lower the SETB* instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95431 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-04Rewrite FP constant handling in DEBUG_VALUE yetDale Johannesen
again, so it more or less handles long double. Restore \n removed in latest MC frenzy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95271 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-03make the x86 backend emit darwin stubs through mcstreamerChris Lattner
instead of textually. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95206 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-03make MachineModuleInfoMachO hold non-const MCSymbol*'s insteadChris Lattner
of const ones. non-const ones aren't very useful, because you can't even, say, emit them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95205 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-03don't emit \n's at the start of X86AsmPrinter::runOnMachineFunction,Chris Lattner
.o files don't like that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95187 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-03Finally eliminate printMCInst and send instructions throughChris Lattner

2010-02-03rejigger the world so that EmitInstruction prints the \n atChris Lattner
the end of the instruction instead of expecting the caller to do it. This currently causes the asm-verbose instruction comments to be on the next line. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95178 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-03sink handling of target-independent machine instrs (otherChris Lattner
than DEBUG_VALUE :( ) into the target indep AsmPrinter.cpp file. This allows elimination of the NO_ASM_WRITER_BOILERPLATE hack among other things. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95177 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-03Print FPImm a less kludgy way; APFloat.toString seemsDale Johannesen
to have some problems anyway. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95171 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-02refactor code so that LLVMTargetMachine creates the asmstreamer and Chris Lattner
mccontext instead of having AsmPrinter do it. This allows other types of MCStreamer's to be passed in. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95155 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-28Remove the argument from EmitJumpTableInfo, because it doesn't need it.Chris Lattner
Move the X86 implementation of function body emission up to AsmPrinter::EmitFunctionBody, which works by calling the virtual EmitInstruction method. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94716 91177308-0d34-0410-b5e6-96231b3b80d8

per document. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94693 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-26now that enough stuff is constified, move function header printingChris Lattner
logic up from X86 into the common code. The other targets will hopefully start using this soon. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94614 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-26Move getJTISymbol from MachineJumpTableInfo to MachineFunction,Chris Lattner
which is more convenient, and change getPICJumpTableRelocBaseExpr to take a MachineFunction to match. Next, move the X86 code that create a PICBase symbol to X86TargetLowering::getPICBaseSymbol from X86MCInstLower::GetPICBaseSymbol, which was an asmprinter specific library. This eliminates a 'gross hack', and allows us to implement X86ISelLowering::getPICJumpTableRelocBaseExpr which now calls it. This in turn allows us to eliminate the X86AsmPrinter::printPICJumpTableSetLabel method, which was the only overload of printPICJumpTableSetLabel. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94526 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-26simplify asmprinter: only emit .set directives when entries haveChris Lattner
EK_LabelDifference32 kind and the target has .set support. Simplify X86AsmPrinter::printPICJumpTableSetLabel to make use of recent helpers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94518 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-26implement X86 @GOTOFF jump table entries with the new EK_Custom32Chris Lattner
jump table entry kind, instead of overloading AsmPrinter::printPICJumpTableEntry. This has a pretty horrible and inefficient FIXME around how @GOTOFF is currently smashed into the mcsymbol name, but otherwise this is much cleaner. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94516 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-26add a new MachineBasicBlock::getSymbol method, replacingChris Lattner
the AsmPrinter::GetMBBSymbol. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94515 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-26don't bother setting the AsmPrinter::MF ivar, now thatChris Lattner
AsmPrinter::SetupMachineFunction sets it. Note that systemz and msp430 didn't. Yay for reduced inconsistency! :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94510 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-26Accept immediate as value of a dbg_value.Dale Johannesen
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94489 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-25Rearrange handling of jump tables. Highlights:Chris Lattner
1. MachineJumpTableInfo is now created lazily for a function the first time it actually makes a jump table instead of for every function. 2. The encoding of jump table entries is now described by the MachineJumpTableInfo::JTEntryKind enum. This enum is determined by the TLI::getJumpTableEncoding() hook, instead of by lots of code scattered throughout the compiler that "knows" that jump table entries are always 32-bits in pic mode (for example). 3. The size and alignment of jump table entries is now calculated based on their kind, instead of at machinefunction creation time. Future work includes using the EntryKind in more places in the compiler, eliminating other logic that "knows" the layout of jump tables in various situations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94470 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-25eliminate redundant argument to EmitJumpTableInfoChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94464 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-25handle the _set_ symbol with an MCSymbol.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94449 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-25pull the non-pic jump table case out of printPICJumpTableEntryChris Lattner
and MCize the non-pic case. Now printPICJumpTableEntry really is just about printing PIC entries. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94446 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-25remove JumpTableDirective, it is always null.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94445 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-25sink an arm specific method out of asmprinter into the ARMAsmPrinter andChris Lattner
rename it to avoid shadowing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94440 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-25mcstreamerize .file and .file. This also fixes an issue where theChris Lattner
normal form of .file would fail if the filename had a weird character in it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94437 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-25emit ELF .type directives through MCStreamer instead of doing it textually.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94436 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94378 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-23move the various directive enums out of the MCStreamer classChris Lattner
into a new MCDirectives.h file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94294 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-23use some helpers instead of duplicating logic.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94285 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-22Stop building RTTI information for *most* llvm libraries. NotableChris Lattner
missing ones are libsupport, libsystem and libvmcore. libvmcore is currently blocked on bugpoint, which uses EH. Once it stops using EH, we can switch it off. This #if 0's out 3 unit tests, because gtest requires RTTI information. Suggestions welcome on how to fix this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94164 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-19Avoid including DebugInfo.h in AsmPrinter.hDevang Patel
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93864 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-19Now that we have everything nicely factored (e.g. asmprinter is notChris Lattner
doing global variable classification anymore) and hookized, sink almost all target targets global variable emission code into AsmPrinter and out of each target. Some notes: 1. PIC16 does completely custom and crazy stuff, so it is not changed. 2. XCore has some custom handling for extra directives. I'll look at it next. 3. This switches linux/ppc to use .globl instead of .global. If .globl is actually wrong, let me know and I'll fix it. 4. This makes linux/ppc get a lot of random cases right which were obviously wrong before, it is probably now a bit healthier. 5. Blackfin will probably start getting .comm and other things that it didn't before. If this is undesirable, it should explicitly opt out of these things by clearing the relevant fields of MCAsmInfo. This leads to a nice diffstat: 14 files changed, 127 insertions(+), 830 deletions(-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93858 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-19hookize the cygwin ".linkonce" directive.Chris Lattner

2010-01-19more cleanups. Emit the .local directive even on cygwin/mingw.Chris Lattner
I'm not sure that this is correct, but it causes no test failures, and just emitting a .comm without protecting its linkage somehow is surely not right. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93854 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-19add a bool for whether .lcomm takes an alignment instead of basing this on ↵Chris Lattner
"isdarwin". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93852 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-19hoist handling of external globals and special globals up to common code.Chris Lattner
This makes a similar code dead in all the other targets, I'll clean it up in a bit. This also moves handling of lcomm up before acquisition of a section, since lcomm never needs a section. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93851 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-19use BSSLocal classifier to identify 'lcomm' data instead ofChris Lattner
duplicating the logic (differently) in lots of different targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93847 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-19now that elf weak bss symbols are handled correctly, simplify a bunch of code.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93845 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-19fix a significant difference between llvm and gcc on ELF systems:Chris Lattner
GCC would put weak zero initialized mutable data in the .bss section, we would put it into a crasy '.gnu.linkonce.b.test,"aw",@nobits' section. Fixing this will allow simplifications next up. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93844 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-19introduce a section kind for common linkage. Use this to slightlyChris Lattner
simplify and commonize some of the asmprinter logic for globals. This also avoids printing the MCSection for .zerofill, which broke the llvm-gcc build. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93843 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-19Cleanup handling of .zerofill on darwin:Chris Lattner
1. TargetLoweringObjectFileMachO should decide if something goes in zerofill instead of having every target do it. 2. TargetLoweringObjectFileMachO should assign said symbols to the right MCSection, the asmprinters should just emit to the right section. 3. Since all zerofill stuff goes through mcstreamer anymore, MAI can have a bool "haszerofill" instead of having the textual directive to emit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93838 91177308-0d34-0410-b5e6-96231b3b80d8
