After linking runtime, llvm-ir is modified to add checker function
call at all points where unknown function, which can possibly run long
is called. This function checks Native state is set, to avoid long locks
at gc.
By default, C functions compiled to bitcode by clang have the
nounwind attribute. If such functions throws an exception, the
behaviour is undefined.
Our interop machinery can process foreign exceptions on call sites
(terminate or wrap them in Kotlin exceptions). But if the interop
bridges have the nounwind attribute, LLVM optimizations (particularly
inlining) may lead to the situation when a foreign exception is ignored by
our foreign exception handler.
This patch fixes the issue by compiling bridges with -fexceptions flag.
This flag makes clang to not set the nounwind attribute, so exceptions
can be thrown through C frames.
FileSignature, CompositeSignature, LocalSignature
They are needed to make possible reference any non-local declaration via
signature, including private signature, type parameters and so on.
- Support those new signatures in proto and klibs
- Rename `isPublic` -> `isPubliclyVisible` due to changed semantic
- Fix FIR
- clean up code
Previously they were skipped, and this was an incorrect optimization:
even if super class implements the interface too, this doesn't mean
that virtual adapters provided by that interface are inherited
by non-exported subclass that needs them;
for example, this doesn't happen when the super class is exported
(i.e. Obj-C class is not created at runtime).
Remove incorrect optimization instead of making it more sophisticated,
because it is useless anyway.
^KT-46431 Fixed
The new GC will require threads to suspend right after registering
if Stop-The-World is requested. This patch changes the initial
thread state to kNative and adds a separate state switch right
after thread registering. This switch suspends if it is necessary.
Create an explicit list of targets that have unstable compiler caches
in konan.properties. It allows to control all lists of cacheable targets
in a single place.
