targets when Altivec is enabled. 2014-10-03 Bill Schmidt <wschmidt@linux.vnet.ibm.com> * lex.c (search_line_fast): Add new version to be used for Power8 and later targets when Altivec is enabled. Restrict the existing Altivec version to big-endian systems so that lvsr is not used on little endian, where it is deprecated. Remove LE-specific code from the now-BE-only version. From-SVN: r215873

2012-04-27Add new option, -Wliteral-suffix.Ollie Wild1-6/+38
This option, which is enabled by default, causes the preprocessor to warn when a string or character literal is followed by a ud-suffix which does not begin with an underscore. According to [lex.ext]p10, this is ill-formed. Also modifies the preprocessor to treat such ill-formed suffixes as separate preprocessing tokens. This is consistent with the Clang front end (see http://llvm.org/viewvc/llvm-project?view=rev&revision=152287), and enables backwards compatibility with code that uses formatting macros from <inttypes.h>, as in the following code block: int main() { int64_t i64 = 123; printf("My int64: %"PRId64"\n", i64); } Google ref b/6377711. 2012-04-27 Ollie Wild <aaw@google.com> PR c++/52538 * gcc/c-family/c-common.c: Add CPP_W_LITERAL_SUFFIX mapping. * gcc/c-family/c-opts.c (c_common_handle_option): Handle OPT_Wliteral_suffix. * gcc/c-family/c.opt: Add Wliteral-suffix. * gcc/doc/invoke.texi (Wliteral-suffix): Document new option. * gcc/testsuite/g++.dg/cpp0x/Wliteral-suffix.c: New test. * libcpp/include/cpplib.h (struct cpp_options): Add new field, warn_literal_suffix.

2011-10-17Generate virtual locations for tokensTom Tromey1-7/+34
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
