2012-05-29PR preprocessor/53229 - Fix diagnostics location when pasting tokensDodji Seketeli1-29/+1
As stated in the audit trail of this problem report, consider this test case: $ cat test.c 1 struct x { 2 int i; 3 }; 4 struct x x; 5 6 #define TEST(X) x.##X 7 8 void foo (void) 9 { 10 TEST(i) = 0; 11 } $ $ cc1 -quiet test.c test.c: In function 'foo': test.c:10:1: error: pasting "." and "i" does not give a valid preprocessing token TEST(i) = 0; ^ $ So, when pasting tokens, the error diagnostic uses the global and imprecise input_location variable, leading to an imprecise output. To properly fix this, I think libcpp should keep the token of the pasting operator '##', instead of representing it with flag on the LHS operand's token. That way, it could use its location. Doing that would be quite intrusive though. So this patch just uses the location of the LHS of the pasting operator, for now. It's IMHO better than the current situation. The patch makes paste_tokens take a location parameter that is used in the diagnostics. This change can still be useful later when we can use the location of the pasting operator, because paste_tokens will just be passed the new, more precise location. Incidentally, it appeared that when getting tokens from within preprocessor directives (like what is done in gcc.dg/cpp/paste12.c), with -ftrack-macro-expansion disabled, the location of the expansion point of macros was being lost because cpp_reader::set_invocation_location wasn't being properly set. It's because when cpp_get_token_1 calls enter_macro_context, there is a little period of time between the beginning of that later function and when the macro is really pushed (and thus when the macro is really expanded) where we wrongly consider that we are not expanding the macro because macro_of_context is still NULL. In that period of time, in the occurrences of indirect recursive calls to cpp_get_token_1, this later function wrongly sets cpp_reader::invocation_location because cpp_reader::set_invocation_location is not being properly set. To avoid that confusion the patch does away with cpp_reader::set_invocation_location and introduces a new flag cpp_reader::about_to_expand_macro_p that is set in the small time interval exposed earlier. A new in_macro_expansion_p is introduced as well, so that cpp_get_token_1 can now accurately detect when we are in the process of expanding a macro, and thus correctly collect the location of the expansion point. People seem to like screenshots. Thus, after the patch, we now have: $ cc1 -quiet test.c test.c: In function 'foo': test.c:6:18: error: pasting "." and "i" does not give a valid preprocessing token #define TEST(X) x.##X ^ test.c:10:3: note: in expansion of macro 'TEST' TEST(i) = 0; ^ $ Bootstrapped and tested on x86_64-unknown-linux-gnu against trunk. libcpp/ PR preprocessor/53229 * internal.h (cpp_reader::set_invocation_location): Remove.

2012-05-02Properly initialize cpp_context in destringize_and_runDodji Seketeli1-4/+1
destringize_and_run forgets to initialize all the fields of the cpp_context that it pushes. Later _cpp_pop_context then gets confused when it accesses context->tokens_kind via the call to macro_of_context on context->prev. The first hunk of this patch is the real obvious fix. The second hunk is just an assert that I am adding to err on the safe side. Tested by on x86_64-unknown-linux-gnu against trunk by running the test gcc.dg/gomp/macro-4.c under Valgrind, and bootstrapped. libcpp/ * directives.c (destringize_and_run): Properly initialize the new context. * macro.c (_cpp_pop_context): Assert that we shouldn't try to pop the initial base context, which has the same life time as the current instance of cpp_file.

2011-10-17Generate virtual locations for tokensTom Tromey1-2/+2
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
2011-10-17Linemap infrastructure for virtual locationsTom Tromey1-7/+9
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
