2011-07-20Goodbye TargetAsmInfo. This eliminate last bit of CodeGen and Target in llvm-mc.Evan Cheng
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135611 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-18Eliminate TargetAsmInfo::getCompactUnwindEncoding. This get rid of theEvan Cheng
use of TargetFrameLowering in TargetAsmInfo. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135439 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-18Move getInitialFrameState from TargetFrameInfo to MCAsmInfo (suggestions forEvan Cheng
better location welcome). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135438 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-18Sink getDwarfRegNum, getLLVMRegNum, getSEHRegNum from TargetRegisterInfo downEvan Cheng
to MCRegisterInfo. Also initialize the mapping at construction time. This patch eliminate TargetRegisterInfo from TargetAsmInfo. It's another step towards fixing the layering violation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135424 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-15Move some parts of TargetAsmInfo down to MCAsmInfo. This is not the greatestEvan Cheng
solution but it is a small step towards removing the horror that is TargetAsmInfo. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135237 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-12There is a cyclic dependency between MC and Target if this method is ↵Bill Wendling
out-of-line. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135006 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-07Add a target hook to encode the compact unwind information.Bill Wendling
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134577 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-10Rename TargetFrameInfo into TargetFrameLowering. Also, put couple of FIXMEs ↵Anton Korobeynikov
and fixes here and there. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123170 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-09Initial support for the cfi directives. This is just enough to getRafael Espindola
f: .cfi_startproc nop .cfi_endproc assembled (on ELF). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121434 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-22move the MCAsmInfo .cpp/.h files into the right Chris Lattner
directories and rename them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79768 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-22Rename TargetAsmInfo (and its subclasses) to MCAsmInfo.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79763 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-13Remove HasCrazyBSS and add a flag in TAI to indicate that '.section' Bruno Cardoso Lopes
must be emitted for PowerPC-Linux '.bss' section git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78958 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-11Change the asmprinter to print the comment character before theChris Lattner
"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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78737 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-11split "JumpTableDirective" (an existing hack) into a PIC and nonPICChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78709 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-11SjLj based exception handling unwinding support. This patch is nasty, brutishJim Grosbach
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78625 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-081. Make MCSection an abstract class.Chris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78510 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-08eliminate TargetLoweringObjectFileSparc in favor of a TAI hook.Chris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78498 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-07remove a bunch of now-dead crud from the asmprinter and TAI interfaces.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78428 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-05remove the 'DataSectionStartSuffix' and 'TextSectionStartSuffix' knobs.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78242 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-04rip out SectionEndDirectiveSuffix support, only uses byChris Lattner
the masm backend. If anyone cares about masm in the future, we'll have semantic sections it can hang off of. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78096 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-02move dwarf debug info section selection stuff from TAI toChris Lattner
TLOF, unifying all the dwarf targets at the same time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77889 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-02convert EHFrameSection to be managed by TLOF instead of TAI.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77888 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-02Move the getInlineAsmLength virtual method from TAI to TII, whereChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77877 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-02remove TargetAsmInfo::TM, which is now dead. The basic TAI class now Chris Lattner
no longer depends on TM! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77863 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77858 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-02remove the dead PreferredEHDataFormat TAI hook: its now deadChris Lattner
even considering #if 0 code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77856 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-02move getDwarfExceptionSection from TAI to TLOF and rename it to Chris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77847 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-02convert ctors/dtors section to be in TLOF instead ofChris Lattner
TAI. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77842 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-01Remove "JumpTableDataSection" from TAI, instead, have AsmPrinterChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77833 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-31PreferredEHDataFormat is always call with data and global, but this wholeChris Lattner
thing is #if0'd out anyway. Just simplify the code by reducing the interface. Not deleting this is essential for Bill's continuing happiness. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77736 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-28Rip all of the global variable lowering logic out of TargetAsmInfo. SinceChris Lattner
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
2009-07-27Sink getSectionPrefixForUniqueGlobal down into the TAI Chris Lattner

2009-07-26untangle a TargetAsmInfo hack where ELFTargetAsmInfo would create aChris Lattner
'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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77165 91177308-0d34-0410-b5e6-96231b3b80d8
