Argyrios Kyrtzidis Don't map a file:line:col triplet that is inside the preamble range to
a "loaded" location of the precompiled preamble.

Instead, handle specially locations of preprocessed entities:
-When looking up for preprocessed entities, map main file locations inside the
 preamble range to a preamble loaded location.
-When getting the source range of a preprocessing cursor, map preamble loaded
 locations back to main file locations.

Fixes rdar://10175093 & http://llvm.org/PR10999

Argyrios Kyrtzidis Remove SourceManager::getLocation().
It's not descriptive enough and it's just a call of translateFileLineCol()
followed by a call to getMacroArgExpandedLocation(), which is better to be
called explicitly since it has a certain cost and is not always required.

Argyrios Kyrtzidis Associate the macro arguments location map with a FileID instead
of a ContentCache, since multiple FileIDs can have the same ContentCache
but the expanded macro arguments locations will be different.

Chandler Carruth Add a test for the display of diagnostic options and categories. This
would have caught a bug I introduced during refactoring. Silly me
thinking this was all well tested already...

If any of this is already covered by other tests, let me know. I looked
around and didn't see any.

Chandler Carruth Extract the actual printing of the message string into a helper
function. Doing this conveniently requires moving the word wrapping to
use a StringRef which seems generally an improvement. There is a lot
that could be simplified in the word wrapping by using StringRef that
I haven't looked at yet...

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140524 91177308-0d34-0410-b5e6-96231b3b80d8

Chandler Carruth Switch the emission of diagnostics without a source location to
a dedicated path. The logic for such diagnostics is much simpler than
for others.

This begins to make an important separation in this routine. We expect
most (and most interesting) textual diagnostics to be made in the
presence of at least *some* source locations and a source manager.
However the DiagnosticConsumer must be prepared to diagnose errors even
when the source manager doesn't (yet) exist or when there is no location
information at all. In order to sink more and more logic into the
TextDiagnostic class while minimizing its complexity, my plan is to
force the DiagnosticConsumer to special case diagnosing any locationless
messages and then hand the rest to the TextDiagnostic class. I'd
appreciate any comments on this design. It requires a bit of code
duplication in order to keep interfaces simple. Alternatively, if we
really need TextDiagnostic to be capable of handling diagnostics even in
the absence of a viable SourceManager, then this split isn't necessary.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140525 91177308-0d34-0410-b5e6-96231b3b80d8
0ef8988
Chandler Carruth Hoist and beef up the asserts about the level of infrastructure expected
when working with a diagnostic attached to a source location. Also
comment more thoroughly why its important to handle non-location
diagnostic messages separately.

Finally, hoist the creation of the TextDiagnostic object up to the
beginning of the location-based diagnostics. This paves the way for
sinking more and more of the logic into this class. When everything
below this constructor is sunk into the TextDiagnostic class it should
be sufficiently "feature complete" to accomplish my two goals:
1) Have the printing of a macro expansion note use the exact same code
   as any other note.
2) Be able to implement clang_formatDiagnostic in terms of this class.

Chandler Carruth Add back support for a manually formatted section of the diagnostic
message. Specifically, we now only line-wrap the first line of te
diagnostic message and assume the remainder is manually formatted. While
adding it back, simplify the logic for doing this.

Finally, add a test that ensures we actually preserve this feature. =D
*Now* its not dead code. Thanks to Doug for the test case.

Chandler Carruth Begin fixing Clang's predefined macros for various architectures. This
is *very* much a WIP that I'll be refining over the next several
commits, but I need to get this checkpoint in place for sanity.

This also adds a much more comprehensive test for architecture macros,
which is roughly generated by inspecting the behavior of a trunk build
of GCC. It still requires some massaging, but eventually I'll even check
in the script that generates these so that others can use it to append
more tests for more architectures, etc.

Next up is a bunch of simplification of the Targets.cpp code, followed
by a lot more test cases once we can reject invalid architectures.

Chandler Carruth Clean up a bit of the uses of CPU in the TargetInfo classes. This makes
it an error if a CPU is provided for a target that doesn't implement
logic handling CPU settings, to match the ABI settings. It also removes
the CPU parameter from the getDefaultFeatures method. This parameter was
always filled in with the same value as setCPU was called with, and at
this point every single target implementation that referenced the CPU
within this function has needed to store the CPU via setCPU anyways in
order to implement other interface points.

Chandler Carruth Introduce an enumeration for the x86 CPUs recognized by Clang. I've

wrong, please chime in.

Chandler Carruth Switch the X86TargetInfo object from a string representation of the
selected CPU model to the enumeration. This parses the string
representation once using a StringSwitch on SetCPU. It returns an error
for strings which are not recognized (yay!). Finally it replaces
ridiculous if-chains with switches that cover all enumerators.

The last change required adding several missing entries to the features
function. These were obvious on inspection. Yay for a pattern that gives
warnings when we miss one.

No new test cases yet, as I want to get the 64-bit errors working first.
I'll then start fleshing out the testing more. Currently I'm primarily
testing on Linux, but I'm hoping check whether there are interesting
differences on darwin before long...

where the same diagnostic consumer sees diagnostics for multiple

CFTypeRef (aka const void*), but this is clearly a good
foundation for improving toolage in this area.

Chandler Carruth Revert r140604: "Let -B work for ld paths on Linux."
This patch may do what it describes, it may not. It's hard to tell as
its completely unclear what this is supposed to do. There are also no
test cases. More importantly, this seems to have broken lots of linker
invocations on multilib Linux systems.

The manual pages for 'ld' on Linux mention translating a '=' at the
beginning of the path into a *configure time* sysroot prefix (this is,
I believe, distinct from the --sysroot flag which 'ld' also can
support). I tested this with a normal binutils 'ld', a binutils 'ld'
with the sysroot flag enabled, and gold with the sysroot flag enabled,
and all of them try to open the path '=/lib/../lib32', No translation
occurs.

I think at the very least inserting an '=' needs to be conditioned on
some indication that it is supported and desired. I'm also curious to
see what toolchain and whan environment cause it to actually make
a difference.

I'm going to add a test case for basic sanity of Linux 'ld' invocations
from Clang in a follow-up commit that would have caught this.

part on patches by Peter Collingbourne.

We diverge from the C++11 standard in a few areas, mostly related to checking
constexpr function declarations, and not just definitions. See WG21 paper
N3308=11-0078 for details.

Function invocation substitution is not available in this patch; constexpr
functions cannot yet be used from within constant expressions.

rjmccall Make -fobjc-nonfragile-abi the -cc1 default, since it's the
increasingly prevailing case to the point that new features
like ARC don't even support the fragile ABI anymore.

This required a little bit of reshuffling with exceptions
because a check was assuming that ObjCNonFragileABI was
only being set in ObjC mode, and that's actually a bit
obnoxious to do.

Most, though, it involved a perl script to translate a ton
of test cases.

Mostly no functionality change for driver users, although
there are corner cases with disabling language-specific
exceptions that we should handle more correctly now.

Chandler Carruth Rework the selection of builtin library search paths on Linux to
precisely match the pattern and logic used by the GCC driver on Linux as
of a recent SVN checkout.

This happens to follow a *much* more principled approach. There is
a strict hierarchy of paths examined, first with multilib-suffixing,
second without such suffixing. Any and all of these directories which
exist will be added to the library search path when using GCC.

There were many places where Clang followed different paths, omitted
critical entries, and worst of all (in terms of challenges to debugging)
got the entries in a subtly wrong order.

If this breaks Clang on a distro you use, please let me know, and I'll
work with you to figure out what is needed to work on that distro. I've
checked the behavior of the latest release of Ubuntu, OpenSUSE, Fedora,
and Gentoo. I'll be testing it on those as well as Debian stable and
unstable and ArchLinux. I may even dig out a Slackware install.

No real regression tests yet, those will follow once I add enough
support for sysroot to simulate various distro layouts in the testsuite.

Chandler Carruth Add initial support for applying the sysroot to library search paths.
This is still very much a WIP, but sysroot was completely broken before
this so we are moving closer to correctness.

The crux of this is that 'ld' (on Linux, the only place I'm touching
here) doesn't apply the sysroot to any flags given to it. Instead, the
driver must translate all the paths it adds to the link step with the
system root. This is easily observed by building a GCC that supports
sysroot, and checking its driver output.

This patch just fixes the non-multilib library search paths. We should
also use this in many other places, but first things first.

This also allows us to make the Linux 'ld' test independent of the host
system. This in turn will allow me to check in test tree configurations
based on various different distro's configuration. Again, WIP.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140990 91177308-0d34-0410-b5e6-96231b3b80d8

Chandler Carruth Teach the logic for locating an installed GCC about the system root.
This requires fixing a latent bug -- if we used the default host triple
instead of an autodetected triple to locate GCC's installation, we
didn't go back and fix the GCC triple. Correct that with a pile of
hacks. This entire routine needs a major refactoring which I'm saving
for a subsequent commit. Essentially, the detection of the GCC triple
should be hoisted into the same routine as we locate the GCC
installation: the first is intrinsically tied to the latter. Then the
routine will just return the triple and base directory.

Also start to bring the rest of the library search path logic under
test, including locating crtbegin.o. Still need to test the multilib and
other behaviors, but there are also bugs in the way of that.

621e6a6
Chandler Carruth Relax an assertion here a bit. This doesn't really matter, as we won't
include *any* path on crtbegin.o unless we actually find such a file via
one of the search paths. We still strictly check the search paths right
after this, so we'll catch any issues there.

The reason for this is that the driver does some normalization of the
path on the actual object file, and this changes the textual format of

Chandler Carruth Enable generic multilib support on 32bit hosts. Previously this was only
enabled for debian hosts, which is quite odd. I think all restriction on
when Clang attempts to use a multilib installation should go away. Clang
is fundamentally a cross compiler. It behaves more like GCC when built
as a cross compiler, and so it should just use multilib installs when
they are present on the system. However, there is a very specific
exemption for Exherbo, which I can't test on, so I'm leaving that in
place.

With this, check in a generic test tree for multilib on a 32-bit host.
This stubs out many directories that most distributions don't use but
that uptsream GCC supports. This is intended to be an agnostic test that
the driver behaves properly compared with the GCC driver it aims for
compatibility with.

Also, fix a bug in the driver that this testing exposed (see!) where it
was incorrectly testing the target architecture rather than the host
architecture.

If anyone is having trouble with the tree-structure stubs I'm creating
to test this, let me know and I can revisit the design. I chose this
over (for example) a tar-ball in order to make tests run faster at the
small, hopefully amortized VCS cost.

Chandler Carruth Test a multilib setup on a 64-bit host. This is the far more common
configuration, although the test still stubs out more directories than
are necessary or common in order to exercise all of the lookup paths
observed with upstream GCC.

This finishes testing the distribution-independent and
GCC-installation-independent parts of the library path search logic.
More testing is still needed for the triple detection, GCC-installation
detection, and handling distributions with unusual configurations.

is designed to allow the detection to record more rich information about
the installation than just a single path.

Mostly, the functionality remains the same. This is primarily
a factoring change. However, the new factoring immediately fixes one
issue where on ubuntu we didn't walk up enough layers to reach the
parent lib path. I'll have a test tree for that once I finish making the
Ubuntu tree work reasonably.

Chandler Carruth Factor the data apart from the logic of locating various GCC
installations. This first selects a set of prefixes and a set of
compatible triples for the current architecture. Once selected, we drive
the search with a single piece of code.

This code isn't particularly efficient as it stands, but its only
executed once. I'm hoping as I clean up the users of this information,
it will also slowly become both cleaner and more efficient.

This also changes the behavior slightly. Previously, we had an ad-hoc
list of prefixes and triples, and we only looked for some triples
beneath specific prefixes and vice versa. This has led to lots of
one-off patches to support triple X, or support lib dir Y. Even without
going to a fully universal driver, we can do better here. This patch
makes us always look first in either 'lib32' or 'lib64' on 32- or 64-bit
hosts (resp.). However, we *always* look in 'lib'.

Currently I have one lingering problem with this strategy. We might find
a newer or better GCC version under a different (but equally compatible)
triple. Fundamentally, this loop needs to be fused with the one below.
That's my next patch.

Chandler Carruth Fuse the two halves of the GCC installation detection. This is
significantly cleaner (IMO) and more principled. We now walk down each
layer of the directory hierarchy searching for the GCC install. This
change does in fact introduce a significant behavior change in theory,
although in practice I don't know of any distro that will be impacted by
it negatively, and Debian may (untested) get slightly better through it.

Specifically, the logic now looks exhaustively for patterns such as:

  /usr/lib/<triple>/gcc/<triple>

Previously, this would only be selected if there was *also*
a '/usr/lib/gcc/<triple>' directory, or if '<triple>' were the excat
DefaultHostTriple in the driver.

There is a 4-deep nested loop here, but it doesn't do terribly many
filesystem operations, as we skip at each layer of that layer's
directory doesn't exist.

There remains a significant FIXME in this logic: it would be much better
to first build up a set of candidate components for each of the four
layers with a bottom-up pruning such as this, but then select the final
installation using a top-down algorithm in order to find the newest GCC
installation available, regardless of which particular path leads to it.

Chandler Carruth Invert the loop for detecting installed GCC trees. This make the loop
find the newest GCC available, among other goodness. It makes the entire
system much less prone to error from prefixes and/or system roots
pruning early the set of triples and GCC versions available.

Also, improve some comments and simplify the forms of some of the loops.

This causes the driver to stat directories more often than is strictly
necessary, but the alternatives which I looked at that still
accomplished this goal needed quite a bit more code and were likely not
much faster.

Test cases for this, now that our behavior here is significantly more
principled and predictable, should come tomorrow as I walk back through
VMs looking for edge cases that are missed after this.

Planning to implement that next as the current approcah while thorough

Chandler Carruth Rework the search for a GCC installation still further. This combines
two fundamental changes, as they ended up being interrelated.

The first is to walk from the root down through the filesystem so that
we prune subtrees which do not exist early. This greatly reduces the
filesystem traffic of this routine. We store the "best" GCC version we
encounter, and look at all of the GCC installations available.

Also, we look through GCC versions by scanning the directory rather than
using a hard-coded list of versions. This has several benefits. It makes
it much more efficient to locate a GCC installation even in the presence
of a large number of different options by simply reading the directory
once. It also future-proofs us as new GCC versions are released and
installed. We no longer have a hard coded list of version numbers, and
won't need to manually updated it. We can still filter out known-bad
versions as needed. Currently I've left in filtering for all GCC
installations prior to 4.1.1, as that was the first one supported
previously.

6d9694c
Chandler Carruth Now that multiple prefixes are much cheaper to search for GCC
installations, support them when installed directly under the system
root ('/lib/gcc/...' essentially).

With this, Clang can correctly detect and use a cross-compiling GCC
installation within a system root and use it.

Again, test cases will be coming in later commits, as I'm going to write
a few test cases that exercise nearly all of this logic.

Chandler Carruth Implement the feature I was originally driving toward when I started
this saga. Teach the driver to detect a GCC installed along side Clang
using the existing InstalledDir support in the Clang driver. This makes
a lot of Clang's behavior more automatic when it is installed along side
GCC.

Also include the first test cases (more to come, honest) which test both
the install directory behavior, and the version sorting behavior to show
that we're actually searching for the best candidate GCC installation
now.
