Remove `br i1 undef` from some regression tests [NFC] (#115130)

2024-11-07T08:11:15+00:00

As defined in LangRef, branching on `undef` is undefined behavior.
This PR aims to remove undefined behavior from tests. As UB tests break
Alive2 and may be the root cause of breaking future optimizations.

Here's an Alive2 proof for one of the examples:

[Orc][examples] Revisit advanced LLJIT examples and tests (#76236)

2024-01-03T08:51:18+00:00

Some maintenance on implementation and tests:
* Drop manual TargetMachineBuilder setup
* Drop addDebugSupport() in favor of Orc's enableDebuggerSupport()
* Check that debug support plugins append jit_code_entry
* Update and reduce sample input

[Orc][examples] Drop target triple from input for remote debugging test (#74831)

2023-12-08T21:10:03+00:00

https://github.com/llvm/llvm-project/pull/74764 reported that the
`lljit-with-remote-debugging` test fails on AArch64 hosts, because the
input IR file states arch x86_64 explicitly. In order to drop the target
triple we have to remove a check in the example implementation.

Not sure it's fully portable now, but at least it's better than before.

[ExecutionEngine] Re-enable JIT tests on PowerPC.

2023-05-21T23:12:06+00:00

These were previously re-enabled in d771f54107c, but had to be disabled again
in 2060a72b4d7 due to test failures.

This is a next step to landing https://reviews.llvm.org/D148192, which adds
a skeleton JITLink backend for PowerPC.

The fixes for those failures were (1) to explicitly specify IsLittleEndian =
true for the MachO YAML testcases, (2) disable some example tests for examples
that aren't supported on PowerPC yet, and (3) fixing the endianness of a
relocation read/write (for ELF R_AARCH64_TSTBR14) in RuntimeDyldELF.

[NFC][Py Reformat] Reformat lit.local.cfg python files in llvm

2023-05-17T15:03:15+00:00

This is a follow-up to b71edfaa4ec3c998aadb35255ce2f60bba2940b0
since I forgot the lit.local.cfg files in that one.

Reformatting is done with `black`.

If you end up having problems merging this commit because you
have made changes to a python file, the best way to handle that
is to run git checkout --ours  and then reformat it
with black.

If you run into any problems, post to discourse about it and
we will try to help.

[LegacyPM] Port example pass SimplifyCFG to new PM

2023-01-10T23:42:01+00:00

This is part of effort in removing -enable-new-pm flag.
As a prat of this effort one of example passes SimplifyCFG must
be ported to new PM which will allow to remove the flag
calls from the tests that are using this pass.
