The windows buildbot originally failed because the check expressions are evaluated as 64-bit values, even for 32-bit symbols. Fixed this by comparing bottom 32-bits of the expressions. The host/target endian mismatch issue is that it's invalid to read/write target values using a host pointer without taking care of endian differences between the target and host. Most (if not all) instances of reinterpret_cast<uint32_t*>() in the RuntimeDyld are examples of this bug. This has been fixed for Mips using the endian aware read/write functions. The original commits were: r238838: [mips] Add RuntimeDyld tests for currently supported O32 relocations. Reviewers: petarj, vkalintiris Reviewed By: vkalintiris Subscribers: vkalintiris, llvm-commits Differential Revision: http://reviews.llvm.org/D10126 r238844: [mips][mcjit] Add support for R_MIPS_PC32. Summary: This allows us to resolve relocations for DW_EH_PE_pcrel TType encodings in the exception handling LSDA. Also fixed a nearby typo.
