* Goodbye TargetAsmInfo. This eliminate last bit of CodeGen and Target in llvm-mc.Evan Cheng2011-07-201-18/+0
| | | | | | | There is still a bit more refactoring left to do in Targets. But we are now very close to fixing all the layering issues in MC. llvm-svn: 135611

* Sink getDwarfRegNum, getLLVMRegNum, getSEHRegNum from TargetRegisterInfo downEvan Cheng2011-07-181-1/+0

* Rename TargetAsmInfo (and its subclasses) to MCAsmInfo.Chris Lattner2009-08-221-6/+6

* Change the asmprinter to print the comment character before theChris Lattner2009-08-111-2/+2
| | | | | | | | | | "inlineasmstart/end" strings so that the contents of the directive are separate from the comment character. This lets elf targets get #APP/#NOAPP for free even if they don't use "#" as the comment character. This also allows hoisting the darwin stuff up to the shared TAI class. llvm-svn: 78737
* split "JumpTableDirective" (an existing hack) into a PIC and nonPICChris Lattner2009-08-111-0/+1
| | | | | | | | | | version. This allows TAI implementations to specify the directive to use based on the mode being codegen'd for. The real fix for this is to remove JumpTableDirective, but I don't feel like diving into the jumptable snarl just now. llvm-svn: 78709
* SjLj based exception handling unwinding support. This patch is nasty, brutishJim Grosbach2009-08-111-1/+1
| | | | | | | | | | | | | and short. Well, it's kinda short. Definitely nasty and brutish. The front-end generates the register/unregister calls into the SjLj runtime, call-site indices and landing pad dispatch. The back end fills in the LSDA with the call-site information provided by the front end. Catch blocks are not yet implemented. Built on Darwin and verified no llvm-core "make check" regressions. llvm-svn: 78625
* 1. Make MCSection an abstract class.Chris Lattner2009-08-081-1/+0
| | | | | | | | | 2. Move section switch printing to MCSection virtual method which takes a TAI. This eliminates textual formatting stuff from TLOF. 3. Eliminate SwitchToSectionDirective, getSectionFlagsAsString, and TLOFELF::AtIsCommentChar. llvm-svn: 78510
* eliminate TargetLoweringObjectFileSparc in favor of a TAI hook.Chris Lattner2009-08-081-0/+1
| | | | | | | | A TAI hook is appropriate in this case because this is just an asm syntax issue, not a semantic difference. TLOF should model the semantics of the section. llvm-svn: 78498
* remove a bunch of now-dead crud from the asmprinter and TAI interfaces.Chris Lattner2009-08-071-2/+0

* remove the 'DataSectionStartSuffix' and 'TextSectionStartSuffix' knobs.Chris Lattner2009-08-051-2/+0

* rip out SectionEndDirectiveSuffix support, only uses byChris Lattner2009-08-041-1/+0
| | | | | | | the masm backend. If anyone cares about masm in the future, we'll have semantic sections it can hang off of. llvm-svn: 78096
* move dwarf debug info section selection stuff from TAI toChris Lattner2009-08-021-12/+1
| | | | | | TLOF, unifying all the dwarf targets at the same time. llvm-svn: 77889
* convert EHFrameSection to be managed by TLOF instead of TAI.Chris Lattner2009-08-021-1/+0

* Move the getInlineAsmLength virtual method from TAI to TII, whereChris Lattner2009-08-021-25/+0
| | | | | | | | | | the only real caller (GetFunctionSizeInBytes) uses it. The custom ARM implementation of this is basically reimplementing an assembler poorly for negligible gain. It should be removed IMNSHO, but I'll leave that to ARMish folks to decide. llvm-svn: 77877
* remove TargetAsmInfo::TM, which is now dead. The basic TAI class now Chris Lattner2009-08-021-1/+1
| | | | | | no longer depends on TM! llvm-svn: 77863
* clean up #includes of TargetAsmInfo.cppChris Lattner2009-08-021-11/+0

* remove the dead PreferredEHDataFormat TAI hook: its now deadChris Lattner2009-08-021-4/+0
| | | | | | even considering #if 0 code. llvm-svn: 77856
* move getDwarfExceptionSection from TAI to TLOF and rename it to Chris Lattner2009-08-021-1/+0
| | | | | | | | | | | getLSDASection() to be more specific. This makes it pretty obvious that the ELF LSDA section is being specified wrong in PIC mode. We're probably getting a lot of startup-time relocations to a readonly page, which is expensive and bad. Someone who cares about ELF C++ should investigate this. llvm-svn: 77847

* Remove "JumpTableDataSection" from TAI, instead, have AsmPrinterChris Lattner2009-08-011-1/+0
| | | | | | | | | | | | compute it based on what it knows. As part of this, rename getSectionForMergeableConstant to getSectionForConstant because it works for non-mergable constants also. The only functionality change from this is that Xcore will start dropping its jump tables into readonly section instead of data section in -static mode. This should be fine as the linker resolves the relocations. If this is a problem, let me know and we'll come up with another solution. llvm-svn: 77833

* PreferredEHDataFormat is always call with data and global, but this wholeChris Lattner2009-07-311-2/+1
| | | | | | | thing is #if0'd out anyway. Just simplify the code by reducing the interface. Not deleting this is essential for Bill's continuing happiness. llvm-svn: 77736
* Rip all of the global variable lowering logic out of TargetAsmInfo. SinceChris Lattner2009-07-281-218/+0
| | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 77294

* untangle a TargetAsmInfo hack where ELFTargetAsmInfo would create aChris Lattner2009-07-261-6/+5
| | | | | | | | | 'unnamed' bss section, but some impls would want a named one. Since they don't have consistent behavior, just make each target do their own thing, instead of doing something "sortof common" then having targets change immutable objects later. llvm-svn: 77165
