7 years ago[dsymutil] Emit real dSYM companion binaries.
Frederic Riss [Wed, 26 Aug 2015 05:10:04 +0000 (05:10 +0000)]
[dsymutil] Emit real dSYM companion binaries.

The binaries containing the linked DWARF generated by dsymutil are not
standard relocatable object files like emitted did previsously. They should be
dSYM companion files, which means they have a different file type in the
header, but also a couple other peculiarities:
 - they contain the segments and sections from the original binary in their
load commands, but not the actual contents. This means they get an address
and a size, but their offset is always 0 (but these are not virtual sections)
 - they also conatin all the defined symbols from the original binary

This makes MC a really bad fit to emit these kind of binaries. The approach
that was used in this patch is to leverage MC's section layout for the
debug sections, but to use a replacement for MachObjectWriter that lives
in MachOUtils.cpp. Some of the low-level helpers from MachObjectWriter
were reused too.

This is a follow-on from the discussion in http://reviews.llvm.org/D12154.

This change allows memset/memcpy to use SSE or AVX memory accesses for any chip that has
generally fast unaligned memory ops.

A motivating use case for this change is a clang invocation that doesn't explicitly set
the CPU, but does target a feature that we know only exists on a CPU that supports fast
unaligned memops. For example:
$ clang -O1 foo.c -mavx

Before this patch, we used different store types depending on whether the example can be
lowered as a memset or not.

However the way I tried to be backward compatible was broken: I
changed the wrapper of the TargetMachine to be a structure that
includes the DataLayout as well. However the TargetMachine is also
wrapped by the ExecutionEngine, in the more classic way. A client
using the TargetMachine wrapped by the ExecutionEngine and trying
to get the DataLayout would break.

It seems tricky to solve the problem completely in the C API
implementation. This patch tries to address this backward
compatibility in a more lighter way in the C++ API. The C API is
restored in its original state and the removed C++ API is
reintroduced, but privately. The C API is friended to the

7 years agoRequire Dominator Tree For SROA, improve compile-time
Mehdi Amini [Sun, 23 Aug 2015 22:15:49 +0000 (22:15 +0000)]
Require Dominator Tree For SROA, improve compile-time

TL-DR: SROA is followed by EarlyCSE which requires the DominatorTree.
There is no reason not to require it up-front for SROA.

Some history is necessary to understand why we ended-up here.

r123437 switched the second (Legacy)SROA in the optimizer pipeline to
use SSAUpdater in order to avoid recomputing the costly
DominanceFrontier. The purpose was to speed-up the compile-time.

Later r123609 removed the need for the DominanceFrontier in

Right after, some cleanup was made in r123724 to remove any reference
to the DominanceFrontier. SROA existed in two flavors: SROA_SSAUp and
SROA_DT (the latter replacing SROA_DF).
The second argument of `createScalarReplAggregatesPass` was renamed
from `UseDomFrontier` to `UseDomTree`.
I believe this is were a mistake was made. The pipeline was not
updated and the call site was still:
    PM->add(createScalarReplAggregatesPass(-1, false));

At that time, SROA was immediately followed in the pipeline by
EarlyCSE which required alread the DominatorTree. Not requiring
the DominatorTree in SROA didn't save anything, but unfortunately
it was lost at this point.

When the new SROA Pass was introduced in r163965, I believe the goal
was to have an exact replacement of the existing SROA, this bug
slipped through.

You can see currently:

$ echo "" | clang -x c++  -O3 -c - -mllvm -debug-pass=Structure
      FunctionPass Manager
        Dominator Tree Construction
        Early CSE

After this patch:

$ echo "" | clang -x c++  -O3 -c - -mllvm -debug-pass=Structure
      FunctionPass Manager
        Dominator Tree Construction
        Early CSE

This improves the compile time from 88s to 23s for PR17855.

And from 113s to 12s for PR16756
