[OpenMP] Encode offload target triples into comdat key for offload 
initialization code

Encoding offload target triples onto comdat group key for offload initialization
code guarantees that it will be executed once per each unique combination of
offload targets.

r371633 - [Clang][Bundler] Fix for a potential memory leak [NFC]

Log:
[Clang][Bundler] Fix for a potential memory leak [NFC]

Bundler leaks memory if it is called with -type=o but given input isn't an 
object file (though it has to have a known binary type like IR, archive, 
etc...). Memory leak is happening when binary object returned by the 
createBinary(...) call cannot be casted to an ObjectFile type. In this case 
returned BinaryOrErr object releases ownership of the binary, but no one is 
taking it (see line 626).

r374219 - [Clang][OpenMP Offload] Add new tool for wrapping offload device binaries

Log:
[Clang][OpenMP Offload] Add new tool for wrapping offload device binaries

This patch removes the remaining part of the OpenMP offload linker scripts 
which was used for inserting device binaries into the output linked binary. 
Device binaries are now inserted into the host binary with a help of the 
wrapper bit-code file which contains device binaries as data. Wrapper bit-code 
file is dynamically created by the clang driver with a help of new tool 
clang-offload-wrapper which takes device binaries as input and produces 
bit-code file with required contents. Wrapper bit-code is then compiled to an 
object and resulting object is appended to the host linking by the clang driver.

This is the second part of the patch for eliminating OpenMP linker script 
(please see https://reviews.llvm.org/D64943).

r369955 - [Clang][Bundler] Use llvm-objcopy for creating fat object files

2019-08-26 Thread Sergey Dmitriev via cfe-commits

Log:
[Clang][Bundler] Use llvm-objcopy for creating fat object files

clang-offload-bundler currently uses partial linking for creating fat object 
files, but such technique cannot be used on Windows due to the absence of 
partial linking support in the linker. This patch changes implementation to use 
llvm-objcopy for merging device and host objects instead of doing partial 
linking. This is one step forward towards enabling OpenMP offload on Windows.

[Clang][Bundler] Fix for a hang when unbundling fat binary

clang-offload-bundler tool may hang under certain conditions when it extracts a 
subset of all available device bundles from the fat binary that is handled by 
the BinaryFileHandler. This patch fixes this problem.

r370143 - [Clang][Bundler] Do not require host triple for extracting device bundles

2019-08-27 Thread Sergey Dmitriev via cfe-commits

Log:
[Clang][Bundler] Do not require host triple for extracting device bundles

Bundler currently requires host triple to be provided no matter if you are 
performing bundling or unbundling, but for unbundling operation such 
requirement is too restrictive. You may for example want to examine device part 
of the object for a particular offload target, but you have to extract host 
part as well even though you do not need it. Host triple isn't really needed 
for unbundling, so this patch removes that requirement.

[NFC]

Use a different container that preserves existing elements on modification
for storing temporary file names. Current container can make StringRefs
returned earlier invalid on reallocation.

llvm-objcopy has been changed to support adding a section and updating section 
flags
in one run (D90438), so we can now change clang-offload-bundler to run 
llvm-objcopy
tool only once when creating fat object.

[clang] c53cb2b - [Clang][Bundler] Reduce fat object size

LOG: [Clang][Bundler] Reduce fat object size

Summary:
Fat object size has significantly increased after D65819 which changed bundler 
tool to add host object as a normal bundle to the fat output which almost 
doubled its size. That patch was fixing the following issues

1. Problems associated with the partial linking - global constructors were not 
called for partially linking objects which clearly resulted in incorrect 
behavior.
2. Eliminating "junk" target object sections from the linked binary on the host 
side.

The first problem is no longer relevant because we do not use partial linking 
for creating fat objects anymore. Target objects sections are now inserted into 
the resulting fat object with a help of llvm-objcopy tool.

The second issue, "junk" sections in the linked host binary, has been fixed in 
D73408 by adding "exclude" flag to the fat object's sections which contain 
target objects. This flag tells linker to drop section from the inputs when 
linking executable or shared library, therefore these sections will not be 
propagated in the linked binary.

Since both problems have been solved, we can revert D65819 changes to reduce 
fat object size and this patch essentially is doing that.

LOG: [Clang][Driver] Disable llvm passes for the first host OpenMP offload 
compilation

Summary: With OpenMP offloading host compilation is done in two phases to 
capture host IR that is passed to all device compilations as input. But it 
turns out that we currently run entire LLVM optimization pipeline on host IR on 
both compilations which may have unpredictable effects on the resulting code. 
This patch fixes this problem by disabling LLVM passes on the first 
compilation, so the host IR that is passed to device compilations will be 
captured right after front end.
