This will eventually be required for C++. It is also, apparently,
required for anonymous structs that are used as the type of a
named field.
Should unblock the Linux Foundation build.
initialization in-place on demand. Initialize parent metadata
references correctly on struct and enum metadata.
Also includes several minor improvements related to relative
pointers that I was using before deciding to simply switch the
parent reference to an absolute reference to get better access
patterns.
Includes a fix since the earlier commit to make enum metadata
writable if they have an unfilled payload size. This didn't show
up on Darwin because "constant" is currently unenforced there in
global data containing relocations.
This patch requires an associated LLDB change which is being
submitted in parallel.
Eventually, we decided to do this
1. Have the function signature opts (used to be called the cloner to create
the optimized function.
2. Mark the thunk as always_inline
3. Rely on the inliner to inline the thunk to get the benefit of calling optimized
function directly.
This is a small helper library to communicate information back to
swift-reflection-test from a test swift executable. Each swift test
file under test/Reflection should link this library to get the main
test hook to send responses back to the test tool.
fulfillments, because we don't actually fill them in.
This is a minimal, temporary, speculative fix for the failure
described in rdar://25069637, for which I unfortunately do not have
a minimal test case and which I have been unable to duplicate in
my own testing due to various language restrictions that I hope
to lift given the better (but temporarily reverted) fix.
We decided to use the inliner to rewrite the caller's callsites.
And eventually I will turn FunctionSignatureAnalysis into a Utility.
As its data should only be used and kept in the cloner pass.
This forces the callsites to be rewritten by the inliner.
we have the issue that the thunk changes from the time the its created to
the time its reread to figure out what we have done to the original function
This results in missed opportunities.
This solution solves the problem gracefully, because the thunk carries the information
on how to set up the call to the optimized functions.
Inlining the thunk makes the callsite calling the optimized function for free. i.e.
without any rewriting.
I did not measure any regression with this change.
