* Emit a symbol table entry for each function we output to the ELF file. ThisChris Lattner2005-07-111-1/+31
| | | | | | | | | | | | | allows objdump to know which function we are emitting to: 00000000 <foo>: <---- 0: b8 01 00 00 00 mov $0x1,%eax 5: 03 44 24 04 add 0x4(%esp,1),%eax 9: c3 ret ... and allows .o files to be useful for linking :) llvm-svn: 22378
* add code to emit the .text section to the section header.Chris Lattner2005-07-111-4/+89
| | | | | | | | | | | | | | | | | | | | | | | | | Add a *VERY INITIAL* machine code emitter class. This is enough to take this C function: int foo(int X) { return X +1; } and make objdump produce the following: $ objdump -d t-llvm.o t-llvm.o: file format elf32-i386 Disassembly of section .text: 00000000 <.text>: 0: b8 01 00 00 00 mov $0x1,%eax 5: 03 44 24 04 add 0x4(%esp,1),%eax 9: c3 ret Anything using branches or refering to the constant pool or requiring relocations will not work yet. llvm-svn: 22375

* Add support for emitting a .data section and .bss section.Chris Lattner2005-07-081-22/+67

* 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 llvm-svn: 22343
* 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 :) llvm-svn: 22291
