review of the previous patch that introduced this week.

llvm-svn: 201723

In the Microsoft ABI, the vftable is laid out as if all methods in every
overload set were declared in reverse order of declaration at the point
of declaration of the first overload in the set.

Previously we only considered virtual methods in an overload set, but
MSVC includes non-virtual methods for ordering purposes.

Fixes PR18902.

Clang itself only emits CodeView line tables, so it seems more
consistent to ask cl.exe for the same format.

llvm-svn: 201718

Implement LWG Issues #2329 and #2332 - disallow iterators into temporary regexes and regexes into temporary strings

Added a documentation category for statement attributes so that things like clang::fallthrough can be documented.

Some of these headings had the incorrect number of "underlines" and so would get warnings when generating the content from Sphinx. No functional changes intended.

TargetLoweringBase is implemented in CodeGen, so before this patch we had
a dependency fom Target to CodeGen. This would show up as a link failure of
llvm-stress when building with -DBUILD_SHARED_LIBS=ON.

This fixes pr18900.

llvm-svn: 201711

This should clean up the new test failures caused by r201614

And add a decorator for llvm.org/pr18200

Patch by John Wolfe.

llvm-svn: 201708

Implement x86_64 debug register read/write in support of hardware
watchpoints. Hoist LinuxThread::TraceNotify code back into
POSIXThread::TraceNotify()

Patch by John Wolfe.

We still need to rework this later to avoid the #ifdef FreeBSD.

llvm-svn: 201704

Implement LWG Issue: 2280. begin/end for arrays should be constexpr and noexcept, plus a drive-by fix for cbegin/cend suggested by Peter Sommerlad.

llvm-svn: 201703

IdenticalExprChecker now warns if any expressions in a logical or bitwise
chain (&&, ||, &, |, or ^) are the same. Unlike the previous patch, this
actually checks all subexpressions against each other (an O(N^2) operation,
but N is likely to be small).

Patch by Daniel Fahlgren!

llvm-svn: 201702

This extends the checks for identical expressions to handle identical
statements, and compares the consequent and alternative ("then" and "else")
branches of an if-statement to see if they are identical, treating a single
statement surrounded by braces as equivalent to one without braces.

This does /not/ check subsequent branches in an if/else chain, let alone
branches that are not consecutive. This may improve in a future patch, but
it would certainly take more work.

llvm-svn: 201701

r201608 made llvm corretly handle private globals with MachO. r201622 fixed
a bug in it and r201624 and r201625 were changes for using private linkage,
assuming that llvm would do the right thing.

They all got reverted because r201608 introduced a crash in LTO. This patch
includes a fix for that. The issue was that TargetLoweringObjectFile now has
to be initialized before we can mangle names of private globals. This is
trivially true during the normal codegen pipeline (the asm printer does it),
but LTO has to do it manually.

llvm-svn: 201700

The same code (~20 lines) for initializing a TargetOptions object from CodeGen
cmdline flags is duplicated 4 times in 4 different tools. This patch moves it
into a utility function.

Since the CodeGen/CommandFlags.h file defines cl::opt flags in a header, it's
a bit of a touchy situation because we should only link them into tools. So this
patch puts the init function in the header.

This is consistent with the way CodeGen acheives this. However, CodeGen
always selects mips32 (even when the architecture is mips64).

Thanks to Konrad Kleine for reporting the inconsistency!

llvm-svn: 201693

llvm-svn: 201692

Use camel-case names, remove some dead code, and fix a copy-and-pasted test.

llvm-svn: 201691

llvm-svn: 201690

No functional change.

llvm-svn: 201689

Since r201608 got reverted, it is not safe to use private linkage in these cases
until it is committed back.
