2009-08-13fix a minor fixme. When building with SL and later tools, the ".eh" symbolsChris Lattner
don't need to be exported from the .o files. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78892 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-12Change TargetAsmInfo to be constructed via TargetRegistry from a Target+TripleChris Lattner
pair instead of from a virtual method on TargetMachine. This cuts the final ties of TargetAsmInfo to TargetMachine, meaning that MC can now use TargetAsmInfo. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78802 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-11change the -x86-asm-syntax=intel/att flag to be in X86TAI Chris Lattner
instead of X86 Subtarget. This elimianates dependencies on X86Subtarget from X86TAI. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78746 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

2009-08-11SjLj 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

2009-08-04rip 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
2009-08-02remove 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@77861 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
2009-08-01Remove "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
2009-07-27make COFF work like ELF and macho, by splitting out into its ownChris Lattner
header even though there is only one COFF target. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77204 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-27Eliminate SectionFlags, just embed a SectionKind into SectionChris Lattner
instead and drive things based off of that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77184 91177308-0d34-0410-b5e6-96231b3b80d8
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
2009-07-26remove a densemap from TargetAsmInfo that was uniquing the targetflags strings,Chris Lattner
just use a smallstring instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77144 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77138 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-26Rearrange all the SectionKinds and structure them into a hierarchicalChris Lattner
group instead of a bunch of random unrelated ideas. Provide predicates to categorize a SectionKind into a group, and use them instead of getKind() throughout the code. This also renames a ton of SectionKinds to be more consistent and evocative, and adds a huge number of comments on the enums so that I will hopefully be able to remember how this stuff works long from now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77129 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-25make SectionKind be a first-class pod struct instead of justChris Lattner
an enum. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77096 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-25this is (unfortunately) several changes mixed together:Chris Lattner
1. Spell SectionFlags::Writeable as "Writable". 2. Add predicates for deriving SectionFlags from SectionKinds. 3. Sink ELF-specific getSectionPrefixForUniqueGlobal impl into ELFTargetAsmInfo. 4. Fix SectionFlagsForGlobal to know that BSS/ThreadBSS has the BSS bit set (the real fix for PR4619). 5. Fix isSuitableForBSS to not put globals with explicit sections set in BSS (which was the reason #4 wasn't fixed earlier). 6. Remove my previous hack for PR4619. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77085 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-24make SectionKindForGlobal target independent, and therefore non-virtual.Chris Lattner
It's classifications now include elf-specific discriminators. Targets that don't have these features (like darwin and pecoff) simply treat data.rel like data, etc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76993 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-24Replace UniqueSectionForGlobal with getSectionPrefixForUniqueGlobal.Chris Lattner
The later doesn't depend on any crazy LLVM IR stuff, and this pulls the concatenation of prefix with GV name (the root problem behind PR4584) out one level. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76948 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-17Untangle a snarl that I discovered when updating the mangler,Chris Lattner
starting in getCurrentFunctionEHName. Among other problems, we would try to privative a "foo.eh" label, but end up emitting the label as _Lfoo.eh instead of L_foo.eh on darwin. This is really bad, and the linker has always tolerated these labels existing. For now, just emit them as _foo.eh. This patch also fixes problems with ".eh" labels on unnamed functions and eliminates two strangely defined TargetAsmInfo hooks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76231 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-14llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.Torok Edwin
This adds location info for all llvm_unreachable calls (which is a macro now) in !NDEBUG builds. In NDEBUG builds location info and the message is off (it only prints "UREACHABLE executed"). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75640 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-11assert(0) -> LLVM_UNREACHABLE.Torok Edwin
Make llvm_unreachable take an optional string, thus moving the cerr<< out of line. LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for NDEBUG builds. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75379 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-19merge the common darwin settings from the X86/PPC/ARM targetsChris Lattner
