2012-06-28Refactor operation equivalence checking in BBVectorize by extending ↵Hal Finkel
Instruction::isSameOperationAs. Maintaining this kind of checking in different places is dangerous, extending Instruction::isSameOperationAs consolidates this logic into one place. Here I've added an optional flags parameter and two flags that are important for vectorization: CompareIgnoringAlignment and CompareUsingScalarTypes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159329 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-28Remove 'site.exp' building from both CMake and configure+make.Chandler Carruth
This is another vestige of the DejaGNU roots. There were FIXMEs in the lit setup to add a 'lit.site.cfg', which has been around for quite some time now, so I've properly switched the handling of the 4 things actually used in site.exp to go through lit.site.cfg now. No more parsing of the .exp file, one fewer configure-style generated file, etc., etc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159313 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-27The ELF relocation record format is different for N64 Jack Carter
which many Mips 64 ABIs use than for O64 which many if not all other target ABIs use. Most architectures have the following 64 bit relocation record format: typedef struct { Elf64_Addr r_offset; /* Address of reference */ Elf64_Xword r_info; /* Symbol index and type of relocation */ } Elf64_Rel; typedef struct { Elf64_Addr r_offset; Elf64_Xword r_info; Elf64_Sxword r_addend; } Elf64_Rela; Whereas N64 has the following format: typedef struct { Elf64_Addr r_offset;/* Address of reference */ Elf64_Word r_sym; /* Symbol index */ Elf64_Byte r_ssym; /* Special symbol */ Elf64_Byte r_type3; /* Relocation type */ Elf64_Byte r_type2; /* Relocation type */ Elf64_Byte r_type; /* Relocation type */ } Elf64_Rel; typedef struct { Elf64_Addr r_offset;/* Address of reference */ Elf64_Word r_sym; /* Symbol index */ Elf64_Byte r_ssym; /* Special symbol */ Elf64_Byte r_type3; /* Relocation type */ Elf64_Byte r_type2; /* Relocation type */ Elf64_Byte r_type; /* Relocation type */ Elf64_Sxword r_addend; } Elf64_Rela; The structure is the same size, but the r_info data element is now 5 separate elements. Besides the content aspects, endian byte reordering will be different for the area with each element being endianized separately. I treat this as generic and continue to pass r_type as an integer masking and unmasking the byte sized N64 values for N64 mode. I've implemented this and it causes no affect on other current targets. This passes make check. Jack git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159299 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-27Some reassociate optimizations create new instructions, which they insert justDuncan Sands
before the expression root. Any existing operators that are changed to use one of them needs to be moved between it and the expression root, and recursively for the operators using that one. When I rewrote RewriteExprTree I accidentally inverted the logic, resulting in the compacting going down from operators to operands rather than up from operands to the operators using them, oops. Fix this, resolving PR12963. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159265 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-27Clean up the 'check' CMake build rule a bit, notable renaming it toChandler Carruth
'check-llvm'. Don't worry! 'check' still works! =] To rationalize the names of targets used to run tests, the vague plan is the following: make check-llvm # run LLVM reg/unit tests (currently 'check') make check-clang # run Clang reg/unit tests (currently 'clang-test') make check-rt # run CompilerRT reg/unit tests make check-asan # run ASan reg/unit tests (subset of -rt) make check-tsan # run TSan reg/unit tests (subset of -rt) make check-all # run as much of the above as is available The last one respects what projects are checked out and built for a given tree. Personally, I would like to eventually make 'check' be an alias for 'check-all'. For now however, it is an alias for 'check-llvm', and thus no behavior has changed. While this patch and my plan only really apply to CMake, I think it might be good to similarly rationalize the naming scheme for the Make builds. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159258 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-26Remove a instcombine transform that (no longer?) makes sense:Evan Cheng
// C - zext(bool) -> bool ? C - 1 : C if (ZExtInst *ZI = dyn_cast<ZExtInst>(Op1)) if (ZI->getSrcTy()->isIntegerTy(1)) return SelectInst::Create(ZI->getOperand(0), SubOne(C), C); This ends up forming sext i1 instructions that codegen to terrible code. e.g. int blah(_Bool x, _Bool y) { return (x - y) + 1; } => movzbl %dil, %eax movzbl %sil, %ecx shll $31, %ecx sarl $31, %ecx leal 1(%rax,%rcx), %eax ret Without the rule, llvm now generates: movzbl %sil, %ecx movzbl %dil, %eax incl %eax subl %ecx, %eax ret It also helps with ARM (and pretty much any target that doesn't have a sext i1 :-).

2012-06-26There are a number of generic inline asm operand modifiers thatJack Carter
up to r158925 were handled as processor specific. Making them generic and putting tests for these modifiers in the CodeGen/Generic directory caused a number of targets to fail. This commit addresses that problem by having the targets call the generic routine for generic modifiers that they don't currently have explicit code for.

2012-06-26Replacing zero-sized alloca's with a null pointer is too aggressive, insteadDuncan Sands
merge all zero-sized alloca's into one, fixing c43204g from the Ada ACATS conformance testsuite. What happened there was that a variable sized object was being allocated on the stack, "alloca i8, i32 %size". It was then being passed to another function, which tested that the address was not null (raising an exception if it was) then manipulated %size bytes in it (load and/or store). The optimizers cleverly managed to deduce that %size was zero (congratulations to them, as it isn't at all obvious), which made the alloca zero size, causing the optimizers to replace it with null, which then caused the check mentioned above to fail, and the exception to be raised, wrongly. Note that no loads and stores were actually being done to the alloca (the loop that does them is executed %size times, i.e. is not executed), only the not-null address check. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159202 91177308-0d34-0410-b5e6-96231b3b80d8
