llvm-svn: 184109

This reverts commit r184100.

It was faling on some bots:
http://bb.pgr.jp/builders/cmake-clang-i686-mingw32/builds/1973/steps/test_clang/logs/Clang%20%3A%3A%20SemaCXX__cxx1y-contextual-conversion-tweaks.cpp

The main advantages here are way better heuristics, taking into account not
just loop depth but also __builtin_expect and other static heuristics and will
eventually learn how to use profile info. Most of the work in this patch is
pushing the MachineBlockFrequencyInfo analysis into the right places.

This is good for a 5% speedup on zlib's deflate (x86_64), there were some very
unfortunate spilling decisions in its hottest loop in longest_match(). Other
benchmarks I tried were mostly neutral.

This changes register allocation in subtle ways, update the tests for it.
2012-02-20-MachineCPBug.ll was deleted as it's very fragile and the instruction
it looked for was gone already (but the FileCheck pattern picked up unrelated
stuff).

vectorizing loops with memory accesses to non-zero address spaces. It
simply dropped the AS info. Fixes PR16306.

This is the first patch toward full DLL support. With this patch, lld can
read .lib file for a DLL.

To better support per-translation unit replacements, any real work is being
moved out of ActionFactory and into Transform. In this revision, that means
file override application.

For simplification, Transform no longer inherits from SourceFileCallbacks.
TransformTest required updating as a result.

triggers an error on MS targets where __SIZE_TYPE__ expands to 'long long'.

This patch also adds a simpler version of sys::fs::remove and a tool_output_file
constructor for when we already have an open file.

Make use of getTypeSizeInChars to detect structs/unions of zero size. It allows
more accurate detection of types of zero size. It however has a side effect -
sequence of used types may change, that is why the test 'override-layout' was
modified.

llvm-ar is the only tool that needs to write archive files. Every other tool
should be able to use the lib/Object interface.

This adds a bunch of llvm::opt name specifiers to all the uses of types
from that namespace.

Fix a problem in ExpressionParser leading to trailing comments affecting indentation of an expression after a line break.

Summary:
E.g. the second line in 

return aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa +
           b; //

is indented 4 characters more than in

return aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa +
       b;

WhitespaceManager::replaceWhitespaceInToken.For correct alignment of new
segments of line comments in order to align them correctly. Don't set
BreakBeforeParameter in breakProtrudingToken for line comments, as it introduces
a break after the _next_ parameter. Added tests for related functions.

The untemplated implementation of getParents() doesn't need to be in a
header file.

RecursiveASTVisitor.h is full of repeated macro expansion.  Moving this
include to ASTContext.cpp speeds up compilation of
LambdaMangleContext.cpp, a small C++ file with few includes, from 3.7s
to 2.8s for me locally.  I haven't measured a full build, but it can't
hurt.

I had to fix a few static analyzer files that were depending on
transitive includes of C++ AST headers.

This broke for example the 'not' utility, if a directory called
'FileCheck' is executable and in the path before the actual 'FileCheck'.

This patch steals the implementation of the "old" PathV1 canExecute
implementation:
- checks for R_OK (file readable): this is necessary for executing
  scripts; we should not regress here unless we have good reasons
- checks for S_ISREG; if we want to get rid of this, we'd need to
  change all callers who already made the assumption when depending
  on Path V1.

llvm-objdump should provide some way of printing out the addends present in the
.rela sections for debugging purposes if nothing else.

llvm-svn: 184072

This change adds functionality to add more sections like .gcc_except_table,
.data.rel.local, .data.rel.ro into the default section map, so that they are
all merged into appropriate output sections.

This also makes c++ static binaries comparable to what you get with the default
linker.

Adds a test for testing the functionality.
