2008-03-21Only invoke the preprocessor; it's the only thing being tested. Also, checkSam Bishop
the output to make sure that the macros and comments are being treated as such. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48638 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-21Use the -E option when invoking clang. Only the preprocessor isSam Bishop
required to perform this test. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48636 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-06remove two obsolete tests, not sure why my previous commit didn't commit the ↵Chris Lattner
removal. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47986 91177308-0d34-0410-b5e6-96231b3b80d8

2008-02-16Fix CheckEndOfDirective to diagnose lines that contain macros that expand to Chris Lattner
zero tokens. This fixes PR2045, thanks to Neil for finding another incredibly subtle corner case :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47203 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-07Implement support for the extremely atrocious MS /##/ extension, Chris Lattner
which pastes together a comment. This is only enabled with -fms-extensions of course. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46845 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-29Fix a bug where we would incorrectly emit a "cannot paste" error Chris Lattner
message when handling the GNU ", ## __VA_ARGS__" extension. While I'm at it, flag uses of this as extensions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46503 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-22Fix PR1936, a crash on malformed #if. Thanks to Neil forChris Lattner
noticing this! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46256 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-07Fix a nasty corner case that Neil noticed in PR1900, where we would Chris Lattner
incorrectly apply the multiple include optimization to files with guards like: #if !defined(x) MACRO where MACRO could expand to different things in different contexts. Thanks Neil! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45716 91177308-0d34-0410-b5e6-96231b3b80d8

2007-12-09The flags on tokens indicate whether they are the start of a *physical* line, Chris Lattner
not the start of a logical line. Be careful about this distinction, which affects when newlines are printed and when paste-avoidance happens, etc. This fixes PR1848, thanks to Neil for noticing this! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44743 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-23Fix PR1820, an incredibly subtle macro expansion bug that Neil discovered.Chris Lattner
Neil, please review this fix. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44285 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-15fix a bug Steve noticed, where a #import of the main file itself would fail.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44178 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-24If we see an invalid #ifdef directive, enter a conditional compilation regionChris Lattner
so that we don't emit an error on the #endif. Suggestion by Neil. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42258 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-23implement a missing feature in the #include handler, whereChris Lattner
it did not handle <xyz> headers coming from macro expansions. This requires special treatment, as the include name is lexed as multiple tokens, which require reassembly before processing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40418 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-19Fix a stringizing bug that Neil noticed. We should preprocess this:Chris Lattner
#define t(x) #x t(a c) to "a c", not "ac". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40060 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-19Correctly respect C99 5.1.1.2p4 when searching for the first '(' ofChris Lattner
a function-like macro invocation. Patch contributed by Neil Booth. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40026 91177308-0d34-0410-b5e6-96231b3b80d8
