2009-04-29Instead of passing in an unsigned value for the optimization level, use an enum,Bill Wendling
which better identifies what the optimization is doing. And is more flexible for future uses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70440 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-29Second attempt:Bill Wendling
Massive check in. This changes the "-fast" flag to "-O#" in llc. If you want to use the old behavior, the flag is -O0. This change allows for finer-grained control over which optimizations are run at different -O levels. Most of this work was pretty mechanical. The majority of the fixes came from verifying that a "fast" variable wasn't used anymore. The JIT still uses a "Fast" flag. I'll change the JIT with a follow-up patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70343 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-13Fix escaping in asm string literals correctly by having tblgen unescape Chris Lattner
them, then the asmprinter emitter reescape them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66958 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-24Overhaul my earlier submission due to feedback. It's a large patch, but most ofBill Wendling
them are generic changes. - Use the "fast" flag that's already being passed into the asm printers instead of shoving it into the DwarfWriter. - Instead of calling "MI->getParent()->getParent()" for every MI, set the machine function when calling "runOnMachineFunction" in the asm printers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65379 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-24- Use the "Fast" flag instead of "OptimizeForSize" to determine whether to emitBill Wendling
a DBG_LABEL or not. We want to fall back to the original way of emitting debug info when we're in -O0/-fast mode. - Add plumbing in to pass the "Fast" flag to places that need it. - XFAIL DebugInfo/deaddebuglabel.ll. This is finding 11 labels instead of 8. I need to investigate still. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65367 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-20We have logic in there to emit a default debugging label at the beginning of aBill Wendling
function. Emitting another label after the prologue messes up the debugging. We are doing that because the first DebugLoc object it sees is different from the previous, which was nothing. Check for this situation, and don't emit one if it's the first. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65180 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-19Print out a new label only if the debug location *tuple* is different. The debugBill Wendling
locations may change, but the tuples may be the same. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65039 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-19Forgot to check that debug information is supported.Bill Wendling

2009-02-18Put code that generates debug labels into TableGen so that it can be used byBill Wendling
everyone. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64978 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-26Add a default constructor to AsmWriterOperand to make VS2008sp1 happy. ↵Cedric Venet
(AsmWriterOperand is used in a std::pair, and VS need to generate the default constructor of this pair). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58185 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-01Split ISD::LABEL into ISD::DBG_LABEL and ISD::EH_LABEL, eliminatingDan Gohman
the need for a flavor operand, and add a new SDNode subclass, LabelSDNode, for use with them to eliminate the need for a label id operand. Change instruction selection to let these label nodes through unmodified instead of creating copies of them. Teach the MachineInstr emitter how to emit a MachineInstr directly from an ISD label node. This avoids the need for allocating SDNodes for the label id and flavor value, as well as SDNodes for each of the post-isel label, label id, and label flavor. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52943 91177308-0d34-0410-b5e6-96231b3b80d8
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
2008-03-17Add support for escaping {} in asm strings, based on patch from Nick Burns.Nate Begeman

2008-02-02Get rid of the annoying blank lines before labels.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46667 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-02SDIsel processes llvm.dbg.declare by recording the variable debug ↵Evan Cheng
information descriptor and its corresponding stack frame index in MachineModuleInfo. This only works if the local variable is "homed" in the stack frame. It does not work for byval parameter, etc. Added ISD::DECLARE node type to represent llvm.dbg.declare intrinsic. Now the intrinsic calls are lowered into a SDNode and lives on through out the codegen passes. For now, since all the debugging information recording is done at isel time, when a ISD::DECLARE node is selected, it has the side effect of also recording the variable. This is a short term solution that should be fixed in time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46659 91177308-0d34-0410-b5e6-96231b3b80d8

2006-11-15Remove the isTwoAddress property from the CodeGenInstruction class. It shouldChris Lattner
not be used for anything other than backwards compat constraint handling. Add support for a new DisableEncoding property which contains a list of registers that should not be encoded by the generated code emitter. Convert the codeemitter generator to use this, fixing some PPC JIT regressions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31769 91177308-0d34-0410-b5e6-96231b3b80d8

2006-09-27This:Chris Lattner
AggregateString += "\0\0"; Doesn't add two nuls to the AggregateString (for obvious reasons), which broke the asmprinter when the first character of an asm string was not literal text. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30625 91177308-0d34-0410-b5e6-96231b3b80d8

2006-09-26Add support for ${:foo} syntax, where "foo" is passed into "printSpecial" andChris Lattner
has no associated operand. This is useful for portably encoding stuff like the comment character into an asm string. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30617 91177308-0d34-0410-b5e6-96231b3b80d8
2006-09-05Fix a long-standing wart in the code generator: two-address instruction loweringChris Lattner
actually *removes* one of the operands, instead of just assigning both operands the same register. This make reasoning about instructions unnecessarily complex, because you need to know if you are before or after register allocation to match up operand #'s with the target description file. Changing this also gets rid of a bunch of hacky code in various places. This patch also includes changes to fold loads into cmp/test instructions in the X86 backend, along with a significant simplification to the X86 spill folding code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30108 91177308-0d34-0410-b5e6-96231b3b80d8
2006-07-19Fix a bug handling instructions, like blr, which just consist of a textChris Lattner
string. The return value of printInstruction should be true for these. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29196 91177308-0d34-0410-b5e6-96231b3b80d8
2006-07-18Fix case where identical cases were not detected across case #0, becauseChris Lattner
instructions not handled would have a case value of #0, throwing things off. This marginally shrinks the X86 asmprinter, but shrinks the sparc asmwriter by 25 lines. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29187 91177308-0d34-0410-b5e6-96231b3b80d8
2006-07-18Fix an accidentally duplicated line that caused tblgen to crash on itanium.Chris Lattner
Add an assert that catches the real problem earlier. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29185 91177308-0d34-0410-b5e6-96231b3b80d8
2006-07-18Maximally group commands. When all instructions within a command set have aChris Lattner
series of identical commands, handle them all with one switch. In the case of the x86 at&t asm printer, only 3 switches are needed for all instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29184 91177308-0d34-0410-b5e6-96231b3b80d8

2006-07-18Handle the last operand more intelligently. When emitting the \n, alsoChris Lattner
return from the asmprinter to make the generated asmprinter both more efficient and smaller. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29182 91177308-0d34-0410-b5e6-96231b3b80d8

2006-07-18Steal bits from the asm string index to use for operand information. On bothChris Lattner
x86 and ppc, this gets us 4 more bits to play with, since the string indices both only use 12 bits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29180 91177308-0d34-0410-b5e6-96231b3b80d8

2006-07-18Completely change the structure of the generated asmprinter to be more tableChris Lattner
based and less switch-statements-with-hundreds-of-cases based. This shrinks the x86 asmprinters to about 1/3 their previous size. Other improvements coming. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29177 91177308-0d34-0410-b5e6-96231b3b80d8

2006-07-14Emit the string information for the asm writer as a single large stringChris Lattner
and index into it, instead of emitting it like this: static const char * const OpStrs[] = { "PHINODE\n", // PHI 0, // INLINEASM "adc ", // ADC32mi "adc ", // ADC32mi8 ... The old way required thousands of relocations that slows down link time and dynamic load times. This also cuts about 10K off each of the X86 asmprinters, and should shrink the others as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29152 91177308-0d34-0410-b5e6-96231b3b80d8
