[ExecutionEngine] Remove unused includes (NFC) (#116749)

2024-11-20T03:41:59+00:00

Identified with misc-include-cleaner.

[IR] Add getDataLayout() helpers to Function and GlobalValue (#96919)

2024-06-28T06:36:49+00:00

Similar to https://github.com/llvm/llvm-project/pull/96902, this adds
`getDataLayout()` helpers to Function and GlobalValue, replacing the
current `getParent()->getDataLayout()` pattern.

[ORC] Add MaterializationUnit::Interface parameter to ObjectLayer::add.

2021-12-15T01:03:55+00:00

Also moves object interface building functions out of Mangling.h and in to the
new ObjectFileInterfaces.h header, and updates the llvm-jitlink tool to use
custom object interfaces rather than a custom link layer.

ObjectLayer::add overloads are added to match the old signatures (which
do not take a MaterializationUnit::Interface). These overloads use the
standard getObjectFileInterface function to build an interface.

Passing a MaterializationUnit::Interface explicitly makes it easier to alter
the effective interface of the object file being added, e.g. by changing symbol
visibility/linkage, or renaming symbols (in both cases the changes will need to
be mirrored by a JITLink pass at link time to update the LinkGraph to match the
explicit interface). Altering interfaces in this way can be useful when lazily
compiling (e.g. for renaming function bodies) or emulating linker options (e.g.
demoting all symbols to hidden visibility to emulate -load_hidden).

[ORC] Add a MaterializationUnit::Interface struct.

2021-12-08T02:41:15+00:00

MaterializationUnit::Interface holds the values that make up the interface
(for ORC's purposes) of a materialization unit: the symbol flags map and
initializer symbol.

Having a type for this will make functions that build materializer interfaces
more readable and maintainable.

[ORC][ORC-RT] Reapply "Introduce ELF/*nix Platform and runtime..." with fixes.

2021-08-27T04:41:58+00:00

This reapplies e256445bfff, which was reverted in 45ac5f54418 due to bot errors
(e.g. https://lab.llvm.org/buildbot/#/builders/112/builds/8599). The issue that
caused the bot failure was fixed in 2e6a4fce356.

[ORC][JITLink][ELF] Treat STB_GNU_UNIQUE as Weak in the JIT.

2021-08-27T04:41:28+00:00

This should fix the bot error in
https://lab.llvm.org/buildbot/#/builders/112/builds/8599
which forced reversion of the ELFNixPlatform in 45ac5f54418.

This should allow us to re-enable the ELFNixPlatform in a follow-up patch.

Revert "[ORC-RT][ORC] Introduce ELF/*nix Platform and runtime support."

2021-08-18T10:42:23+00:00

This reverts commit e256445bfff12013c3c4ad97da4aa69d25b175b5.

This commit broke some of the bots (see e.g.
https://lab.llvm.org/buildbot/#/builders/112/builds/8599). Reverting while I
investigate.

[ORC-RT][ORC] Introduce ELF/*nix Platform and runtime support.

2021-08-18T05:00:22+00:00

This change adds support to ORCv2 and the Orc runtime library for static
initializers, C++ static destructors, and exception handler registration for
ELF-based platforms, at present Linux and FreeBSD on x86_64. It is based on the
MachO platform and runtime support introduced in bb5f97e3ad1.

Patch by Peter Housel. Thanks very much Peter!

[ORC][ORC-RT] Add initial Objective-C and Swift support to MachOPlatform.

2021-07-26T08:02:01+00:00

This allows ORC to execute code containing Objective-C and Swift classes and
methods (provided that the language runtime is loaded into the executor).

[Object] Change uint32_t getSymbolFlags() to Expected getSymbolFlags().

2020-04-18T13:27:57+00:00

This change enables getSymbolFlags() to return errors which benefit error reporting in clients.
