[llvm][CodeGen] Avoid 'raw_string_ostream::str' (NFC) (#97318)

2024-07-02T01:52:37+00:00

Since `raw_string_ostream` doesn't own the string buffer, it is
desirable (in terms of memory safety) for users to directly reference
the string buffer rather than use `raw_string_ostream::str()`.

Work towards TODO comment to remove `raw_string_ostream::str()`.

Revert "[CodeGen] Place SDNode debug ID declaration under appropriate #if"

2022-04-06T17:32:53+00:00

This reverts commit 83a798d4b0e17ac41d5430f1290d3661343eee1e.

As discussed in D120714 with @thakis, the patch added unneeded complexity
without noticeable benefits.

[CodeGen] Place SDNode debug ID declaration under appropriate #if

2022-04-06T11:09:32+00:00

Place PersistentId declaration under #if LLVM_ENABLE_ABI_BREAKING_CHECKS to
reduce memory usage when it is not needed.

[CodeGen] Define ABI breaking class members correctly

2022-03-24T09:42:59+00:00

Non-static class members declared under #ifndef NDEBUG should be declared
under #if LLVM_ENABLE_ABI_BREAKING_CHECKS to make headers library-friendly and
allow cross-linking, as discussed in D120714.

[SelectionDAG] Drop unnecessary const from a return type (NFC)

Utility to dump .dot representation of SelectionDAG without firing viewer

2020-06-04T06:21:48+00:00

Summary:
This patch adds support for dumping .dot
representation of SelectionDAG. It is inspired from the fact that,
a developer may want to just dump the graph at
a predictable path with a simple name to compare.
The exisitng utility (i.e. viewGraph) are overkill
for this motive hence this patch adds the requires support
while using the core routines from GraphWriter.

Example usage: DAG.dumpDotGraph("/tmp/graph.dot", "MyGraph")
will create /tmp/graph.dot file when DAG is an
object of SelectionDAG class.

Make llvm::StringRef to std::string conversions explicit.

2020-01-28T22:25:25+00:00

This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.

This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.

This doesn't actually modify StringRef yet, I'll do that in a follow-up.

Update the file headers across all of the LLVM projects in the monorepo

2019-01-19T08:50:56+00:00

to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Rename DEBUG macro to LLVM_DEBUG.

2018-05-14T12:53:11+00:00

    
The DEBUG() macro is very generic so it might clash with other projects.
The renaming was done as follows:
- git grep -l 'DEBUG' | xargs sed -i 's/\bDEBUG\s\?(/LLVM_DEBUG(/g'
- git diff -U0 master | ../clang/tools/clang-format/clang-format-diff.py -i -p1 -style LLVM
- Manual change to APInt
- Manually chage DOCS as regex doesn't match it.

In the transition period the DEBUG() macro is still present and aliased
to the LLVM_DEBUG() one.
