[RuntimeDyld][ORC] Add support for Thumb mode to RuntimeDyldMachOARM. This patch adds support for thumb relocations to RuntimeDyldMachOARM, and adds a target-specific flags field to JITSymbolFlags (so that on ARM we can record whether each symbol is Thumb-mode code). RuntimeDyldImpl::emitSection is modified to ensure that stubs memory is correctly aligned based on the size returned by getStubAlignment(). llvm-svn: 310517

[RuntimeDyld][MachO] Properly handle thumb to thumb calls within a section. Previously thumb bits were only checked for external relocations (thumb to arm code and vice-versa). This patch adds detection for thumb callees in the same section asthe (also thumb) caller. The MachO/Thumb test case is updated to cover this, and redundant checks (handled by the MachO/ARM test) are removed. llvm-svn: 331838

Simplify decoupling between RuntimeDyld/RuntimeDyldChecker, add 'got_addr' util. This patch reduces the number of functions in the interface between RuntimeDyld and RuntimeDyldChecker by combining "GetXAddress" and "GetXContent" functions into "GetXInfo" functions that return a struct describing both the address and content. The GetStubOffset function is also replaced with a pair of utilities, GetStubInfo and GetGOTInfo, that fit the new scheme. For RuntimeDyld both of these functions will return the same result, but for the new JITLink linker (https://reviews.llvm.org/D58704) these will provide the addresses of PLT stubs and GOT entries respectively. For JITLink's use, a 'got_addr' utility has been added to the rtdyld-check language, and the syntax of 'got_addr' and 'stub_addr' has been changed: both functions now take two arguments, a 'stub container name' and a target symbol name. For llvm-rtdyld/RuntimeDyld the stub container name is the object file name and section name, separated by a slash. E.g.: rtdyld-check: *{8}(stub_addr(foo.o/__text, y)) = y For the upcoming llvm-jitlink utility, which creates stubs on a per-file basis rather than a per-section basis, the container name is just the file name. E.g.: jitlink-check: *{8}(got_addr(foo.o, y)) = y llvm-svn: 358295
