backport: As described in http://gcc.gnu.org/ml/gcc/2012-08/msg00015.html... Merge from cxx-conversion branch (http://gcc.gnu.org/wiki/cxx-conversion). As described in http://gcc.gnu.org/ml/gcc/2012-08/msg00015.html, this patch changes the default bootstrap process so that stage 1 always builds with a C++ compiler. Other than the bootstrap change, the patch makes no functional changes to the compiler. Everything should build as it does now in trunk. The main changes in this patch are: 1- Configuration changes. 2- Re-write of VEC. 3- Re-write of gengtype to support C++ templates and user-provided marking functions. 4- New hash table class. 5- Re-write double_int. 6- Implement tree macros as inline functions so they can be called from gdb. As discussed before, several of these changes do not fully change the call sites to use the new APIs. The bootstrap changes have already been tested on a wide range of targets (http://gcc.gnu.org/wiki/CppBuildStatus). Additionally, I have tested the merged trunk on: x86_64-unknown-linux-gnu, mips64el-unknown-linux-gnu, powerpc64-unknown-linux-gnu, i686-pc-linux-gnu, and ia64-unknown-linux-gnu.

Generate virtual locations for tokens This second instalment uses the infrastructure of the previous patch to allocate a macro map for each macro expansion and assign a virtual location to each token resulting from the expansion. To date when cpp_get_token comes across a token that happens to be a macro, the macro expander kicks in, expands the macro, pushes the resulting tokens onto a "token context" and returns a dummy padding token. The next call to cpp_get_token goes look into the token context for the next token [which is going to result from the previous macro expansion] and returns it. If the token is a macro, the macro expander kicks in and you know the story. This patch piggy-backs on that macro expansion process, so to speak. First it modifies the macro expander to make it create a macro map for each macro expansion. It then allocates a virtual location for each resulting token. Virtual locations of tokens resulting from macro expansions are then stored on a special kind of context called an "expanded tokens context". In other words, in an expanded tokens context, there are tokens resulting from macro expansion and their associated virtual locations. cpp_get_token_with_location is modified to return the virtual location of tokens resulting from macro expansion. Note that once all tokens from an expanded token context have been consumed and the context and is freed, the memory used to store the virtual locations of the tokens held in that context is freed as well. This helps reducing the overall peak memory consumption. The client code that was getting macro expansion point location from cpp_get_token_with_location now gets virtual location from it. Those virtual locations can in turn be resolved into the different interesting physical locations thanks to the linemap API exposed by the previous patch. Expensive progress. Possibly. So this whole virtual location allocation business is switched off by default. So by default no extended token is created. No extended token context is created either. One has to use -ftrack-macro-expansion to switch this on. This complicates the code but I believe it can be useful as some of our friends found out at http://llvm.org/bugs/show_bug.cgi?id=5610 The patch tries to reduce the memory consumption by freeing some token context memory that was being reused before. I didn't notice any compilation slow down due to this immediate freeing on my GNU/Linux system. As no client code tries to resolve virtual locations to anything but what was being done before, no new test case has been added. Co-Authored-By: Dodji Seketeli <dodji@redhat.com> From-SVN: r180082

Generate virtual locations for tokens This second instalment uses the infrastructure of the previous patch to allocate a macro map for each macro expansion and assign a virtual location to each token resulting from the expansion. To date when cpp_get_token comes across a token that happens to be a macro, the macro expander kicks in, expands the macro, pushes the resulting tokens onto a "token context" and returns a dummy padding token. The next call to cpp_get_token goes look into the token context for the next token [which is going to result from the previous macro expansion] and returns it. If the token is a macro, the macro expander kicks in and you know the story. This patch piggy-backs on that macro expansion process, so to speak. First it modifies the macro expander to make it create a macro map for each macro expansion. It then allocates a virtual location for each resulting token. Virtual locations of tokens resulting from macro expansions are then stored on a special kind of context called an "expanded tokens context". In other words, in an expanded tokens context, there are tokens resulting from macro expansion and their associated virtual locations. cpp_get_token_with_location is modified to return the virtual location of tokens resulting from macro expansion. Note that once all tokens from an expanded token context have been consumed and the context and is freed, the memory used to store the virtual locations of the tokens held in that context is freed as well. This helps reducing the overall peak memory consumption. The client code that was getting macro expansion point location from cpp_get_token_with_location now gets virtual location from it. Those virtual locations can in turn be resolved into the different interesting physical locations thanks to the linemap API exposed by the previous patch. Expensive progress. Possibly. So this whole virtual location allocation business is switched off by default. So by default no extended token is created. No extended token context is created either. One has to use -ftrack-macro-expansion to switch this on. This complicates the code but I believe it can be useful as some of our friends found out at http://llvm.org/bugs/show_bug.cgi?id=5610 The patch tries to reduce the memory consumption by freeing some token context memory that was being reused before. I didn't notice any compilation slow down due to this immediate freeing on my GNU/Linux system. As no client code tries to resolve virtual locations to anything but what was being done before, no new test case has been added. Co-Authored-By: Dodji Seketeli <dodji@redhat.com> From-SVN: r180082

/* This structure defines one built-in identifier. A node will be
entered in the hash table under the name NAME, with value VALUE.
There are two tables of these. builtin_array holds all the
"builtin" macros: these are handled by builtin_macro() in
macro.c. Builtin is somewhat of a misnomer -- the property of
interest is that these macros require special code to compute their
expansions. The value is a "cpp_builtin_type" enumerator.
operator_array holds the C++ named operators. These are keywords
which act as aliases for punctuators. In C++, they cannot be
altered through #define, and #if recognizes them as operators. In
C, these are not entered into the hash table at all (but see
<iso646.h>). The value is a token-type enumerator. */

Linemap infrastructure for virtual locations This is the first instalment of a set which goal is to track locations of tokens across macro expansions. Tom Tromey did the original work and attached the patch to PR preprocessor/7263. This opus is a derivative of that original work. This patch modifies the linemap module of libcpp to add virtual locations support. A virtual location is a mapped location that can resolve to several different physical locations. It can always resolve to the spelling location of a token. For tokens resulting from macro expansion it can resolve to: - either the location of the expansion point of the macro. - or the location of the token in the definition of the macro - or, if the token is an argument of a function-like macro, the location of the use of the matching macro parameter in the definition of the macro The patch creates a new type of line map called a macro map. For every single macro expansion, there is a macro map that generates a virtual location for every single resulting token of the expansion. The good old type of line map we all know is now called an ordinary map. That one still encodes spelling locations as it has always had. As a result linemap_lookup as been extended to return a macro map when given a virtual location resulting from a macro expansion. The layout of structs line_map has changed to support this new type of map. So did the layout of struct line_maps. Accessor macros have been introduced to avoid messing with the implementation details of these datastructures directly. This helped already as we have been testing different ways of arranging these datastructure. Having to constantly adjust client code that is too tied with the internals of line_map and line_maps would have been even more painful. Of course, many new public functions have been added to the linemap module to handle the resolution of virtual locations. This patch introduces the infrastructure but no part of the compiler uses virtual locations yet. However the client code of the linemap data structures has been adjusted as per the changes. E.g, it's not anymore reliable for a client code to manipulate struct line_map directly if it just wants to deal with spelling locations, because struct line_map can now represent a macro map as well. In that case, it's better to use the convenient API to resolve the initial (possibly virtual) location to a spelling location (or to an ordinary map) and use that. This is the reason why the patch adjusts the Java, Ada and Fortran front ends. Also, note that virtual locations are not supposed to be ordered for relations '<' and '>' anymore. To test if a virtual location appears "before" another one, one has to use a new operator exposed by the line map interface. The patch updates the only spot (in the diagnostics module) I have found that was making the assumption that locations were ordered for these relations. This is the only change that introduces a use of the new line map API in this patch, so I am adding a regression test for it only. From-SVN: r180081
