Description
When bootstrapping stage0 -> stage1 with preset bootstrap_stage0 and bootstrap_stage1 and extra-swift-cmake-options=-DBRIDGING_MODE=PURE, the following error breaks the build:
SIL verification failed: public/package/shared function must have a body: F->isDefinition() || F->hasForeignBody()
...
4. While verifying SIL function "@$sSo5swiftO11EffectsKindVSYSCSY8rawValuexSg03RawE0Qz_tcfCTW".
Reverting commit 68bb4b3 seems to work around the issue.
Reproduction
Ensure that BRIDGING_MODE=PURE and bootstrap, for example:
./swift/utils/build-script --preset=bootstrap_stage0 build_subdir=bootstrap_stage0 install_destdir=toolchain_stage0
env PATH=<path to...>/toolchain_stage0/usr/bin/:$PATH ./swift/utils/build-script --preset=bootstrap_stage1 build_subdir=bootstrap_stage1 install_destdir=toolchain_stage1
