Jonas Devlieghere [Thu, 9 Mar 2023 02:28:50 +0000 (18:28 -0800)]
[lldb] Introduce new SymbolFileJSON and ObjectFileJSON

Introduce a new object and symbol file format with the goal of mapping
addresses to symbol names. I'd like to think of is as an extremely
simple textual symtab. The file format consists of a triple, a UUID and
a list of symbols. JSON is used for the encoding, but that's mostly an
implementation detail. The goal of the format was to be simple and human
readable.

The new file format is motivated by two use cases:

 - Stripped binaries: when a binary is stripped, you lose the ability to
   do thing like setting symbolic breakpoints. You can keep the
   unstripped binary around, but if all you need is the stripped
   symbols then that's a lot of overhead. Instead, we could save the
   stripped symbols to a file and load them in the debugger when
   needed. I want to extend llvm-strip to have a mode where it emits
   this new file format.

 - Interactive crashlogs: with interactive crashlogs, if we don't have
   the binary or the dSYM for a particular module, we currently show an
   unnamed symbol for those frames. This is a regression compared to the
   textual format, that has these frames pre-symbolicated. Given that
   this information is available in the JSON crashlog, we need a way to
   tell LLDB about it. With the new symbol file format, we can easily
   synthesize a symbol file for each of those modules and load them to
   symbolicate those frames.

Here's an example of the file format:

 {
     "triple": "arm64-apple-macosx13.0.0",
     "uuid": "36D0CCE7-8ED2-3CA3-96B0-48C1764DA908",
     "symbols": [
         {
             "name": "main",
             "type": "code",
             "size": 32,
             "address": 4294983568
         },
         {
             "name": "foo",
             "type": "code",
             "size": 8,
             "address": 4294983560

[flang] Fix linker test on Windows.

The linker-flags.f90 test checks for the linker command line. The `-target` indicates cross-compiling, the toolchain executables themselves are still running on the native platform. If it is Windows, the driver will try to fully resolve the path to `ld` which may include an `.exe` suffix.

This MR follows a similar approach to https://reviews.llvm.org/D112928.

This patch adds support to convert conv_2D operation with either unit height or unit width to conv_1D operation.

This is useful when 2D convolution is tiled to have a single dimension for either height or width and then can be vectorized once it is decomposed into 1D convolution.

This patch https://reviews.llvm.org/D145160 adds vector support for linalg.conv_1d operation and thereby allowing us to vectorize linalg.conv_2d operation after proper tiling.
