* Do not generate by TableGen the hard-coded standard, target-independent part ofRoman Levenstein2008-05-141-140/+3
| | | | | | | | | | | | | | | DAG instruction selectors. Introudce a dedicated header file for this part: include/llvm/CodeGen/DAGISelHeader.h TableGen now only generates the include preprocessor directive to include this new header. This is a preparation for supporting multiple implementations of instruction selectors in the future. Reviewed and approved by Evan and Dan. llvm-svn: 51102
* Filter option names to escape symbols not allowed as C++ identifiers.Mikhail Glushenkov2008-05-121-5/+22
| | | | | | | Makes it possible to use options with names like "Wa,". Also fixes the -Wall option handling as a side-effect. llvm-svn: 50973

| | | | | | | 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. llvm-svn: 49433

* Move instruction flag inference out of InstrInfoEmitter and intoDan Gohman2008-04-038-152/+163
| | | | | | | | | | | | 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. llvm-svn: 49123
* Add new CC lowering rule: provide a list of registers, which can be 'shadowed',Anton Korobeynikov2008-04-021-0/+42

* Change the MemoryBuffer::getFile* methods to take just a pointer to theChris Lattner2008-04-012-4/+3

* Add first proof-of-concept universal compiler driver framework basedAnton Korobeynikov2008-03-233-1/+973
| | | | | | | | | 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. llvm-svn: 48699
* Introduce a new node for holding call argumentDuncan Sands2008-03-211-4/+4
| | | | | | | | | | | | | | | | | 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. llvm-svn: 48640

* Make insert_subreg a two-address instruction, vastly simplifying ↵Christopher Lamb2008-03-163-5/+16
| | | | | | 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. llvm-svn: 48412

* Get rid of a pseudo instruction and replace it with subreg based operation ↵Christopher Lamb2008-03-131-11/+6
| | | | | | | 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. llvm-svn: 48329

* Increase ISD::ParamFlags to 64 bits. Increase the ByValSizeDale Johannesen2008-03-101-2/+2
| | | | | | | | | | 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.) llvm-svn: 48122
