2013-04-03Implements low-level object file format specific output for COFF andEric Christopher
ELF with support for: - File headers - Section headers + data - Relocations - Symbols - Unwind data (only COFF/Win64) The output format follows a few rules: - Values are almost always output one per line (as elf-dump/coff-dump already do). - Many values are translated to something readable (like enum names), with the raw value in parentheses. - Hex numbers are output in uppercase, prefixed with "0x". - Flags are sorted alphabetically. - Lists and groups are always delimited. Example output: ---------- snip ---------- Sections [ Section { Index: 1 Name: .text (5) Type: SHT_PROGBITS (0x1) Flags [ (0x6) SHF_ALLOC (0x2) SHF_EXECINSTR (0x4) ] Address: 0x0 Offset: 0x40 Size: 33 Link: 0 Info: 0 AddressAlignment: 16 EntrySize: 0 Relocations [ 0x6 R_386_32 .rodata.str1.1 0x0 0xB R_386_PC32 puts 0x0 0x12 R_386_32 .rodata.str1.1 0x0 0x17 R_386_PC32 puts 0x0 ] SectionData ( 0000: 83EC04C7 04240000 0000E8FC FFFFFFC7 |.....$..........| 0010: 04240600 0000E8FC FFFFFF31 C083C404 |.$.........1....| 0020: C3 |.| ) } ] ---------- snip ---------- Relocations and symbols can be output standalone or together with the section header as displayed in the example. This feature set supports all tests in test/MC/COFF and test/MC/ELF (and I suspect all additional tests using elf-dump), making elf-dump and coff-dump deprecated.

This reverts commit c8d65364223a04b179958a50a4bf0f89b21dd7d2. This broke a bunch of the buildbots. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178222 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-15Fix the FDE encoding to be relative on ELF.Rafael Espindola
This is a very late complement to r130637 which fixed this on x86_64. Fixes pr15448. Since it looks like that every elf architecture uses this encoding when using cfi, make it the default for elf. Just exclude mips64el. It has a lovely .ll -> .o test (ef_frame.ll) that tests that nothing changes in the binary content of the .eh_frame produced by llc. Oblige it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177141 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-09We need a shndx if the number of sections breaks SHN_LORESERVE. This conditionNick Lewycky
for choosing to emit a shndx was simply testing the wrong variable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176762 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-01Rewrite a test to check actual output rather than intermediate implementationEli Bendersky
detail. The was this test was written, it was relying on an implementation detail (fixups) and hence was very brittle (relying, among other things, on the exact ordering of statistics printed by MC). The test was rewritten to check a more observable output difference. While it doesn't cover 100% of the things the original test covered, it's a good practice to write regression tests this way. If we want to check that internal details and invariants hold, such tests should be expressed as unit tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176377 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-25Now that llvm-dwarfdump supports flags to specify which DWARF section to dump,Eli Bendersky
use them in tests that run llvm-dwarfdump. This is in order to make tests as specific as possible. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173498 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-17Prepare LLVM to fix PR14625, exposing a hook in MCContext to manage theChandler Carruth
compilation directory. This defaults to the current working directory, just as it always has, but now an assembler can choose to override it with a custom directory. I've taught llvm-mc about this option and added a test case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170371 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-25Add support for .cfi_register now that it is easy to extent the representationRafael Espindola
to support it. Original patch with the parsing and plumbing by the PaX team and Roman Divacky. I added the bits in MCDwarf.cpp and the test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168565 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-07MC: Overhaul handling of .lcommBenjamin Kramer
- Darwin lied about not supporting .lcomm and turned it into zerofill in the asm parser. Push the zerofill-conversion down into macho-specific code. - This makes the tri-state LCOMMType enum superfluous, there are no targets without .lcomm. - Do proper error reporting when trying to use .lcomm with alignment on a target that doesn't support it. - .comm and .lcomm alignment was parsed in bytes on COFF, should be power of 2. - Fixes PR13755 (.lcomm crashes on ELF). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163395 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-07PR13754: llvm-mc/x86 crashes on .cfi directives without the % prefix for ↵Benjamin Kramer
registers. gas accepts this and it seems to be common enough to be worth supporting. This doesn't affect the parsing of reg operands outside of .cfi directives. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163390 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-25Continue cleanup of LIT, getting rid of the remaining artifacts from dejagnuEli Bendersky
* 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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153408 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-28On ELF, create relocations to the abbreviation and line sections when producingRafael Espindola
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151655 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-16Replace all instances of dg.exp file with lit.local.cfg, since all tests are ↵Eli Bendersky
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150664 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-15For ELF, also call fixSymbolsInTLSFixups() on expressions passed to ↵David Meyer

2011-12-10Handle expressions of the form _GLOBAL_OFFSET_TABLE_-symbol the same way gasRafael Espindola
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146311 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-09Handle reloc_signed_4byte in here. Not doing so was a regression from myRafael Espindola
previous commit. It is strange that we see it in 32 bits. We already have a fixme about it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146273 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-09Handle the case of the magical _GLOBAL_OFFSET_TABLE_ showing up in aRafael Espindola
symbol difference. This matches gas behavior and fixes PR11513. We still don't handle _GLOBAL_OFFSET_TABLE_ in data sections. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146238 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-11Apparently, sometimes llvm-nm doesn't put the undefined symbol at the top. TakeNick Lewycky
that into account and test for no U's showing up in the middle, which is what we really wanted to test for. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141653 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-11Also create a shndx even if there are no symbols. This lets us testNick Lewycky
.symtab_shndx reading and writing together, and finally we have a testcase for r141440. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141641 91177308-0d34-0410-b5e6-96231b3b80d8
