2011-10-10Add support for dumping section headers to llvm-objdump. This uses the sameNick Lewycky
flags as binutils objdump but the output is different, not just in format but also showing different sections. Compare its results against readelf, not objdump. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141579 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-15use 64-bit types instead of off_t/size_t to avoid the issue whenIvan Krasin
gold plugin is built with Large File Support (sizeof(off_t) == 64 on i686) and the rest of LLVM is built w/o Large File Support (sizeof(off_t) == 32 on i686) which corrupts the stack. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139873 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-15Despite what the GCC wiki says, a quick search shows thatNick Lewycky
DW_AT_GNU_template_name = 0x2110, not 0x2108. That would explain those attr #0x2110 under the DW_TAG_GNU_template_template_param I'm seeing. Migrate from documented values to reality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139785 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-13Add the DataExtractor utility class.Benjamin Kramer
It is an endian-aware helper that can read data from a StringRef. It will come in handy for DWARF parsing. This class is inspired by LLDB's DataExtractor, but is stripped down to the bare minimum needed for DWARF. Comes with unit tests! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139626 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-12Initial commit of the 'landingpad' instruction.Bill Wendling
This implements the 'landingpad' instruction. It's used to indicate that a basic block is a landing pad. There are several restrictions on its use (see LangRef.html for more detail). These restrictions allow the exception handling code to gather the information it needs in a much more sane way. This patch has the definition, implementation, C interface, parsing, and bitcode support in it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137501 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-31Add the 'resume' instruction for the new EH rewrite.Bill Wendling
This adds the 'resume' instruction class, IR parsing, and bitcode reading and writing. The 'resume' instruction resumes propagation of an existing (in-flight) exception whose unwinding was interrupted with a 'landingpad' instruction (to be added later). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136589 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-29Misc optimizer+codegen work for 'cmpxchg' and 'atomicrmw'. They appear to beEli Friedman
working on x86 (at least for trivial testcases); other architectures will need more work so that they actually emit the appropriate instructions for orderings stricter than 'monotonic'. (As far as I can tell, the ARM, PPC, Mips, and Alpha backends need such changes.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136457 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-28LangRef and basic memory-representation/reading/writing for 'cmpxchg' andEli Friedman
'atomicrmw' instructions, which allow representing all the current atomic rmw intrinsics. The allowed operands for these instructions are heavily restricted at the moment; we can probably loosen it a bit, but supporting general first-class types (where it makes sense) might get a bit complicated, given how SelectionDAG works. As an initial cut, these operations do not support specifying an alignment, but it would be possible to add if we think it's useful. Specifying an alignment lower than the natural alignment would be essentially impossible to support on anything other than x86, but specifying a greater alignment would be possible. I can't think of any useful optimizations which would use that information, but maybe someone else has ideas. Optimizer/codegen support coming soon. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136404 91177308-0d34-0410-b5e6-96231b3b80d8
