* Fix illegal DAG produced by SelectionDAG::getConstant() for v2i64 typeDaniel Sanders2013-11-153-60/+143
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: When getConstant() is called for an expanded vector type, it is split into multiple scalar constants which are then combined using appropriate build_vector and bitcast operations. In addition to the usual big/little endian differences, the case where the element-order of the vector does not have the same endianness as the elements themselves is also accounted for. For example, for v4i32 on big-endian MIPS, the byte-order of the vector is <3210,7654,BA98,FEDC>. For little-endian, it is <0123,4567,89AB,CDEF>. Handling this case turns out to be a nop since getConstant() returns a splatted vector (so reversing the element order doesn't change the value) This fixes a number of cases in MIPS MSA where calling getConstant() during operation legalization introduces illegal types (e.g. to legalize v2i64 UNDEF into a v2i64 BUILD_VECTOR of illegal i64 zeros). It should also handle bigger differences between illegal and legal types such as legalizing v2i64 into v8i16. lowerMSASplatImm() in the MIPS backend no longer needs to avoid calling getConstant() so this function has been updated in the same patch. For the sake of transparency, the steps I've taken since the review are: * Added 'virtual' to isVectorEltOrderLittleEndian() as requested. This revealed that the MIPS tests were falsely passing because a polymorphic function was not actually polymorphic in the reviewed patch. * Fixed the tests that were now failing. This involved deleting the code to handle the MIPS MSA element-order (which was previously doing an byte-order swap instead of an element-order swap). This left isVectorEltOrderLittleEndian() unused and it was deleted. * Fixed build failures caused by rebasing beyond r194467-r194472. These build failures involved the bset, bneg, and bclr instructions added in these commits using lowerMSASplatImm() in a way that was no longer valid after this patch. Some of these were fixed by calling SelectionDAG::getConstant() instead, others were fixed by a new function getBuildVectorSplat() that provided the removed functionality of lowerMSASplatImm() in a more sensible way.

* R600: Fix scheduling of instructions that use the LDS output queueTom Stellard2013-11-159-51/+116
| | | | | | | | | | | | | | | | | | | | | | | | The LDS output queue is accessed via the OQAP register. The OQAP register cannot be live across clauses, so if value is written to the output queue, it must be retrieved before the end of the clause. With the machine scheduler, we cannot statisfy this constraint, because it lacks proper alias analysis and it will mark some LDS accesses as having a chain dependency on vertex fetches. Since vertex fetches require a new clauses, the dependency may end up spiltting OQAP uses and defs so the end up in different clauses. See the lds-output-queue.ll test for a more detailed explanation. To work around this issue, we now combine the LDS read and the OQAP copy into one instruction and expand it after register allocation. This patch also adds some checks to the EmitClauseMarker pass, so that it doesn't end a clause with a value still in the output queue and removes AR.X and OQAP handling from the scheduler (AR.X uses and defs were already being expanded post-RA, so the scheduler will never see them).

| | | | | | | | | | This comes into play with patchpoint, which can fold multiple operands.

* Error if we see an alias to a declaration.Rafael Espindola2013-11-141-0/+5
| | | | | | | | | | | | | | | In ELF and COFF an alias is just another offset in a section. There is no way to represent an alias to something in another file. In MachO, the spec has the N_INDR type which should allow for exactly that, but is not currently implemented. Given that it is specified but not implemented, we error in codegen to avoid miscompiling but don't reject aliases to declarations in the verifier to leave the option open of implementing it. In the past we have used alias to declarations as a way of implementing weakref, which is why it exists in some old tests which this patch updates. llvm-svn: 194705

| | | | | | | | | | | | | | | | | | | MemorySanitizer. Indirect call wrapping helps MSanDR (dynamic instrumentation companion tool for MSan) to catch all cases where execution leaves a compiler-instrumented module by allowing the tool to rewrite targets of indirect calls. This change is an optimization that skips wrapping for calls when target is inside the current module. This relies on the linker providing symbols at the begin and end of the module code (or code + data, does not really matter). Gold linker provides such symbols by default. GNU (BFD) linker needs a link flag: -Wl,--defsym=__executable_start=0. More info: https://code.google.com/p/memory-sanitizer/wiki/MSanDR#Native_exec llvm-svn: 194697
