Saleem Abdulrasool a4a474b859 Driver: add a cygwin linker tool
This adds a linker tool for the Windows cygwin environment.  This linker
invocation is significantly different from the generic ld invocation.  It
requires additional parameters as well as does not accept some normal
parameters.  This should fix self-hosting on Cygwin.

Saleem Abdulrasool 4b68a05f3d Driver: use GNU::Link for the Generic_GCC toolchain
This changes the behaviour of the driver for linking to match that of the
Generic_GCC::Assemble.    The default link should use "ld" rather than "gcc" for
the linker as gcc does.  This avoids the unnecessary round-tripping through gcc.
It also is much more reasonable behaviour from the user's perspective.  This
should have been updated with SVN r195554 which changed the behaviour of
Generic_GCC::Assemble.

The gcc_forward test needs to be updated to mark the fact that -march is a flag
for GCC not ld.  This was updated as a typo fix, but added a check for a flag
that is not a link flag.

The bindings test covers the change for testing, and thus no new test was added.

Logan Chien eb9162f0bb Implement the -fuse-ld= option.
This commit implements the -fuse-ld= option, so that the user
can specify -fuse-ld=bfd to use ld.bfd.

This commit re-applies r194328 with some test case changes.
It seems that r194328 was breaking macosx or mingw build
because clang can't find ld.bfd or ld.gold in the given sysroot.
We should use -B to specify the executable search path instead.

Patch originally by David Chisnall.

remove the old hacks thanks to LLVM r210144.

This brings "-arch armv7m" (etc) behaviour more in line with what's expected

same directory instead of using the default /usr/bin/ld.

Unfortunately no test because it relies on the specific place Clang is running
from.

Simon Atanasyan 60280b4e65 [Driver] Do not lose already detected set of toolchain's multilibs while
iterating over different library path suffixes and different library versions.

To find the most appropriate library for the given command line flags we
iterate over a set of disk paths. Before probe each path the already
detected set of multilibs are cleared. If the set of paths contains
existing paths which do not satisfy command line flags or do not contain
necessary libraries and object files at all we might lose found multilibs.

The patch updates variables which hold detected multilibs if we really find
a new multilib matches command line flags.

Duncan P. N. Exon Smith d971cd1b18 InstrProf: Emit runtime hook directly in IRGen
-u behaviour is apparently not portable between linkers (see cfe-commits
discussions for r204379 and r205012).  I've moved the logic to IRGen,
where it should have been in the first place.

I don't have a Linux system to test this on, so it's possible this logic
*still* doesn't pull in the instrumented profiling runtime on Linux.

I'm in the process of getting tests going on the compiler-rt side
(llvm-commits "[PATCH] InstrProf: Add initial compiler-rt test").  Once
we have tests for the full flow there, the runtime logic should get a
whole lot less brittle.

Bob Wilson 5cfc55e49f Fix an assertion failure when building for the iOS simulator. rdar://15959009
When building for i386 or x86_64 with IPHONEOS_DEPLOYMENT_TARGET set in the
environment, the toolchain correctly recognizes that the target platform is
the iOS simulator. The code in Darwin::addMinVersionArgs was not updated for
svn 197148, where isTargetIPhoneOS() was widely replaced by isTargetIOSBased().
This is kind of a strange case, though, because we probably ought to be
passing -ios_simulator_version_min to the linker, but according to the FIXME
in the code, we intentionally avoid that unless the -mios-simulator-version-min
option was used. I don't know whether it is safe to change that yet, so
for now, I am just fixing the assertion failure.

Chandler Carruth 902efc61be Teach Clang to look in its installation libdir for libraries (such as
libc++) when the installation is within the system root.

This doesn't really help cross compiles much, but we don't (currently)
have a great story around libc++, cross compiles, and who is responsible
for building and/or installing the libraries. However, it handles the
very common case of non-cross builds in a way entirely consistent with
GCC, so I'm hopeful this won't really hose anyone.

This is the second patch that I think should be backported to 3.4 to
give folks an easy to checkout and install working Clang+libc++

Tim Northover 9c7e035656 Darwin-embedded: find correct libclang_rt for embedded targets.
This refactors some of the Darwin toolchain classification to give a more solid
distinction between the three primary Darwin platforms (OS X, IOS and IOS
simulator) so that a 4th choice can be added temporarily: embedded MachO
targets.

Longer term, this support will be factored out into a separate class and no
longer classified as "darwin-eabi", but the refactoring should still be useful.

Chandler Carruth da797048d9 Teach the driver to not try to use 'lib32' multilib spellings on ARM
which doesn't use that multilib. As a consequence, fix Clang's support
for cross compiling environments that were relying on this quirk to
ensure the correct library search path ordering.

This also re-instates the new test cases from Rafael's r193528 for
cross-compiling to ARM on Ubuntu 13.10 without any of the changes to the
existing test cases (they were no longer needed).

This solution was the result of a lot of IRC debugging and trying to
understand *exactly* what quirk was being relied upon. It took some time
for me to figure out that it was the use of 'lib32' is a multilib that
was throwing a wrench in the works.

In case you are thinking that its silly to use a multilib of 'lib' at
all, entertainingly, GCC does so as well (you can see it with the
.../lib/../lib/crt1.o pattern it uses), and the 2-phase sequence of
search paths (multilib followed by non-multilib) has observable (if
dubious) consequences. =/ Yuck.

Chandler Carruth 7f8042c8f3 Find a better compromise with the default library search paths used by
Clang when linking and using a GCC installation from a GCC
cross-compiler.

This was desired already by two special case platforms (Android and
Mips), and turns out to be generally (if frustratingly) true. I've added
a substantial comment to the code clarifying the underlying assumptions
of doing actual cross compiles with Clang (or GCC for that matter!) and
help avoid further confusion here.

The end result is to realize that fully general form of PR12478 cannot
be resolved while we support existing cross-compiling GCC toolchains,
and linking with them (namely, linking against their libgcc and
libstdc++ installs). GCC installs these target libraries under
a target-specific prefix but one that may not be available within the
actual sysroot in use. When linking in this world, GCC works and Clang
should as well, but caveat emptor: DSOs from this tree must be
replicated and rpath-fixed to be found at runtime within the sysroot.

I've extended the cross compile test cases to cover these issues by
pointing them at a sysroot and actually checking the library search
paths.

Without this it is essentially impossible to understand why a particular

This also required threading a hook through the toolchain layers for
a specific toolchain implementation to print custom information under

Bill Schmidt 778d387684 [PowerPC] Support powerpc64le as a syntax-checking target.
This patch provides basic support for powerpc64le as an LLVM target.
However, use of this target will not actually generate little-endian
code.  Instead, use of the target will cause the correct little-endian
built-in defines to be generated, so that code that tests for
__LITTLE_ENDIAN__, for example, will be correctly parsed for
syntax-only testing.  Code generation will otherwise be the same as
powerpc64 (big-endian), for now.

The patch leaves open the possibility of creating a little-endian
PowerPC64 back end, but there is no immediate intent to create such a
thing.

The new test case variant ensures that correct built-in defines for
little-endian code are generated.

Chandler Carruth b427c56399 Reword and reformat some of the "Multiarch" code in the toolchain setup.
There are fundamentally two different things that were getting conflated
here.

1) A bi-arch GCC toolchain install. This is not a full blown cross
   compiler, but it supports targetting both 32-bit and 64-bit variants
   of the same architecture using multilib OS installs and runtimes.

2) A "multiarch" Debian OS/runtime layout that lays out the libraries,
   headers, etc as-if there were going to be a full blown cross compiler
   even when in reality it is just a bi-arch GCC targeting two variants.
   Also, these tend to use oddly "canonicalized" triples without the
   vendor in them unlike the typical cross compiler runtime library
   search that vanilla GCC cross compilers perform.

Now, when we mean the bi-arch nature of GCC accomplished with just
a suffix or tweak to the GCC paths, we say 'Biarch' or something
related. When we mean the Debian layout of includes and libraries, we
say multiarch or reference the multiarch triple.

In the process of reading and often renaming stuff in all these places,
also reformat with clang-format. No functionality change should be going
on here, this is just tidying up.

Chandler Carruth d6c62b66b5 Update a comment to clarify that searching the target triple bin
directory for programs used by the driver is actually the standard
behavior we want to be compatible with GCC cross compilers -- it isn't
specific to SUSE or any other distro.

Also start fleshing out testing of the different cross compilation
patterns, both with a new very bare-bones tree of cross compilers and by
extending the multilib trees. Currently, we don't correctly model doing
a cross compile using the non-triple target of a bi-arch GCC install,
but I'll add support for that (and tests) next.

ABI info and vararg support.  It also adds new tests to verify pre-defined
macros and inline asm, and updates a test for the minimum alignment change.

This version of the patch incorporates feedback from reviews by
Eric Christopher and John McCall.  Thanks to all reviewers!

Simon Atanasyan 08450bd55c Supports Sourcery CodeBench Mips toolchain directories tree.
Sourcery CodeBench and modern FSF Mips toolchains require a bit more
complicated algorithm to calculate headers, libraries and sysroot paths
than implemented by Clang driver now. The main problem is that all these
paths depend on a set of command line arguments additionally to a target
triple value. For example, let $TC is a toolchain installation directory.
If we compile big-endian 32-bit mips code, crtbegin.o is in the
$TC/lib/gcc/mips-linux-gnu/4.7.2 folder and the toolchain's linker requires
--sysroot=$TC/mips-linux-gnu/libc argument. If we compile little-endian
32-bit soft-float mips code, crtbegin.o is in the
$TC/lib/gcc/mips-linux-gnu/4.7.2/soft-float/el folder and the toolchain's
linker requires --sysroot=$TC/mips-linux-gnu/libc/soft-float/el argument.

1. Calculate MultiarchSuffix using all necessary command line options and
   use this MultiarchSuffix to detect crtbegin.o location in the
   GCCInstallationDetector::ScanLibDirForGCCTriple() routine.
2. If a user does not provide --sysroot argument to the driver explicitly,
   calculate new sysroot value based on command line options. Then use this
   calculated sysroot path:
   a. To populate a file search paths list in the Linux::Linux() constructor.
   b. To find Mips toolchain specific include headers directories
      in the Linux::AddClangSystemIncludeArgs() routine.
   c. To provide -–sysroot argument for a linker.

Note:
- The FSF's tree slightly differs (folder names) and is not supported
  yet.
- New addExternCSystemIncludeIfExits() routine is a temporary solution.
  I plan to move path existence check to the addExternCSystemInclude()
  routine by a separate commit.

Bob Wilson decc03efe8 Reapply a subset of r167567 to clean up Darwin-specific code for invoking gcc.
Unlike my previous attempt at this, this patch leaves intact the check for
whether clang can handle the input file type, and for non-Darwin toolchains it
will invoke gcc for things it cannot handle. For Darwin toolchains, the
behavior reported in pr14338 still occurs with this patch, but that is a
definite improvement from what happens currently, where it just crashes with
an assertion failure.

2012-11-23 06:14:39 +00:00
Chandler Carruth 05fb585a36 Fix the '-fuse-init-array' option to actually be an option.
Previously, this flag to CC1 was never exposed at the clang driver
layer, and if you happened to enable it (by being on Android or GCC 4.7
platform), you couldn't *disable* it, because there was no 'no' variant.
The whole thing was confusingly implemented.

Now, the target-specific flag processing gets the driver arg list, and
we use standard hasFlag with a default based on the GCC version and/or
Android platform. The user can still pass the 'no-' variant to forcibly
disable the flag, or pass the positive variant to clang itself to enable
the flag.

The test has also been substantially cleaned up and extended to cover
these use cases.

it is required to generate .init_array and .fini_array
for program targeting ARM AAPCS and AEABI.

llvm-svn: 168309
2012-11-19 11:45:31 +00:00
Chandler Carruth 76a943be7b Completely re-work how the Clang driver interprets PIC and PIE options.
There were numerous issues here that were all entangled, and so I've
tried to do a general simplification of the logic.
1) The logic was mimicing actual GCC bugs, rather than "features". These
   have been fixed in trunk GCC, and this fixes Clang as well. Notably,
   the logic was always intended to be last-match-wins like any other
   flag.
2) The logic for handling '-mdynamic-no-pic' was preposterously unclear.
   It also allowed the use of this flag on non-Darwin platforms where it
   has no actual meaning. Now this option is handled directly based on
   tests of how llvm-gcc behaves, and it is only supported on Darwin.
3) The APIs for the Driver's ToolChains had the implementation ugliness
   of dynamic-no-pic leaking through them. They also had the
   implementation details of the LLVM relocation model flag names
   leaking through.
4) The actual results of passing these flags was incorrect on Darwin in
   many cases. For example, Darwin *always* uses PIC level 2 if it uses
   in PIC level, and Darwin *always* uses PIC on 64-bit regardless of
   the flags specified, including -fPIE. Darwin never compiles in PIE
   mode, but it can *link* in PIE mode.
5) Also, PIC was not always being enabled even when PIE was. This isn't
   a supported mode at all and may have caused some fallout in builds
   with complex PIC and PIE interactions.

The result is (I hope) cleaner and clearer for readers. I've also left
comments and tests about some of the truly strage behavior that is
observed on Darwin platforms. We have no real testing of Windows
platforms and PIC, but I don't have the tools handy to figure that out.
Hopefully others can beef up our testing here.

Unfortunately, I can't test this for every platform. =/ If folks have
dependencies on these flags that aren't covered by tests, they may
break. I've audited and ensured that all the changes in behavior of the
existing tests are intentional and good. In particular I've tried to
make sure the Darwin behavior (which is more suprising than the Linux
behavior) also matches that of 'gcc' on my mac.

Chandler Carruth c0f5cd1928 Make Bitrig's clang understand -stdlib= correctly.
With this patch Bitrig can use a different c++ library without pain and
within the normal commandline parameters.

Original patch by David Hill, with lots of fixes and cleanup by me.

Rafael Espindola e8bd4e50e4 Use getArch instead of getArchName.
The darwin change should be a nop since Triple::getArchTypeForDarwinArchName
doesn't know about amd64.

If things like amd64-mingw32 are to be rejected, we should print a error
earlier on instead of silently using the wrong abi.

Remove old comment that looks out of place, this is "in clang".

Simon Atanasyan 53fefd1f6a Implement Adnroid MIPS toolchain support:
1. Add mipsel-linux-android to the list of valid MIPS target triples.
2. Add <gcc install path>/mips-r2 to the list of toolchain specific path
   prefixes if target is mipsel-linux-android.

Logan Chien c6fd820937 Rename ANDROIDEABI to Android.
Most of the code guarded with ANDROIDEABI are not
ARM-specific, and having no relation with arm-eabi.
Thus, it will be more natural to call this
environment "Android" instead of "ANDROIDEABI".

Note: We are not using ANDROID because several projects
are using "-DANDROID" as the conditional compilation
flag.

Bob Wilson 25d3bfd895 Force the OS X version to 10.6 for old-style simulator builds.
The hack of recognizing a -D__IPHONE_OS_VERSION_MIN_REQUIRED option
in place of -mios-simulator-version-min leaves the Darwin version
unspecified.  It can be set separately with -mmacosx-version-min (which
makes no sense) or inferred to match the host version (which is unpredictable
and usually wrong).  This really needs to get cleaned up, but in the
meantime, force the OS X version to 10.6 so that the behavior is sane for
the iOS simulator.  Thanks for Argyrios for the patch.

John McCall 5fb5df9c83 Restructure how the driver communicates information about the
target Objective-C runtime down to the frontend:  break this
down into a single target runtime kind and version, and compute
all the relevant information from that.  This makes it
relatively painless to add support for new runtimes to the
compiler.  Make the new -cc1 flag, -fobjc-runtime=blah-x.y.z,
available at the driver level as a better and more general
alternative to -fgnu-runtime and -fnext-runtime.  This new
concept of an Objective-C runtime also encompasses what we
were previously separating out as the "Objective-C ABI", so
fragile vs. non-fragile runtimes are now really modelled as
different kinds of runtime, paving the way for better overall
differentiation.

As a sort of special case, continue to accept the -cc1 flag
-fobjc-runtime-has-weak, as a sop to PLCompatibilityWeak.

I won't go so far as to say "no functionality change", even
ignoring the new driver flag, but subtle changes in driver
semantics are almost certainly not intended.

Rafael Espindola 66aa045fd9 Add a -fuse-init-array option to cc1 and map to the UseInitArray target
option. On the driver, check if we are using libraries from gcc 4.7 or newer
and if so pass -fuse-init-array to the frontend.
The crtbegin*.o files in gcc 4.7 no longer call the constructors listed in
.ctors, so we have to use .init_array.
