* Stop building RTTI information for *most* llvm libraries. NotableChris Lattner2010-01-22
| | | | | | | | | | | | | 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
* Now that we have everything nicely factored (e.g. asmprinter is notChris Lattner2010-01-19
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Add a new virtual EmitStartOfAsmFile method to the AsmPrinter and use thisBob Wilson2009-09-30
| | | | | | | | | | | | | | | | | to emit target-specific things at the beginning of the asm output. This fixes a problem for PPC, where the text sections are not being kept together as expected. The base class doInitialization code calls DW->BeginModule() which emits a bunch of DWARF section directives. The PPC doInitialization code then emits all the TEXT section directives, with the intention that they will be kept together. But as I understand it, the Darwin assembler treats the default TEXT section as a special case and moves it to the beginning of the file, which means that all those DWARF sections are in the middle of the text. With this change, the EmitStartOfAsmFile hook is called before the DWARF section directives are emitted, so that all the PPC text section directives come out right at the beginning of the file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83176 91177308-0d34-0410-b5e6-96231b3b80d8

* remove DebugLoc from MCInst and eliminate "Comment printing" fromChris Lattner2009-09-09
| | | | | | | | | | | | | | | the MCInst path of the asmprinter. Instead, pull comment printing out of the autogenerated asmprinter into each target that uses the autogenerated asmprinter. This causes code duplication into each target, but in a way that will be easier to clean up later when more asmprinter stuff is commonized into the base AsmPrinter class. This also fixes an xcore strangeness where it inserted two tabs before every instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81396 91177308-0d34-0410-b5e6-96231b3b80d8

* Rip all of the global variable lowering logic out of TargetAsmInfo. SinceChris Lattner2009-07-28
| | | | | | | | | | | | | | | | | | | | | | | it is highly specific to the object file that will be generated in the end, this introduces a new TargetLoweringObjectFile interface that is implemented for each of ELF/MachO/COFF/Alpha/PIC16 and XCore. Though still is still a brutal and ugly refactoring, this is a major step towards goodness. This patch also: 1. fixes a bunch of dangling pointer problems in the PIC16 backend. 2. disables the TargetLowering copy ctor which PIC16 was accidentally using. 3. gets us closer to xcore having its own crazy target section flags and pic16 not having to shadow sections with its own objects. 4. fixes wierdness where ELF targets would set CStringSection but not CStringSection_. Factor the code better. 5. fixes some bugs in string lowering on ELF targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77294 91177308-0d34-0410-b5e6-96231b3b80d8

* Reapply my previous asmprinter changes now with more testing and two Chris Lattner2009-07-14
| | | | | | | | | | | | | | | | | | | | | | additional bug fixes: 1. The bug that everyone hit was a problem in the asmprinter where it would remove $stub but keep the L prefix on a name when emitting the indirect symbol. This is easy to fix by keeping the name of the stub and the name of the symbol in a StringMap instead of just keeping a StringSet and trying to reconstruct it late. 2. There was a problem printing the personality function. The current logic to print out the personality function from the DWARF information is a bit of a cesspool right now that duplicates a bunch of other logic in the asm printer. The short version of it is that it depends on emitting both the L and _ prefix for symbols (at least on darwin) and until I can untangle it, it is best to switch the mangler back to emitting both prefixes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75646 91177308-0d34-0410-b5e6-96231b3b80d8
