parameters. Examples of these are: struct { } a; union { } b[256]; int a[0]; An empty aggregate has an address, although dereferencing that address is pointless. When passed as a parameter, an empty aggregate does not consume a protocol register, nor does it consume a doubleword in the parameter save area. Passing an empty aggregate by reference passes an address just as for any other aggregate. Returning an empty aggregate uses GPR3 as a hidden address of the return value location, just as for any other aggregate. The patch modifies PPCTargetLowering::LowerFormalArguments_64SVR4 and PPCTargetLowering::LowerCall_64SVR4 to properly skip empty aggregate parameters passed by value. The handling of return values and by-reference parameters was already correct. Built on powerpc64-unknown-linux-gnu and tested with no new regressions. A test case is included to test proper handling of empty aggregate parameters on both sides of the function call protocol. llvm-svn: 167090

This patch migrates the stpcpy optimizations from the simplify-libcalls pass into the instcombine library call simplifier. Note that the __stpcpy_chk simplifications were migrated in a previous commit. llvm-svn: 167083

r166198 migrated the strcpy optimization to instcombine. The strcpy simplifier that was migrated from Transforms/Scalar/SimplifyLibCalls.cpp was also doing some __strcpy_chk simplifications. Those fortified simplifications were migrated as well, but introduced a bug in the __stpcpy_chk simplifier in the process. This happened because the __strcpy_chk and __stpcpy_chk simplifiers were both mapped to StrCpyChkOpt which was updated with simplifications that worked for __strcpy_chk, but not __stpcpy_chk. This patch fixes the problem by adding proper test coverage and creating a new simplifier for __stpcpy_chk (instead of sharing one with __strcpy_chk). llvm-svn: 167082

<rdar://problem/12586188> Make ImportError a special case for "command script import", such that the error message for the exception becomes the error for the entire import operation and silence the backtrace printout In the process, refactor the Execute* commands in ScriptInterpreter to take an options object, and add a new setting to not mask out errors so that the callers can handle them directly instead of having the default behavior llvm-svn: 167067

RegisterContextKDP_i386 was not correctly writing registers due to missing "virtual" keywords. Added the virtual keywords and made the functions pure virtual to ensure subclasses can't get away without implementing these functions. llvm-svn: 167066

Instead of recomputing relative pointer information just prior to fusing, cache this information (which also needs to be computed during the candidate-pair selection process). This cuts down on the total number of SE queries made, and also is a necessary intermediate step on the road toward including shuffle costs in the pair selection procedure. No functionality change is intended. llvm-svn: 167049
