The concept of such a software distribution is not tied to the Linux kernel;
for example Debian GNU/Linux, Debian GNU/Hurd, and Debian GNU/kFreeBSD all
share the same source packages and generally the same user-space configuration.

Each toolchain has a set of tools, but they are all of known types. It can
have a linker, an assembler, a "clang" (compile, analyze, ...) a non-clang
compiler, etc.
Instead of keeping a map, just have member variable for each type of tool.

The general pattern now is that Foobar::constructTool only creates tools
defined in the tools::foobar namespace and then delegates to the parent.
The remaining duplicated code is now in the tools themselves.

In cooperation with the LLVM patch, this should implement all scalar front-end
parts of the C and C++ ABIs for AArch64.
This patch excludes the NEON support also reviewed due to an outbreak of
batshit insanity in our legal department. That will be committed soon bringing
the changes to precisely what has been approved.
Further reviews would be gratefully received.

This patch changes the behavior of the -fsanitize=address flag, making it use the dynamic runtime library (libclang_rt.asan_osx_dynamic.dylib) instead of the static one. It also drops the CoreFoundation dependency, since the dynamic runtime doesn't need it.

to read and tell that it is a SWO -- we now descend through the

Also comment it a bit better and make it a total ordering by sorting on
the text of the suffix if necessary.
None of this should really be a visible change.

Shuffling order causes the wrong one to win.
CMake didn't exhibit this problem because Clang's has *no* guards.
I'll fix this properly tomorrow when Eric and I can check both build
systems and get them to DTRT, but for now unbreak some bots by hoisting
this header.

uncovered.
This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.
I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.

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.
llvm-svn: 168505
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.
llvm-svn: 168473
The dynamic linker of Android does not support .ctors/.dtors.
We should emit .init_array and .fini_array regardless the
gcc version.
NOTE: This patch does not affect the ARM backend, because
it is required to generate .init_array and .fini_array
for program targeting ARM AAPCS and AEABI.
llvm-svn: 168309
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.

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".

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.

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.

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.

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.
