Daniel Dunbar fe2d028ab1 build: Update CMakeLists.txt.

 2011-11-29 00:33:14 +00:00
Daniel Dunbar b074d102a3 edis: Sink EDMain.cpp into lib/MC/MCDisassembler. 
- This fixes some layering violations and matches how we handle the llvm-c lib,
   for example.

Evan Cheng ecb2908bf9 Sink codegen optimization level into MCCodeGenInfo along side relocation model 
and code model. This eliminates the need to pass OptLevel flag all over the
place and makes it possible for any codegen pass to use this information.

Bob Wilson 8d1c7dbdff Disable generation of compact unwind encodings. <rdar://problem/10441578> 
This still seems to be causing some failures.  It needs more testing before
it gets enabled again.

Daniel Dunbar 52823cc91c build: Attempt to rectify inconsistencies between CMake and LLVMBuild versions of explicit dependencies. 
- The hope is that we have a tool/test to verify these are accurate (and tight) soon.

Bob Wilson c391f7ff64 Remove FIXME comment that should have been removed with r144351.

Benjamin Kramer f554228d82 Clients are responsible for initializing the targets, remove it from the disassembler API. 
This will break users of the LLVMCreateDisasm API (not that I know of any). They have to call the 
LLVMInitializeAll* functions from llvm-c/Target.h themselves now. edis' C API in all its horribleness 
should be unaffected.

Daniel Dunbar b27317f7dd build/MCDisassembler: Fix required libraries list of MCDisassembler to use 
all-targets instead of an explicit list.

Benjamin Kramer 69d57cf9c4 Simplify some uses of utohexstr. 
As a side effect hex is printed lowercase instead of uppercase now.

Eric Christopher 4996c70034 Add the support code to enable the dwarf accelerator tables. Upcoming patches 
to fix the types section (all types, not just global types), and testcases.

The code to do the final emission is disabled by default.

Benjamin Kramer c74798d5cf Add an option to pad an uleb128 to MCObjectWriter and remove the uleb128 encoding from the DWARF asm printer. 
As a side effect we now print dwarf ulebs with .ascii directives.

Kevin Enderby 82ed3be1fb Fixed a bug in the code to create a dwarf file and directory table entires when 
it is separating the directory part from the basename of the FileName.  Noticed 
that this:

  .file 1 "dir/foo"

when assembled got the two parts switched.  Using the Mac OS X dwarfdump tool
it can be seen easily:

% dwarfdump -a a.out
include_directories[  1] = 'foo'
                Dir  Mod Time   File Len   File Name
                ---- ---------- ---------- ---------------------------
file_names[  1]    1 0x00000000 0x00000000 dir
...

Which should be:
...
include_directories[  1] = 'dir'
                Dir  Mod Time   File Len   File Name
                ---- ---------- ---------- ---------------------------
file_names[  1]    1 0x00000000 0x00000000 foo

Kevin Enderby 6469fc275a First part of support for generating dwarf for assembly source files with the 
-g flag.  In this part we generate the .file for the source being assembled and
the .loc's for the assembled instructions.

The next part will be to generate the dwarf Compile Unit DIE and a dwarf
subprogram DIE for each non-temporary label.

Once the next part is done test cases will be added.  rdar://9275556

Nick Lewycky 1a62d78325 On an ELF system, ".debug_str" is mergeable and contains null terminated strings 
composed of one byte characters.

Bruno Cardoso Lopes 82b077ec22 This is the first of several patches for Mips direct object generation. 
This first patch is for expression variable kinds.

Rafael Espindola e0d0908356 Fix parsing of a line with only a # in it. 
llvm-svn: 142537
 2011-10-19 18:48:52 +00:00
Nick Lewycky 40f8f2ff24 Add support for a new extension to the .file directive: 
.file filenumber "directory" "filename"

This removes one join+split of the directory+filename in MC internals. Because
bitcode files have independent fields for directory and filenames in debug info,
this patch may change the .o files written by existing .bc files.

Benjamin Kramer cc863b2bb6 Let printf do the formatting instead aligning strings ourselves. 
While at it, merge some format strings.

Benjamin Kramer 1930b003fe Add AsmToken::getEndLoc and use it to add ranges to x86 asm register parsing. 
<stdin>:1:12: error: register %rax is only available in 64-bit mode

Benjamin Kramer 47f5e30e78 PR11143: Save the old diagnostic handler and call it when munging diagnostics for #line directives. 
This reenables proper inline asm diagnostics in clang

Chris Lattner 7284526aff remove the dead 'ShowLine' argument from SMDiagnostic. 
llvm-svn: 142108
 2011-10-16 05:47:55 +00:00
Chris Lattner 03b80a4027 Make SMDiagnostic a little more sane. Instead of passing around note/warning/error as a 
string, pass it around as an enum.

llvm-svn: 142107
 2011-10-16 05:43:57 +00:00
Chris Lattner a3a0681083 Enhance llvm::SourceMgr to support diagnostic ranges, the same way clang does. Enhance 
the X86 asmparser to produce ranges in the one case that was annoying me, for example:

test.s:10:15: error: invalid operand for instruction
movl 0(%rax), 0(%edx)
              ^~~~~~~

It should be straight-forward to enhance filecheck, tblgen, and/or the .ll parser to use 
ranges where appropriate if someone is interested.

Owen Anderson 4a49dee221 Disable code/data region symbols on ELF targets, where different mapping symbols are used for ARM/Thumb mode code. This should only be re-enabled once we have a solution to properly distinguish these.

 2011-10-14 20:28:57 +00:00
Kevin Enderby e7c0c499b8 Finish supporting cpp #file/line comments in assembler for error messages. So 
for cpp pre-processed assembly we give correct filename and line numbers when
reporting errors in assembly files when using clang and -integrated-as on .s
files. rdar://8998895

Nick Lewycky 29e7b315ac Also create a shndx even if there are no symbols. This lets us test 
.symtab_shndx reading and writing together, and finally we have a testcase for
r141440.
