Joerg Sonnenberger fcc3ec90a5 Introduce FindTargetProgramPath to check for a target-specific helper 
program and fallback to plain version otherwise. Use this for the NetBSD
target to make it try e.g. i486--netbsdelf-as and -ld for target
i486--netbsdelf.

Joerg Sonnenberger 6165ab1132 Remember sysroot in Driver. Pass it down to ld for NetBSD, FreeBSD 
and DragonFly. Use the --sysroot= form for Linux. Fix handling of =
prefix for -B.

Daniel Dunbar 8c3d735118 Driver: Forward -traditional and -traditional-cpp in preprocessing modes. 
- We don't really support the majority of the horrible -traditional-cpp
   behavior, but it is unlikely that we ever will either. This allows us to
   start trying to use clang as a /usr/bin/cpp replacement and see what pieces
   of -traditional-cpp mode people actually care about.

John McCall 7ef5cb3038 The Darwin kernel does not provide useful guard variable support. 
Issue this as an IR-gen error;  it's not really worthwhile doing this
"right", i.e. in Sema, because IR gen knows a lot of tricks beyond
what the constant evaluator knows.

Daniel Dunbar c44f8cf7b8 Driver/Obj-C: Be compatible with GCC behavior in that -fno-exceptions *does not* 
disable Obj-C exceptions.

llvm-svn: 127836

Daniel Dunbar 033a4bc49e Driver/Darwin: These are command line options, not target features.

Daniel Dunbar 1d733e2d7e Driver/Darwin: Suppress spurious warning about -force_cpusubtype_ALL.

Daniel Dunbar c9388c11f1 Driver/Darwin/ARM: Kernel/kext code has more strict alignment requirements.

Daniel Dunbar b1db4b69cc Driver/ARM: Match GCC behavior in that -msoft-float disables NEON, despite this 
not being consistent at all with other parts of the GCC implementation.

Ted Kremenek a4a57c10da Re-enable the IdempotentOperations checker for --analyze, and put it and the DeadStores checker into the "deadcode" group.

Joerg Sonnenberger b86f5f4106 If called as *cpp or *cpp-[^-]*, run only the preprocessor. If no 
input is specified, use stdin implicitly. Based on a patch from
Roman Divacky.

Roman Divacky 432f10df68 The default CPU on FreeBSD for i386 should be i486, not pentium4.

Roman Divacky ee8188a23b For linking on FreeBSD, don't add a hardcoded "-L/usr/lib", but 
retrieve the library paths from the ToolChain object instead.

Copy the relevant code from linuxtools::Link::ConstructJob(), and
replace the std::string stuff with llvm::StringRef, while we're here.

Rafael Espindola d95a81293b Disable more warnings so that it is safe to use 
CC="clang -use-gold-plugin -emit-llvm"
CXX="clang++ -use-gold-plugin -emit-llvm"

llvm-svn: 126740
 2011-03-01 05:25:27 +00:00
Rafael Espindola 22f60303f2 Don't warn about "clang -use-gold-plugin -c ...". With this users can say 
CC="clang -use-gold-plugin" CFLAGS=-emit-llvm ../configure...
and not be hit with a warning for each .c file.

Argyrios Kyrtzidis 9eb02dfa89 [analyzer] Remove '-analyzer-check-objc-mem' flag, the nominee for best misnomer award. 
llvm-svn: 126676
 2011-02-28 19:49:42 +00:00
David Chisnall da20991a1b Make -fobjc-nonfragile-abi and -fgnu-runtime imply -fblocks (unless -fno-blocks is specified), because this combination of flags defines an Objective-C runtime that includes a blocks runtime. 
llvm-svn: 126654
 2011-02-28 17:11:43 +00:00
Chandler Carruth 74f8711802 Fix a tiny goof in the Driver's logic which caused the explicit presence 
of -fexceptions to disably C++ exceptions. The correct code was in the
ObjC branch, this just mirrors that logic on the C++ side of things.
Thanks to John Wiegley for pointing this out.

llvm-svn: 126640
 2011-02-28 07:25:18 +00:00
Anders Carlsson e96ab55b28 Add a -fcxx-exceptions flag to the frontend, which can be used to enable 
C++ exceptions, even when exceptions have been turned off using -fno-exceptions.
Make the -fobjc-exceptions flag do the same thing, but for Objective-C exceptions.

C++ and Objective-C exceptions can also be disabled using -fno-cxx-excptions and
-fno-objc-exceptions.

Argyrios Kyrtzidis 3e7ab19863 [analyzer] Move the DeadStores checker out of the 'core' package. 
-Now it gets enabled with '-analyzer-checker=DeadStores'.
-The driver passes the above flag by default.

llvm-svn: 126612

Anders Carlsson 246ff3f19f Factor code out into a helper function, shouldUseExceptionTablesForObjCExceptions. 
llvm-svn: 126601
 2011-02-28 00:44:51 +00:00
Anders Carlsson 3320e1575f Make clang -cc1 disable Objective-C exceptions by default, and add a -fobjc-exceptions flag to turn them on. 
Update all tests accordingly.

llvm-svn: 126133
 2011-02-21 18:36:51 +00:00
Anders Carlsson ce8dd3a5d4 Add a new ObjCExceptions member variable to LangOptions. This controls whether Objective-C exceptions are enabled or not (they are by default). 
llvm-svn: 126061
 2011-02-19 23:53:54 +00:00
Argyrios Kyrtzidis 3b1b3fe039 [analyzer] '-analyzer-check-objc-mem' can go through the llvm/clang codebase without crashing; enable it for C++. 
llvm-svn: 126026
 2011-02-19 08:03:21 +00:00
Daniel Dunbar 1094bb101b Driver/Darwin: Support -Wl, with -Xarch_. This doesn't work naturally because of 
the special way we model "linker input" arguments.

Argyrios Kyrtzidis af45aca670 [analyzer] Use the new registration mechanism on the non-path-sensitive-checkers: 
DeadStoresChecker
  ObjCMethSigsChecker
  ObjCUnusedIvarsChecker
  SizeofPointerChecker
  ObjCDeallocChecker
  SecuritySyntaxChecker

NAKAMURA Takumi 31ea2f14bc Triple::MinGW64 is deprecated and removed. We can use Triple::MinGW32 instead. 
No one uses *-mingw64. mingw-w64 is represented as {i686|x86_64}-w64-mingw32.

llvm-svn: 125611
 2011-02-15 22:55:14 +00:00
Argyrios Kyrtzidis a6d04d541d [analyzer] Use the new registration mechanism on some of the internal checks. These are: 
StackAddrLeakChecker
ObjCAtSyncChecker
UnixAPIChecker
MacOSXAPIChecker

The rest have/create implicit dependencies between checkers and need to be handled differently.

llvm-svn: 125559
 2011-02-15 07:42:33 +00:00
Argyrios Kyrtzidis 556c45e9c5 [analyzer] Overhauling of the checker registration mechanism. 
-Checkers will be defined in the tablegen file 'Checkers.td'.
-Apart from checkers, we can define checker "packages" that will contain a collection of checkers.
-Checkers can be enabled with -analyzer-checker=<name> and disabled with -analyzer-disable-checker=<name> e.g:
	Enable checkers from 'cocoa' and 'corefoundation' packages except the self-initialization checker:
	-analyzer-checker=cocoa -analyzer-checker=corefoundation -analyzer-disable-checker=cocoa.SelfInit
-Introduces CheckerManager and CheckerProvider. CheckerProviders get the set of checker names to enable/disable and
 register them with the CheckerManager which will be the entry point for all checker-related functionality.

Currently only the self-initialization checker takes advantage of the new mechanism.

 2011-02-04 02:20:39 +00:00
Daniel Dunbar ac540b3859 clang: Add support for a CC_PRINT_HEADERS environment variable, which mirrors 
CC_PRINT_OPTIONS and can be used to get some out-of-band information on header
usage from a build.

Roman Divacky 115f0fa397 Add hardcoded -L/usr/lib after all -L options to the FreeBSD linker 
invocation. 

This mimics what gcc does and fixes libtool check for libraries.

llvm-svn: 124558
 2011-01-30 08:12:24 +00:00
Argyrios Kyrtzidis c7ffd35cb7 [analyzer] Enable the self-init checker under command-line option '-analyzer-check-objc-self-init' which by default

 2011-01-26 01:26:50 +00:00
Chris Lattner 906bb9047a improve compatibility with GCC: when generating the ".d" filename to use 
and the filename has multiple .'s in it, use the last.  For example, "foo.bar.cpp"
should produce "foo.bar.d" not "foo.d".  Patch by Johan Boule in PR8391
