Rafael Espindola 0ddfbe230f We already have support for using c++ headers from a custom location.
Before this patch we would still link with the system libstdc++. It worked
fine most of the time, but would break if the used headers were a lot newer
than the system libraries.

This patch changes the driver to use the libraries corresponding to the
headers the user selected.

This fixes, for example, using 4.5 headers in a system with gcc 4.1.

Joerg Sonnenberger 637603a7cc Make the triple an explicit argument of FindTargetProgramPath.
Preserve the original triple in the NetBSD toolchain when using -m32 or
-m64 and the resulting effective target is different from the triple it
started with. This allows -m32 to use the same assembler/linking in
cross-compiling mode and avoids confusion about passing down target
specific flags in that case like --32.

Chandler Carruth 30483fb188 Move all of the logic for __DEPRECATED to the driver based on comments
from dgregor.

llvm-svn: 130066
2011-04-23 19:48:40 +00:00
Chandler Carruth 61fbf62838 Fix Clang's __DEPRECATED define to be controled by -Wdeprecated. This
matches GCC behavior which libstdc++ uses to limit #warning-based
messages about deprecation.

The machinery involves threading this through a new '-fdeprecated-macro'
flag for CC1. The flag defaults to "on", similarly to -Wdeprecated. We
turn the flag off in the driver when the warning is turned off (modulo
matching some GCC bugs). We record this as a language option, and key
the preprocessor on the option when introducing the define.

A separate flag rather than a '-D' flag allows us to properly represent
the difference between C and C++ builds (only C++ receives the define),
and it allows the specific behavior of following -Wdeprecated without
potentially impacting the set of user-provided macro flags.

llvm-svn: 130055
2011-04-23 09:27:53 +00:00
Chandler Carruth b009b14971 There were some frustrating problems with the implementation of
-Wwrite-strings. First and foremost, once the positive form of the flag
was passed, it could never be disabled by passing -Wno-write-strings.
Also, the diagnostic engine couldn't in turn use -Wwrite-strings to
control diagnostics (as GCC does) because it was essentially hijacked to
drive the language semantics.

Fix this by giving CC1 a clean '-fconst-strings' flag to enable
const-qualified strings in C and ObjC compilations. Corresponding
'-fno-const-strings' is also added. Then the driver is taught to
introduce '-fconst-strings' in the CC1 command when '-Wwrite-strings'
dominates.

This entire flag is basically GCC-bug-compatibility driven, so we also
match GCC's bug where '-w' doesn't actually disable -Wwrite-strings. I'm
open to changing this though as it seems insane.

Francois Pichet 1c229c0472 Add -fdelayed-template-parsing option. Using this option all templated function definitions are parsed at the end of the translation unit only if it is required by an actual instantiation. As such all the symbols of the TU are available during name lookup.
Using this flag is necessary for compatibility with Microsoft template code.
This also provides some parsing speed improvement.

Chandler Carruth b6766f07c8 Add an option to suppress include stack printing on note diagnostics.
These stacks are often less important than those on primary diagnostics.

As the number of notes grows, this becomes increasingly important. The
include stack printing is clever and doesn't print stacks for adjacent
diagnostics from the same file, but when a note is in between a sequence
of errors in a header file, and the notes all refer to some other file,
we end up getting a worst-case ping-pong of include stacks that take up
a great deal of vertical space.

Still, for now, the default behavior isn't changed. We can evaluate user
feedback with the flag.

Patch by Richard Trieu, a couple of style tweaks from me.

Benjamin Kramer 51477bd0d0 Since getDriver().getInstalledDir() returns a const char *, don't try to
compare it with getDriver().Dir.c_str(), since that is a pointer
comparison, not a "are these strings equal" comparison.

Instead, just compare with getDriver().Dir directly, so both sides will
get promoted to std::string, and the regular std::string comparison
operator applies.

it is *not* supposed to use /usr/local/lib by default, for example.

Additionally, there are no clang-related executables in either
/usr/libexec, or getDriver().Dir + "/../libexec", anymore, so remove
that from the ToolChain's ProgramPaths.

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.

Rafael Espindola c8f008f649 Use ld directly on linux. Changes from the previous try:
*) Try to detect as much as possible from the system itself, not the distro.
   This should make it easier to port to a new distro and more likely to
   work on a unknown one.
*) The distro enum now doesn't include the arch. Just use the existing
   host detection support in LLVM.
*) Correctly handle --sysroot.

A small regression is that now clang will pass bitcode file to the linker.
This is necessary for the gold plugin support to work.

It might be better to detect this at configure/cmake time, but doing it in
c++ first is a lot easier.

Argyrios Kyrtzidis 71731d6b05 Implement -working-directory.
When -working-directory is passed in command line, file paths are resolved relative to the specified directory.
This helps both when using libclang (where we can't require the user to actually change the working directory)
and to help reproduce test cases when the reproduction work comes along.

--FileSystemOptions is introduced which controls how file system operations are performed (currently it just contains
 the working directory value if set).
--FileSystemOptions are passed around to various interfaces that perform file operations.
--Opening & reading the content of files should be done only through FileManager. This is useful in general since
 file operations will be abstracted in the future for the reproduction mechanism.

FileSystemOptions is independent of FileManager so that we can have multiple translation units sharing the same
FileManager but with different FileSystemOptions.

Addresses rdar://8583824.

g++ main.o -o main
gcc main.o -o main -static
g++ main.o -o main -static
gcc f.o -o f.so -shared
g++ f.o -o f.so -shared

and comparing the ld line with the one created by clang. I also added
-m32/m64 in distros that support it.

While I tested many distros, there will always be more. If you are hit by this
it should be somewhat easy to add your distro. If you are in a hurry, do
revert this, but please inform how to detect you distro and the ld command
lines produced by the above gcc invocations. Most distros have some patches
on gcc :-(

Daniel Dunbar 8fa86b1a44 Driver/DarwinClang: The new toolchain definition is going to drop the -L inside
the GCC dir. Unfortunately, this breaks -lstdc++ on SnowLeopard, etc. because
the libstdc++ dylib was hiding there. Workaround this by providing the path to
the right -lstdc++.6 (the only version used in recent memory) if we can't see an
obvious -lstdc++, but can find = -lstdc++.6.

2010-09-17 01:16:06 +00:00
Daniel Dunbar 2cc3f17a26 Driver: Add magic handling for "reserved library names", starting with
-lstdc++. This is the best gross solution for a gross problem.

This issue is that historically, GCC has add -L options to its internally
library directories. This has allowed users and platforms to end up depending on
the layout of GCC's internal library directories.

We want to correct this mistake by eliminating that -L, but this means that
existing libraries which are in the GCC lib dir won't be found. We are going to
handle this by treating those -l names as "reserved", and requiring toolchains
to know how to add the right full path to the reserved library.

The immediately side effect of this is that users trying to use -L to find their
own -lstdc++ will need to start using -nostdlib (which is a good idea
anyway). Another side effect is that -stdlib=libc++ -lstdc++ will now do the
"right" thing, for curious definitions of right.

Daniel Dunbar 3d7e0e2c6b Driver/Darwin: Catch another case where ld ends up using ld_classic.

2010-09-07 17:50:41 +00:00
Daniel Dunbar 1eaf5c6abb Driver/Darwin: Don't pass -demangle to the linker when we know it is going to
use ld_classic. This is a temporary workaround, the linkr itself should handle
this.

Rafael Espindola b2d0d40c3d Make "-ccc-cxx" option work on Linux.
Patch by nobled.

I also took the opportunity to make the field private since now it is only ready from the
outside.

Dawn Perchik 68bb1b441f Add support for Borland extensions via option -fborland-extensions
(original patch r112791 was reverted due to a bug).

Dawn Perchik f0882f90f3 Reverting rev 112791 - apparently -fborland-extensions is on all the time?!

Daniel Dunbar f241019e24 Driver/Darwin: Switch back to old toolchain, looks like new one isn't quite
ready yet.

llvm-svn: 112138
2010-08-26 01:41:44 +00:00
Daniel Dunbar b8f7a14575 Driver: Fix thinko where I switched to always using the old toolchain, instead
of always using the new toolchain.

Daniel Dunbar e9f7151485 Driver/Darwin: Pass the right arch specific dir for ARM, when linking.
llvm-svn: 112124
2010-08-26 00:55:52 +00:00
Daniel Dunbar d435275c59 Frontend: Add basic -H support.
- I didn't implement the GCC "multiple include guard" detection parts, because
   it doesn't seem useful or obvious.

Daniel Dunbar fe6c97b443 Driver/Clang: Forward -Wa, and -Xassembler to clang -cc1 when using the
integrated assembler. For now this mostly just means that we will error out if
someone tries to use this mechanism to send an argument to the assembler.

Daniel Dunbar 82eb4ce476 Driver: Move Clang "triple" computation routines to method on the
ToolChain. This fixes a potenial bad cast when running Clang on PPC code, since
the tool chain in effect is not a subclass of the Darwin one, but we were
treating it like it was.
 - This introduces some gross code duplication, but the right fix for it is to
   just move the Driver to start depending on the targets in libBasic, so I am
   not planning on fixing it immediately.

2010-08-23 22:35:37 +00:00
Daniel Dunbar e31e323c02 Driver/Darwin: Switch to using simplified tool chain by default -- what better
way to see what will break! :)

llvm-svn: 111840
2010-08-23 20:58:55 +00:00
Daniel Dunbar 09a4851ead Driver/Darwin: When using the simplified Clang toolchain, make sure to also pass
the arch specific gcc lib path.

llvm-svn: 111839
2010-08-23 20:58:52 +00:00
Daniel Dunbar 5d3b70a6fc Driver: Update -ccc-install-dir to also set the installed dir. Totally
non-obvious.

Chandler Carruth 6f33bd9345 Add two new enumerations to the unsupported list for Windows so that all cases

Daniel Dunbar b613ffc1aa Driver: Claim the -mlinker-version synthesized argument, it shouldn't be
reported as unused.

David Chisnall 589a494352 Pass some things to the linker that gcc passes. -r is the only one of these that I'm sure about, but the others seem to be listed on FreeBSD by gcc -dumpspecs, so I hope they're right. Apparently -r is also not passed on GNU/Linux (and should be), but I can't see where the toolchain definition for this platform live.

2010-08-15 22:58:12 +00:00
Daniel Dunbar 568b7500fe Driver/OptParser: Add a NoForward flag to prevent forwarding certain options to
GCC.
 - Mark -Xclang and -mlinker-version= with it for now, although I am sure there
   are more.

llvm-svn: 111005
2010-08-13 04:44:20 +00:00
Daniel Dunbar 628fcf4e3b Driver: Use the compile time linker version as the default for -mlinker-version,
if detected.
 - This is a hack, we really want the linker version at execution time, but we
   don't have any infrastructure for getting that. Yet.

Daniel Dunbar cacb0e2d45 Driver/Darwin: Pass -demangle when linking, if the linker supports it.
llvm-svn: 110873
2010-08-11 23:07:50 +00:00
Daniel Dunbar 976a2f54fa Driver: Add -mlinker-version=, which forwards to -target-linker-version.

Daniel Dunbar ce25f33e2a Driver/FreeBSD: Infer the right arch name in the presence of -m32,-m64, for the
cases we care about.
 - This is eventually going to be unified outside the host specific code.
