Mips.abiflags is a new implicitly generated section that will be present on all new modules. The section contains a versioned data structure which represents essentially information to allow a program loader to determine the requirements of the application. This patch implements mips.abiflags section and provides test cases for it. llvm-svn: 212519

[mips] Correct .MIPS.abiflags for -mfpxx on MIPS32r6 Summary: The cpr1_size field describes the minimum register width to run the program rather than the size of the registers on the target. MIPS32r6 was acting as if -mfp64 has been given because it starts off with 64-bit FPU registers. Differential Revision: http://reviews.llvm.org/D4538 llvm-svn: 213243

[mips] Don't derive the default ABI from the CPU in the backend. Summary: The backend has no reason to behave like a driver and should generally do as it's told (and error out if it can't) instead of trying to figure out what the API user meant. The default ABI is still derived from the arch component as a concession to backwards compatibility. API-users that previously passed an explicit CPU and a triple that was inconsistent with the CPU (e.g. mips-linux-gnu and mips64r2) may get a different ABI to what they got before. However, it's expected that there are no such users on the basis that CodeGen has been asserting that the triple is consistent with the selected ABI for several releases. API-users that were consistent or passed '' or 'generic' as the CPU will see no difference.
