* DebugInfo: Partial implementation of DWARF type units.David Blaikie2013-11-197-41/+133
| | | | | | | | | | | | | | Emit DW_TAG_type_units into the debug_info section using compile unit headers. This is bogus/unusable by debuggers, but testable and provides more isolated review. Subsequent patches will include support for type unit headers and emission into the debug_types section, as well as comdat grouping the types based on their hash. Also the CompileUnit type will be renamed 'Unit' and relevant portions pulled out into respective CompileUnit and TypeUnit types. llvm-svn: 195166

| | | | | | | | | | | | | | | | | | This is the first step to fix pr17918. It extends the .section directive a bit, inspired by what the ELF one looks like. The problem with using linkonce is that given .section foo .linkonce.... .section foo .linkonce we would already have switched sections when getting to .linkonce. The cleanest solution seems to be to add the comdat information in the .section itself. llvm-svn: 195148

| | | | | | | | | | | | This change is incorrect. If you delete virtual destructor of both a base class and a subclass, then the following code: Base *foo = new Child(); delete foo; will not cause the destructor for members of Child class. As a result, I observe plently of memory leaks. Notable examples I investigated are: ObjectBuffer and ObjectBufferStream, AttributeImpl and StringSAttributeImpl. llvm-svn: 194997

* Fix illegal DAG produced by SelectionDAG::getConstant() for v2i64 typeDaniel Sanders2013-11-152-1/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
