Necessary to give disassembler users (like darwin's otool) a possibility to
dlopen libLTO and still initialize the required LLVM bits. This used to go
through libMCDisassembler but that's a gross layering violation, the MC layer
can't pull in functions from the targets. Adding a function to libLTO is a bit
of a hack but not worse than exposing other disassembler bits from libLTO.

Fixes PR14362.

The implementations already diverged a bit, merge them back together.

The last remaining bit is "bcl 20, 31, AnonSymbol", which I couldn't find the
instruction definition for. Only whitespace changes in assembly output.

No functionality change.

[asan/tsan] get rid of kPageSize completely in favor of GetPageSizeCached(). This makes the code friendly to more platforms

llvm-svn: 168537

We now store the Register and Offset directly. MachineLocation is gone (from
this file)!

This untangles the switch cases of the old Move and RelMove opcodes a bit
and makes it clear how to add new instructions.

Give MCCFIInstruction a single, private constructor and add helper static
methods that create each type of cfi instruction. This is is preparation
for changing its representation. The representation with a pair
MachineLocations older than MC and has been abused quiet a bit to support
more cfi instructions.

It can delete the block, and the loop continues on free'd memory.
No change in output. Found by valgrind.

- Handle EINVAL return code from ptrace(GETSIGINFO, ...): not an error, but 'group-stop' state on Linux
- propagate SIGSTOP to inferior in above case
- this commit resolves the failure in expression_command/timeout testcase

Thanks to Sean Callanan & Matt Kopec for helping debug this problem

it will expand any .cfi_* directives in the input assembly.

Unfortunately this cannot replace elf-dump in tests as the asm streamer
cannot relax the line advance opcodes.

[asan] get rid of some of the uses of kPageSize. The intent is to get rid of it completely to support platforms with multiple possible page sizes.

Decl::isUsed checks the attribute. If the function had a body just the check

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.
