* Rip all of the global variable lowering logic out of TargetAsmInfo. SinceChris Lattner2009-07-283-14/+9
| | | | | | | | | | | | | | | | | | | | | | | 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

* Simplify JIT target selection.Daniel Dunbar2009-07-251-12/+2
| | | | | | | | | | | - Instead of requiring targets to define a JIT quality match function, we just have them specify if they support a JIT. - Target selection for the JIT just gets the host triple and looks for the best target which matches the triple and has a JIT. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77060 91177308-0d34-0410-b5e6-96231b3b80d8

* More migration to raw_ostream, the water has dried up around the iostream hole.Daniel Dunbar2009-07-251-1/+2
| | | | | | | | | | | - Some clients which used DOUT have moved to DEBUG. We are deprecating the "magic" DOUT behavior which avoided calling printing functions when the statement was disabled. In addition to being unnecessary magic, it had the downside of leaving code in -Asserts builds, and of hiding potentially unnecessary computations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77019 91177308-0d34-0410-b5e6-96231b3b80d8

* Reapply my previous asmprinter changes now with more testing and two Chris Lattner2009-07-141-5/+2
| | | | | | | | | | | | | | | | | | | | | | 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
