[Mips] Convert a GNU style Mips ABI name to the name accepted by LLVM Mips backend. llvm-svn: 179981
2013-04-21 21:30:10 +08:00
// Check passing Mips ABI options to the backend.
//
[Driver][Mips] If ABI name is not provided deduce it from the target triple not from the CPU name. This approach is closer to the method used by gcc driver. llvm-svn: 212176

[mips] Defer validity check for CPU/ABI pairs and improve error message for invalid cases. Summary: The validity of ABI/CPU pairs is no longer checked on the fly but is instead checked after initialization. As a result, invalid CPU/ABI pairs can be reported as being known but invalid instead of being unknown. For example, we now emit: error: ABI 'n32' is not supported on CPU 'mips32r2' instead of: error: unknown target ABI 'n64' Reviewers: atanasyan Subscribers: sdardis, cfe-commits Differential Revision: http://reviews.llvm.org/D21023 llvm-svn: 272645

[mips] The default ABI depends on the CPU not the Arch on MTI and IMG vendor triples. Summary: 32-bit CPU's default to O32. 64-bit CPU's default to N64. The default CPU (mips32r2/mips64r2) still depends on the arch so there's no functional change when the CPU isn't specified but commands like: clang -target mips-mti-linux-gnu -mips64r2 will now default to a 64-bit ABI like our gcc toolchains do* instead of asserting in the backend**. Other vendors (including Triple::UnknownVendor) still derive the default ABI from the arch. * Although not the same one as our gcc toolchains, clang has historically defaulted to N64 where gcc defaults to N32. ** Mixing O32 and a 64-bit CPU causing assertions is a long-standing bug.
