* Now that predicates can be composed, simplify several ofDan Gohman2008-10-153-205/+135
| | | | | | | | | | | | | the predicates by extending simple predicates to create more complex predicates instead of duplicating the logic for the simple predicates. This doesn't reduce much redundancy in DAGISelEmitter.cpp's generated source yet; that will require improvements to DAGISelEmitter.cpp's instruction sorting, to make it more effectively group nodes with similar predicates together. llvm-svn: 57565

* Fix the .ll grammar rules to allow any type before an 'i32', not just anChris Lattner2008-10-151-32/+49
| | | | | | | integer type. Invalid things like 'float 42' are now rejected by the semantic analysis in the productions not the parser. This fixes PR2733. llvm-svn: 57560

* Eliminate the "IntType ::= INTTYPE" production, just use Chris Lattner2008-10-151-10/+9
| | | | | | INTTYPE everywhere. llvm-svn: 57558
* add a noteChris Lattner2008-10-151-0/+30
| | | | llvm-svn: 57557
* add support for folding immediates into stores when they Chris Lattner2008-10-151-20/+20
| | | | | | | are due to argument passing in calls. This is significant because it hits all immediate arguments to calls on x86-32. llvm-svn: 57556
* fold immediates into stores in simple cases, this produces diffs like Chris Lattner2008-10-151-30/+46
| | | | | | | | | | this: - movl $0, %eax - movl %eax, _yy_n_chars + movl $0, _yy_n_chars llvm-svn: 57555
* fold compare of null pointer into compare with 0.Chris Lattner2008-10-151-0/+4
| | | | llvm-svn: 57553
* Some minor cleanups:Chris Lattner2008-10-151-40/+30
| | | | | | | | | | | | | 1. Compute action in X86SelectSelect based on MVT instead of type. 2. Use TLI.getValueType(..) instead of MVT::getVT(..) because the former handles pointers and the later doesn't. 3. Don't pass TLI into isTypeLegal, since it already has access to it as an ivar. #2 gives fast isel some minor new functionality: handling load/stores of pointers. llvm-svn: 57552
* Use switch on VT instead of Type* comparisons.Chris Lattner2008-10-151-19/+18

* Use X86FastEmitCompare for FCMP_OEQ and FCMP_UNE: it doesn'tChris Lattner2008-10-151-17/+8
| | | | | | change the generated code, but makes the code simpler. llvm-svn: 57550
* refactor compare emission out into a new X86FastEmitCompare method,Chris Lattner2008-10-151-29/+49
| | | | | | | | which makes it easy to share the compare/imm folding logic with 'setcc'. This shaves a bunch of instructions off the common select case, which happens a lot in llvm-gcc. llvm-svn: 57549
* Fold immediates into compares when possible, producing "cmp $4, %eax" instead ofChris Lattner2008-10-151-3/+36
| | | | | | loading 4 into a register and then doing the compare. llvm-svn: 57548

* Adjust whitespace in debug messages to be more consistentDan Gohman2008-10-152-5/+5

* - Add target lowering hooks that specify which setcc conditions are illegal,Evan Cheng2008-10-153-26/+66
| | | | | | | | | | | i.e. conditions that cannot be checked with a single instruction. For example, SETONE and SETUEQ on x86. - Teach legalizer to implement *illegal* setcc as a and / or of a number of legal setcc nodes. For now, only implement FP conditions. e.g. SETONE is implemented as SETO & SETNE, SETUEQ is SETUO | SETEQ. - Move x86 target over. llvm-svn: 57542
* FastISel support for exception-handling constructs.Dan Gohman2008-10-145-57/+159
| | | | | | | | | - Move the EH landing-pad code and adjust it so that it works with FastISel as well as with SDISel. - Add FastISel support for @llvm.eh.exception and @llvm.eh.selector. llvm-svn: 57539
* Prevent assert when using '"' in names (via hexadecimal).Daniel Dunbar2008-10-141-2/+1
| | | | | | Update LangRef to mention \xx quoting in names. llvm-svn: 57538
* Change getLLVMName to use raw_ostream & PrintLLVMName.Daniel Dunbar2008-10-141-59/+15
| | | | | | | | - Avoids duplicated quotification code. - Remove QuoteNameIfNeeded. - No functionality change. llvm-svn: 57537

* Fix command-line option printing to print two spaces where needed,Dan Gohman2008-10-1425-40/+40
| | | | | | | | | instead of requiring all "short description" strings to begin with two spaces. This makes these strings less mysterious, and it fixes some cases where short description strings mistakenly did not begin with two spaces. llvm-svn: 57521

* When doing the very-late shift-and address-mode optimization,Dan Gohman2008-10-131-0/+3
| | | | | | | | | | | | | | create a new DAG node to represent the new shift to keep the DAG consistent, even though it'll almost always be folded into the address. If a user of the resulting address has multiple uses, the nodes may get revisited by a later MatchAddress call, in which case DAG inconsistencies do matter. This fixes PR2849. llvm-svn: 57465
