Subject: [MCJIT] Replace memcpy with readBytesUnaligned in RuntimeDyldMachOI386.
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=458b495075da02286d068f61b240ee9c8d4cd027;p=oota-llvm.git

[MCJIT] Replace memcpy with readBytesUnaligned in RuntimeDyldMachOI386.

This should fix the failures of the MachO_i386_DynNoPIC_relocations.s test case
on MIPS hosts.
