* Introduce a new VTSDNode class with the ultimate goal of eliminating theChris Lattner2005-07-102-79/+109
| | | | | | | | | MVTSDNode class. This class is used to provide an operand to operators that require an extra type. We start by converting FP_ROUND_INREG and SIGN_EXTEND_INREG over to using it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22364 91177308-0d34-0410-b5e6-96231b3b80d8
* Add support for emitting a .data section and .bss section.Chris Lattner2005-07-081-22/+67
| | | | | | | Add support for emitting external and .bss symbols. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22358 91177308-0d34-0410-b5e6-96231b3b80d8
* Add support for emitting the symbol table (and its string table) of theChris Lattner2005-07-071-54/+141
| | | | | | | | | | | | | | | | | | | | | module to the ELF file. Test it by adding support for emitting common symbols. This allows us to compile this: %X = weak global int 0 %Y = weak global int 0 %Z = weak global int 0 to an elf file that 'readelf's this: Symbol table '.symtab' contains 4 entries: Num: Value Size Type Bind Vis Ndx Name 0: 00000000 0 NOTYPE LOCAL DEFAULT UND 1: 00000004 4 OBJECT GLOBAL DEFAULT COM X 2: 00000004 4 OBJECT GLOBAL DEFAULT COM Y 3: 00000004 4 OBJECT GLOBAL DEFAULT COM Z git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22343 91177308-0d34-0410-b5e6-96231b3b80d8
* Make several cleanups to Andrews varargs change:Chris Lattner2005-07-051-22/+25
| | | | | | | | | | | 1. Pass Value*'s into lowering methods so that the proper pointers can be added to load/stores from the valist 2. Intrinsics that return void should only return a token chain, not a token chain/retval pair. 3. Rename LowerVAArgNext -> LowerVAArg, because VANext is long gone. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22338 91177308-0d34-0410-b5e6-96231b3b80d8
* 2 fixes:Andrew Lenharth2005-07-051-4/+13
| | | | | | | | | 1: Legalize operand in UINT_TO_FP expanision 2: SRA x, const i8 was not promoting the constant to shift amount type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22337 91177308-0d34-0410-b5e6-96231b3b80d8
* I really didn't think this was necessary. But, Legalize wasn't running againAndrew Lenharth2005-07-021-2/+3
| | | | | | | and legalizing the extload. Strange. Should fix most alpha regressions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22329 91177308-0d34-0410-b5e6-96231b3b80d8

* Adapt the code for handling uint -> fp conversion for the 32 bit case toAndrew Lenharth2005-06-271-0/+35
| | | | | | | handling it in the 64 bit case. The two code paths should probably be merged. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22302 91177308-0d34-0410-b5e6-96231b3b80d8
* iniital checkin of ELFWriter implementationChris Lattner2005-06-271-0/+230
| | | | | | | | | For now, the elf writer is only capable of emitting an empty elf file, with a section table and a section table string table. This will be enhanced in the future :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22291 91177308-0d34-0410-b5e6-96231b3b80d8
