Nick Lewycky 1dcfe449ef Give this test an explicit triple.

Nick Lewycky 333449cd65 When emitting the PC range in an FDE, use the same data encoding for both ends 
of the range. Fixes PR13581!

Benjamin Kramer 6bee7f750d ELF: Add support for the asm .version directive.

Eli Bendersky f33086052d Continue cleanup of LIT, getting rid of the remaining artifacts from dejagnu 
* Removed test/lib/llvm.exp - it is no longer needed 
* Deleted the dg.exp reading code from test/lit.cfg. There are no dg.exp files
  left in the test suite so this code is no longer required. test/lit.cfg is
  now much shorter and clearer 
* Removed a lot of duplicate code in lit.local.cfg files that need access to
  the root configuration, by adding a "root" attribute to the TestingConfig
  object. This attribute is dynamically computed to provide the same
  information as was previously provided by the custom getRoot functions. 
* Documented the config.root attribute in docs/CommandGuide/lit.pod

David Meyer 1df4b84db4 In the ObjectFile interface, replace isInternal(), isAbsolute(), isGlobal(), and isWeak(), with a bitset of flags.

Rafael Espindola c22c85c29c On ELF, create relocations to the abbreviation and line sections when producing 
debug info for assembly files. We were already doing the right thing when
producing debug info for C/C++.

ELF linkers don't know dwarf, so they depend on these relocations to produce
valid dwarf output.

Eli Bendersky 924f9a671d Replace all instances of dg.exp file with lit.local.cfg, since all tests are run with LIT now and now Dejagnu. dg.exp is no longer needed. 
Patch reviewed by Daniel Dunbar. It will be followed by additional cleanup patches.

David Meyer 44ec69efe0 For ELF, also call fixSymbolsInTLSFixups() on expressions passed to EmitValue (literal values). Previously only called on expressions in instructions. New test cases added to tls.s, tls-i386.s. Resolves PR11981.

Rafael Espindola c7f355b8e1 Handle expressions of the form _GLOBAL_OFFSET_TABLE_-symbol the same way gas 
does. The _GLOBAL_OFFSET_TABLE_ is still magical in that we get a R_386_GOTPC,
but it doesn't change the immediate in the same way as when the expression
has no right hand side symbol.

 2011-12-10 02:28:43 +00:00
Rafael Espindola 7e0a793183 Handle reloc_signed_4byte in here. Not doing so was a regression from my 
previous commit. It is strange that we see it in 32 bits. We already
have a fixme about it.

llvm-svn: 146273
 2011-12-09 19:57:29 +00:00
Rafael Espindola 0a7f336475 Handle the case of the magical _GLOBAL_OFFSET_TABLE_ showing up in a 
symbol difference. This matches gas behavior and fixes PR11513.

We still don't handle _GLOBAL_OFFSET_TABLE_ in data sections.

Nick Lewycky 3e01bd3b60 Apparently, sometimes llvm-nm doesn't put the undefined symbol at the top. Take 
that into account and test for no U's showing up in the middle, which is what
we really wanted to test for.

llvm-svn: 141653
 2011-10-11 06:58:11 +00:00
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.

Rafael Espindola 0fc5e89c82 ADD64ri32 sign extends its argument, so we need to use a R_X86_64_32S. 
Fixes PR9934.

We really need to start tblgening the relocation info :-(

Rafael Espindola e90c1cb221 sets bit 0 of the function address of thumb function in .symtab 
("T is 1 if the target symbol S has type STT_FUNC and the
symbol addresses a Thumb instruction ;it is 0 otherwise."

Rafael Espindola 1557fd6d39 Write the section table and the section data in the same order that 
gun as does. This makes it a lot easier to compare the output of both

Eli Friedman d92d17bf67 PR9352: Always emit a relocation for weak symbols. Not emitting relocations 
for calls to weak symbols with a definition has the appearance of working
with LLVM-generated code because weak symbol definitions are put in their
own sections.

Chris Lattner 78178749e9 split this test into arch specific pieces, so the ARM
