Reverts llvm/llvm-project#168921
Causes build failures.
|
|
Add declaration of command line options to BugDriver.h and remove extern
declarations in individual .cpp files.
|
|
- Move file local variables and functions out of anonymous namespace and
mark them static.
- Change a few function names to conform to LLVM coding standard
(camelCase).
- Add end of namespace comments for anonymous namespaces.

The build failed with
error: call to deleted constructor of 'llvm::Error'
errors.
This reverts commit 1c2241a7936bf85aa68aef94bd40c3ba77d8ddf2.

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.

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.

Summary:
When bugpoint attempts to find the other executables it needs to run,
such as `opt` or `clang`, it tries searching the user's PATH. However,
in many cases, the 'bugpoint' executable is part of an LLVM build, and
the 'opt' executable it's looking for is in that same directory.
Many LLVM tools handle this case by using the `Paths` parameter of
`llvm::sys::findProgramByName`, passing the parent path of the currently
running executable. Do this same thing for bugpoint. However, to
preserve the current behavior exactly, first search the user's PATH,
and then search for 'opt' in the directory containing 'bugpoint'.
Test Plan:
`check-llvm`. Many of the existing bugpoint tests no longer need to use the
`--opt-command` option as a result of these changes.

Summary: Revert r318459 which introduced a TempFile scoping bug.

While there, change a bunch of helper functions to take references to

This one requires a new small feature in TempFile: the ability to keep

The core of the change is supposed to be NFC, however it also fixes
what I believe was an undefined behavior when calling:
va_start(ValueArgs, Desc);
with Desc being a StringRef.

This replaces the threading of `std::string &Error` through all of
these APIs with checked Error returns instead. There are very few
places here that actually emit any errors right now, but threading the
APIs through will allow us to replace a bunch of exit(1)'s that are
scattered through this code with proper error handling.
This is more or less NFC, but does move around where a couple of error
messages are printed out.

I'm going to clean up the APIs here a bit and touch many many lines
anyway.

We now use clang by default and fallback to gcc when requested.
With this commit, names reflect reality. No functional change

We now rely on gcc only if either of the following is true:
1) -gcc option is passed by the user
2) clang is not found in the default path.

sys::fs::createUniqueFile returns an absolute path, so MakeSharedObject does
too and we don't need to add a './' prefix.

This function is complementary to createTemporaryFile. It handles the case were
the unique file is *not* temporary: we will rename it in the end. Since we
will rename it, the file has to be in the same filesystem as the final
destination and we don't prepend the system temporary directory.
This has a small semantic difference from unique_file: the default mode is 0666.
This matches the behavior of most unix tools. For example, with this change
lld now produces files with the same permissions as ld. I will add a test
of this change when I port clang over to createUniqueFile (next commit).

sys::fs::unique_file will now loop infinitely if provided with a file name
without '%' characters and the input file already exists. As a result, bugpoint
cannot use a fixed file name for the execution output (including the reference
output).

This change allows bugpoint to pinpoint the "opt" pass and bitcode
segment responsible for a crash caused by miscompilation. At least it
works well for me now, without having to create any custom execution
wrappers.
