2008-04-09Fix a bug where an incorrect bit mask would be generated if a target's last asmNate Begeman
string began at a power of 2 in the string index. For example, if "ret" started at position 16, the ret instruction would be assigned code 16, but the mask would be AsmChars[] + Code & 15, not Code & 31. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49433 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-03Move instruction flag inference out of InstrInfoEmitter and intoDan Gohman
CodeGenDAGPatterns, where it can be used in other tablegen backends. This allows the inference to be done for DAGISelEmitter so that it gets accurate mayLoad/mayStore/isSimpleLoad flags. This brings MemOperand functionality back to where it was before 48329. However, it doesn't solve the problem of anonymous patterns which expand to code that does loads or stores. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49123 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-01Change the MemoryBuffer::getFile* methods to take just a pointer to theChris Lattner
start of a filename, not a filename+length. All clients can produce a null terminated name, and the system api's require null terminated strings anyway. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49041 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-23Add first proof-of-concept universal compiler driver framework basedAnton Korobeynikov
on ideas mentioned in PR686. Written by Mikhail Glushenkov and contributed by Codedgers, Inc. Old llvmc will be removed soon after new one will have all its properties. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48699 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-21Introduce a new node for holding call argumentDuncan Sands
flags. This is needed by the new legalize types infrastructure which wants to expand the 64 bit constants previously used to hold the flags on 32 bit machines. There are two functional changes: (1) in LowerArguments, if a parameter has the zext attribute set then that is marked in the flags; before it was being ignored; (2) PPC had some bogus code for handling two word arguments when using the ELF 32 ABI, which was hard to convert because of the bogusness. As suggested by the original author (Nicolas Geoffray), I've disabled it for the moment. Tested with "make check" and the Ada ACATS testsuite. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48640 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-16Make insert_subreg a two-address instruction, vastly simplifying ↵Christopher Lamb
LowerSubregs pass. Add a new TII, subreg_to_reg, which is like insert_subreg except that it takes an immediate implicit value to insert into rather than a register. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48412 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-13Get rid of a pseudo instruction and replace it with subreg based operation ↵Christopher Lamb
on real instructions, ridding the asm printers of the hack used to do this previously. In the process, update LowerSubregs to be careful about eliminating copies that have side affects. Note: the coalescer will have to be careful about this too, when it starts coalescing insert_subreg nodes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48329 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-10Increase ISD::ParamFlags to 64 bits. Increase the ByValSizeDale Johannesen
field to 32 bits, thus enabling correct handling of ByVal structs bigger than 0x1ffff. Abstract interface a bit. Fixes gcc.c-torture/execute/pr23135.c and gcc.c-torture/execute/pr28982b.c in gcc testsuite (were ICE'ing on ppc32, quietly producing wrong code on x86-32.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48122 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-05This patch fixes a problem encountered by the CellSPU backend where variantsScott Michel
were being pruned in patterns where a variable was used more than once, e.g.: (or (and R32C:$rA, R32C:$rC), (and R32C:$rB, (not R32C:$rC))) In this example, $rC is used more than once and is actually significant to instruction selection pattern matching when commuted variants are produced. This patch scans the pattern's clauses and collects the variables, creating a set of variables that are used more than once. TreePatternNode::isIsomorphicTo() also understands that multiply-used variables are significant. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47950 91177308-0d34-0410-b5e6-96231b3b80d8
