Dan Gohman 04f8720118 Add several more predefines from modern versions of GCC.

Ted Kremenek 34ddec630c Predefine the '__clang_analyzer__' macro when using '-analyze'.

Douglas Gregor 6602c25c0c Add Clang version inspection macros. Fixes PR6681.

Chris Lattner 678eaa90ab fix PR6936: don't generate line marker directives when preprocessing 
.S files.  "# 123" is passed through as-is, not treated as a line
marker in this mode.  No testcase, because it would be nasty and isn't
worth it.

Douglas Gregor 3ecc665505 Sink the _GNU_SOURCE definition down into the target configuration, 
and only define it where we know we need it---Linux and Cygwin. Thanks
to Chris for the prodding.

Douglas Gregor d2b896ab69 Only predefine the macro _GNU_SOURCE in C++ mode when we're on a 
platform that typically uses glibc. Fixes a Boost.Thread compilation
failure.

Douglas Gregor 89a56c561f When given unsaved files in clang_createTranslationUnitFromSourceFile, 
copy the source buffers provided rather than referencing them
directly, so that the caller can free those buffers immediately after
calling clang_createTranslationUnitFromSourceFile(). Otherwise, we
risk hitting those buffers later (when building source ranges, forming
diagnostics, etc.).

Daniel Dunbar 3241d400c8 Switch to using -fsjlj-exceptions instead of hard-coding it. Notably, this fixes 
calls to the UnwindResumeOrRethrow function for C++/Obj-C exception handling,
for Darwin ARM.

Comments and/or improvements to the documentation are welcome.

Daniel Dunbar 415763612a Fix an invalid Twine use spotty by abbeyj, it isn't safe to use Twine 
temporaries (this is one reason I'm nervous about propagating their use beyond
particularly performance critical places).

Benjamin Kramer 2d6fda3205 Use MacroBuilder for TargetDefines instead of std::vector.

 2010-01-09 17:43:21 +00:00
Benjamin Kramer f65e959035 Rework InitPreprocessor to use a MacroBuilder class instead of pushing around 
std::vectors.

- MacroBuilder wraps a raw_ostream so it can easily write to any buffer
  supported by raw_ostream.
- MacroBuilder's method take Twines for easy string concatenation (this was done
  with sprintf and temporary buffers before).
- Targets still use std::vector as they don't have access to the builder.

Douglas Gregor 407e2124bf Extend -remap-file=from;to to permit mapping from a non-existent 
file. This is accomplished by introducing the notion of a "virtual"
file into the file manager, which provides a FileEntry* for a named
file whose size and modification time are known but which may not
exist on disk.

Added a cute little test that remaps both a .c file and a .h file it
includes to alternative files.

Rafael Espindola f8a04a1d6e Exit the command line into <built-in> instead of going directly from the command line to the input file. 
We passed <built-in> on the way in, so we should pass it again on the way out.

Chris Lattner 55c9877b66 Generalize stdint.h for non-8-bit-multiple types, patch by 
Ken Dyck!

"This adds definitions for types of 8-bit multiples
from 8 to 64 to stdint.h and rationalizes the selection of types 
for the exact-width definitions in InitPreprocessor.cpp."

llvm-svn: 86977

Chris Lattner 0fb5bbd401 do not store wchar/char16/char32/intmax width/alignment info 
into TargetInfo, just derive this based on the underlying type.
This prevents them from getting out of synch, patch by Ken Dyck!
