non-static + member of X, even if the `sizeof' expression occurred outside + of a non-static member function of X (or one of its derived classes, + or a member-initializer for X or one of its derived classes.) This + extension has been removed. + +* G++ no longer allows you to overload the conditional operator (i.e., + the `?:' operator.) + +* The "named return value" extension: + + int f () return r { r = 3; } + + has been deprecated, and will be removed in a future version of G++. + +*** Changes in GCC 2.95: + +* Messages about non-conformant code that we can still handle ("pedwarns") + are now errors by default, rather than warnings. This can be reverted + with -fpermissive, and is overridden by -pedantic or -pedantic-errors. + +* String constants are now of type `const char[n]', rather than `char[n]'. + This can be reverted with -fno-const-strings. + +* References to functions are now supported. + +* Lookup of class members during class definition now works in all cases. + +* In overload resolution, type conversion operators are now properly + treated as always coming from the most derived class. + +* C9x-style restricted pointers are supported, using the `__restrict' + keyword. + +* You can now use -fno-implicit-inline-templates to suppress writing out + implicit instantiations of inline templates. Normally we do write them + out, even with -fno-implicit-templates, so that optimization doesn't + affect which instantiations are needed. + +* -fstrict-prototype now also suppresses implicit declarations. + +* Many obsolete options have been removed: -fall-virtual, -fmemoize-lookups, + -fsave-memoized, +e?, -fenum-int-equivalence, -fno-nonnull-objects. + +* Unused virtual functions can be discarded on some targets by specifying + -ffunction-sections -fvtable-gc to the compiler and --gc-sections to the + linker. Unfortunately, this only works on Linux if you're linking + statically. + +* Lots of bugs stomped. + +*** Changes in EGCS 1.1: + +* Namespaces are fully supported. The library has not yet been converted + to use namespace std, however, and the old std-faking code is still on by + default. To turn it off, you can use -fhonor-std. + +* Massive template improvements: + + member template classes are supported. + + template friends are supported. + + template template parameters are supported. + + local classes in templates are supported. + + lots of bugs fixed. + +* operator new now throws bad_alloc where appropriate. + +* Exception handling is now thread safe, and supports nested exceptions and + placement delete. Exception handling overhead on x86 is much lower with + GNU as 2.9. + +* protected virtual inheritance is now supported. + +* Loops are optimized better; we now move the test to the end in most + cases, like the C frontend does. + +* For class D derived from B which has a member 'int i', &D::i is now of + type 'int B::*' instead of 'int D::*'. + +* An _experimental_ new ABI for g++ can be turned on with -fnew-abi. The + current features of this are more efficient allocation of base classes + (including the empty base optimization), and more compact mangling of C++ + symbol names (which can be turned on separately with -fsquangle). This + ABI is subject to change without notice, so don't use it for anything + that you don't want to rebuild with every release of the compiler. + + As with all ABI-changing flags, this flag is for experts only, as all + code (including the library code in libgcc and libstdc++) must be + compiled with the same ABI. + +*** Changes in EGCS 1.0: + +* A public review copy of the December 1996 Draft of the ISO/ANSI C++ + standard is now available. See + + http://www.cygnus.com/misc/wp/ + + for more information. + +* g++ now uses a new implementation of templates. The basic idea is that + now templates are minimally parsed when seen and then expanded later. + This allows conformant early name binding and instantiation controls, + since instantiations no longer have to go through the parser. + + What you get: + + + Inlining of template functions works without any extra effort or + modifications. + + Instantiations of class templates and methods defined in the class + body are deferred until they are actually needed (unless + -fexternal-templates is specified). + + Nested types in class templates work. + + Static data member templates work. + + Member function templates are now supported. + + Partial specialization of class templates is now supported. + + Explicit specification of template parameters to function templates + is now supported. + + Things you may need to fix in your code: + + + Syntax errors in templates that are never instantiated will now be + diagnosed. + + Types and class templates used in templates must be declared + first, or the compiler will assume they are not types, and fail. + + Similarly, nested types of template type parameters must be tagged + with the 'typename' keyword, except in base lists. In many cases, + but not all, the compiler will tell you where you need to add + 'typename'. For more information, see + + http://www.cygnus.com/misc/wp/dec96pub/template.html#temp.res + + + Guiding declarations are no longer supported. Function declarations, + including friend declarations, do not refer to template instantiations. + You can restore the old behavior with -fguiding-decls until you fix + your code. + + Other features: + + + Default function arguments in templates will not be evaluated (or + checked for semantic validity) unless they are needed. Default + arguments in class bodies will not be parsed until the class + definition is complete. + + The -ftemplate-depth-NN flag can be used to increase the maximum + recursive template instantiation depth, which defaults to 17. If you + need to use this flag, the compiler will tell you. + + Explicit instantiation of template constructors and destructors is + now supported. For instance: + + template A::A(const A&); + + Still not supported: + + + Member class templates. + + Template friends. + +* Exception handling support has been significantly improved and is on by + default. The compiler supports two mechanisms for walking back up the + call stack; one relies on static information about how registers are + saved, and causes no runtime overhead for code that does not throw + exceptions. The other mechanism uses setjmp and longjmp equivalents, and + can result in quite a bit of runtime overhead. You can determine which + mechanism is the default for your target by compiling a testcase that + uses exceptions and doing an 'nm' on the object file; if it uses __throw, + it's using the first mechanism. If it uses __sjthrow, it's using the + second. + + You can turn EH support off with -fno-exceptions. + +* RTTI support has been rewritten to work properly and is now on by default. + This means code that uses virtual functions will have a modest space + overhead. You can use the -fno-rtti flag to disable RTTI support. + +* On ELF systems, duplicate copies of symbols with 'initialized common' + linkage (such as template instantiations, vtables, and extern inlines) + will now be discarded by the GNU linker, so you don't need to use -frepo. + This support requires GNU ld from binutils 2.8 or later. + +* The overload resolution code has been rewritten to conform to the latest + C++ Working Paper. Built-in operators are now considered as candidates + in operator overload resolution. Function template overloading chooses + the more specialized template, and handles base classes in type deduction + and guiding declarations properly. In this release the old code can + still be selected with -fno-ansi-overloading, although this is not + supported and will be removed in a future release. + +* Standard usage syntax for the std namespace is supported; std is treated + as an alias for global scope. General namespaces are still not supported. + +* New flags: + + + New warning -Wno-pmf-conversion (don't warn about + converting from a bound member function pointer to function + pointer). + + + A flag -Weffc++ has been added for violations of some of the style + guidelines in Scott Meyers' _Effective C++_ books. + + + -Woverloaded-virtual now warns if a virtual function in a base + class is hidden in a derived class, rather than warning about + virtual functions being overloaded (even if all of the inherited + signatures are overridden) as it did before. + + + -Wall no longer implies -W. The new warning flag, -Wsign-compare, + included in -Wall, warns about dangerous comparisons of signed and + unsigned values. Only the flag is new; it was previously part of + -W. + + + The new flag, -fno-weak, disables the use of weak symbols. + +* Synthesized methods are now emitted in any translation units that need + an out-of-line copy. They are no longer affected by #pragma interface + or #pragma implementation. + +* __FUNCTION__ and __PRETTY_FUNCTION__ are now treated as variables by the + parser; previously they were treated as string constants. So code like + `printf (__FUNCTION__ ": foo")' must be rewritten to + `printf ("%s: foo", __FUNCTION__)'. This is necessary for templates. + +* local static variables in extern inline functions will be shared between + translation units. + +* -fvtable-thunks is supported for all targets, and is the default for + Linux with glibc 2.x (also called libc 6.x). + +* bool is now always the same size as another built-in type. Previously, + a 64-bit RISC target using a 32-bit ABI would have 32-bit pointers and a + 64-bit bool. This should only affect Irix 6, which was not supported in + 2.7.2. + +* new (nothrow) is now supported. + +* Synthesized destructors are no longer made virtual just because the class + already has virtual functions, only if they override a virtual destructor + in a base class. The compiler will warn if this affects your code. + +* The g++ driver now only links against libstdc++, not libg++; it is + functionally identical to the c++ driver. + +* (void *)0 is no longer considered a null pointer constant; NULL in + is now defined as __null, a magic constant of type (void *) + normally, or (size_t) with -ansi. + +* The name of a class is now implicitly declared in its own scope; A::A + refers to A. + +* Local classes are now supported. + +* __attribute__ can now be attached to types as well as declarations. + +* The compiler no longer emits a warning if an ellipsis is used as a + function's argument list. + +* Definition of nested types outside of their containing class is now + supported. For instance: + + struct A { + struct B; + B* bp; + }; + + struct A::B { + int member; + }; + +* On the HPPA, some classes that do not define a copy constructor + will be passed and returned in memory again so that functions + returning those types can be inlined. + +*** The g++ team thanks everyone that contributed to this release, + but especially: + +* Joe Buck , the maintainer of the g++ FAQ. +* Brendan Kehoe , who coordinates testing of g++. +* Jason Merrill , the g++ maintainer. +* Mark Mitchell , who implemented member function + templates and explicit qualification of function templates. +* Mike Stump , the previous g++ maintainer, who did most of + the exception handling work. + + +Copyright (C) 1997, 1998, 1999, 2000, 2001, 2002, 2003, +2005 Free Software Foundation, Inc. + +Copying and distribution of this file, with or without modification, +are permitted in any medium without royalty provided the copyright +notice and this notice are preserved. diff --git a/gcc/cp/call.c b/gcc/cp/call.c new file mode 100644 index 000000000..50e5c5aff --- /dev/null +++ b/gcc/cp/call.c @@ -0,0 +1,8458 @@ +/* Functions related to invoking methods and overloaded functions. + Copyright (C) 1987, 1992, 1993, 1994, 1995, 1996, 1997, 1998, + 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010 + Free Software Foundation, Inc. + Contributed by Michael Tiemann (tiemann@cygnus.com) and + modified by Brendan Kehoe (brendan@cygnus.com). + +This file is part of GCC. + +GCC is free software; you can redistribute it and/or modify +it under the terms of the GNU General Public License as published by +the Free Software Foundation; either version 3, or (at your option) +any later version. + +GCC is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
