Kostya Serebryany ec34665de9 [asan] disable asan-detect-invalid-pointer-pair (was enabled by mistake)
llvm-svn: 202390
2014-02-27 12:56:20 +00:00
Kostya Serebryany 796f6557bf [asan] *experimental* implementation of invalid-pointer-pair detector (finds when two unrelated pointers are compared or subtracted). This implementation has both false positives and false negatives and is not tuned for performance. A bug report for a proper implementation will follow.

Chandler Carruth 55cc48f403 [docs] Actually spell out the new version requirements for the host C++
toolchain of LLVM. These are already being enforced by the build system
and have been discussed quite a few times on the lists, but
documentation is important. =]

Also, garbage collect the majority of the information about broken host
GCC toolchains. These aren't really relevant any more as they're all
older than the minimum requirement. I've left a few notes about
compilers one step older than the current requirement as these compilers
are at least conceivable to use, and it's better to preserve this kind
of hard-won institutional knowledge.

The next step will be some specific docs on how to set up a sufficiently
modern host toolchain if your system doesn't come with one. But that'll
be tomorrow. =]

Chandler Carruth 8356ce4121 [docs] Clean up some of the required software to not mention irrelevant
bits of software and to use a modern GCC version.

The Subversion bit was weird anyways -- it has nothing to do with
compiling LLVM. Also, there are many other ways to get at the trunk
source (git, git-svn, etc).

The TeXinfo thing... I have no idea about. But you can get a working
LLVM w/o it pretty easily. If man pages or something are missing, that
hardly seems like a problem. If folks really want this back, let me
know, but it seems mostly like a distraction.

I'd still like to separate this into:
- Required software to compile.
- Optional software to compile.
- Required software for certain *contributor* activities (like
  regenerating configure scripts).

Also we need to mention that there are multiple options for build
systems, and the differences.

Also we should mention Windows.

Also probably other stuff I'm forgetting.

I'm wondering if this whole thing needs to be shot in the head and we
should just start a new, simpler getting started that doesn't have so
many years of accumulated stuff that is no longer relevant.

Chandler Carruth 41e1b91750 [docs] Delete tons of bad information in the requirements section of the
getting started guide.

Some highlights:
- I heard there was this Clang compiler that you could use for your
  host compiler. Not sure though.
- We no longer have a GCC frontend with weird build restrictions.
- Windows is doing a bit better than partially supported.
- We nuked everything to do with itanium.
- SPUs? Really?
- Xcode 2.5 and gcc 4.0.1 are really not a concern -- they don't work.
- OMG, we actually tried building LLVM on Alpha? Really?
- PowerPC works pretty well these days.

There is still a lot of stuff here I'm pretty dubious about, but I nuked
most of what was actively misleading, out of date, or patently wrong.
Some of it (mingw stuff especially) isn't really lacking, its just that
the comments here were actively wrong. Hopefully folks that know those
platforms can add back correct / modern information.

Daniel Sanders 9f088ba322 Stop test/CodeGen/X86/v4i32load-crash.ll targeting non-X86-64 targets.
Summary:
Fixes an issue where a test attempts to use -mcpu=x86-64 on non-X86-64 targets.
This triggers an assertion in the MIPS backend since it doesn't know what ABI to
use by default for unrecognized processors.

Alexey Samsonov 8a25994c25 [CMake] Teach build system to build/test compiler-rt with a just-built Clang
With this change, one may set LLVM_BUILD_EXTERNAL_COMPILER_RT option
to build compiler-rt libraries with just-built Clang.

  make compiler-rt
in the build tree will build all compiler-rt libraries with just-built Clang
and copy them to the proper location in the Clang resource directory.

  make check-compiler-rt
will run the compiler-rt test suite using just-built Clang and runtime
libraries.

The goal is to make LLVM_BUILD_EXTERNAL_COMPILER_RT the default, so that
we can always build compiler-rt libraries with Clang, not the host compiler,
and for all the platforms Clang can target.

Evgeniy Stepanov 322e89c4e2 [asan] Install asan_device_setup to bin/ when targetting Android.
asan_device_setup is a utility that prepares a device to run code built with
ASan. Essentially, it installs ASan runtime library into the system. For this
reason, it has to be at a predictable relative path from the runtime library
itself. We also plan to distribute this utility, packaged with runtime library
and maybe llvm-symbolizer, to the users.

Argyrios Kyrtzidis 1b7ed91e44 [ASTUnit] Fix use-after-free bug in ASTUnit::getMainBufferWithPrecompiledPreamble().
With r197755 we started reading the contents of buffer file entries, but the
buffers may point to ASTReader blobs that have been disposed.

Fix this by having the CompilerInstance object keep a reference to the ASTReader
as well as having the ASTContext keep reference to the ExternalASTSource.

This was very difficult to construct a test case for.

Eric Christopher 740a833a3b If we're only emitting line tables for a particular CU then don't add
any ranges to the list of ranges for the CU as we don't want to emit
them anyway. This ensures that we will still emit ranges if we have
a compile unit compiled with only line tables and one compiled with
full debug info requested (we'll emit for the one with full debug info).

Update testcase metadata accordingly to continue emitting ranges.
