Chris Lattner 51d5b43cda refactor section construction in TLOF to be through an explicit 
initialize method, which can be called when an MCContext is available.

Chris Lattner 149465ea06 Eliminate SectionFlags, just embed a SectionKind into Section 
instead and drive things based off of that.

 2009-07-27 05:32:16 +00:00
Bruno Cardoso Lopes 12e543228d Support adding relocations for data sections, handling the cases where 
global declared symbols are initialized with references from other global
symbols.

llvm-svn: 76540
 2009-07-21 06:51:32 +00:00
Bruno Cardoso Lopes 447b7fd4bb For PC relative relocations where symbols are defined in the same section they 
are referenced, ignore the relocation entry and patch the relocatable field with
the computed symbol offset directly

Bruno Cardoso Lopes 50bf9a60e5 Use R_X86_64_32S to handle Jump Table Index relocation entries. Hide TAI usage inside getSection* functions

 2009-07-18 23:24:01 +00:00
Bruno Cardoso Lopes 484e90b45e Add support to properly reference private symbols on relocation entries. 
Use proper relocation type to build relocations for JumpTables (rodata
sections).

 2009-07-16 06:26:41 +00:00
Bruno Cardoso Lopes 2717863900 use std::vector instead of std::list for both Section and Symbol lists because 
we care more about random access than insertion/deletion of elements.

Add section symbols to the symbol table

llvm-svn: 74170
 2009-06-25 07:36:24 +00:00
Bruno Cardoso Lopes 02a9191b71 Use a default alignment for data and bss sections. 
Only pad when the section size > 0 and move the code that deals
with globals initializers to a place we know for sure the global
is initialized.

llvm-svn: 73944
 2009-06-23 04:39:27 +00:00
Bruno Cardoso Lopes bd9c94d7af Use different functions to emit the string and symbol tables. 
llvm-svn: 73895
 2009-06-22 19:29:56 +00:00
Bruno Cardoso Lopes a040566fec Add more methods to gather target specific elf stuff

Use a map to track global values to their symbol table indexes

Some small fixes

llvm-svn: 73201
 2009-06-11 19:16:03 +00:00
Bruno Cardoso Lopes e577492a17 Simple ELF32/64 binary files can now be emitted for x86 and x86_64 without 
relocation sections.

llvm-svn: 73038
 2009-06-07 21:22:38 +00:00
Bruno Cardoso Lopes 1596c3d9b2 Remove elf specific info from ELFWriter.h to Elf.h. Code cleanup and more comments added 
llvm-svn: 72982
 2009-06-06 03:56:29 +00:00
Bruno Cardoso Lopes 12ad90a7a6 ELF Code Emitter now uses CurBufferPtr, BufferBegin and BufferEnd, as do JIT and 
MachO Writer. This will change with the arrival of ObjectCodeEmitter and
BinaryObject

Dan Gohman 9988569af8 Don't include <map> in Pass.h, which doesn't need it. This requires 
adding <map> to many files that actually do need it.

Gabor Greif e16561cd5d Here is the bulk of the sanitizing. 
Almost all occurrences of "bytecode" in the sources have been eliminated.

Devang Patel 8c78a0bff0 Drop 'const' 
llvm-svn: 36662
 2007-05-03 01:11:54 +00:00
Devang Patel e95c6ad802 Use 'static const char' instead of 'static const int'. 
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

llvm-svn: 36652
 2007-05-02 21:39:20 +00:00
Devang Patel 09f162ca6a Do not use typeinfo to identify pass in pass manager.
