Aaron Ballman 74eeeae3d3 Laying the basic groundwork for table generating the diagnostics for attribute subjects. This makes some modifications to the way subjects are listed in Attr.td, and updates the attr emitter to handle the new constructs.
I have disabled some attribute subject lines on purpose in Attr.td;
this part is a WIP with the goal being to restore those subjects
incrementally. By commenting them out, it leaves the original behavior
the same as before for those attributes and so those are not
functionality changes.

Alexey Samsonov 1c256cbcc4 [Sanitizer] Add rudimentary support for using libbacktrace in symbolizer.
More steps are needed to actually make it usable:
* sanitizer runtimes should be compiled with -DSANITIZER_LIBBACKTRACE.
* libbacktrace headers should be installed.
* user has to manually link in libbacktrace.a into the executable.

We can easily solve the first two problems in the build system, but
detecting/linking libbacktrace to all the tests we have and end-user programs
is more challenging (and will unlikely work w/o Driver support).

Based on the patch by Jakub Jelinek!

Peter Zotov 40a5d378f6 [OCaml] Embed rpath into stub libraries and native executables
This commit embeds a set of linker flags with hardcoded paths to
the LLVM shared library on --enable-shared builds into .cmxa files
and stub dynamic libraries. This solution closely follows existing
rules for rpath in the LLVM tools, which had to be modified because
of differences in toolchain.

Without this patch, OCaml tests as well as opam bindings broke,
as neither of those updates LD_LIBRARY_PATH to include
the $prefix/lib directory.

David Majnemer 192d1798b2 Sema: Instantiate local class and their members appropriately
We would fail to instantiate them when the surrounding function was
instantiated. Instantiate the class and add it's members to the list of
pending instantiations, they should be resolved when we are finished
with the function's body.

This fixes PR9685.

Rafael Espindola 09cf06c75e Cleanup and test X86AsmPrinter::printPCRelImm.
It is only used for asm printing.

On X86 we put basic block addresses on register before passing them to inline
asm, so the MO_MachineBasicBlock case was dead.

MO_ExternalSymbol was dead since any symbol being passed to inline asm
is represented as MO_GlobalAddress.

The MO_GlobalAddress and MO_Register cases were not tested.

Rafael Espindola 2d30ae2be9 Use simple section names for COMDAT sections on COFF.
With this patch we use simple names for COMDAT sections (like .text or .bss).
This matches the MSVC behavior.

When merging it is the COMDAT symbol that is used to decide if two sections
should be merged, so there is no point in building a fancy name.

This survived a bootstrap on mingw32.

Rui Ueyama 3e873b0578 [PECOFF] Add a generic section writer.
Instead of having multiple SectionChunks for each section (.text, .data,
.rdata and .bss), we could have one chunk writer that can emit any sections.
This patch does that -- removing all section-sepcific chunk writers and
replace them with one "generic" writer.

This change should simplify the code because it eliminates similar-but-
slightly-different classes.

It also fixes an issue in the previous design. Before this patch, we could
emit only limited set of sections (i.e. .text, .data, .rdata and .bss). With
this patch, we can emit any sections.

Arnold Schwaighofer a2c8e008d2 LoopVectorizer: Truncate i64 trip counts of i32 phis if necessary
In signed arithmetic we could end up with an i64 trip count for an i32 phi.
Because it is signed arithmetic we know that this is only defined if the i32
does not wrap. It is therefore safe to truncate the i64 trip count to a i32
value.

Fixes PR18049.
