Remove compile time PreserveName in favor of a runtime cc1 -discard-value-names option Summary: This flag is enabled by default in the driver when NDEBUG is set. It is forwarded on the LLVMContext to discard all value names (but GlobalValue) for performance purpose. This an improved version of D18024 Reviewers: echristo, chandlerc Subscribers: cfe-commits Differential Revision: http://reviews.llvm.org/D18127 From: Mehdi Amini <mehdi.amini@apple.com> llvm-svn: 263394

[mips] Fix handling of GNUABIN32 environment in a target triple The `GNUABIN32` environment in a target triple implies using the N32 ABI. This patch adds support for this environment and switches on N32 ABI if necessary. Patch by Patch by YunQiang Su. Differential revision: https://reviews.llvm.org/D51464 llvm-svn: 344570

[mips] Zero-sized structs cannot be ignored in MipsABIInfo::classifyReturnType() for O32 Summary: They are returned indirectly which causes the other arguments to move to the next argument slot. With this, utils/ABITest does not discover any failing cases in the first 500 attempts on big/little endian for O32. Previously some of these failed. Also tested N32/N64 little endian (big endian has other known issues) with no issues.
