2009-03-03implement support for propagating *features* down to the code generatorChris Lattner
and defining target-specific macros based on them (like __SSE3__ and friends). After extensive discussion with Daniel, this work will need driver support, which will translate things like -msse3 into a -mattr feature. Until this work is done, the code in clang.cpp is disabled and the X86TargetInfo ctor still defaults to SSE2. With these two things changed, this code will work. PR3634 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65966 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-02Add plumbing to support programatically defining __SSE2__ and friends,Chris Lattner
even though we still hard code sse2 for now. No support for 3dnow or sse4a, but someone could add that if they desired. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65886 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-27Clean up and document code modification hints.Douglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65641 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-26Introduce code modification hints into the diagnostics system. When weDouglas Gregor
know how to recover from an error, we can attach a hint to the diagnostic that states how to modify the code, which can be one of: - Insert some new code (a text string) at a particular source location - Remove the code within a given range - Replace the code within a given range with some new code (a text string) Right now, we use these hints to annotate diagnostic information. For example, if one uses the '>>' in a template argument in C++98, as in this code: template<int I> class B { }; B<1000 >> 2> *b1; we'll warn that the behavior will change in C++0x. The fix is to insert parenthese, so we use code insertion annotations to illustrate where the parentheses go: test.cpp:10:10: warning: use of right-shift operator ('>>') in template argument will require parentheses in C++0x B<1000 >> 2> *b1; ^ ( ) Use of these annotations is partially implemented for HTML diagnostics, but it's not (yet) producing valid HTML, which may be related to PR2386, so it has been #if 0'd out. In this future, we could consider hooking this mechanism up to the rewriter to actually try to fix these problems during compilation (or, after a compilation whose only errors have fixes). For now, however, I suggest that we use these code modification hints whenever we can, so that we get better diagnostics now and will have better coverage when we find better ways to use this information. This also fixes PR3410 by placing the complaint about missing tokens just after the previous token (rather than at the location of the next token). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65570 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-19Fix a long standard problem with clang retaining "too much" sugar Chris Lattner
information about types. We often print diagnostics where we say "foo_t" is bad, but the user doesn't know how foo_t is declared (because it is a typedef). Fix this by expanding sugar when present in a diagnostic (and not one of a few special cases, like vectors). Before: t.m:5:2: error: invalid operands to binary expression ('typeof(P)' and 'typeof(F)') MAX(P, F); ^~~~~~~~~ t.m:1:78: note: instantiated from: #define MAX(A,B) ({ __typeof__(A) __a = (A); __typeof__(B) __b = (B); __a < __b ? __b : __a; }) ^ After: t.m:5:2: error: invalid operands to binary expression ('typeof(P)' (aka 'struct mystruct') and 'typeof(F)' (aka 'float')) MAX(P, F); ^~~~~~~~~ t.m:1:78: note: instantiated from: #define MAX(A,B) ({ __typeof__(A) __a = (A); __typeof__(B) __b = (B); __a < __b ? __b : __a; }) ^ git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65081 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-17fix notes so that they are always filtered with the same logic Chris Lattner
as the last non-note diagnostic that preceeded them. This ensures that diagnostics in main files which have notes with locations in system headers get all the bits and pieces emitted or not in a unit.

2009-02-15track "just a little more" location information for macro instantiations.Chris Lattner
Now instead of just tracking the expansion history, also track the full range of the macro that got replaced. For object-like macros, this doesn't change anything. For _Pragma and function-like macros, this means we track the locations of the ')'. This is required for PR3579 because apparently GCC uses the line of the ')' of a function-like macro as the location to expand __LINE__ to. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64601 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-12Add lightweight shim "clang::StatSysCallCache" that caches 'stat' system callsTed Kremenek
for use by FileManager. FileManager now takes a StatSysCallCache* in its constructor (which defaults to NULL). This will be used for evaluating whether or not caching 'stat' system calls in PTH is a performance win. This shim adds no observable performance impact in the case where the 'StatSysCallCache*' is null. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64345 91177308-0d34-0410-b5e6-96231b3b80d8
