[IR] Enable opaque pointers by default

2022-06-02T07:40:56+00:00

This enabled opaque pointers by default in LLVM. The effect of this
is twofold:

* If IR that contains *neither* explicit ptr nor %T* types is passed
  to tools, we will now use opaque pointer mode, unless
  -opaque-pointers=0 has been explicitly passed.
* Users of LLVM as a library will now default to opaque pointers.
  It is possible to opt-out by calling setOpaquePointers(false) on
  LLVMContext.

A cmake option to toggle this default will not be provided. Frontends
or other tools that want to (temporarily) keep using typed pointers
should disable opaque pointers via LLVMContext.

[ThinLTO] During module importing, close one source module before open

2021-03-30T21:37:29+00:00

another one for distributed mode.

Currently during module importing, ThinLTO opens all the source modules,
collect functions to be imported and append them to the destination module,
then leave all the modules open through out the lto backend pipeline. This
patch refactors it in the way that one source module will be closed before
another source module is opened. All the source modules will be closed after
importing phase is done. It will save some amount of memory when there are
many source modules to be imported.

Note that this patch only changes the distributed thinlto mode. For in
process thinlto mode, one source module is shared acorss different thinlto
backend threads so it is not changed in this patch.

Re-land Remove REQUIRES:shell from tests that pass for me on Windows

2019-09-10T20:15:45+00:00

This reverts r371497 (git commit 3d7e9ab7b9f8c53aa41420c54970f0fb421004a2)

Reorder `not` with `env` in these two tests so they pass:
  Driver/rewrite-map-in-diagnostics.c
  Index/crash-recovery-modules.m.

This will not be necessary after D66531 lands.

Revert Remove REQUIRES:shell from tests that pass for me on Windows

Remove REQUIRES:shell from tests that pass for me on Windows

2019-09-10T00:50:32+00:00

I see in the history for some of these tests REQUIRES:shell was used as
a way to disable tests on Windows because they are flaky there. I tried
not to re-enable such tests, but it's possible that I missed some and
this will re-enable flaky tests on Windows. If so, we should disable
them with UNSUPPORTED:system-windows and add a comment that they are
flaky there. So far as I can tell, the lit internal shell is capable of
running all of these tests, and we shouldn't use REQUIRES:shell as a
proxy for Windows.

[llvm-nm] Write "no symbol" output to stderr

2018-10-05T21:10:03+00:00

This matches the output of binutils' nm and ensures that any scripts
or tools that use nm and expect empty output in case there no symbols
don't break.
