2010-10-11Per discussion with Sanjiv, remove the PIC16 target from mainline. When/ifChris Lattner
it comes back, it will be largely a rewrite, so keeping the old codebase in tree isn't helping anyone. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116190 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-17Add const qualifiers to TargetLoweringObjectFile usage.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101640 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-17Use const qualifiers with TargetLowering. This eliminates severalDan Gohman
const_casts, and it reinforces the design of the Target classes being immutable. SelectionDAGISel::IsLegalToFold is now a static member function, because PIC16 uses it in an unconventional way. There is more room for API cleanup here. And PIC16's AsmPrinter no longer uses TargetLowering. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101635 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-16The code section for an ISR has a specific address.Sanjiv Gupta
Currently, whether a function is ISR or not is encoded in the section attribute for that function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96322 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-21Add a pass to overlay pic16 data sections for function frame and automaticSanjiv Gupta
variables. This pass can be invoked by llvm-ld or opt to traverse over the call graph to detect what function frames and their automatic variables can be overlaid. Currently this builds an archive , but needs to be changed to a loadable module. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84753 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-20Implement support for ISRs. Sanjiv Gupta
Clone functions that are shared between the Main thread and Interrupt thread. CallSites are changed in AsmPrinter currently. A better solution would have been to modify the legalizer (SoftenFloat) to allow targets to change the name of libcalls for float operations. But that currently breaks other targets. Also, cloing of automatic variables is done AsmPrinter, a better approach would be to use the ValueMap in CloneFunction itself. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79562 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-08sink the 'name' and 'isdirective' state out of MCSection into its derived ↵Chris Lattner

2009-08-06Fix several fixmes and clean up code by sinking *all* sectionChris Lattner
creation activity into the target-specific subclasses of TLOF. Before this, globals with explicit sections could be created by the base class. 1. make getOrCreateSection protected, add a new getExplicitSectionGlobal pure virtual method to assign sections to globals with a specified section. 2. eliminate getSpecialCasedSectionGlobals, which is now PIC specific. 3. eliminate the getKindForNamedSection virtual method, which is now just a static method for ELF. 4. Add implementions of getExplicitSectionGlobal for ELF/PECOFF/Darwin/PIC16. They are now all detangled and understandable, woo! :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78319 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-01it turns out that isWeak() was basically dead anyway. Kill off SectionInfo :-/Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77812 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-01Change SectionKind to be a property that is true of a *section*, itChris Lattner
should have no state that is specific to particular globals in the section. In this case, it means the removal of the "isWeak" and "ExplicitSection" bits. MCSection uses the new form of SectionKind. To handle isWeak, I introduced a new SectionInfo class, which is SectionKind + isWeak, and it is used by the part of the code generator that does classification of a specific global. The ExplicitSection disappears. It is moved onto MCSection as a new "IsDirective" bit. Since the Name of a section is either a section or directive, it makes sense to keep this bit in MCSection. Ultimately the creator of MCSection should canonicalize (e.g.) .text to whatever the actual section is. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77803 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-31switch off of 'Section' onto MCSection. We're not properly usingChris Lattner
MCSection subclasses yet, but this is a step in the right direction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77708 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
