This allows optionals to be serialized and deserialized, and used as arguments
and return values in SPS wrapper functions.
Serialization of optional values is indicated by use of the SPSOptional tag.
SPSOptionals are serialized serialized as a bool (false for no value, true for
value) plus the serialization of the contained value if any. Serialization
to/from std::optional is included in this commit.
This commit includes updates to SimplePackedSerialization in both ORC and the
ORC runtime.
, std::optional serialization.
This is a counterpart to llvm::orc::SymbolStringPool. It holds uniqued,
ref-counted strings; and can be used to avoid redundant storage of strings,
and speed up comparison of strings held in the pool (these become pointer
comparisons).
Serialized calls to void-wrapper-functions should have zero bytes of argument
data, but accessing ArgData[0] may (and will, in the case of SmallVector) fail
if the argument data buffer is empty.
This commit fixes the issue by adding a check for empty argument buffers.
We want to move functionality from the LLVM ORCTargetProcess library into the
ORC runtime, and this will mean implementing remote-executor testing tools
(like llvm-jitlink-executor and lli-child-target) in the ORC runtime.
This patch refactors the ORC runtime build system to introduce an
add_orc_tool function that can be used to add new test tools. The code is
modeled on existing functions for adding unit tests.
A placeholder orc-rt-executor tool and test are added to verify that the
config changes behave as expected.
