The getMachODefaultTextSection and getMachODefaultRWDataSection functions
return the "__TEXT,__text" and "__DATA,__data" sections respectively, creating
empty sections if the default sections are not already present in the graph.
These functions can be used by utilities that want to add code or data to these
standard sections (e.g. these functions can be used to supply the section
argument to the createAnonymousPointerJumpStub and
createPointerJumpStubBlock functions in the various targets).
Note that llvm::support::endianness has been renamed to
llvm::endianness while becoming an enum class as opposed to an
enum. This patch replaces support::{big,little,native} with
llvm::endianness::{big,little,native}.
If JITLinkGeneric::linkPhase2 receives an Error rather than an InFlightAlloc
then we need to call JITLinkContext::notifyFailed, rather than calling
abandonAllocAndBailOut -- the latter asserts that there is an allocation to
abandon, and this was turning allocation errors into assertion failures in
debug mode.
